iPhone POST 请求在 PHP 中始终被视为 GET $_SERVER['REQUEST_METHOD&

我正在iPhone上做一个项目。在这里，我必须向 Web 服务发送 POST 请求。我使用 NSMutableURLRequest 和 NSURLConnection 来发送数据，服务器使用 PHP。我发现检查if ($_SERVER['REQUEST_METHOD'] != "POST")总是失败，就像返回"GET"一样，即使我在 localhost 上尝试也是如此。

我的 POST 请求如下所示（通过 Wireshark 嗅探）：

POST tester.php HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:10.0.2) Gecko/20100101 Firefox/10.0.2
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Referer: http://localhost/tester.php
Content-Type: application/x-www-form-urlencoded
Content-Length: 422
protocol=4&msgtype=authorize&merchant=86189919&language=da&ordernumber=1274168351&amount=100&currency=DKK&continueurl=http%3A%2F%2Fquickpay.net%2Ffeatures%2Fpayment-window%2Fok.php&cancelurl=http%3A%2F%2Fquickpay.net%2Ffeatures%2Fpayment-window%2Ferror.php&callbackurl=http%3A%2F%2Fquickpay.net%2Ffeatures%2Fpayment-window%2Fcallback.php&autocapture=0&cardtypelock=&splitpayment=1&md5check=d2259d9db077e0f5a41b4bf271c3c549

当然，里面有很多虚拟文本，通常不会在iPhone上出现，但是我尝试通过html表单进行相同的调用，并且有效。因此，我复制了所有信息，看看这是否会有所作为，但无济于事。

我比较了这两个请求（一个来自iPhone，另一个来自我的php页面），它们看起来完全相同。

我很惊讶 - 有人对该怎么做有好的建议吗？

编辑：

您的测试不是针对帖子或帖子与获取进行测试，而是专门针对 POST 进行测试，您可能在那里遇到案例问题......您是否尝试过在 php 中检查请求本身？- 格雷迪·普莱尔

是的，这可能是真的，但是该行始终返回GET，因此涵盖了案例问题，如果这是您的意思。

另外，请在iPhone发送请求时从服务器发布print_r（$_SERVER）的结果 – Aleks G

您是否尝试检查是否设置了已知变量，例如 $_POST['known_to_be_set_by_client']？不是PHP可以确定请求是POST还是GET，而是Web服务器。– 蒂姆·波斯特

当我尝试从iPhone请求中回显已知变量时，它当然是空的。这是有道理的。当我从形式中呼应同样的东西时，它就在那里。

发布您用于发出实际请求的iOS代码。
