Methods

checkVersion

checkVersion Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Word32

major: the major version to check

-> Word32

minor: the minor version to check

-> Word32

micro: the micro version to check

-> m Bool

Returns: True if the version of the libsoup currently loaded is the same as or newer than the passed-in version.

Like [funccHECKVERSION], but the check for soup_check_version is at runtime instead of compile time.

This is useful for compiling against older versions of libsoup, but using features from newer versions.

cookiesFromRequest

cookiesFromRequest Source #

Arguments

:: (HasCallStack, MonadIO m, IsMessage a) 
=> a

msg: a Message containing a "Cookie" request header

-> m [Cookie]

Returns: a SList of SoupCookies, which can be freed with [methodcookie.free].

Parses msg's Cookie request header and returns a [structgLib.SList] of SoupCookies.

As the "Cookie" header, unlike "Set-Cookie", only contains cookie names and values, none of the other Cookie fields will be filled in. (Thus, you can't generally pass a cookie returned from this method directly to [funccookiesToResponse].)

cookiesFromResponse

cookiesFromResponse Source #

Arguments

:: (HasCallStack, MonadIO m, IsMessage a) 
=> a

msg: a Message containing a "Set-Cookie" response header

-> m [Cookie]

Returns: a SList of SoupCookies, which can be freed with [methodcookie.free].

Parses msg's Set-Cookie response headers and returns a [structgLib.SList] of SoupCookies.

Cookies that do not specify "path" or "domain" attributes will have their values defaulted from msg.

cookiesToCookieHeader

cookiesToCookieHeader Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> [Cookie]

cookies: a SList of Cookie

-> m Text

Returns: the serialization of cookies

Serializes a [structgLib.SList] of Cookie into a string suitable for setting as the value of the "Cookie" header.

cookiesToRequest

cookiesToRequest Source #

Arguments

:: (HasCallStack, MonadIO m, IsMessage a) 
=> [Cookie]

cookies: a SList of Cookie

-> a

msg: a Message

-> m () 

Adds the name and value of each cookie in cookies to msg's "Cookie" request.

If msg already has a "Cookie" request header, these cookies will be appended to the cookies already present. Be careful that you do not append the same cookies twice, eg, when requeuing a message.

cookiesToResponse

cookiesToResponse Source #

Arguments

:: (HasCallStack, MonadIO m, IsMessage a) 
=> [Cookie]

cookies: a SList of Cookie

-> a

msg: a Message

-> m () 

Appends a "Set-Cookie" response header to msg for each cookie in cookies.

This is in addition to any other "Set-Cookie" headers msg may already have.

dateTimeNewFromHttpString

dateTimeNewFromHttpString Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

dateString: The date as a string

-> m (Maybe DateTime)

Returns: a new DateTime, or Nothing if dateString could not be parsed.

Parses dateString and tries to extract a date from it.

This recognizes all of the "HTTP-date" formats from RFC 2616, RFC 2822 dates, and reasonable approximations thereof. (Eg, it is lenient about whitespace, leading "0"s, etc.)

dateTimeToString

dateTimeToString Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> DateTime

date: a DateTime

-> DateFormat

format: the format to generate the date in

-> m Text

Returns: date as a string or Nothing

Converts date to a string in the format described by format.

formEncodeDatalist

formEncodeDatalist Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Data

formDataSet: a datalist containing name/value pairs

-> m Text

Returns: the encoded form

Encodes formDataSet into a value of type "application/x-www-form-urlencoded".

Encodes as defined in the HTML 4.01 spec. Unlike [funcformEncodeHash], this preserves the ordering of the form elements, which may be required in some situations.

See also: [ctormessage.new_from_encoded_form].

formEncodeHash

formEncodeHash Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Map Text Text

formDataSet: a hash table containing name/value pairs (as strings)

-> m Text

Returns: the encoded form

Encodes formDataSet into a value of type "application/x-www-form-urlencoded".

Encodes as defined in the HTML 4.01 spec.

Note that the HTML spec states that "The control names/values are listed in the order they appear in the document." Since this method takes a hash table, it cannot enforce that; if you care about the ordering of the form fields, use [funcformEncodeDatalist].

