Function Documentation

struct http_response* http_request_get	(	struct network_conn *	nwc,
		char *	url,
		char *	host
	)

Send an HTTP request and read the header along with the body.

Behaves similar to http_request_get_only_header(), but with the following differences:

• follow at max. MAX_REDIRECT_STEPS
• read everything the server sends (header + body)

Parameters

nwc	The network-connection to use
url	The URL to request.
host	The host.

Returns

A pointer to an http_response, or NULL in case of error.

struct http_response* http_request_get_only_header	(	struct network_conn *	nwc,
		char *	url,
		char *	host,
		size_t	follow_redirect_steps
	)

Send an HTTP request to host using nwc and reads the header.

http_request_get_only_header() expects nwc to be connected to the correct server. The parameters url and host are only used for the request itself, as shown below:

GET <url> HTTP/1.1\r\n
Host: <host>\r\n\r\n

Take care: The returned http_response may contain a different nwc than the original passed one. In this case the body needs to be read from the returned http_response::nwc.

Parameters

nwc	The network-connection to use
url	The URL to request.
host	The host.
follow_redirect_steps	The number of redirects allowed (0 = disable rediects).

Returns

A pointer to an http_response, or NULL in case of error.

void http_response_destroy

(

struct http_response *

resp

)

This function only frees data, it does not free the connection nwc itself.

Parameters

resp	The http_response to free
