key url

类名 :HttpRequest($url="",$method="GET",$useSocket=0)
//$url为请求的地址;默认请求方法为GET;$useSocket默认为0,使用fsockopen方法,如果设置为1则使用socket_create方法

方法:
open($ip="",$port=-1) //打开同服务器的连接,默认不用设置这两个参数(一个同事在linux用的时候,请求的不是hostname解析的IP,因此加了这两个参数,以连接真实的服务器IP)
setTimeout($timeout=0) //设置获取数据的超时时间,必须在send方法调用之前设置才有效,单位秒,默认值0为不限制
setRequestHeader($key,$value="") //设置请求头,必须在send方法调用之前设置才有效
removeRequestHeader($key,$value="") //移除指定键值的请求头,必须在send方法调用之前调用才有效
send($data="") //发送数据$data到服务器
getResponseBody() //获取服务器返回的文本
getAllResponseHeaders() //获取服务器响应的所有头信息
getResponseHeader($key) //获取服务器响应的某个头信息,例如Server,Set_Cookie等

属性:
$url //要请求的url
$method //请求方法(POST/GET)
$port //请求的端口
$hostname //请求的主机名
$uri //url的文件部分
$protocol //请求协议(http)(包括本属性的以上5个属性均由程序自动通过url分析)
$excption //异常信息
$_headers=array() //请求头array("key"=>"value")
$_senddata //发送到服务器的数据
$status //返回的状态码
$statusText //状态信息
$HttpProtocolVersion //服务器的HTTP协议版本

注意:
Host头由程序自动设置,当用POST方法请求时,Content-Length和Content-Type已被自动设置。
支持gzip压缩的页面
