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: <?php class httprequest{ public $url,$method,$port,$hostname,$uri,$protocol,$excption,$_headers=array(),$_senddata,$status,$statustext,$httpprotocolversion; private $fp=0,$_buffer="",$responsebody,$responseheader,$timeout=0,$usesocket; //构造函数 function __construct($url="",$method="get",$usesocket=0){ $this->url = $url; $this->method = strtoupper($method); $this->usesocket = $usesocket; $this->setrequestheader("accept","*/*"); $this->setrequestheader("accept-language","zh-cn"); $this->setrequestheader("accept-encoding","gzip, deflate"); $this->setrequestheader("user-agent","httprequest class 1.0"); //可调用setrequestheader来修改 } //连接服务器 public function open($ip="",$port=-1){ if(!$this->_geturlinfo()) return false; $this->setrequestheader("host",$this->hostname); $this->setrequestheader("connection","close"); $ip = ($ip=="" ? $this->hostname : $ip); $port = ($port==-1 ? $this->port : $port); if($this->usesocket==1){ if(!$this->fp=$socket=socket_create(af_inet,sock_stream,0)) { $this->excption="can not create socket";return false; }else{ if(!socket_connect($this->fp,$ip, $port) ){ $this->excption="can not connect to server " . $this->hostname .
