使用PHP和cURL访问Exchange Web服务 [英] Access Exchange Web Services with PHP and cURL
问题描述
您好，
我目前正在写一个客户端来访问Microsoft Exchange服务器，并从中读取联系人，约会等。
通过搜索天，我已经能够通过PHP的Soap客户端和一个自定义的HTTPS流包装器连接到EWS。 这个网站在这一点上帮助了我很大。 / p>
在我使用XAMPP的Windows 7机器上一切正常工作
现在我将项目上传到Debian 6.0 Squeeze开发机器有与我的Windows机器完全相同的配置关于网络服务器，php设置，mysql设置等，但它只是不再工作
debian机器可以解决并且没有问题地ping交换服务器
我将实际问题锁定到某一点，其中cURL无法检索EWS的WSDL文件
它总是收到一个空响应和401（未授权）状态码
我使用的凭证是正确的，在我的Windows机器上工作
我提取了错误的代码段，并尝试独立运行它，它看起来像这样：
echo尝试获取https：//。$ cfg ['Exchange.Server']。/ EWS / Services.wsdl< br>;
$ curl = curl_init（'https：//'.$cfg ['Exchange.Server']。'/ EWS / Services.wsdl'）;
curl_setopt（$ curl，CURLOPT_RETURNTRANSFER，true）;
curl_setopt（$ curl，CURLOPT_HTTP_VERSION，CURL_HTTP_VERSION_1_1）;
curl_setopt（$ curl，CURLOPT_HTTPAUTH，CURLAUTH_NTLM）;
curl_setopt（$ curl，CURLOPT_USERPWD，$ cfg ['Exchange.User']。'：'。$ cfg ['Exchange.Password']）;
curl_setopt（$ curl，CURLOPT_SSL_VERIFYPEER，false）;
curl_setopt（$ curl，CURLOPT_SSL_VERIFYHOST，false）;
echo'< pre>';
$ response = curl_exec（$ curl）;
$ info = curl_getinfo（$ curl）;
var_dump（$ info）;
var_dump（$ response）;
curl_close（$ curl）;
我收到的结果是提到的401状态码和空响应
当我在我的浏览器中调用相同的URL或在我的Windows机器上使用相同的代码，我得到我想要的WSDL文件
其实我甚至不知道这是一个基于linux的问题，或者如果我在某些时候做错了，我现在正在努力工作2天。
有人可能找到我的
我可以根据需要提供任何进一步需要的信息
如果你正确地初始化你的soap客户端，你应该可以这样预制任何请求请求：
$ curl = curl_init（$ location）; //'https://'.$server_address.'/EWS/Exchange.asmx'
curl_setopt（$ ch，CURLOPT_SSL_VERIFYPEER，false）;
curl_setopt（$ ch，CURLOPT_SSL_VERIFYHOST，false）;
curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）;
curl_setopt（$ ch，CURLOPT_HTTPHEADER，$ headers）; // valid soap headers with keep-alive
curl_setopt（$ ch，CURLOPT_POST，true）;
curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ request）;
curl_setopt（$ ch，CURLOPT_HTTP_VERSION，CURL_HTTP_VERSION_1_1）;
curl_setopt（$ ch，CURLOPT_USERPWD，$ user。'：'。$ password）;
$ response = curl_exec（$ curl）;
至于您的代码，请尝试注释以下行：
curl_setopt（$ curl，CURLOPT_HTTPAUTH，CURLAUTH_NTLM）;
还要看看这个包装器在你的设置上的工作：
http://ewswrapper.lafiel.net/
如果是这样，看看那里使用的SOAP类 - 它使用php内置为
为什么你不能在本地存储wsdl文件？
$ b b
UPDATE：
好吧，我在我的Debian框中玩了这个，这对我完美无缺：
$ domain ='xxxxxx';
$ user ='xxxxxx';
$ password ='xxxxxx';
$ ch = curl_init（'https：//'.$domain.'/EWS/Services.wsdl'）;
curl_setopt（$ ch，CURLOPT_SSL_VERIFYPEER，false）;
curl_setopt（$ ch，CURLOPT_SSL_VERIFYHOST，false）;
curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）;
curl_setopt（$ ch，CURLOPT_HEADER，0）;
curl_setopt（$ ch，CURLOPT_HTTP_VERSION，CURL_HTTP_VERSION_1_1）;
curl_setopt（$ ch，CURLOPT_USERPWD，$ user。'：'。$ password）;
$ response = curl_exec（$ ch）;
$ info = curl_getinfo（$ ch）;
$ error = curl_error（$ ch）;
print_r（array（$ response，$ info，$ error））;
返回

Hello,
I am currently writing a client to access a Microsoft Exchange server and read contacts, appointments etc. from it.
Through days of searching I've been able to connect to the EWS via PHP's Soap client and a custom HTTPS Stream wrapper. This website helped me greatly at this point.
Everything worked fine on my Windows 7 machine using XAMPP
Now I uploaded my project to a Debian 6.0 Squeeze development machine that has exactly the same configuration as my Windows machine regarding the web-server, php settings, mysql settings etc. but it just wont work anymore
The debian machine can resolve and ping the exchange server without problems
I nailed the actual problem down to a point, where cURL isn't able to retrieve the WSDL file of the EWS
It always receives an empty response and a 401 (Unauthorized) status code
The credentials I use are correct, the same credentials work on my windows machine
I extracted the faulty piece of code and tried running it stand-alone, it looks like this:
echo "Trying to get https://".$cfg[ 'Exchange.Server' ]."/EWS/Services.wsdl<br>";
$curl = curl_init( 'https://'.$cfg[ 'Exchange.Server' ].'/EWS/Services.wsdl' );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1 );
curl_setopt( $curl, CURLOPT_HTTPAUTH, CURLAUTH_NTLM );
curl_setopt( $curl, CURLOPT_USERPWD, $cfg[ 'Exchange.User' ].':'.$cfg[ 'Exchange.Password' ] );
curl_setopt( $curl, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $curl, CURLOPT_SSL_VERIFYHOST, false );
echo '<pre>';
$response = curl_exec( $curl );
$info = curl_getinfo( $curl );
var_dump( $info );
var_dump( $response );
curl_close( $curl );
The result I receive here is the mentioned 401 status code and an empty response When I call the same url in my browser or with the same code on my windows machine, I get the WSDL file I want
Actually I can't even tell if this is a linux-based problem or if I do something wrong at some point, I'm struggling with this for 2 days now.
Is there someone that may be able to find my mistake or tell me the reason why it doesn't work?
I may provide any further needed information on demand
If you initialize your soap client properly, you should be able to preform any requests requests this way:
$curl = curl_init($location); //'https://'.$server_address.'/EWS/Exchange.asmx'
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); //valid soap headers with keep-alive
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_USERPWD, $user.':'.$password);
$response = curl_exec($curl);
As to your code, try commenting out following line:
curl_setopt( $curl, CURLOPT_HTTPAUTH, CURLAUTH_NTLM );
Also take a look wherever this wrapper works on your setup: http://ewswrapper.lafiel.net/ If it does, take a look at SOAP classes used there - it uses php built-in as base.
Why can't you store wsdl file locally anyways?
UPDATE:
Ok, I played around with this in my Debian box and this works for me flawlessly:
$domain = 'xxxxxx';
$user = 'xxxxxx';
$password = 'xxxxxx';
$ch = curl_init('https://'.$domain.'/EWS/Services.wsdl');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_USERPWD, $user.':'.$password);
$response = curl_exec($ch);
$info = curl_getinfo( $ch );
$error = curl_error ($ch);
print_r(array($response,$info,$error));
returns
