每个Koa路线404s（打字稿）

Question

Problem

• Setting up Auth Controllers
• Using Bcrypt and JWT
• All POST Calls to Koa 404ing
• Calls to other routes working fine
• Possibly a issue with scope of code.

import * as Koa from 'koa';
import * as dotenv from 'dotenv';
import * as mongoose from 'mongoose';
import * as cors from '@koa/cors';
import * as bodyParser from 'koa-body';
import bookRouter from './routes/book';
import userRouter from './routes/user';
dotenv.config();

const app: Koa = new Koa();

mongoose.connect(process.env.MGO_URI, { useNewUrlParser: true }).catch(error => {
    console.log(error);
    console.log('\n application shutting down for safety \n');
    process.exit(1);
});

// application wide middleware
app.use(cors());
app.use(bodyParser());

// application routes
app.use(userRouter.routes());
app.use(bookRouter.routes());

app.listen(3000);
console.log('Server running on port 3000');

I am not struggling to generate passwords or save users to the DB and I am receiving data into the server from the controllers the only thing is my server is not sending back anything but a 404 error.

 import * as Koa from 'koa'; import * as dotenv from 'dotenv'; import * as mongoose from 'mongoose'; import * as cors from '@koa/cors'; import * as bodyParser from 'koa-body'; import bookRouter from './routes/book'; import userRouter from './routes/user'; dotenv.config(); const app: Koa = new Koa(); mongoose.connect(process.env.MGO_URI, { useNewUrlParser: true }).catch(error => { console.log(error); console.log('\\n application shutting down for safety \\n'); process.exit(1); }); // application wide middleware app.use(cors()); app.use(bodyParser()); // application routes app.use(userRouter.routes()); app.use(bookRouter.routes()); app.listen(3000); console.log('Server running on port 3000');

First off, if you are using an async request handler you should use await . It makes the code a lot cleaner. I think this should work (although I'm not positive if bcrypt return a promise, but I think it does), for example:

router.post('/signup', async ctx => {
  const { username, password, email } = ctx.request.body;
  try {
    let hash = await bcrypt.hash(password, 10);
    const user = new User({ username, password: hash, email });

    await user.save();
    ctx.status = 201;
  } catch(err) {
    console.log(err); // TODO: handle err
    ctx.status = 500;
  }
});
