Java之使用socket连接http接口

• 代码
• 总结
• 参考

    public static void execute() throws IOException {
        StringBuffer requestMessage = new StringBuffer();
        requestMessage.append("GET /add2 HTTP/1.1rn");
        requestMessage.append("cache-control: no-cachern");
        requestMessage.append("Accept: */*rn");
        requestMessage.append("Host: 127.0.0.1:8080rn");
        requestMessage.append("Connection: keep-alivern");
        
        Socket client = new Socket();
        InetSocketAddress inetSocketAddress = new InetSocketAddress("127.0.0.1", 8080);
        client.connect(inetSocketAddress, 1000);
        PrintWriter pWriter = new PrintWriter(client.getOutputStream(),true);
        pWriter.println(requestMessage.toString());
        client.close();
    }

http接口使用的springboot

 @GetMapping("/add2")
    public String addUser(){
        System.out.println("小明");
        return "success";
    }

http协议是基于tcp的,当tcp中的数据具有某些特定的格式的时候,就能称之为http协议:比如上文的往socket中写入的数据的第一行: GET /add2 HTTP/1.1
而http协议进行解析时,会对固定格式的数据进行解析,比如:/add2,就会映射到 Controller中的 @GetMapping("/add2")上(框架自动处理好的)
