在PHP中,iPhone POST请求始终被$_SERVER [‘REQUEST_METHOD’]视

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上尝试它也是如此.

我的POST请求如下(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,那里有很多虚拟文本,通常不会出现在iPhone上,但是我试图通过html表单进行相同的调用,这很有效.因此,我已经复制了所有信息,看看这是否有所作为,但无济于事.

我比较了两个请求(一个来自iPhone,另一个来自我的php页面),它们看起来完全一样.

我大吃一惊 – 有没有人对如何做有很好的建议？

编辑：

Your test isn’t testing for post or post vs get,it is testing for POST specifically,you could have a case issue there… Have you tried inspecting the request itself in php? – Grady Player

是的,这可能是真的,但该行总是返回GET,因此案例问题已经涵盖,如果这就是你的意思.

Also,please post the result of print_r($_SERVER) from the server when the iPhone sends the request – Aleks G

Did you try checking to see if a known variable,e.g. $_POST[‘known_to_be_set_by_client’] is set or not? It’s not PHP that figures out if a request is POST or GET,it’s the web server. – Tim Post

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.当我从表格中回应同样的东西时就在那里.

Post the iOS code your using to make the actual request. – Cliff Ribaudo
