Parse.com更新用户Cloud Code给出错误206:无法修改用户 [英] Parse.com update user Cloud Code giving error 206: cannot modify user

问题描述

我正在尝试在Parse Server上编写一个简单的Cloud Code函数，以更新用户的参数.我的功能如下:

I am trying to write a simple Cloud Code function on Parse Server that updates a user's paramater. My function is as follows:

Parse.Cloud.define("updateUser", function(request, response) {
    var query = new Parse.Query("User");
    query.equalTo("username", request.params.username);
    var type = request.params.type;
    query.first({
        success: function (user) {
            user.set("userType", type);
            user.save(null, {
                success: function (object) {
                    response.success("SUCCESS");
                }, error: function (object, error) {
                    response.error(error);
                }
            });
        }, error: function (error) {
            response.error(error);
        }
    });
});

这就是我从Express Node.js应用程序调用函数服务器端的方式:

And this is how I call the function server-side from an Express Node.js app:

Parse.Cloud.run("updateUser", { useMasterKey: true, username: req.body.username, type: req.body.type }, {
    success: function(final) {
        res.send({ res: "SUCCESS" });
    }, error: function(error) {
        res.send({ res: error });
    }
});

第一个查询返回一个用户，但随后的保存将引发"206:无法修改用户"错误.

The first query returns a user, but the subsequent save throws a "206: cannot modify user" error.

此功能在我们以前的平台上效果很好，但现在在Parse Server上引起了问题.

This function worked great on our previous platform, but now is causing issues on Parse Server.

非常感谢您的帮助.

推荐答案

应该将useMasterKey发送到您的云代码方法的user.save()，并在您的代码中从nodeJS应用发送了useMasterKey.

the useMasterKey should be send to the user.save() of your cloud code method and in your code you sent the useMasterKey from your nodeJS app.

因此，最后，您的代码应如下所示:

so at the end your code should look like the following:

Parse.Cloud.define("updateUser", function(request, response) {
var query = new Parse.Query("User");
query.equalTo("username", request.params.username);
var type = request.params.type;
query.first({
    success: function (user) {
        user.set("userType", type);
        user.save({useMasterKey : true}, {
            success: function (object) {
                response.success("SUCCESS");
            }, error: function (object, error) {
                response.error(error);
            }
        });
    }, error: function (error) {
        response.error(error);
    }
});

});

我还将根据最佳实践将代码更改为使用Promises和arrow函数.

I would also change my code to use Promises and arrow functions according to the best practices.
