C++简单实现http服务端客户端传输实例

使用本代码有两个注意事项：

1.  代码使用到了httplib库，需要下载然后把.h文件放到自己的目录下  
    httplib下载地址：[https://gitcode.net/mirrors/yhirose/cpp-httplib?utm\_source=csdn\_github\_accelerator][https_gitcode.net_mirrors_yhirose_cpp-httplib_utm_source_csdn_github_accelerator]
2.  使用g++进行编译的时候要加上-lpthread参数才能正确编译成功

### 服务端代码： ###

#include <iostream>
    
    #include <chrono>
    #include <cstdio>
    #include "httplib.h"
    
    using namespace httplib;
    
    int main()
    {
        
    	Server svr;
    	if (!svr.is_valid())
    	{
        
    		printf("server has an error...\n");
    		return -1;
    	}
    
    	svr.Get("/hi", [](const Request& , Response& res)
    	{
        
    		res.set_content("Hello http!\n", "text/plain");
    	});
    
    	svr.Get("/stop",
    		[&](const Request& , Response& ) {
         svr.stop(); });
    
    	svr.listen("localhost", 1234);
    
    }

### 客户端代码： ###

#include <iostream>
    #include "httplib.h"
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
        
    	httplib::Client cli("localhost", 1234);
    	if (auto res = cli.Get("/hi"))
    	{
        
    		cout << res->status << endl;
    		cout << res->get_header_value("Content-Type") << endl;
    		cout << res->body << endl;
    	}
    	else
    	{
        
    
    	}
    	return 0;
    }

### 关于传输数据，本例中服务端只使用了“Hello http！”来代替，可以换成string类型的数据用于传输JSON等格式数据 ###
