WebParseResponseStatus Function

Action

Parses the response header status line if a variable is specified as an out parameter. The subsequent low-level web function will NOT return until the request has finished. Other requests started before may run in parallel. This function might be used, for example, to avoid errors during an authentication handshake.

It is important to know that all parsing and verification functions must be specified before the Web API call for which the response data should be parsed/verified. You can specify multiple parse/verification functions before a Web API call. The order of the parse/verification functions is not relevant (Exception: WebParseDataBound and WebVerifyDataBound using the flag WEB_FLAG_SYNCHRON).

注: This function avoids an error only once. After the specified error occurred, another WebParseResponseStatus function call is necessary.

注: If you want to parse a Web document, you must first call the WebParseResponseStatus function. Then you call the function which retrieves the document.

注: This function is obsolete. It can still be used, although it's recommended to use the WebIgnoreServerError function instead.
