php 仿asp xmlhttprequest请求数据代码
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,inc.http.php文件代码如下:
