我正在发送请求与请求正文中的某个参数。使用NSURLConnection发送POST请求
这里是iOS的代码：
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.");
这是PHP文件，将处理后的请求。它处理输入并且响应采用JSON格式。
public function restpurchaseAction(Request $request)

$userid = $_POST['userid'];

我无法找到错误或代码中的任何问题。我也尝试了ASIHttpRequest/ASIFormDataRequest，但无法让它工作。我在调用Web服务的方式有问题吗？
欢迎来到SO - 您的问题，因为它目前的立场是不容易回答，因为你正在张贴的PHP代码续墙发现了很多不相关的东西。您也不会告诉我们发布数据的结果。你有没有试图简单地在服务器端登录整篇文章来查看收到的内容？您是否尝试过使用代理（例如Charles）来监控设备和服务器之间的通信？ – Till 2012-01-02 12:46:03
我不确定，但尝试使用NSASCIIStringEncoding替换NSUTF8StringEncoding ... – 2012-01-02 12:50:39
**等待！**您直接在其单个POST请求中发送信用卡号码及其CCV和失效日期？它可能不符合PCI DSS标准。 – Raptor 2013-05-24 04:09:12
