In response to the use of Promise return ctx.body, received '404 Not Found'.

In response to the use of Promise return ctx.body, received ‘404 Not Found’. But my mongodb is showing that the data was written. This troubled me, look forward to help.

router.get('/api/login', function *(next) {
  let request = this.request;
  let response = this.response;
  let params = request.query;
  userInfo.set({
    document: {
      user: params.name,
      password: params.password
    }
  })
  .then(res => {
    response.body = {
      code: 0,
      data: {
        uid: res.uid,
      }
    };
  })
  .catch(err => {
    response.body = {
      code: 999999,
      error: err
    }
  })
  yield next;
})

I’d personally suggest something like this:

try {
  this.body = yield userInfo.set({ ... })
} catch (error) {
  this.status = xxx
  this.body = { error }
}

Or omitting the try/catch portion and unifying your error-handling in middleware “upstream”.

just the last ctx.status = 200 ctx.body = {mes:‘fail’} do not works @tj
