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 <span style="color: #008080;">Date</span>: 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 <span style="color: #0000ff;">return</span> a response <span style="color: #0000ff;">for</span> this request.Server returned 0 bytes. 

抓包信息为:

经过分析后发现,请求域名,必须以“/”结尾。

更改后代码

<span style="color: #000000;">php

</span><span style="color: #800080;">$ch</span> = curl_init('<span style="color: #ff0000;">http://www.baidu.com/</span>'<span style="color: #000000;">); 
curl_setopt(</span><span style="color: #800080;">$ch</span>, CURLOPT_RETURNTRANSFER, 1<span style="color: #000000;">);
curl_setopt(</span><span style="color: #800080;">$ch</span>, CURLOPT_HEADER, 1<span style="color: #000000;">);

curl_setopt(</span><span style="color: #800080;">$ch</span>,CURLOPT_PROXY,'127.0.0.1:8888');<span style="color: #008000;">//</span><span style="color: #008000;">设置代理服务器 </span>

</span><span style="color: #008000;">//</span><span style="color: #008000;"> 4. 释放curl句柄</span>
curl_close(<span style="color: #800080;">$ch</span><span style="color: #000000;">);
</span><span style="color: #0000ff;">echo</span> <span style="color: #800080;">$output</span><span style="color: #000000;">;
</span>?>

效果:

Fiddler:
