00 一个简单的HttpServer

Mon, 09 Jul 2012 14:10:00 GMT

本周开始，开发一个简单的HttpServer�Q�欢�q�大家指正�?

中间借鉴了一些网友的代码�Q�在此致谢，参见如下�Q?br />
/**
* 一个简单的�?Java Socket �~�写�?HTTP 服务器应�? 演示了请求和应答的协议通信内容以及 �l�客��L��q�回 HTML 文本和二�q�制数据文�g(一个图�?, 同时展示�?404, 200 �{�状态码.
* 首先�q�行�q�个�E�序,然后打开Web��览�?键入http://localhost,则这个程序能够显�C�出��览器发送了那些信息 �q�且向浏览器�q�回一个网��和一副图�? �q�测试同��览器对�? 当浏览器看到 HTML 中带有图片地址�?

* �q�接到已有的服务器则可以帮忙理解��览器的�q�行�q�程和服务器端的�q�回内容.
*
*


 *       当用户在Web���览器地址栏中输入一个带有http://前缀的URL�q�按下Enter�?或者在Web��面中某个以http://开头的���链接上单击鼠标,HTTP事务处理的第一个阶�D?-建立�q�接阶段���开始了.HTTP的默认端口是80.
 *    随着�q�接的徏�?HTTP���p��入了客户向服务器发送请求的阶段.客户向服务器发送的��h��是一个有特定格式的ASCII消息,其语法规则�ؓ:
 * < Method > < URL > < HTTP Version > <\n>
 * { : <\n>}*
 * <\n>
 * { Entity Body }
 *    ��h��消息的顶端是��h���?用于指定�Ҏ��,URL和HTTP协议的版�?��h��行的最后是回�R换行.�Ҏ��有GET,POST,HEAD,PUT,DELETE�{?
 * 在请求行之后是若�q�个报头(Header)�?每个报头行都是由一个报头和一个取值构成的二元�?报头和取��g��间以":"分隔;报头行的最后是回�R换行.常见的报头有Accept(指定MIME媒体�c�d��),Accept_Charset(响应消息的编码方�?,Accept_Encoding(响应消息的字�W�集),User_Agent(用户的浏览器信息)�{?
 *    在请求消息的报头行之后是一个回车换�?表明��h��消息的报头部分结�?在这个\n之后是请求消息的消息实体(Entity Body).具体的例子参看httpRequest.txt.
 *     Web服务器在收到客户��h���q�作出处理之�?要向客户发送应�{�消�?与请求消息一�?应答消息的语法规则�ؓ:
 * < HTTP Version>  []<\n>
 * { : <\n> } *
 * <\n>
 * { Entity Body }
 *    应答消息的第一行�ؓ状态行,其中包括了HTTP版本�?状态码和对状态码�q�行���短解释的消息;状态行的最后是回�R换行.状态码�?位数字组�?�?�c? 
 * 参看:HTTP应答码及其意�?
 * 
 * 1XX 保留 
 * 2XX 表示成功 
 * 3XX 表示URL已经被移�?
 * 4XX 表示客户错误 
 * 5XX 表示服务器错�?
 * 例如:415,表示不支持改媒体�c�d��;503,表示服务器不能访�?最常见的是200,表示成功.常见的报头有:Last_Modified(最后修�Ҏ���?,Content_Type(消息内容的MIME�c�d��),Content_Length(内容长度)�{?
