在Swift中为SOAP POST从NSURLConnection移动到NSURLSession

我正在尝试从NSURLConnection转移到NSURLSession以获得一篇SOAP文章，但似乎在NSURLSessionDataDelegate方面存在问题

以下是NSURLConnection中运行良好的旧代码：

let soapMessage = "<?xml version='1.0' encoding='UTF-8'?><SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/' xmlns:ns1='http://tempuri.org/'><SOAP-ENV:Body><ns1:get_Countries/></SOAP-ENV:Body></SOAP-ENV:Envelope>"
    print("Soap Packet is \(soapMessage)")

    let urlString = "https://example.com/Service.svc"
    let url = NSURL(string: urlString)
    let theRequest = NSMutableURLRequest(URL: url!)
    let msgLength = String(soapMessage.characters.count)

    theRequest.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
    theRequest.addValue(msgLength, forHTTPHeaderField: "Content-Length")
    theRequest.addValue("http://tempuri.org/IService/get_Countries", forHTTPHeaderField: "SoapAction")
    theRequest.HTTPMethod = "POST"
    theRequest.HTTPBody = soapMessage.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
    print("Request is \(theRequest.allHTTPHeaderFields!)")

    let connection = NSURLConnection(request: theRequest, delegate: self, startImmediately: false)
    connection?.start()

因此，这些代码都可以正常工作，仅供参考，以便您可以看到我在过去所做的工作，以及API实际工作的事实！但是，如果转而使用NSURLSession和NSURLSessionDataDelegate，则无法使其正常工作

下面是新代码：

let soapMessage = "<?xml version='1.0' encoding='UTF-8'?><SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/' xmlns:ns1='http://tempuri.org/'><SOAP-ENV:Body><ns1:get_Countries/></SOAP-ENV:Body></SOAP-ENV:Envelope>"
    print("Soap Packet is \(soapMessage)")

    let urlString = "https://example.com/Service.svc"
    let url = NSURL(string: urlString)
    let theRequest = NSMutableURLRequest(URL: url!)
    let msgLength = String(soapMessage.characters.count)

    theRequest.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
    theRequest.addValue(msgLength, forHTTPHeaderField: "Content-Length")
    theRequest.addValue("http://tempuri.org/IService/get_Countries", forHTTPHeaderField: "SoapAction")
    theRequest.HTTPMethod = "POST"
    theRequest.HTTPBody = soapMessage.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
    print("Request is \(theRequest.allHTTPHeaderFields!)")

let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration:config, delegate: self, delegateQueue: NSOperationQueue.mainQueue())
let task = session.dataTaskWithRequest(theRequest)
task.resume()

因此，当我运行代码时，我会得到输出：

“上午在NSURLSessionLegate didReceiveChallenge” “是的，授权”

因此，它将进入didReceiveChallenge罚款，它似乎授权HTTPS安全证书罚款，但没有进一步发生，它没有做任何其他事情，我希望它进入didReceiveResponse，然后进入didReceiveData，但没有进一步发生

所以我被卡住了，我当然可以继续使用NSURLConnection，因为它一切正常，但我想了解NSURLConnection，特别是我出了什么问题。如果有人能帮上忙，那就太好了

谢谢

如果其他人也有同样的问题，我会解决的。问题是我没有在didReceiveChallenge和didReceiveResponse委托中使用completionHandler

func URLSession(session: NSURLSession, dataTask: NSURLSessionDataTask, didReceiveResponse response: NSURLResponse, completionHandler: (NSURLSessionResponseDisposition) -> Void) {

completionHandler（NSURLSessionResponseDisposition.Allow）//.Cancel，如果要停止下载

}

如果你能算出答案，你能把它贴出来吗？我也确实需要帮助。

func URLSession(session: NSURLSession, didReceiveChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?) -> Void) {

    print("Am in NSURLSessionDelegate didReceiveChallenge")

    if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust && challenge.protectionSpace.host == "example.com" {
        NSLog("yep authorised")
        let credential = NSURLCredential(trust: challenge.protectionSpace.serverTrust!)
        challenge.sender!.useCredential(credential, forAuthenticationChallenge: challenge)
    } else {
        NSLog("nope")
        challenge.sender!.performDefaultHandlingForAuthenticationChallenge!(challenge)
    }

}
func URLSessionDidFinishEventsForBackgroundURLSession(session: NSURLSession) {
    print("Am in URLSessionDidFinishEventsForBackgroundURLSession")
    let xmlParser = NSXMLParser(data: MutableData)
    xmlParser.delegate = self
    xmlParser.parse()
    xmlParser.shouldResolveExternalEntities = true
}
func URLSession(session: NSURLSession, didBecomeInvalidWithError error: NSError?) {
    print("error of \(error)")
}

func URLSession(session: NSURLSession, dataTask: NSURLSessionDataTask, didReceiveResponse response: NSURLResponse, completionHandler: (NSURLSessionResponseDisposition) -> Void) {
    print("Am in didReceiveResponse")
    MutableData.length = 0
}


func URLSession(session: NSURLSession, dataTask: NSURLSessionDataTask, didReceiveData data: NSData) {
    print("Am in didReceiveData")
    MutableData.appendData(data)
}

func URLSession(session: NSURLSession, task: NSURLSessionTask, didCompleteWithError error: NSError?) {
    print("error of \(error)")
}

func URLSession(session: NSURLSession, dataTask: NSURLSessionDataTask, didReceiveResponse response: NSURLResponse, completionHandler: (NSURLSessionResponseDisposition) -> Void) {
