HTTP是一个客户端终端(用户)和服务器端(网站)请求和应答的标准(TCP)。通过使用Web浏览器、网络爬虫或者其它的工具,客户端发起一个HTTP请求到服务器上指定端口(默认端口为80)。我们称这个客户端为用户代理程序(user agent)。应答的服务器上存储着一些资源,比如HTML文件和图像。我们称这个应答服务器为源服务器(origin server)。在用户代理和源服务器中间可能存在多个“中间层”,比如代理服务器、网关或者隧道(tunnel)。 尽管TCP/IP协议是互联网上最流行的应用,HTTP协议中,并没有规定必须使用它或它支持的层。事实上,HTTP可以在任何互联网协议上,或其他网络上实现。HTTP假定其下层协议提供可靠的传输。因此,任何能够提供这种保证的协议都可以被其使用。因此也就是其在TCP/IP协议族使用TCP作为其传输层。 通常,由HTTP客户端发起一个请求,创建一个到服务器指定端口(默认是80端口)的TCP连接。HTTP服务器则在那个端口监听客户端的请求。一旦收到请求,服务器会向客户端返回一个状态,比如"HTTP/1.1 200 OK",以及返回的内容,如请求的文件、错误消息、或者其它信息。 所有HTTP响应的第一行都是状态行,依次是当前HTTP版本号,3位数字组成的状态代码,以及描述状态的短语,彼此由空格分隔。 状态代码的第一个数字代表当前响应的类型: 1xx消息——请求已被服务器接收,继续处理 2xx成功——请求已成功被服务器接收、理解、并接受 3xx重定向——需要后续操作才能完成这一请求 4xx请求错误——请求含有词法错误或者无法被执行 5xx服务器错误——服务器在处理某个正确请求时发生错误
