在PHP中使用CURL访问页面: <?php $ch = curl_init('http://www.baidu.com'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 1); // 3. 执行并获取HTML文档内容 $output = curl_exec($ch); // 4. 释放curl句柄 curl_close($ch); echo $output; ?> 可以显示页面,并且可以使用curl_getinfo函数获取请求头。 但不能直观的查看,而且无法使用Fiddler进行抓包。 经过搜索后终于找到解决办法: Fiddler的抓包方式:打开Fiddler后,自动设置浏览器代理到127.0.0.1:8888。 所有浏览的网页均通过该端口进行转发,固可以抓包。 修改PHP代码: <?php $ch = curl_init('http://www.baidu.com'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch,CURLOPT_PROXY,'127.0.0.1:8888');//设置代理服务器 curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);//若PHP编译时不带openssl则需要此行 // 3. 执行并获取HTML文档内容 $output = curl_exec($ch); // 4. 释放curl句柄 curl_close($ch); echo $output; ?> 发现返回: HTTP/1.1 504 Fiddler - Receive Failure Date: Tue, 08 Oct 2013 15:22:50 GMT Content-Type: text/html; charset=UTF-8 Connection: close Timestamp: 23:22:50.647 [Fiddler] ReadResponse() failed: The server did not return a response for this request.Server returned 0 bytes. 抓包信息为: 上行 GET http://www.baidu.com HTTP/1.1 Host: www.baidu.com Accept: */* Connection: Keep-Alive 下行 HTTP/1.1 504 Fiddler - Receive Failure Date: Tue, 08 Oct 2013 15:22:50 GMT Content-Type: text/html; charset=UTF-8 Connection: close Timestamp: 23:22:50.647 [Fiddler] ReadResponse() failed: The server did not return a response for this request.Server returned 0 bytes. 经过分析后发现,请求域名,必须以“/”结尾。 更改后代码 <?php $ch = curl_init('http://www.baidu.com/'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch,CURLOPT_PROXY,'127.0.0.1:8888');//设置代理服务器 curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);//若PHP编译时不带openssl则需要此行 // 3. 执行并获取HTML文档内容 $output = curl_exec($ch); // 4. 释放curl句柄 curl_close($ch); echo $output; ?> 效果: Fiddler: 上行: GET http://www.baidu.com/ HTTP/1.1 Host: www.baidu.com Accept: */* Connection: Keep-Alive
