如何使用lambda函数访问Get请求的内容

Question

我需要将对象实例存储在我的动物数据库DB中，但是我无法在前面获取他的内容

我试图找出控制台日志的问题，但是...

这是我的lambda函数

/* code from functions/todos-read.js */
import faunadb from 'faunadb'

const q = faunadb.query
const client = new faunadb.Client({
  secret: process.env.FAUNADB_SECRET
})

exports.handler = (event, context, callback) => {
  const id = '234316534878568967'
  console.log(`Function 'todo-read' invoked. Read id: ${id}`)
  return client.query(q.Get(q.Ref(q.Class("missions"), "234316534878568967")))
  .then((response) => {
    console.log("success", response)
    return callback(null, {
      statusCode: 200,
      body: JSON.stringify(response)
    })
  }).catch((error) => {
    console.log("error", error)
    return callback(null, {
      statusCode: 400,
      body: JSON.stringify(error)
    })
  })
}

我在角度服务中的职能：

  readById = () => {
    return fetch('/.netlify/functions/mission-read-by-id').then((response) => {
      console.log(response);
      return response.json();
    });
  }

然后我使用console.log将此函数分配给组件中的var

this.missionData = this.missionService.readById();
console.log(this.missionData);

控制台响应的结果：

[BACK] [LAMBDA] Request from ::ffff:127.0.0.1: GET /mission-read-by-id
[BACK] [LAMBDA] Function 'todo-read' invoked. Read id: 234316534878568967
[BACK] [LAMBDA] success { ref: Ref(Class("missions"), "234316534878568967"),
[BACK] [LAMBDA]   ts: 1559720511260000,
[BACK] [LAMBDA]   data:
[BACK] [LAMBDA]    { consultant: 'sd',
[BACK] [LAMBDA]      consultantEmail: 'sdq@gg.com' } }
[BACK] [LAMBDA] Response with status 200 in 256 ms.

console.log在组件中的结果：

{…}
?
__zone_symbol__state: true
?
__zone_symbol__value: {…}

??data: {…}
???
client: "dvs"
???
clientEmail: "sdq@gg.com"

<prototype>: Object { … }
??
ref: Object { "@ref": {…} }
??
ts: 1559720511260000
??
<prototype>: Object { … }
?
<prototype>: Object { then: then(), catch: catch(), finally: finally(), … }

我不明白如何得到我的东西，那么如果你能解释一下我的话...非常感谢

的readById返回的Promise是，您需要更改代码才能使用此代码：

this.missionService.readById().then(missionData => console.log(missionData))
// or using async/await
this.missionData = await this.missionService.readById();
console.log(this.missionData);
