调用云代码解析Swift

Question

我试图在我的应用程序中使用电话号码验证。在注册期间，用户将被要求提供他们的电话号码，并被发送一个验证代码，他们将输入代码，如果它匹配，他们可以继续。我已经准备好了云代码，但我不知道如何从应用程序中准确地调用它。如能提供任何帮助，将不胜感激。

我想要做的是，当他们输入他们的电话号码，并按下继续，首先检查电话号码是一个有效的电话号码，然后发送短信代码。最后，返回到他们输入代码的验证视图，如果不匹配，则显示警报，如果匹配，则将用户登录

云代码：

var twilioAccountSid = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
var twilioAuthToken = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
var twilioPhoneNumber = '+1555-555-5555';
var secretPasswordToken = '1234';


var twilio = require('twilio')(twilioAccountSid, twilioAuthToken);

Parse.Cloud.define("sendVerificationCode", function(request, response) {
               var verificationCode = Math.floor(Math.random()*999999);
               var user = Parse.User.current();
               user.set("phoneVerificationCode", verificationCode);
               user.save();

               twilio.sendSms({
                              From: twilioPhoneNumber,
                              To: request.params.phoneNumber,
                              Body: "Your verification code is " + verificationCode + "."
                              }, function(err, responseData) { 
                              if (err) {
                              response.error(err);
                              } else { 
                              response.success("Success");
                              }
                              });
               });
Parse.Cloud.define("verifyPhoneNumber", function(request, response) {
               var user = Parse.User.current();
               var verificationCode = user.get("phoneVerificationCode");
               if (verificationCode == request.params.phoneVerificationCode) {
               user.set("phoneNumber", request.params.phoneNumber);
               user.save();
               response.success("Success");
               } else {
               response.error("Invalid verification code.");
               }
               });

这就是我称之为云代码的地方：

@IBOutlet weak var continueButton: UIButton!
@IBOutlet weak var phoneNumberTextField: UITextField!
@IBAction func continueButtonTapped(sender: AnyObject) {
    var phoneNumber = self.phoneNumberTextField.text

    if phoneNumber?.utf16.count < 10 {
        displayAlert("Error", message: "You must enter a valid 10 digit US phone number including area code")
    } else {
        let params = phoneNumber
        PFCloud.callFunctionInBackground("sendVerificationCode", withParameters: params, block: { (object: AnyObject?, error) -> Void in
            if error == nil {
                self.performSegueWithIdentifier("showVerifyUserView", sender: self)
            } else {

                // Do error handling
            }
        })
    }
}

您应该使用以下方法：

public class func callFunctionInBackground(function: String, withParameters parameters: [NSObject : AnyObject]?, block: PFIdResultBlock?)

您可以这样调用您的函数：

        PFCloud.callFunctionInBackground("sendVerificationCode",
        withParameters: /* any needed params here, for example mobile phone*/)
        { [unowned self](object:AnyObject?, error:NSError?) -> Void in
            guard error == nil else {
                //handle error
                return
            }
             // everything ok
             // notify your app that code is send successfully  

    }

然后，当用户输入代码时，也要这样做：

        PFCloud.callFunctionInBackground("verifyPhoneNumber",
        withParameters: /* any needed params here, for example verification code*/)
        { [unowned self](object:AnyObject?, error:NSError?) -> Void in
            guard error == nil else {
                //handle wrong notification code
                return
            }
            // code is ok, notify your app verification is complete
    }

不要忘记部署您的代码来使用命令行实用工具进行解析+考虑到向云代码发送参数的常见方法是发送字典

更新，如何发送参数：

PFCloud.callFunctionInBackground("functionName",
            withParameters: ["phoneNumber" : phoneNumber)
            { [unowned self](object:AnyObject?, error:NSError?) -> Void in
                ...


        }

假设您已经将代码部署到Parse (命令行"parse“)中，则可以使用PFCloud.callFunctionInBackground()调用云函数。请参阅https://www.parse.com/docs/ios/api/Classes/PFCloud.html
