问题描述

我正在使用axios并收到400错误的请求错误.我正在使用react-redux并尝试将发布请求发送到localhost:3000/posts.这是我正在使用的代码.

I am using axios and getting a 400 bad request error. I am using react-redux and trying to send a post request to localhost:3000/posts. Here is the code that I am using.

import axios from 'axios';
import {
  GET_ALL_POSTS,
  GET_POST,
  CREATE_POST,
  DELETE_POST,
  UPDATE_POST
} from './types';

const ROOT_URL = 'http://localhost:3000';

export function createPost({content, title}, cb) {
  return function(dispatch) {
    axios.post(`${ROOT_URL}/posts`, {content, title})
      .then((response) => {
        console.log(response);
        dispatch({
          type: CREATE_POST,
          payload: response
        });
      })
      .then(() => cb())
      .catch((error) => {
        console.log("Problem submitting New Post", error);
      });
  }
}

推荐答案

对于每个发布请求，客户端首先发送一个OPTIONS请求，以检查服务器是否准备好接受连接.您还应该允许服务器接受选项请求.如果不允许，请在节点服务器的情况下使用以下行

For every post request, the client first sends an OPTIONS request to check whether the server is ready to accept the connection. You should also allow the server to accept options request. If you have not allowed use the below lines in case of node server

app.use(function(req, res, next) {
   res.header('Access-Control-Allow-Methods', 'POST, GET, OPTIONS');
      next();
});
