How to change PFUser password in Swift?

问题

I've tried updating the same way you would update a PFUser's email and even tried converting obj-c code (from other questions); neither worked. I also have no idea how to use Cloud Code (well...I installed it but I don't know how to pass information into Cloud Code or how to use JavaScript). Is there a way to update a users password without having to send the reset email?

回答1:

You can not change a user's password that way for security reasons. You have two choices

Password Reset Email
Cloud Code Function to Reset the Password

As I understand that you do not know JavaScript, here is a cloud code function that you can use to reset the user's password, as well as a way to call the function using Swift.

Function (in JavaScript):

Parse.Cloud.define("changeUserPassword", function(request, response) {
  // Set up to modify user data
  Parse.Cloud.useMasterKey();
var query = new Parse.Query(Parse.User);
query.equalTo("username", request.params.username);  // find all the women
query.first({
  success: function(myUser) {
    // Successfully retrieved the object.
myUser.set("password", request.params.newPassword);

myUser.save(null, {
        success: function(myUser) {
          // The user was saved successfully.
          response.success("Successfully updated user.");
        },
        error: function(myUser, error) {
          // The save failed.
          // error is a Parse.Error with an error code and description.
          response.error("Could not save changes to user.");
        }
      });

  },
  error: function(error) {
    alert("Error: " + error.code + " " + error.message);
  }
});
});

Swift code to call the above function:

PFCloud.callFunctionInBackground("changeUserPassword", withParameters: ["username" : "MyCoolUsername", "newPassword" : passwordField.text]) {
  (result: AnyObject?, error: NSError?) -> Void in
  if (error == nil) {
    // result is "Successfully updated user."
  }
}

Good luck!

Yes, password can be changed without Cloud Code and e-mail. After changing "password" field for current user session is reset, but you can restore it by calling PFUser.logInWithUsername again.

let currentUser = PFUser.current()
currentUser!.password = "<new_password>"

currentUser!.saveInBackground() { (successed, error) in
    if successed {
        PFUser.logInWithUsername(inBackground: currentUser!.email!, password: currentUser!.password!) { (user, error) in
            // Your code here...
        }
    }
}
