c++httpPost实现

前些天工作中用到了调用Java的http接口,因此在网上查找了一些资料,实现了一个简单的httppost方法,用到的是libcurl库,资源可以在我的资源中下载,具体代码如下:

#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include "./libcurl/include/curl.h"
#include "./libcurl/include/easy.h"
using namespace std;


int sendByHttpPost(const char *callbackUrl, string responcexml)
{
    CURL * curl;
    struct curl_slist *headerlist=NULL;
    headerlist = curl_slist_append(headerlist, "Content-Type:application/octet-stream");
    //初始化libcurl库，想用libcurl库的函数就必须首先初始化libcurl
    CURLcode code = curl_global_init(CURL_GLOBAL_ALL);
    if(CURLE_OK != code)
        return -1;


    //初始化easy interface，想使用easy interface的api函数就必须首先初始化easy interface
    curl = curl_easy_init();
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist);
    //curl_easy_setopt(curl, CURLOPT_HTTPHEADER,"Content-Type:application/octet-stream");
    curl_easy_setopt(curl, CURLOPT_URL, callbackUrl);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, responcexml.c_str());
    curl_easy_perform(curl);
    curl_easy_cleanup(curl);//释放资源
    curl_global_cleanup();//释放资源

    if (headerlist)
    {
        //delete headerlist;
        curl_slist_free_all(headerlist);
        headerlist = NULL;
    }

    return 0;
}


int main(int argc, char **argv)
{
    const char *callbackUrl =     "http://192.168.0.135:8080/basin/publiscollback/publiscollback_updateSendUserStatus.action";
    string test = "测试信息";
    if(sendByHttpPost(callbackUrl, test) < 0)
        return -1;
    system("pause");
    return 0;
}
