php curl：我如何模拟一个获取请求完全像一个web浏览器？ [英] php curl: how can i emulate a get request exactly like a web browser?

问题描述

有网站，当我打开特定的ajax请求浏览器，我得到的结果页面，但是当我尝试加载它们与curl，我收到一个错误从服务器。

$ b $

这是我在做什么：

$ b $ p b

  $ url =https://new.aol.com/productsweb/subflows/ScreenNameFlow/AjaxSNAction.do?s=username&f=firstname&l = lastname; 
 ini_set（'user_agent'，'Mozilla / 4.0（compatible; MSIE 6.0; Windows NT 
 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322）'）; 
 $ ch = curl_init（）; 
 
 curl_setopt（$ ch，CURLOPT_URL，$ url）; 
 $ result = curl_exec（$ ch）; 
 print $ result; 
  

解决方案

您确定curl模块的荣誉ini_set（'user_agent '，...）？有一个选项CURLOPT_USERAGENT在 http://docs.php.net/function.curl-setopt 。

是否还有服务器测试的Cookie？您可以使用CURLOPT_COOKIE，CURLOPT_COOKIEFILE和/或CURLOPT_COOKIEJAR来处理。

编辑：由于请求使用https，因此在验证证书时可能会出错，请参阅CURLOPT_SSL_VERIFYPEER。 / p>

  $ url =https://new.aol.com/productsweb/subflows/ScreenNameFlow/AjaxSNAction.do?s=username& ; f = firstname& l = lastname; 
 $ agent ='Mozilla / 4.0（compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322）'; 
 
 $ ch = curl_init（）; 
 curl_setopt（$ ch，CURLOPT_SSL_VERIFYPEER，false）; 
 curl_setopt（$ ch，CURLOPT_VERBOSE，true）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; 
 curl_setopt（$ ch，CURLOPT_USERAGENT，$ agent）; 
 curl_setopt（$ ch，CURLOPT_URL，$ url）; 
 $ result = curl_exec（$ ch）; 
 var_dump（$ result）; 
  

there are websites that when i open specific ajax request on browser i get the resulted page, but when i try to load them with curl, i receive an error from the server.

how can i properly emulate a get request to the server that will simulate a browser ?

that's what i'm doing:

$url="https://new.aol.com/productsweb/subflows/ScreenNameFlow/AjaxSNAction.do?s=username&f=firstname&l=lastname";
ini_set('user_agent', 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT
5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)');
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
print $result;

解决方案

Are you sure the curl module honors ini_set('user_agent',...)? There is an option CURLOPT_USERAGENT described at http://docs.php.net/function.curl-setopt.
Could there also be a cookie tested by the server? That you can handle by using CURLOPT_COOKIE, CURLOPT_COOKIEFILE and/or CURLOPT_COOKIEJAR.

edit: Since the request uses https there might also be error in verifying the certificate, see CURLOPT_SSL_VERIFYPEER.

$url="https://new.aol.com/productsweb/subflows/ScreenNameFlow/AjaxSNAction.do?s=username&f=firstname&l=lastname";
$agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
var_dump($result);
