    栏目:Linux/apache问题 时间:2019-10-16 09:30

    示例代码1: 用file_get_contents 以get方式获取内容
    复制代码 代码如下:
    <?php
    $url='http://www.baidu.com/';
    $html=file_get_contents($url);
    //print_r($http_response_header);
    ec($html);
    printhr();
    printarr($http_response_header);
    printhr();
    ?>


    示例代码2: 用fopen打开url, 以get方式获取内容
    复制代码 代码如下:
    <?
    $fp=fopen($url,'r');
    printarr(stream_get_meta_data($fp));
    printhr();
    while(!feof($fp)){
    $result.=fgets($fp,1024);
    }
    echo"url body: $result";
    printhr();
    fclose($fp);
    ?>

    示例代码3:用file_get_contents函数,以post方式获取url
    复制代码 代码如下:
    <?php
    $data=array('foo'=>'bar');
    $data=http_build_query($data);

    $opts=array(
    'http'=>array(
    'method'=>'POST',
    'header'=>"Content-type: application/x-www-form-urlencoded\r\n".
    "Content-Length: ".strlen($data)."\r\n",
    'content'=>$data
    ),
    );
    $context=stream_context_create($opts);
    $html=file_get_contents('http://localhost/e/admin/test.html',false,$context);
    echo$html;
    ?>

    示例代码4:用fsockopen函数打开url,以get方式获取完整的数据,包括header和body
    复制代码 代码如下:
    <?
    functionget_url($url,$cookie=false){
    $url=parse_url($url);
    $query=$url[path]."?".$url[query];
    ec("Query:".$query);
    $fp=fsockopen($url[host],$url[port]?$url[port]:80,$errno,$errstr,30);
    if(!$fp){
    returnfalse;
    }else{
    $request="GET$queryHTTP/1.1\r\n";
    $request.="Host:$url[host]\r\n";
    $request.="Connection: Close\r\n";
    if($cookie)$request.="Cookie: $cookie\n";
    $request.="\r\n";
    fwrite($fp,$request);
    while(!@feof($fp)){
    $result.=@fgets($fp,1024);
    }
    fclose($fp);
    return$result;
    }
    }
    //获取url的html部分,去掉header
    functionGetUrlHTML($url,$cookie=false){
    $rowdata=get_url($url,$cookie);
    if($rowdata)
    {
    $body=stristr($rowdata,"\r\n\r\n");
    $body=substr($body,4,strlen($body));
    return$body;
    }
    returnfalse;
    }
    ?>

    示例代码5:用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body
    复制代码 代码如下:
    <?
    functionHTTP_Post($URL,$data,$cookie,$referrer=""){
    // parsing the given URL
    $URL_Info=parse_url($URL);

    // Building referrer
    if($referrer=="")// if not given use this script. as referrer
    $referrer="111";

    // making string from $data
    foreach($dataas$key=>$value)
    $values[]="$key=".urlencode($value);
    $data_string=implode("&",$values);

    // Find out which port is needed - if not given use standard (=80)
    if(!isset($URL_Info["port"]))
    $URL_Info["port"]=80;

    // building POST-request:
    $request.="POST ".$URL_Info["path"]." HTTP/1.1\n";
    $request.="Host: ".$URL_Info["host"]."\n";
    $request.="Referer:$referer\n";
    $request.="Content-type: application/x-www-form-urlencoded\n";
    $request.="Content-length: ".strlen($data_string)."\n";
    $request.="Connection: close\n";
