PHP中使用CURL请求页面,使用fiddler进行抓包
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
下行:
