使用 PHP 和 cURL 访问 Exchange Web 服务
您好,
我目前正在编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。
经过几天的搜索,我已经能够通过 PHP 的 Soap 客户端和自定义 HTTPS Stream 包装器连接到 EWS。 这个网站在这一点上对我帮助很大。
使用 XAMPP 在我的 Windows 7 机器上一切正常
现在我将我的项目上传到 Debian 6.0 Squeeze 开发机器,该机器在 Web 服务器、php 设置、mysql 设置等方面与我的 Windows 机器具有完全相同的配置,但它无法工作 debian 机器可以毫无问题
地解析并 ping 交换服务器
我将实际问题归结为 cURL 无法检索 EWS 的 WSDL 文件
它总是收到空响应和401(未经授权)状态代码
我使用的凭据是正确的,相同的凭据在我的 Windows 计算机上工作
我提取了错误的代码并尝试独立运行它,它看起来像这样:
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( $curl );
我在这里收到的结果是提到的 401状态码和空响应 当我在浏览器中调用相同的 url 或在 Windows 计算机上使用相同的代码时,我得到了我想要的 WSDL 文件
实际上我什至无法判断这是一个基于 Linux 的问题还是我在某个时候做错了什么,我已经为此苦苦挣扎了两天。
有人可以找到我的错误或告诉我它不起作用的原因吗?
我可以根据需要提供任何进一步需要的信息
Hello,
I am currently writing a client to access a Microsoft Exchange server and read contacts, appointments etc. from it.
Through days of searching I've been able to connect to the EWS via PHP's Soap client and a custom HTTPS Stream wrapper. This website helped me greatly at this point.
Everything worked fine on my Windows 7 machine using XAMPP
Now I uploaded my project to a Debian 6.0 Squeeze development machine that has exactly the same configuration as my Windows machine regarding the web-server, php settings, mysql settings etc. but it just wont work anymore
The debian machine can resolve and ping the exchange server without problems
I nailed the actual problem down to a point, where cURL isn't able to retrieve the WSDL file of the EWS
It always receives an empty response and a 401 (Unauthorized) status code
The credentials I use are correct, the same credentials work on my windows machine
I extracted the faulty piece of code and tried running it stand-alone, it looks like this:
echo "Trying to get https://".$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

如果您正确初始化您的肥皂客户端,您应该能够以这种方式执行任何请求:
对于您的代码,请尝试注释掉以下行:
另请参阅此包装器在您的设置中工作的位置:
http://ewswrapper.lafiel.net/
如果是这样,请查看那里使用的 SOAP 类 - 它使用内置的 php 作为基础。
为什么你不能在本地存储 wsdl 文件?
更新:
好吧,我在我的 Debian 盒子里尝试过这个,这对我来说完美无缺:

If you initialize your soap client properly, you should be able to preform any requests requests this way:
As to your code, try commenting out following line:
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:

您的第一次检查不应使用任何复杂的脚本。
相反,请尝试从 Debian 计算机上的简单浏览器窗口打开 WDSL,如下所示:
https://your.exchange-server.com/EWS/Services.wsdl
如果这不起作用,可能存在取决于客户端 IP 或客户端网络的访问限制(例如,您的开发计算机位于受信任的网络中,而您的 Debian 则不是)。事实上,您收到 401(“未经授权”- 请求需要用户身份验证)表明联系服务器没有问题,但身份验证没有问题。
我建议您进行的另一项检查是查看您的 phpinfo() 以确保您在 Debian 上安装的 PHP 能够处理 HTTP*S* 请求。确保已安装 OpenSSL!
Your first check should not use any complex scripting.
Instead try opening the WDSL from a simple browser window on the Debian machine like so:
https://your.exchange-server.com/EWS/Services.wsdl
If that does not work there are probably access restrictions in place that depend on the client IP or client network (e.g. your development machine being in a trusted network, your Debian not). The fact that you get a 401 ("Unauthorized" - request requires user authentication) suggests that there is no problem with contacting the server but with authentication.
Another check I suggest is that you have a look into your phpinfo() to make sure your PHP installation on Debian is capable of handling HTTP*S* requests. Make sure, OpenSSL is installed!
这篇文章帮助我指明了正确的方向。要记住的一件事是
您的 PHP 安装可能不共享系统的 cURL / libcurl 设置。

This article helped point me in the right direction. One thing to keep in mind is that
your PHP installation may not be sharing your system's cURL / libcurl setup.