See also: [ctormessage.new_from_encoded_form].

getMajorVersion

getMajorVersion Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> m Word32

Returns: the major version number of the libsoup library

Returns the major version number of the libsoup library.

e.g. in libsoup version 2.42.0 this is 2.

This function is in the library, so it represents the libsoup library your code is running against. Contrast with the MAJOR_VERSION macro, which represents the major version of the libsoup headers you have included when compiling your code.

getMicroVersion

getMicroVersion Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> m Word32

Returns: the micro version number of the libsoup library

Returns the micro version number of the libsoup library.

e.g. in libsoup version 2.42.0 this is 0.

This function is in the library, so it represents the libsoup library your code is running against. Contrast with the MICRO_VERSION macro, which represents the micro version of the libsoup headers you have included when compiling your code.

getMinorVersion

getMinorVersion Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> m Word32

Returns: the minor version number of the libsoup library

Returns the minor version number of the libsoup library.

e.g. in libsoup version 2.42.0 this is 42.

This function is in the library, so it represents the libsoup library your code is running against. Contrast with the MINOR_VERSION macro, which represents the minor version of the libsoup headers you have included when compiling your code.

headerContains

headerContains Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

header: An HTTP header suitable for parsing with [funcheaderParseList]

-> Text

token: a token

-> m Bool

Returns: whether or not header contains token

Parses header to see if it contains the token token (matched case-insensitively).

Note that this can't be used with lists that have qvalues.

headerFreeParamList

headerFreeParamList Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Map Text Text

paramList: a HashTable returned from [funcheaderParseParamList] or [funcheaderParseSemiParamList]

-> m () 

Frees paramList.

headerGStringAppendParam

headerGStringAppendParam Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> String

string: a String being used to construct an HTTP header value

-> Text

name: a parameter name

-> Maybe Text

value: a parameter value, or Nothing

-> m () 

Appends something like name=value to string, taking care to quote value if needed, and if so, to escape any quotes or backslashes in value.

Alternatively, if value is a non-ASCII UTF-8 string, it will be appended using RFC5987 syntax. Although in theory this is supposed to work anywhere in HTTP that uses this style of parameter, in reality, it can only be used portably with the Content-Disposition "filename" parameter.

If value is Nothing, this will just append name to string.

headerGStringAppendParamQuoted

headerGStringAppendParamQuoted Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> String

string: a String being used to construct an HTTP header value

-> Text

name: a parameter name

-> Text

value: a parameter value

-> m () 

Appends something like name="value" to string, taking care to escape any quotes or backslashes in value.

If value is (non-ASCII) UTF-8, this will instead use RFC 5987 encoding, just like [funcheaderGStringAppendParam].

headerParseList

headerParseList Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

header: a header value

-> m [Text]

Returns: a SList of list elements, as allocated strings

Parses a header whose content is described by RFC2616 as #something.

"something" does not itself contain commas, except as part of quoted-strings.

headerParseParamList

headerParseParamList Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

header: a header value

-> m (Map Text Text)

Returns: a HashTable of list elements, which can be freed with [funcheaderFreeParamList].

Parses a header which is a comma-delimited list of something like: token [ "=" ( token | quoted-string ) ].

Tokens that don't have an associated value will still be added to the resulting hash table, but with a Nothing value.

This also handles RFC5987 encoding (which in HTTP is mostly used for giving UTF8-encoded filenames in the Content-Disposition header).

headerParseParamListStrict

headerParseParamListStrict Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

header: a header value

-> m (Maybe (Map Text Text))

Returns: a HashTable of list elements, which can be freed with [funcheaderFreeParamList] or Nothing if there are duplicate elements.

A strict version of [funcheaderParseParamList] that bails out if there are duplicate parameters.

Note that this function will treat RFC5987-encoded parameters as duplicated if an ASCII version is also present. For header fields that might contain RFC5987-encoded parameters, use [funcheaderParseParamList] instead.

headerParseQualityList

headerParseQualityList Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

header: a header value

-> m ([Text], [Text])

Returns: a SList of acceptable values (as allocated strings), highest-qvalue first.

Parses a header whose content is a list of items with optional "qvalue"s (eg, Accept, Accept-Charset, Accept-Encoding, Accept-Language, TE).

