Hello Friends,

I hv a requirement of connecting to a site and upload binary/text file.

From the MSDOS command prompt using curl.exe the login and upload is
perfectly working. But login and upload using libcurl from C++ application
is failing.

Platform is Windows XP

----- COMMAND LINE Curl EXECUTION BEGIN -----

######## LogIn ########

curl -c cookies.txt -A "PWCAutoUploader 0.1" -o
requestOutput/loginResult.html -d
"userName=x&password=y&portalUser=N&serviceCompanyId=-1"
http://utcit-190:9999/webectm/logon.do

######## UpLoad ########

curl -b cookies.txt -A "PWCAutoUploader 0.1" -o
requestOutput/uploadResult.html -F "type=GBSStandardFile" -F
"theFile=@GK-Nov-05-1-D004000_.SSS"
http://utcit-190:9999/webectm/loadEngineFileToDB.do

----- COMMAND LINE Curl EXECUTION END -----

The same above operations of login and upload when done using libcurl in C++
program the login process is success but the upload is failing. The upload
is http post method and i a using the sample code explained in
http://curl.haxx.se/libcurl/c/libcurl-tutorial.html in HTTP POSTing section.
Please suggest me if i am doing anthing wrong. The C++ code is below :

//////////////// C++ CODE FileUpload - BEGIN//////////////////////////////

// HelloCurl.cpp : Defines the entry point for the console application.

#include <stdio.h>

#include <curl/curl.h>

#include <iostream>

#include <fstream>

#include <string>

using namespace std;

string contents;

ofstream
strmLoginResponse("E:\\cURL\\curl-7.19.0\\src\\DLL-Debug\\Project\\HelloCurl
\\GKLoginResponse.yxt");

size_t WriteMemoryCallbackStdString(void *ptr, size_t size, size_t

nmemb, void *data)

{

contents = *(string *)(data);

contents.append((char *)ptr, realsize);

if (strmLoginResponse.is_open())

{

strmLoginResponse << contents.c_str();

}

cout << " WriteMemoryCallBackStdString : " << contents.c_str()
<< endl;

strmLoginResponse.close();

return realsize;

}

int main(void)

{

CURL *curl;

CURLcode res;

string strCookiesFile =
"E:\\cURL\\curl-7.19.0\\src\\DLL-Debug\\Project\\HelloCurl\\Cookies.txt";

string strUserAgent = "PWCAutoUploader 0.1";

curl = curl_easy_init();

if (curl)

{

/////// WebECTM Login - BEGIN//////////////////////////////////////

curl_easy_setopt(curl, CURLOPT_COOKIEJAR,
strCookiesFile.c_str());

curl_easy_setopt(curl, CURLOPT_USERAGENT, strUserAgent.c_str());

curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION,
WriteMemoryCallbackStdString);

// curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, NULL);

// curl_easy_setopt(curl, CURLOPT_WRITEDATA, fpLoginResponse);

curl_easy_setopt(curl, CURLOPT_URL,

/* Now specify the POST data */

curl_easy_setopt(curl, CURLOPT_POSTFIELDS,
"userName=a&password=a&portalUser=N&serviceCompanyId=-1");

curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);

/* Perform the request, res will get the return code */

res = curl_easy_perform(curl);

/////// WebECTM Login - END //////////////////////////////////////

curl_easy_setopt(curl, CURLOPT_COOKIEFILE, strCookiesFile.c_str());

curl_easy_setopt(curl, CURLOPT_USERAGENT, strUserAgent.c_str());

curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION,
WriteMemoryCallbackStdString);

curl_easy_setopt(curl, CURLOPT_URL,

curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);

struct curl_httppost *post=NULL;

struct curl_httppost *last=NULL;

curl_formadd(&post, &last,

CURLFORM_COPYNAME, "type",

CURLFORM_COPYCONTENTS,
"GBSStandardFile", CURLFORM_END);

curl_formadd(&post, &last,

CURLFORM_COPYNAME,
"theFile",

CURLFORM_FILECONTENT,
"GK-Nov-05-1-D004000_.SSS", CURLFORM_END);

/* Set the form info */

curl_easy_setopt(curl, CURLOPT_HTTPPOST, post);

curl_easy_perform(curl); /* post away! */

/* free the post data again */

curl_formfree(post);

curl_easy_cleanup(curl);

/// UpLoad END /////

}

return 0;

}
