Documentation
An exception that occurs during an HTTP exchange.
Constructors
| Http !HttpException | The response was not a valid HTTP response |
| Send !SendException | Transport exception while sending. When backed by stream sockets,
exceptions like |
| Receive !ReceiveException | Transport exception while receiving. Depending on the backend, this may or may not include an end-of-input exception. For stream sockets, end-of-input is not presented as an exception. It is presented as a zero-length result. |

exchange :: Resource -> Bodied Request -> M (Either Exception (Bodied Response)) Source #
Send an HTTP request and await a response. This function takes
responsibility for encoding the request and decoding the response.
It deals with the Transfer-Encoding of the response and supports
both chunked and nonchunked responses.
exchangeDiscardBody :: Resource -> Bodied Request -> M (Either Exception Response) Source #
Variant of exchange that discards the response body. This can be
used safely even when the size of the response body is greater than
the amount of memory available.
This is intended as a resident-memory optimization for situations where the caller ignores the response body.
