Deno HTTP 服务器无法在使用 Oak 的 Deno 部署上工作

Question

您好，我在将 Deno 服务器部署到 Deno Deploy 时遇到问题。 我想这与 Bcrypt 库有关，但我不知道如何用另一个库或部署设置来解决这个问题？

我使用 Oak 作为我的中间件：

import { Application } from "https://deno.land/x/[email protected]/mod.ts";
import router from "./controllers/routes/routes.ts";

const app = new Application();
const PORT = 8080;

app.use(router.routes());
app.use(router.allowedMethods());

console.log(`Application is listening on port: ${PORT}`);

await app.listen({ port: PORT });

例如此代码具有登录功能。 API 工作正常，但每当涉及到 Bcrypt 时，它都会给出错误“ReferenceWorker - Worker 未定义” 这是我使用 Bcrypt 库的示例：

import db from "./database/connectDB.ts";
import * as bcrypt from "https://deno.land/x/[email protected]/mod.ts";
import { pbkdf2 } from "https://deno.land/x/[email protected]/src/auth/pbkdf2.ts";
import { UserSchema } from "./schema/user.ts";
import { create, verify } from "https://deno.land/x/[email protected]/mod.ts";
import { key } from "./utils/apiKey.ts";
import { passwordTest, validateEmail } from "./utils/filters.ts";

const users = db.collection<UserSchema>("users");

export const signin = async ({ req, res }: { req: any; res: any }) => {
  const body = await req.body();
  const { username, password } = await body.value;

  if (!username || !password) {
    res.status = 400;
    res.body = {
      message: `Please provide all required fields: username and password.`,
    };
    return;
  }

  const user = await users.findOne({ username });
  if (!user) {
    res.status = 404;
    res.body = {
      message: `Invalid credentials`,
    };
    return;
  }

  const passwordMatch = await bcrypt.compare(password, user.password);
  if (!passwordMatch) {
    res.status = 401;
    res.body = {
      message: "Invalid credentials",
    };
    return;
  }

  const payload = {
    id: user._id,
    username: user.username,
  };
  const jwt = await create({ alg: "HS512", typ: "JWT" }, { payload }, key);
  
  if (jwt) {
    res.status = 200;
    res.body = {
      message: "User logged in",
      data: {
        _id: user._id,
        token: jwt,
        username: user.username,
      },
    };
  } else {
    res.status = 500;
    res.body = {
      message: "Internal server error",
    };
  }
};

Deno Deploy 不支持 Web Workers API。查看 bcrypt 的 documentation 有不使用 Web Workers 的同步方法。

用

bcrypt.compare

替换

bcrypt.compareSync

应该可以：

- const passwordMatch = await bcrypt.compare(password, user.password);
+ const passwordMatch = bcrypt.compareSync(password, user.password);
