Question

我正在关注 ben 的 typescript GraphQL Redis 教程我是 typescript 新手，第一次尝试 redis当我添加属性 req.session.userId= user.id;

类型错误:参数类型无效在encodeCommand (C:\Users\vikash patel\Desktop\reddit\node_modules@redis\client\dist\lib\client\RESP2\encoder.js:17:19

我的 main.ts 代码

declare module "express-session" {
interface SessionData {
userId: number | undefined;
}
}

import connectRedis from "connect-redis";
import { MyContext } from "./types";

const main = async () => {
const orm = await MikroORM.init(microConfig);
await orm.getMigrator().up();
const app = express(); 

const RedisStore = connectRedis(session);
const redisClient = redis.createClient() as any;
await redisClient.connect();
console.log("redis connected",redisClient.isOpen);

app.use(
  session({
    name: "qid",
    store: new RedisStore({
      client: redisClient,
      disableTouch: true,
      // disableTTL: true,
    }),
    cookie: {
      maxAge: 1000 * 60 * 60 * 24 * 365, //1year
      httpOnly: true,
      sameSite: "lax", //protecting csrf
      // secure:__prod__  //cookie only works in https
    },
    secret: "hellovikash",
    resave: false,
    saveUninitialized: false,
  })
);

const apolloserver = new ApolloServer({
  schema: await buildSchema({
    resolvers: [HelloResolver, PostResolver, UserResolver],
    validate: false,
}),
context: ({ req, res }): MyContext => ({ em: orm.em, req, res }),
});

await apolloserver.start();

apolloserver.applyMiddleware({ app });

// app.get("/",(_,res)=>{
//   res.send("ehllo")
// })

app.listen(4000, () => console.log("server is running on port 4000"));

我的用户.ts

@Mutation(() => USerResponse)
  async login(@Arg('options', () => UsernamePasswordInput) options: 
UsernamePasswordInput,
      @Ctx() { em, req }: MyContext
  ): Promise<USerResponse> {
    const user = await em.findOne(User, { username: options.username.toLowerCase() })
    if (!user) {
        return {
            errors: [{
                field: "username",
                message: "could not find username"
            }]
        }
    }
    const valid = await argon2.verify(user.password, options.password);
    if (!valid) {
        return {
            errors: [{
                field: "username",
                message: "password is incorrect"
            }]
        }
    }

      req.session.userId= user.id;   //This is the line which is creating error

      return {
        user
      };
  }

我的类型.ts

import { EntityManager, IDatabaseDriver, Connection } from "@mikro-orm/core"
import { Request, Response } from "express"

export type MyContext = {
  em: EntityManager<any> & EntityManager<IDatabaseDriver<Connection>>
  // req: Request;
  req: Request & { session: Express.SessionStore };
  res: Response;
}

我真的很笨...请帮忙:)

您需要创建启用 legacyMode 的 Redis 客户端:

const redisClient = createClient({ legacyMode: true });

如果您使用的是最新的 redis v4 ( https://github.com/tj/connect-redis )，则这是 connect-redis 软件包的限制。
