Function Documentation

int ad_http_handler	(	short	event,
		ad_conn_t *	conn,
		void *	userdata
	)

HTTP protocol handler hook.

This hook provides an easy way to handle HTTP request/response.

Note: This hook must be registered at the top of hook chain.

ad_server_t *server = ad_server_new();

ad_server_register_hook(server, ad_http_handler, NULL);

Definition at line 84 of file ad_http_handler.c.

enum ad_http_request_status_e ad_http_get_status ( ad_conn_t * conn )

Return the request status.

Definition at line 116 of file ad_http_handler.c.

struct evbuffer* ad_http_get_inbuf ( ad_conn_t * conn )

Definition at line 123 of file ad_http_handler.c.

struct evbuffer* ad_http_get_outbuf ( ad_conn_t * conn )

Definition at line 128 of file ad_http_handler.c.

const char* ad_http_get_request_header	(	ad_conn_t *	conn,
		const char *	name
	)

Get request header.

Parameters

name	name of header.

Returns: value of string if found, otherwise NULL.

Definition at line 140 of file ad_http_handler.c.

off_t ad_http_get_content_length ( ad_conn_t * conn )

Return the size of content from the request.

Definition at line 148 of file ad_http_handler.c.

size_t ad_http_get_content_length_stored ( ad_conn_t * conn )

Return the actual size of data stored in in-buffer.

Definition at line 157 of file ad_http_handler.c.

void* ad_http_get_content	(	ad_conn_t *	conn,
		size_t	maxsize,
		size_t *	storedsize
	)

Remove content from the in-buffer.

The return data gets null terminated for convenience. For an example, if it reads 3 bytes, it will allocate 4 bytes and the 4th byte will be set to null terminator. storedsized will still return 3.

Parameters

maxsize	maximum length of data to read. 0 to read everything.
storedsize	the size of data read and stored in the return.

Definition at line 172 of file ad_http_handler.c.

int ad_http_is_keepalive_request ( ad_conn_t * conn )

Return whether the request is keep-alive request or not.

Returns: 1 if keep-alive request, otherwise 0.

Definition at line 199 of file ad_http_handler.c.

int ad_http_set_response_header	(	ad_conn_t *	conn,
		const char *	name,
		const char *	value
	)

Set response header.

Parameters

name	name of header.
value	value string to set. NULL to remove the header.

Returns: 0 on success, -1 if we already sent it out.

Definition at line 231 of file ad_http_handler.c.

const char* ad_http_get_response_header	(	ad_conn_t *	conn,
		const char *	name
	)

Parameters

name	name of header.

Returns: value of string if found, otherwise NULL.

Definition at line 254 of file ad_http_handler.c.

int ad_http_set_response_code	(	ad_conn_t *	conn,
		int	code,
		const char *	reason
	)

Returns: 0 on success, -1 if we already sent it out.

Definition at line 263 of file ad_http_handler.c.

int ad_http_set_response_content	(	ad_conn_t *	conn,
		const char *	contenttype,
		off_t	size
	)

Parameters

size	content size. -1 for chunked transfer encoding.

Returns: 0 on success, -1 if we already sent it out.

Definition at line 281 of file ad_http_handler.c.

size_t ad_http_response	(	ad_conn_t *	conn,
		int	code,
		const char *	contenttype,
		const void *	data,
		off_t	size
	)

Returns: total bytes sent, 0 on error.

Definition at line 308 of file ad_http_handler.c.

size_t ad_http_send_header ( ad_conn_t * conn )

Returns: 0 total bytes put in out buffer, -1 if we already sent it out.

Definition at line 331 of file ad_http_handler.c.

size_t ad_http_send_data	(	ad_conn_t *	conn,
		const void *	data,
		size_t	size
	)

Returns: 0 on success, -1 if we already sent it out.

Definition at line 367 of file ad_http_handler.c.

size_t ad_http_send_chunk	(	ad_conn_t *	conn,
		const void *	data,
		size_t	size
	)
