我无法在我的角度应用程序上使用netlify函数创建表单数据的创建请求

我正在尝试将本教程https://www.netlify.com/blog/2018/07/09/building-serverless-crud-apps-with-netlify-functions--faunadb/应用在我的angular7前端项目上。

我的netlify功能:

/* code from functions/todos-create.js */
import faunadb from 'faunadb' /* Import faunaDB sdk */

/* configure faunaDB Client with our secret */
const q = faunadb.query
const client = new faunadb.Client({
  secret: process.env.FAUNADB_SECRET
})

/* export our lambda function as named "handler" export */
exports.handler = (event, context, callback) => {
  /* parse the string body into a useable JS object */
  const data = JSON.parse(event.body)
  console.log("Function `todo-create` invoked", data)
  const todoItem = {
    data: data
  }
  /* construct the fauna query */
  return client.query(q.Create(q.Ref("classes/todos"), todoItem))
  .then((response) => {
    console.log("success", response)
    /* Success! return the response with statusCode 200 */
    return callback(null, {
      statusCode: 200,
      body: JSON.stringify(response)
    })
  }).catch((error) => {
    console.log("error", error)
    /* Error! return the error with statusCode 400 */
    return callback(null, {
      statusCode: 400,
      body: JSON.stringify(error)
    })
  })
}

我的服务:

import { Injectable } from '@angular/core';
import { Mission } from 'src/app/shared/models';

@Injectable({
  providedIn: 'root'
})
export class MissionService {

  public mission = new Mission();
  myTodo = {
    title: 'My todo title',
    completed: false,
  };

  constructor() { }

  createTodo(data) {
    return fetch('/.netlify/functions/todos-create', {
      body: JSON.stringify(data),
      method: 'POST'
    }).then(response => {
      return response.json();
    });
  }
}

按照教程中的要求,我将其添加到package.json的末尾:

"proxy": {
    "/.netlify/functions": {
      "target": "http://localhost:4200",
      "pathRewrite": {
        "^/\\.netlify/functions": ""
      }
    }
  }

但我认为应该使用“ http://localhost:4200”的角度地址

我在单击表单按钮时应用了createTodo,但是:

  

“ ERROR错误:”未捕获(承诺):SyntaxError:JSON.parse:   在Firefox中,JSON数据的第1行第1列出现意外字符”

AND

  

“来自:: ffff:127.0.0.1的请求:POST / todos-create响应与   12毫秒内状态为500。调用期间发生错误:TypeError:n不是   功能”

答案 0 :(得分:0)

您需要查看netlify函数接收到的事件是什么。看起来主体不是JSON.parse期望的字符串形式的JSON对象。鉴于GET调用没有主体,这不足为奇。
