1.下载最新版的libcurl,并解压。(本例以vs2013 + curl-7.52.1.zip为例)
2.打开VS2013 开发人员命令提示,并CD进入 curl-curl-7_52_1/winbuild/ 目录
VS生成代码的时候有一个运行库选项(项目属性 - 配置属性 - C/C++ - 代码生成 - 运行库)/MT和/MD(/MTd和/MDd是对应的debug版本)
就是说你编译时如果加了RTLIBCFG=static这个选项,就相当于编译了/MT版本的libcurl,否则是/MD版本的
nmake /f Makefile.vc mode=static VC=12 RTLIBCFG=static
完成编译后libcurl静态库会出现在builds目录下包括头文件和libcurl_a.lib,我们需要的是builds/libcurl-vc12-x86-release-static-ipv6-sspi-winssl下面的include和lib两个文件夹
3.测试
项目->属性->c/c++ ->代码生成->运行库->/MT
// curl_test.cpp : 定义控制台应用程序的入口点。#define CURL_STATICLIB#include#include #pragma comment(lib, "libcurl_a.lib")using namespace std;/*** 一旦curl接收到数据,就会调用此回调函数* buffer:数据缓冲区指针* size:调试阶段总是发现为1* nmemb:(memory block)代表此次接受的内存块的长度* userp:用户自定义的一个参数*/size_t write_data(void* buffer, size_t size, size_t nmemb, void* userp){ static int current_index = 0; cout << "current:" << current_index++; cout << (char*)buffer; cout << "---------------" << endl; int temp = *(int*)userp; // 这里获取用户自定义参数 return nmemb;}int main(){ curl_global_init(CURL_GLOBAL_ALL); // 首先全局初始化CURL CURL* curl = curl_easy_init(); // 初始化CURL句柄 if (NULL == curl) { return 0; } int my_param = 1; // 自定义一个用户参数 // 设置目标URL curl_easy_setopt(curl, CURLOPT_URL, "http://www.baidu.com"); // 设置接收到HTTP服务器的数据时调用的回调函数 curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data); // 设置自定义参数(回调函数的第四个参数) curl_easy_setopt(curl, CURLOPT_WRITEDATA, &my_param); // 执行一次URL请求 CURLcode res = curl_easy_perform(curl); // 清理干净 curl_easy_cleanup(curl); return 0;}
