ios - 如何使用 iOS Swift 在 REST Web 服务 URL 上应用 Cookie

Question

我已经从我的应用程序发出了 REST 请求，并且我能够正确获取数据。现在我想在此 Web 服务 URL 上应用身份验证 cookie。我们应该怎么做。请帮忙。下面是我当前的代码。

CallRestParser.swift - 在此 processRequest 方法将从某个 View Controller 调用。 processRequest 方法将接收 Web 服务 URL 并向 RESTParser 类发送请求。 getReceiveData 是一个委托(delegate)方法，连接成功后会调用该方法。

protocol UpdateProjectUIDelegate{
    func UpdateProjectUI(data:NSDictionary)
}
class CallRESTParser: NSObject, RESTParserDelegate {
    var rest1=RESTParser()
    var projectDelegate: UpdateProjectUIDelegate?
    func processRequest(url:String) {
        var nsURL = NSURL(string: url)
        var createrequest: NSMutableURLRequest = NSMutableURLRequest(URL: nsURL!)
        createrequest.HTTPMethod = "GET"
        rest1.delegate = self
        rest1.httpRequest(createrequest)

    }

    func getReceiveData(recvData:NSMutableData,sender:RESTParser){
        var error: NSError?

        var jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(recvData, options:NSJSONReadingOptions.MutableContainers, error: &error) as? NSDictionary

        if error != nil{
            print("Error occured  \(error?.localizedFailureReason)")
            return
        }
        println(jsonResult.count)
        projectDelegate?.UpdateProjectUI(jsonResult)
        //var updateUI = ProjectDetails_tab()
        //updateUI.updateUI()


    }
}

RESTParser.swift -

protocol RESTParserDelegate{
    func getReceiveData(data:NSMutableData,sender:RESTParser)
}


class RESTParser: NSObject, NSURLConnectionDataDelegate {

    var receiveData: NSMutableData!
    var requestConnection: NSURLConnection!
    var delegate: RESTParserDelegate?

    func receiveData(resData:NSMutableData){
        receiveData = resData
    }

    func requestConnection(reqConn:NSURLConnection){
        requestConnection = reqConn
    }

    func httpRequest(myRequest:NSMutableURLRequest){
        self.requestConnection = NSURLConnection(request: myRequest, delegate: self)

    }
    // NSURLConnectionDataDelegate methods
    func connection(connection: NSURLConnection, didReceiveResponse response: NSURLResponse){
        self.receiveData = NSMutableData()

    }

    func connection(connection: NSURLConnection, didReceiveData data: NSData){
        self.receiveData.appendData(data)
    }

    func connectionDidFinishLoading(connection: NSURLConnection){
        //if let revData = receiveData{
        self.delegate?.getReceiveData(receiveData, sender: self)
        //}else
        //{
          //  NSLog("No data : nil")
        //}
        self.delegate = nil
        self.receiveData = nil
        self.requestConnection = nil
    }
    func connection(connection: NSURLConnection, didFailWithError error: NSError){
        NSLog("Failed with error - %@ ",error.localizedDescription)

    }
    func connection(connection: NSURLConnection, canAuthenticateAgainstProtectionSpace protectionSpace: NSURLProtectionSpace) -> Bool{
        return protectionSpace.authenticationMethod  == NSURLAuthenticationMethodServerTrust
    }
    func connection(connection: NSURLConnection, didReceiveAuthenticationChallenge challenge: NSURLAuthenticationChallenge){
        if(challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust){
            if(challenge.protectionSpace.host == "domain.com"){
                let credentials = NSURLCredential(forTrust: challenge.protectionSpace.serverTrust)
                challenge.sender.useCredential(credentials, forAuthenticationChallenge: challenge)
            }
        }
        challenge.sender.continueWithoutCredentialForAuthenticationChallenge(challenge)

    }
}

我们从 authSessionCookieKeyVal 获得的身份验证 Cookie 是这样的 - XX-X-SESSION-ID=1_2_1_XXxXXXgSaG1K5aXXXXXXXV 。我如何在上述 REST 调用中应用此 cookie。请帮忙。

您必须在NSMutableURLRequest的header中传递cookie

    var nsURL = NSURL(string: url)
    var createrequest: NSMutableURLRequest = NSMutableURLRequest(URL: nsURL!)

    let cookieArray = NSArray(objects: Cookie1,Cookie2) // Cookie1 and Cookie2 is an object of NSHTTPCookie
    let cookieHeader = NSHTTPCookie.requestHeaderFieldsWithCookies(cookieArray)
    createrequest.allHTTPHeaderFields = NSDictionary(dictionary: cookieHeader)

编辑

Cookie 存储在 NSHTTPCookieStorage

    var Cookie1:NSHTTPCookie?  // Cookie Object
    var Cookie2:NSHTTPCookie? // Cookie Object
    let storage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
    let cookieArray = storage.cookies!

    for tempCookie in cookieArray
    {
        if tempCookie.name == "rtFa" // Write your cookie name which you want to search
        {
            Cookie1 = tempCookie as? NSHTTPCookie
            continue
        }
        else if tempCookie.name == "FedAuth" // Write your cookie name which you want to search
        {
            Cookie2 = tempCookie as? NSHTTPCookie
            continue
        }
    }

    if Cookie1 != nil && Cookie2 != nil
    {
        println("Cookie Found")
    }
    else
    {
        println("Cookie Not Found")
    }
