typescript - 使用 passport.serializeUser 时如何修复 "No overload matches this call."错误？

Question

我正在使用 TypeScript 开发 passport.serializeUser。

passport.serializeUser((user: User, done) => {
    done(null, user.id)
});

这是我得到的错误:

No overload matches this call.
  Overload 1 of 2, '(fn: (user: User, done: (err: any, id?: unknown) => void) => void): void', gave the following error.
    Argument of type '(user: import("/Users/minseokim/Documents/dev/project/my-todo/models/user").default, done: (err: any, id?: unknown) => void) => void' is not assignable to parameter of type '(user: Express.User, done: (err: any, id?: unknown) => void) => void'.
      Types of parameters 'user' and 'user' are incompatible.
        Type 'User' is missing the following properties from type 'User': id, email, password, nickname, and 31 more.
  Overload 2 of 2, '(fn: (req: IncomingMessage, user: User, done: (err: any, id?: unknown) => void) => void): void', gave the following error.
    Argument of type '(user: User, done: (err: any, id?: unknown) => void) => void' is not assignable to parameter of type '(req: IncomingMessage, user: User, done: (err: any, id?: unknown) => void) => void'.
      Types of parameters 'user' and 'req' are incompatible.
        Type 'IncomingMessage' is missing the following properties from type 'User': id, email, password, nickname, and 30 more.

Answer 1

要做的是在声明文件上扩展接口(interface)以添加更多重载，方法是将此代码用于 ./types/passport.d.ts 文件。

import { User } from '../models/Users' // export interface User { _id: string, ... }

declare module 'passport' {
  interface Authenticator {
    serializeUser<TID>(fn: (user: User, done: (err: any, id?: TID) => void) => void): void;
  }
}

然后用这个配置你的./tsconfig.json。

{
  "compilerOptions": {
    "typeRoots": ["./types"],
    ...
  }
}

最后，您的代码应该可以正常运行。

passport.serializeUser((user: User, done) => {
    done(null, user.id)
});

请记住，您也可以使用 user: any 来防止出现此错误。