If unacceptable is not Nothing, then on return, it will contain the items with qvalue 0. Either way, those items will be removed from the main list.

headerParseSemiParamList

headerParseSemiParamList Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

header: a header value

-> m (Map Text Text)

Returns: a HashTable of list elements, which can be freed with [funcheaderFreeParamList].

Parses a header which is a semicolon-delimited list of something like: token [ "=" ( token | quoted-string ) ].

Tokens that don't have an associated value will still be added to the resulting hash table, but with a Nothing value.

This also handles RFC5987 encoding (which in HTTP is mostly used for giving UTF8-encoded filenames in the Content-Disposition header).

headerParseSemiParamListStrict

headerParseSemiParamListStrict Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

header: a header value

-> m (Maybe (Map Text Text))

Returns: a HashTable of list elements, which can be freed with [funcheaderFreeParamList] or Nothing if there are duplicate elements.

A strict version of [funcheaderParseSemiParamList] that bails out if there are duplicate parameters.

Note that this function will treat RFC5987-encoded parameters as duplicated if an ASCII version is also present. For header fields that might contain RFC5987-encoded parameters, use [funcheaderParseSemiParamList] instead.

headersParse

headersParse Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

str: the header string (including the Request-Line or Status-Line, but not the trailing blank line)

-> Int32

len: length of str

-> MessageHeaders

dest: MessageHeaders to store the header values in

-> m Bool

Returns: success or failure

Parses the headers of an HTTP request or response in str and stores the results in dest.

Beware that dest may be modified even on failure.

This is a low-level method; normally you would use [funcheadersParseRequest] or [funcheadersParseResponse].

headersParseRequest

headersParseRequest Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

str: the headers (up to, but not including, the trailing blank line)

-> Int32

len: length of str

-> MessageHeaders

reqHeaders: MessageHeaders to store the header values in

-> m (Word32, Text, Text, HTTPVersion)

Returns: StatusOk if the headers could be parsed, or an HTTP error to be returned to the client if they could not be.

Parses the headers of an HTTP request in str and stores the results in reqMethod, reqPath, ver, and reqHeaders.

Beware that reqHeaders may be modified even on failure.

headersParseResponse

headersParseResponse Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

str: the headers (up to, but not including, the trailing blank line)

-> Int32

len: length of str

-> MessageHeaders

headers: MessageHeaders to store the header values in

-> m (Bool, HTTPVersion, Word32, Text)

Returns: success or failure.

Parses the headers of an HTTP response in str and stores the results in ver, statusCode, reasonPhrase, and headers.

Beware that headers may be modified even on failure.

headersParseStatusLine

headersParseStatusLine Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

statusLine: an HTTP Status-Line

-> m (Bool, HTTPVersion, Word32, Text)

Returns: True if statusLine was parsed successfully.

Parses the HTTP Status-Line string in statusLine into ver, statusCode, and reasonPhrase.

statusLine must be terminated by either "\0" or "\r\n".

tldDomainIsPublicSuffix

tldDomainIsPublicSuffix Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

domain: a domain name

-> m Bool

Returns: True if it is a public domain, False otherwise.

Looks whether the domain passed as argument is a public domain suffix (.org, .com, .co.uk, etc) or not.

Prior to libsoup 2.46, this function required that domain be in UTF-8 if it was an IDN. From 2.46 on, the name can be in either UTF-8 or ASCII format.

tldGetBaseDomain

tldGetBaseDomain Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

hostname: a hostname

-> m Text

Returns: a pointer to the start of the base domain in hostname. If an error occurs, Nothing will be returned and error set. (Can throw GError)

Finds the base domain for a given hostname

The base domain is composed by the top level domain (such as .org, .com, .co.uk, etc) plus the second level domain, for example for myhost.mydomain.com it will return mydomain.com.

Note that Nothing will be returned for private URLs (those not ending with any well known TLD) because choosing a base domain for them would be totally arbitrary.

