Question

我想我已经在stackoverflow上阅读了每个libcurl帖子相关的问题，但我仍然无法让我的登录代码工作。我复制了其他示例帖子程序中的代码以及来自https://www.hackthissite.org/articles/read/1078的代码它仍然无法正常工作。代码本身没有错误，但最终的get会保持重定向到https://www.masteringbiology.com/site/notloggedin.html。我正在尝试登录并使用cookie访问网站上的特定页面。我100％自学成才，非常感谢帮助。

#include <stdio.h>
#include <iostream>
#include <curl\curl.h>
#include<fstream>
#include <cstdio>
#include <stdlib.h>
using namespace std;
int main(void)
{
CURLcode res;
// string URL= "https://session.masteringbiology.com/myct/assignmentPrintViewassignmentID=6607103";
CURL* curly= curl_easy_init();
curl_global_init(CURL_GLOBAL_ALL);
if(curly){
    cout<<"go!!!"<<endl;
curl_easy_setopt(curly, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(curly, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_easy_setopt(curly, CURLOPT_USERAGENT, "Mozilla/4.0");
curl_easy_setopt(curly, CURLOPT_AUTOREFERER, 1 );
curl_easy_setopt(curly, CURLOPT_FOLLOWLOCATION, 1 );
curl_easy_setopt(curly, CURLOPT_COOKIEFILE, "");
curl_easy_setopt(curly, CURLOPT_URL, 
"https://www.masteringbiology.com/site/login.html");
curl_easy_perform( curly );
// Now, can actually login. First we forge the HTTP referer field
curl_easy_setopt(curly, CURLOPT_REFERER, 
"https://www.masteringbiology.com/site/login.html");
// Next we tell LibCurl what HTTP POST data to submit
char *data="nme=xxx&pwd=yyy";
curl_easy_setopt(curly, CURLOPT_POSTFIELDS, data);
curl_easy_perform( curly );

//todoc
curl_easy_setopt(curly, CURLOPT_HTTPGET, 1L);
   //curl_easy_setopt(curly, CURLOPT_URL, URL.c_str());
    curl_easy_setopt(curly, CURLOPT_URL, 
"https://session.masteringbiology.com/myct/mastering#/");
    FILE * filename1;
filename1=fopen("filetest.txt","w+");
if(filename1) {
// write the page body to this file handle
 curl_easy_setopt(curly, CURLOPT_WRITEDATA, filename1);

// get it!
res=curl_easy_perform(curly);

// close the header file
fclose(filename1);
}

if (res==CURLE_OK){
cout<<"Yeah!!!";
}
else{cout<<"oh no!!! "<<res;}
}
else{
    fprintf(stderr, "curl initialization failure");
return 0;
    }
curl_easy_cleanup(curly);
return 0;
}
