Detailed Description

Header for the HTTP client

HTTP client interface functions can return APR_PAA_HTTP_ERROR to indicate there was error in the underlying HTTP library. Since the underlying HTTP library likely has numerous error conditions, a standard approach for dealing with this situation is to log the specific error condition and return the generic APR_PAA_HTTP_ERROR to the caller.

typedef size_t(* paa_resp_body_cb) (const unsigned char *src, size_t size, void *userdata)

Defines a callback for response body data. This callback can expect the data to be in the same format that it would appear on the wire. For example, if the response uses a chunked transfer-encoding, the data passed to this callback would already be in the chunked transfer-encoding.

srcthe data
sizethe size of the data. A size of 0 should be used to indicate the end of the body.
the number of bytes actual consumed. A value less than size indicates an error condition.
typedef void(* paa_resp_header_cb) (const char *name, const char *value, void *userdata)

Defines a callback for response header data. Callers do not need to worry about combining multiple headers with the same name into one distinct header.

namethe name of the header
valuethe value of the header

typedef void(* paa_resp_status_cb) (unsigned int status, const char *reason, void *userdata)

Defines a callback for response status data.

statusthe status of the response
reasonthe reason string from the response. This data should be allocated in the response memory pool.
