httplib使用

server端代码

#include "httplib.h"

void deal(const Request &req, Response &res);

void deal(const Request &req, Response &res)
{
}


int main()
{    Http_server *p_http_server = (Http_server *)p_param;
    const char *p_ip = 127.0.0.1;
    int port = 8080;
    
    Server svr;
    //处理Get类型主动查询去请求
    svr.Get("/Alive_Check", [](const Request& req, Response& res) {
        //std::string content_type=req.get_header_value("Content-Type");
        std::string version=req.get_header_value("Version");
        res.status=HTTP_OK;//设置code码
        res.set_content("", "");//设置content—type
        res.set_header("Content-Length", "0");//设置content—length
        res.set_header("Version", version.c_str());//设置版本
        string buf = GMTStrFromTime();
        res.set_header("Date", buf.c_str());//设置时间
    });
    //处理Post类型主动查询去请求
    svr.Post("/Alive_Check", [&](const Request& req, Response& res) {
        //std::string content_type=req.get_header_value("Content-Type");
        std::string version=req.get_header_value("Version");
        res.status=HTTP_OK;//设置code码
        res.set_content("", "");//设置content—type
        res.set_header("Content-Length", "0");//设置content—length
        res.set_header("Version", version.c_str());//设置版
        string buf = GMTStrFromTime();
        res.set_header("Date", buf.c_str());//设置时间
    });
    //处理更新请求
    svr.Get("/update", deal);
    svr.Post("/update", deal);


    //主动关闭
    svr.Get("/stop", [&](const Request& req, Response& res) {
        svr.stop();
    });

    svr.listen(p_ip, port);
    return NULL;
}

client端

#include "httplib.h"

int main()
{
    Client cli("127.0.0.1", 8080);
    string body = "xxxxxxxxxxxxxxxxxxxxxxxx";
    Headers headers;
    headers.emplace("Host", "xxxxxxxxxxxxxxxxx");
    if(auto res = cli.Post("/statusreport", headers, body,"application/xml; charset=utf-8"))
    {
        if (res->status == HTTP_OK) 
        {
            
        }
        else
        {
            std::cout << res->status << std::endl;
        }
    } 
    else 
    {
        auto err = res.error();
        std::cout << "---------->http client error code " << err << std::endl;
    }
    cli.stop();
    return 0;
}

编译链接httplib.h就可以了，注意需要将httplib.h中的正则表达式修改成boost或者升级g++
