Question

我正在开发一个新应用，我要求用户通过电话号码注册，以便我可以将其存储在Parse.com的数据库中。我这样做是为了使用相同的电话号码发送推送通知。

我一直试图通过使用Twilio和Parse.com来实现这一目标。我在这里阅读了教程，但我试图顺利完成它。

这是我的云代码（如上面链接的网址所示）

var twilio = require('twilio')('removed', 'removed');

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: "+46 10 138 91 84",
    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.");
    }
 });

这是我在Xcode中调用的代码：

NSString *number = @"0737879108";
NSDictionary *params = [NSDictionary dictionaryWithObject:number forKey:@"number"];
//NSLog(@"%@", params);

[PFCloud callFunctionInBackground:@"sendVerificationCode" withParameters:params block:^(id object, NSError *error) {
    NSString *message = @"";
    if (!error) 
        message = @"Your SMS invitation has been sent!";
    } else {
        message = @"Uh oh, something went wrong :(";
    }
   [[[UIAlertView alloc] initWithTitle:@"Invite Sent!"
                                message:message
                               delegate:nil
                               cancelButtonTitle:@"Ok"
                               otherButtonTitles:nil, nil] show];
  }];

为什么我收到此错误消息？

TypeError: Cannot call method 'set' of null
at main.js:7:10 (Code: 141, Version: 1.6.1)

错误非常简单。您使用user来调用set方法。它说TypeError: Cannot call method 'set' of null。所以，问题在于你叫user。尝试调试用户或检查Parse.User.current()是否返回正确的用户。

来自Cloud-Code的错误消息，使用parse.com
