Http 学习笔记（一）

介绍　　

　　HTTP协议是Hyper Text Transfer Protocol（超文本传输协议）的缩写,是用于从万维网（WWW:World Wide Web ）服务器传输超文本到本地浏览器的传送协议。。 HTTP是一个基于TCP/IP通信协议来传递数据（HTML 文件, 图片文件, 查询结果等）。

 

一、服务端和客户端如何设置和获取状态码

PHP服务端如何设置返回状态码

/**
     * HTTP Protocol defined status codes
     * HTTP协议状态码,调用函数时候只需要将$num赋予一个下表中的已知值就直接会返回状态了。
     * @param int $num
     */
    public function https($num) {
        $http = array (
            100 => "HTTP/1.1 100 Continue",
            101 => "HTTP/1.1 101 Switching Protocols",
            200 => "HTTP/1.1 200 OK",
            201 => "HTTP/1.1 201 Created",
            202 => "HTTP/1.1 202 Accepted",
            203 => "HTTP/1.1 203 Non-Authoritative Information",
            204 => "HTTP/1.1 204 No Content",
            205 => "HTTP/1.1 205 Reset Content",
            206 => "HTTP/1.1 206 Partial Content",
            300 => "HTTP/1.1 300 Multiple Choices",
            301 => "HTTP/1.1 301 Moved Permanently",
            302 => "HTTP/1.1 302 Found",
            303 => "HTTP/1.1 303 See Other",
            304 => "HTTP/1.1 304 Not Modified",
            305 => "HTTP/1.1 305 Use Proxy",
            307 => "HTTP/1.1 307 Temporary Redirect",
            400 => "HTTP/1.1 400 Bad Request",
            401 => "HTTP/1.1 401 Unauthorized",
            402 => "HTTP/1.1 402 Payment Required",
            403 => "HTTP/1.1 403 Forbidden",
            404 => "HTTP/1.1 404 Not Found",
            405 => "HTTP/1.1 405 Method Not Allowed",
            406 => "HTTP/1.1 406 Not Acceptable",
            407 => "HTTP/1.1 407 Proxy Authentication Required",
            408 => "HTTP/1.1 408 Request Time-out",
            409 => "HTTP/1.1 409 Conflict",
            410 => "HTTP/1.1 410 Gone",
            411 => "HTTP/1.1 411 Length Required",
            412 => "HTTP/1.1 412 Precondition Failed",
            413 => "HTTP/1.1 413 Request Entity Too Large",
            414 => "HTTP/1.1 414 Request-URI Too Large",
            415 => "HTTP/1.1 415 Unsupported Media Type",
            416 => "HTTP/1.1 416 Requested range not satisfiable",
            417 => "HTTP/1.1 417 Expectation Failed",
            500 => "HTTP/1.1 500 Internal Server Error",
            501 => "HTTP/1.1 501 Not Implemented",
            502 => "HTTP/1.1 502 Bad Gateway",
            503 => "HTTP/1.1 503 Service Unavailable",
            504 => "HTTP/1.1 504 Gateway Time-out"
        );
        return $http[$num];
    }

使用该方法

header($this->https(300));

在谷歌浏览器查看返回的状态码
