c++ http第一个服务
一、下载相关依赖：这是一个git开源项目 代码仓地址
二、演示代码，编译参数：g++ test.cpp -I/**** -lpthread
#include <httplib.h>
using namespace httplib;void wuhan(const Request &req, Response &res)
{printf("httplib server recv a req: %s\n ", req.path.c_str() );res.set_content("<html> \<meta http-equiv=\"Content-Type\" content=\"text/html;charset=utf-8\"> \<h1> 武汉, 加油！</h1></html>","text/html");res.status = 200;
}int main(void)
{using namespace httplib;Server svr;svr.set_base_dir("./");/// Get
svr.Get("/wuhan", wuhan);svr.Get("/hi", [](const Request& req, Response& res) {res.set_content("Hello World!", "text/plain");});svr.Get(R"(/numbers/(\d+))", [&](const Request& req, Response& res) {auto numbers = req.matches[1];res.set_content(numbers, "text/plain");});svr.Get("/body-header-param", [](const Request& req, Response& res) {if (req.has_header("Content-Length")) {auto val = req.get_header_value("Content-Length");}if (req.has_param("key")) {auto val = req.get_param_value("key");}res.set_content(req.body, "text/plain");});svr.Get("/stop", [&](const Request& req, Response& res) {svr.stop();});/// listensvr.listen("localhost", 1234);
}三、访问网址http://localhost:1234/hi
