rtxHttpConnect()

EXTERNRT int rtxHttpConnect

(

OSRTNETCONN *

pNetConn

)

This function executes a full synchronous HTTP CONNECT request to setup a connection through a proxy.

Parameters

pNetConn

- Pointer to network connection structure.

Returns

- Operation status: 0 if success, negative code if error.

rtxHttpGet()

EXTERNRT int rtxHttpGet	(	OSCTXT *	pctxt,
		const char *	url,
		OSRTHttpContent *	pContent
	)

This function executes a full synchronous HTTP GET request.

A network connection is opened and a GET request sent to the given URL. The response is then read and returned, after which the network connection is closed.

Parameters

pctxt	- Pointer to context structure.
url	- Full URL of get request.
pContent	- Pointer to content buffer to receive response.

Returns

- Operation status: 0 if success, negative code if error.

rtxHttpRecvContent()

EXTERNRT int rtxHttpRecvContent	(	OSRTNETCONN *	pNetConn,
		OSRTHttpHeader *	pHeader,
		OSRTHttpContent *	pContent
	)

This function receives HTTP content.

All content associated with the response header is stored in the given memory buffer.

Parameters

pNetConn	- Pointer to network connection structure.
pHeader	- Pointer to response header structure describing content.
pContent	- Buffer to receive content. Dynamic memory is allocated for the content using the rtxMemAlloc function.

Returns

- Operation status: 0 if success, negative code if error.

rtxHttpRecvRespContent()

EXTERNRT int rtxHttpRecvRespContent	(	OSRTNETCONN *	pNetConn,
		OSRTHttpHeader *	pHeader,
		OSRTHttpContent *	pContent
	)

This function receives any HTTP content indicated by the response header.

If the header does not indicate any additional content, the function does nothing.

Parameters

pNetConn	- Pointer to network connection structure.
pHeader	- Pointer to response header structure describing content.
pContent	- Buffer to receive content. Dynamic memory is allocated for the content using the rtxMemAlloc function.

Returns

- Operation status: 0 if success, negative code if error.

rtxHttpRecvRespHdr()

EXTERNRT int rtxHttpRecvRespHdr	(	OSRTNETCONN *	pNetConn,
		OSRTHttpHeader *	pHeader
	)

This function receives the initial header returned from an HTTP request.

The header response information is returned in the header structure.

Parameters

pNetConn	- Pointer to network connection structure.
pHeader	- Pointer to header structure to receive returned data.

Returns

- Operation status: 0 if success, negative code if error.

rtxHttpSendGetRequest()

EXTERNRT int rtxHttpSendGetRequest	(	OSRTNETCONN *	pNetConn,
		const char *	url
	)

This function sends an HTTP GET request to a network connection.

Parameters

pNetConn	- Pointer to network connection structure.
url	- Full URL of get request. May be set to NULL if URL was provided earlier in rtxNetInitConn function call.

Returns

- Operation status: 0 if success, negative code if error.

rtxHttpSendRequest()

EXTERNRT int rtxHttpSendRequest	(	OSRTNETCONN *	pNetConn,
		const char *	method,
		const char *	content,
		const char *	contentType
	)

This function sends an HTTP request to a network connection.

Parameters

pNetConn	- Pointer to network connection structure.
method	- HTTP method to be used for request (GET or POST)
content	- Content to be sent after header.
contentType	- Type of content.

Returns

- Operation status: 0 if success, negative code if error.