Prior to libsoup 2.46, this function required that hostname be in UTF-8 if it was an IDN. From 2.46 on, the name can be in either UTF-8 or ASCII format (and the return value will be in the same format).

uriDecodeDataUri

uriDecodeDataUri Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Text

uri: a data URI, in string form

-> m (Bytes, Maybe Text)

Returns: a Bytes with the contents of uri, or Nothing if uri is not a valid data URI

Decodes the given data URI and returns its contents and contentType.

uriEqual

uriEqual Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Uri

uri1: a Uri

-> Uri

uri2: another Uri

-> m Bool

Returns: True if equal otherwise False

Tests whether or not uri1 and uri2 are equal in all parts.

websocketClientPrepareHandshake

websocketClientPrepareHandshake Source #

Arguments

:: (HasCallStack, MonadIO m, IsMessage a) 
=> a

msg: a Message

-> Maybe Text

origin: the "Origin" header to set

-> Maybe [Text]

protocols: list of protocols to offer

-> Maybe [TypeClass]

supportedExtensions: list of supported extension types

-> m () 

Adds the necessary headers to msg to request a WebSocket handshake including supported WebSocket extensions.

The message body and non-WebSocket-related headers are not modified.

This is a low-level function; if you use [methodsession.websocket_connect_async] to create a WebSocket connection, it will call this for you.

websocketClientVerifyHandshake

websocketClientVerifyHandshake Source #

Arguments

:: (HasCallStack, MonadIO m, IsMessage a) 
=> a

msg: Message containing both client and server sides of a WebSocket handshake

-> Maybe [TypeClass]

supportedExtensions: list of supported extension types

-> m [WebsocketExtension]

(Can throw GError)

Looks at the response status code and headers in msg and determines if they contain a valid WebSocket handshake response (given the handshake request in msg's request headers).

If supportedExtensions is non-Nothing, extensions included in the response "Sec-WebSocket-Extensions" are verified too. Accepted extensions are returned in acceptedExtensions parameter if non-Nothing.

This is a low-level function; if you use [methodsession.websocket_connect_async] to create a WebSocket connection, it will call this for you.

websocketServerCheckHandshake

websocketServerCheckHandshake Source #

Arguments

:: (HasCallStack, MonadIO m, IsServerMessage a) 
=> a

msg: ServerMessage containing the client side of a WebSocket handshake

-> Maybe Text

origin: expected Origin header

-> Maybe [Text]

protocols: allowed WebSocket protocols.

-> Maybe [TypeClass]

supportedExtensions: list of supported extension types

-> m ()

(Can throw GError)

Examines the method and request headers in msg and determines whether msg contains a valid handshake request.

If origin is non-Nothing, then only requests containing a matching "Origin" header will be accepted. If protocols is non-Nothing, then only requests containing a compatible "Sec-WebSocket-Protocols" header will be accepted. If supportedExtensions is non-Nothing, then only requests containing valid supported extensions in "Sec-WebSocket-Extensions" header will be accepted.

Normally [funcwebsocketServerProcessHandshake] will take care of this for you, and if you use [methodserver.add_websocket_handler] to handle accepting WebSocket connections, it will call that for you. However, this function may be useful if you need to perform more complicated validation; eg, accepting multiple different Origins, or handling different protocols depending on the path.

websocketServerProcessHandshake

websocketServerProcessHandshake Source #

Arguments

:: (HasCallStack, MonadIO m, IsServerMessage a) 
=> a

msg: ServerMessage containing the client side of a WebSocket handshake

-> Maybe Text

expectedOrigin: expected Origin header

-> Maybe [Text]

protocols: allowed WebSocket protocols.

-> Maybe [TypeClass]

supportedExtensions: list of supported extension types

-> m (Bool, [WebsocketExtension])

Returns: True if msg contained a valid WebSocket handshake request and was updated to contain a handshake response. False if not.

Examines the method and request headers in msg and (assuming msg contains a valid handshake request), fills in the handshake response.

If expectedOrigin is non-Nothing, then only requests containing a matching "Origin" header will be accepted. If protocols is non-Nothing, then only requests containing a compatible "Sec-WebSocket-Protocols" header will be accepted. If supportedExtensions is non-Nothing, then only requests containing valid supported extensions in "Sec-WebSocket-Extensions" header will be accepted. The accepted extensions will be returned in acceptedExtensions parameter if non-Nothing.

This is a low-level function; if you use [methodserver.add_websocket_handler] to handle accepting WebSocket connections, it will call this for you.
