Then you probably didn't format the data the way the receiver expected it.
i jz wonder if my POST data is correct or not. I jz pass the
multipart/form-data to CURLOPT_POSTFIELDS, will curl use my data or change
it ?
libcurl will pass along the data *exactly* the way you give it to libcurl:
http://curl.haxx.se/libcurl/c/CURLOPT_POSTFIELDS.html
but of course the rqeuest headers may also be important.
Use CURLOPT_DEBUGFUNCTION (or wireshark) to get a full trace of what your
request looks like to make sure it looks the way you intended it to.
