Mongoose - 无法使用 `findOrCreate` 创建超过 4 个字段 [英] Mongoose - Unable to create more than 4 fields using `findOrCreate`

问题描述

我正在使用 Node.js、MongoDB 和 Mongoose，并使用passport.js 进行身份验证.

I am using Node.js, MongoDB with Mongoose and am using passport.js for authentication.

这是我的用户架构:

const userSchema = new mongoose.Schema({
  email: String,
  password: String,
  googleId: String,
  facebookId: String,
  profilePic: String,
  fName: String,
  lName: String
});

还有我的谷歌策略:

passport.use(
  new GoogleStrategy(
    {
      clientID: process.env.CLIENT_ID,
      clientSecret: process.env.CLIENT_SECRET,
      callbackURL: "http://localhost:3000/auth/google/dashboard",
      profileFields: ["id", "displayName", "photos", "email"]
    },
    function(accessToken, refreshToken, profile, cb) {
      console.log(profile);
      console.log(profile.photos[0].value);
      User.findOrCreate(
        { googleId: profile.id },
        { profilePic: profile.photos[0].value },
        { email: profile.emails[0].value },

        function(err, user) {
          return cb(err, user);
        }
      );
    }
  )
);

当我 console.log 我的结果时，我看到了我的个人资料，以及个人资料照片 URL 和个人资料电子邮件，但我看不到我的电子邮件 ID.只创建了 4 个字段:

When I console.log my result I see my profile, along with profile photo url and profile email but I am unable to see my email id. Only 4 fields are getting created :

• _id
• googleId
• profilePic
• _v

谁能告诉我如何让电子邮件字段也保存?

Can someone tell me how to get the email field to save too?

推荐答案

您遇到问题的原因:
您没有很好地使用 findOrCreate 方法.findOrCreate 最多可以接受四个参数.
findOrCreate(conditions, doc, options, callback):

Why you are having the issue:
You are not using the findOrCreate method well. findOrCreate can take up to four arguments.
findOrCreate(conditions, doc, options, callback):

• conditions:用于指定选择过滤器找到文档.
• doc[可选]:如果没有找到匹配 selection-filter(conditions) 的文档，则将这个 doc 与你在 conditions 中有什么然后插入到数据库中.
• options[optional]:从插件代码库，我想你可以使用options.upsert(如果设置为 true)更新文档，如果它已经存在.
• callback:操作完成后执行的函数.

• conditions: This is used to specify the selection-filter to find the document.
• doc[optional]: If a document that matches the selection-filter(conditions) is not found, this doc is merged with what is you have in conditions and then inserted into the DB.
• options[optional]: From the plugin codebase, I figured you can use options.upsert(if set to true) to update the document if it already exist.
• callback: The function executed after the operation is done.

你做错的是 passign { email: profile.emails[0].value } 作为第三个参数，其中 options 是预期的，你应该包括它在 doc 中，即第二个参数.

What you are doing wrong is passign { email: profile.emails[0].value } as the third argument where options is expected, you are supposed to include it in the doc i.e the second argument.

修复
试试这个:

passport.use(
  new GoogleStrategy(
    {
      clientID: process.env.CLIENT_ID,
      clientSecret: process.env.CLIENT_SECRET,
      callbackURL: "http://localhost:3000/auth/google/dashboard",
      profileFields: ["id", "displayName", "photos", "email"]
    },
    function(accessToken, refreshToken, profile, cb) {
      console.log(profile);
      console.log(profile.photos[0].value);
      User.findOrCreate(
        { googleId: profile.id },
        // Notice that this function parameter below 
        // includes both the profilePic and email
        { profilePic: profile.photos[0].value, email: profile.emails[0].value },
        function(err, user) {
          return cb(err, user);
        }
      );
    }
  )
);
