从Swift 2.0调用WCF（在Azure上）失败，状态码为400

尝试调用托管在Azure上的WCF服务，失败并出现HTTP错误400. Web服务本质上充当我的Braintree（移动支付）服务器事物的一面。从Swift 2.0调用WCF（在Azure上）失败，状态码为400

下面是相关代码：发生在

let soapEnvelope = "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\"><s:Header><Action s:mustUnderstand=\"1\" xmlns=\"http://schemas.microsoft.com/ws/2005/05/addressing/none\">http://tempuri.org/IService1/GenerateToken</Action></s:Header><s:Body><GenerateToken xmlns=\"http://tempuri.org/\" /></s:Body></s:Envelope>" 

let soapEnvelopeLength = String(soapEnvelope.characters.count) 

let clientTokenURL = NSURL(string: "http://xxx.xxx.net/Service1.svc") 
let clientTokenRequest = NSMutableURLRequest(URL: clientTokenURL!) 
let session = NSURLSession.sharedSession() 

clientTokenRequest.HTTPMethod = "POST" 
clientTokenRequest.HTTPBody = soapEnvelope.dataUsingEncoding(NSUTF8StringEncoding) 

clientTokenRequest.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type") 
clientTokenRequest.addValue(soapEnvelopeLength, forHTTPHeaderField: "Content-Length") 
clientTokenRequest.addValue("http://tempuri.org/IService1/GenerateToken", forHTTPHeaderField: "soapAction") 

let task = session.dataTaskWithRequest(clientTokenRequest, completionHandler: {data, response, error -> Void in 
    print(response) 
    let clientToken = String(data: data!, encoding: NSUTF8StringEncoding) 
    let brainTree = Braintree(clientToken: clientToken!) 

    if error != nil { 
     print(error) 
     } 
    }) 
task.resume()

失败：

let task = session.dataTaskWithRequest(clientTokenRequest, completionHandler: {data, response, error -> Void in

我的SoapEnvelope几乎是从WCF测试客户端工具自动生成的XML的复制/粘贴。

我也试着用下面的SoapEnvelope，但仍得到一个400。结果clientToken保持零和B树永远不会初始化：

let soapEnvelope = "<?xml version=\"1.0\" encoding=\"utf-8\"><s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\"><s:Body><GenerateToken xmlns=\"http://tempuri.org/\" /></s:Body></s:Envelope>"

任何想法？

感谢，城邦

监测与小提琴手交通后回答我的问题，我不得不SOAP信封改为：

let soapEnvelope = "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\"><s:Body><GenerateToken xmlns=\"http://tempuri.org/\" /></s:Body></s:Envelope>"

这个工作。
