Question

更新：已解决，恰好是我写的云代码不正确，请参阅更新＃3

我正在尝试使用Javascript中的Parse.com API为用户注册。仍然没有成功。

基本上我有一个用户字段和一个密码字段，当点击注册按钮时，尝试登录但总是有“错误代码：142：用户名已存在，请尝试登录错误来自解析api。

代码有什么问题？（我之前使用过c＃代码而且成功了）谢谢，谢谢。

function onSignupButtonClicked(button) {
    event.preventDefault();

    game_username = $("#loginUserText").val();
    game_password = $("#loginPasswordText").val();

    parseLogout(); // tried both logout earlier or put here..

    var user = new Parse.User();
    user.set("username", game_username);
    user.set("password", game_password);


    var progressCircle = showProgressCircle(); //some fullscreen progress

    //also tried user.signup(null, {.. with no luck

    Parse.User.signUp(game_username, game_password, {}, {
        success: function(user) {
            // Hooray! Let them use the app now.
            //NOW LOGIN

            login(game_username, game_password).then(function(result) {
                console.log(result); // "Stuff worked!"
                hideProgressCircle(progressCircle);

                $("#loginButton").attr("disabled", true);
                $("#logoutButton").attr("disabled", false);
                $("#signupButton").attr("disabled", true);

                game_manualLogin = true;
                isLoggedIn = true;


            }, function(err) {
                hideProgressCircle(progressCircle);

                console.log("loginPromise: " + err.message + " code: " + err.code); // Error: "It broke"
                   handleParseError(err);

            });

        },
        error: function(user, error) {
            // Show the error message somewhere and let the user try again.
                 hideProgressCircle(progressCircle);
               handleParseError(error);

        }
    });

}

更新：即使是基本的Parse.com javascript返回142 ..这里是代码，我的位置是伊斯坦布尔/土耳其

function register() {

    var user = new Parse.User();
    user.set("username", "testop");
    user.set("password", "testop");
    user.set("email", "email@example.com");

    // other fields can be set just like with Parse.Object
    user.set("phone", "415-392-0202");

    user.signUp(null, {
        success: function(user) {
            // Hooray! Let them use the app now.
            console.log("testop register ok!");

        },
        error: function(user, error) {
            // Show the error message somewhere and let the user try again.
            alert("Error: " + error.code + " " + error.message);
        }
    });


}

这是我在上面更新的代码中遇到的错误错误：代码：142：用户名已存在，请尝试登录（代码来自Parse Javascript Signup

更新＃2：即使Rest API也会出错：

MacBook-Pro:~ gg$ curl -X POST \
>   -H "X-Parse-Application-Id: MYAPPID" \
>   -H "X-Parse-REST-API-Key: MYRESTAPIKET" \
>   -H "X-Parse-Revocable-Session: 1" \
>   -H "Content-Type: application/json" \
>   -d '{"username":"testdude","password":"tesdude","phone":"415-392-0202"}' \
>   https://api.parse.com/1/users
{"code":142,"error":"User name already exists, try login"}
MacBook-Pro:~ gg$

更新＃3：用3 apis检查后，发现问题是我的错。我在用户保存时忘记了一个Cloud Code，因为它没有检查查询长度，所以它有问题。

Parse.Cloud.beforeSave(Parse.User, function(request, response) {
    var username = request.object.get("username");

    var usernamequery = new Parse.Query(Parse.User);
    usernamequery.equalTo("username", username);

    usernamequery.find({
        success: function()
        {
          --->>>should be checking length of query here  <<<---
         console.log("same user name found");
         response.error("User name already exists, try login");
        },
        error: function(error)
        {
         console.log("ok unique user name continue save");
         response.success("OK saving user");
        }   
    });


});

您需要两个表单，一个用于注册（作为新用户），调用Parse.User.signUp，另一个表单（用于返回用户）调用Parse.User.logIn。

问题是您只能使用用户名和密码“注册”一次，之后您应该“登录”。此外，当您从Parse.User.signUp获得成功回调后，用户就会登录，您无需拨打“登录”。

像这样的东西（两个事件监听器由两个不同的按钮触发）。

SIGNUP

function onSignupButtonClicked(button) {
    event.preventDefault();

    game_username = $("#loginUserText").val();
    game_password = $("#loginPasswordText").val();

    Parse.User.signUp(game_username, game_password, {}, {
        success: function(user) {
            // A new user has signed up and is now the Parse.User.current() user
            // Do something
        },
        error: function(user, error) {
            // Show the error message somewhere and let the user try again.         
        }
    });

}

LOGIN

function onLoginButtonClicked(button) {
    event.preventDefault();

    game_username = $("#loginUserText").val();
    game_password = $("#loginPasswordText").val();

    Parse.User.logIn(game_username, game_password, {}, {
        success: function(user) {
            // An existing user has logged in and is now the Parse.User.current() user
            // Do something
        },
        error: function(user, error) {
            // Show the error message somewhere and let the user try again.
        }
    });

}
