我正在發送請求與請求正文中的某個參數。使用NSURLConnection發送POST請求
這裏是iOS的代碼：
NSURL *url = [NSURL URLWithString:purchaseURL];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSString *requestString = [NSString stringWithString:@"userid=1&couponid=1&Ccnum=7b6cd9a44365752cf39c1edf97890b72&Cctype=Visa&Cvv=434&Billingfirstname=Ankit&Billinglastname=Ankit&Street=some&getCity=mycity&State=mystate&getZip=54355&Ccexpmonth=5&Ccexpyear=2012&Phone=43423342"];
NSMutableData *postData=[NSMutableData data];
[postData appendData:[requestString dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPMethod:@"POST"];
[request setValue:[NSString stringWithFormat:@"%d", [postData length]] forHTTPHeaderField:@"Content-Length"];
[request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
NSLog(@"content length %d",[postData length]);
[request setValue:@"text/html" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSLog(@"purchage url string %@",postData);
connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
NSAssert(self.connection != nil, @"Failure to create URL connection.");
這是PHP文件，將處理後的請求。它處理輸入並且響應採用JSON格式。
public function restpurchaseAction(Request $request)
{
$userid = $_POST['userid'];
$couponid = $POST['couponid'];
//Check that email was verified
//Get the user object to compare id to the listed deals id
if(!$user->getEmailVerified())
{

}

$user = $repository->findOneByUsername($userid);

我無法找到錯誤或代碼中的任何問題。我也嘗試了ASIHttpRequest/ASIFormDataRequest，但無法讓它工作。我在調用Web服務的方式有問題嗎？
歡迎來到SO - 您的問題，因爲它目前的立場是不容易回答，因爲你正在張貼的PHP代碼續牆發現了很多不相關的東西。您也不會告訴我們發佈數據的結果。你有沒有試圖簡單地在服務器端登錄整篇文章來查看收到的內容？您是否嘗試過使用代理（例如Charles）來監控設備和服務器之間的通信？ – Till 2012-01-02 12:46:03
我不確定，但嘗試使用NSASCIIStringEncoding替換NSUTF8StringEncoding ... – 2012-01-02 12:50:39
**等待！**您直接在其單個POST請求中發送信用卡號碼及其CCV和失效日期？它可能不符合PCI DSS標準。 – Raptor 2013-05-24 04:09:12
