不断收到 http 传输安全错误，即使我添加了绕过安全性的代码

Question

我尝试了很多不同的方法，通常我使用的代码都有效。但是在这种情况下，我不确定它是否与我使用的教程中的代码有关。他们使用 https 而不是 http。我尝试了不同的方法我不知道该怎么做！任何意见，将不胜感激。

 @IBAction func signinTapped(sender : UIButton) {
    let username:NSString = txtUsername.text!
    let password:NSString = txtPassword.text!

    if ( username.isEqualToString("") || password.isEqualToString("") ) {

        let alertView:UIAlertView = UIAlertView()
        alertView.title = "Sign in Failed!"
        alertView.message = "Please enter Username and Password"
        alertView.delegate = self
        alertView.addButtonWithTitle("OK")
        alertView.show()
    } else {

        do {
        let post:NSString = "username=\(username)&password=\(password)"

        NSLog("PostData: %@",post);
            let url = NSURL(string:"http://")

        let postData:NSData = post.dataUsingEncoding(NSASCIIStringEncoding)!

        let postLength:NSString = String( postData.length )

        let request:NSMutableURLRequest = NSMutableURLRequest(URL: url!)
        request.HTTPMethod = "POST"
        request.HTTPBody = postData
        request.setValue(postLength as String, forHTTPHeaderField: "Content-Length")
        request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
        request.setValue("application/json", forHTTPHeaderField: "Accept")


        var reponseError: NSError?

                NSLog("Response ==> %@", responseData);

                //var error: NSError?

                let jsonData:NSDictionary = try NSJSONSerialization.JSONObjectWithData(urlData!, options:NSJSONReadingOptions.MutableContainers ) as! NSDictionary


                let success:NSInteger = jsonData.valueForKey("success") as! NSInteger

                //[jsonData[@"success"] integerValue];

                NSLog("Success: %ld", success);

                if(success == 1)
                {
                    NSLog("Login SUCCESS");

                    prefs.synchronize()

                    self.dismissViewControllerAnimated(true, completion: nil)
                } else {

            if let error = reponseError {
                alertView.message = (error.localizedDescription)
            }

            alertView.message = "Server Error"
            alertView.delegate = self
            alertView.addButtonWithTitle("OK")
            alertView.show()
        }
    }

}

func textFieldShouldReturn(textField: UITextField) -> Bool {   //delegate method
    textField.resignFirstResponder()
    return true
}

}

我建议将 CFNETWORK_DIAGNOSTICS 环境变量设置为 3，运行您的应用程序并查看它记录的错误。这应该会给你一些关于出了什么问题的迹象。

很可能，您的 ATS 异常在某些方面是错误的。
