护照-本地-猫鼬:创建策略不是函数/身份验证不是函数

我正在这个入门项目的基础上构建，并尝试使用护照本地猫鼬添加用户登录。

根据我尝试使用该策略的两种方式中的哪一种，我会收到此错误：

[1] passport.use(User.createStrategy());
[1]                   ^
[1] TypeError: User.createStrategy is not a function

或此错误：

[1] passport.use(new LocalStrategy(User.authenticate()));
[1]                                     ^
[1] TypeError: User.authenticate is not a function

我尝试在谷歌上搜索很多解决方案，但似乎找不到任何相关的东西。

编辑：据我了解，userSchema.plugin(passportLocalMongoose); ./models/user.ts应该将函数添加到模型中。配置护照/护照-本地和简化的护照/护照-本地配置显示如何设置它，但它似乎对我不起作用。

      return filename.substr(0, filename.length - 3);
    }

function resolve(root: string, modules): void {

// Connect to MongoDB
mongoose.connect('mongodb://localhost/test');
const db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', () => {
  console.log('MongoDB connected');
});

像这样更新你的 user.ts 文件：

import * as mongoose from 'mongoose';
import * as passportLocalMongoose from 'passport-local-mongoose';
import { PassportLocalSchema } from 'mongoose';
const userSchema = new mongoose.Schema({
  email: String,
  password: String,
  displayname: String,
  groups: [{
    type: mongoose.Schema.Types.ObjectId,
    ref: 'Group'
  }]
});
userSchema.plugin(passportLocalMongoose, {
  usernameField: 'email'
});
const User = mongoose.model('User', userSchema as PassportLocalSchema);
export default User;

它对我有用。

抱歉回答晚了。我找到了解决这个问题的方法。

import mongoose, { PassportLocalSchema  } from 'mongoose';
import passportLocalMongoose from 'passport-local-mongoose';
const { Schema } = mongoose;
const UserSchema = new Schema({});
UserSchema.plugin(passportLocalMongoose);
const User: mongoose.PassportLocalModel<mongoose.PassportLocalDocument> =
  mongoose.model('User', UserSchema as PassportLocalSchema );
export default User;

我遇到了同样的问题，我只需添加以下内容即可解决它：

 userSchema.plugin(passportLocalMongoose);

此代码在用户架构声明之前声明用户架构模型。

例：

mongoose.connect("mongodb://localhost:27017/userDB", {
      useNewUrlParser: true,
      useUnifiedTopology: true
    });
    // userSchema 
    const userSchema = new mongoose.Schema({
      email: String,
      password: String
    });
    //**Like this**
    userSchema.plugin(passportLocalMongoose);
   // User Schema model
   const User = new mongoose.model("User", userSchema);
   mongoose.set("useCreateIndex", true);

如果我能正确理解，这只是由未解析的类型引起的，而不是真正的代码错误。

要解决它 -

在项目中包括类型定义文件，这将扩展猫鼬中的类型：https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/passport-local-mongoose/index.d.ts
在 app.ts 中，从 mongoose 导入所需的类型(请注意，PassportLocalModel来自上面的定义文件(：

import { Document, PassportLocalModel } from "mongoose";

现在，您可以将更新的类型转换为User：

(User as PassportLocalModel<Document>).createStrategy()

(User as PassportLocalModel<Document>).authenticate()

为了解决这个问题，我检查了他们如何实际测试类型 - https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/passport-local-mongoose/passport-local-mongoose-tests.ts用法变得非常清晰。

以下对我有用(请注意PassportLocalDocument，PassportLocalSchema，PassportLocalModel的使用(：

import mongoose, {
  PassportLocalDocument,
  PassportLocalSchema,
  PassportLocalModel,
} from 'mongoose';
import passportLocalMongoose from 'passport-local-mongoose';
import { updateIfCurrentPlugin } from 'mongoose-update-if-current';
export enum UserStatus {
  Created = 'created',
  Approved = 'approved',
  Banned = 'banned',
}
export enum UserRole {
  Member = 'member',
  Admin = 'admin',
  Public = 'public',
}
// An interface for props to create a new user
interface UserAttrs {
  email: string;
  password: string;
  status?: UserStatus;
  role?: UserRole;
}
// An interface that describes the properties of User document
interface UserDoc extends PassportLocalDocument {
  email: string;
  password: string;
  status: UserStatus;
  role: UserRole;
}
// An interface that describes User model
export interface UserModel extends PassportLocalModel<UserDoc> {
  build(attrs: UserAttrs): UserDoc;
}
const userSchema = new mongoose.Schema(
  {
    email: {
      type: String,
      required: true,
    },
    password: {
      type: String,
      required: true,
    },
    status: {
      type: String,
      required: true,
    },
    role: {
      type: String,
      required: true,
    },
  },
  {
    toJSON: {
      transform(doc, ret) {
        delete ret.password;
        ret.id = ret._id;
        delete ret._id;
      },
    },
  },
) as PassportLocalSchema;
userSchema.set('versionKey', 'version');
userSchema.plugin(passportLocalMongoose, {
  usernameField: 'email',
});
userSchema.plugin(updateIfCurrentPlugin);
userSchema.statics.build = (attrs: UserAttrs) => {
  return new User(attrs);
};
const User = mongoose.model<UserDoc, UserModel>('User', userSchema);
export { User };

它对我有用。尝试使用以下格式：

userSchema.plugin(passportLocalMongoose);
const User  = mongoose.model("User",userSchema);

const session = require("express-session");
app.use(session({
  secret: "We have to remember this for future reference",
  resave: false,
  saveUninitialized: false
}));
app.use(passport.initialize());
app.use(passport.session());

只需在创建模型之前添加userSchema.plugins喜欢这个：

userSchema.plugin(passportLocal);
userSchema.plugin(findOrCreate);
userSchema.plugin(passportLocalMongoose);
const User = mongoose.model('Model',userSchema);

然后使用该模型。它的工作对我来说很好.
