解析服务器/JS SDK，保存用户对象时出现错误 206

问题描述

我在使用 Parse Server JS SDK 编辑和保存用户时遇到问题.

I am having trouble using the Parse Server JS SDK to edit and save a user.

我正在登录，登录并检索用户就好了，我可以毫无例外地调用 user.set 并添加/编辑我想要的任何字段，但是当我尝试保存时，即使使用主密钥，我收到 Error 206: Can t modify user .

I am signing in, logging in and retrieving the user just fine, I can call without exception user.set and add/edit any field I want, but when I try to save, even when using the masterKey, I get Error 206: Can t modify user <id>.

我也尝试过使用 save 直接设置字段，结果相同.

I also have tried to use save to direcly set the fields, same result.

有趣的是，在数据库中，用户的架构会随着新的字段和类型进行更新.

A interesting thing is that in the DB, the User's Schema get updated with the new fields and types.

这是我的更新功能:

function login(user, callback) {
    let username = user.email,
        password = user.password;

    Parse.User.logIn(username, password).then(
        (user) => {
            if(!user) {
                callback('No user found');
            } else {
                callback(null, user);
            }
        },
        (error) => {
            callback(error.message, null);
        }
    );
}

function update(user, callback) {
    login(user, (error, user) => {
        if(error) {
            callback('Can t find user');
        } else {
            console.log('save');
            console.log('Session token: ' + user.getSessionToken());
            console.log('Master key: ' + Parse.masterKey);
            user.set('user', 'set');
            user.save({key: 'test'}, {useMasterKey: true}).then(
                (test) => {
                    console.log('OK - ' + test);
                    callback();
                }, (err) => {
                    console.log('ERR - ' + require('util').inspect(err));
                    callback(error.message);
                }
            );
        }
    });
}

错误示例:

update
save
Session token: r:c29b35a48d144f146838638f6cbed091
Master key: <my master key>
ERR- ParseError { code: 206, message: 'cannot modify user NPubttVAYv' }

如何正确保存我编辑过的用户?

How can I save correctly my edited user?

推荐答案

function login(logInfo, callback) {
    let username = logInfo.email,
        password = logInfo.password;

    Parse.User.logIn(username, password).then(
        (user) => {
            if(!user) {
                callback('No user found');
            } else {
                callback(null, user);
            }
        },
        (error) => {
            callback(error.message, null);
        }
    );
}

function update(userInfo, data, callback) {
    login(userInfo, (error, user) => {
        if(error) {
            callback('Can t find user');
        } else {
            getUpdatedData(user.get('data'), data, (error, updateData) => {
                if(error) {
                    callback(error);
                } else {
                    user.save({data: updateData}, /*{useMasterKey: true}*/ {sessionToken: user.get("sessionToken")}).then(
                        (test) => {
                            callback();
                        }, (err) => {
                            callback(error.message);
                        }
                    );
                }
            });
        }
    });
}

出于某种原因，重新尝试使用 sessionToken 有效.

For some reason, retrying to use sessionToken worked.
