您好,我正在开发一个反应/快速应用程序。我已经能够从我的服务器发出GET请求,但是,我无法发出POST请求。当我这样做时,我的服务器正在返回一个空的主体。我将body-parser作为一个依赖项,接受json作为内容,但仍然没有运行空的正文。我的代码和服务器/客户端依赖关系如下。如果你们看到我没有看到的东西,请告诉我。从React快速发送POST请求返回空体

Index.js

const express = require('express'); 
const path = require('path'); 
const app = express(); 
const bodyParser = require('body-parser'); 

//routes 
require('./routes/sendMessageToEmail')(app); 
require('./routes/helloWorld')(app); 

app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: true })); 

app.use(express.static(path.join(__dirname, 'client/build'))); 
app.get('*', (req, res) => { 
res.sendFile(path.join(__dirname+'/client/build/index.html')); 
}); 

const port = process.env.PORT || 1111; 
app.listen(port); 

当我切换围绕在我的路线在我的index.js文件中声明的顺序,例如,宣布路由线

app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: true })); 

行,我得到一个未定义的反对空的身体。

POST路线

module.exports = app => { 
    app.post('/api/message', (req, res) => { 
     console.log('>>>>>>>>>> ', req.body); 
     res.send(req.body) 
    }); 
    } 

我的console.log将返回一个空的对象。我已经在postman中发布了post请求,从我的浏览器,curl等等。我得到了一个200状态响应,但是,body仍然是空的。

服务器的package.json

{ 
    "name": "Blog", 
    "version": "1.0.0", 
    "engines": { 
    "node": "6.11.1"

    "express": "^4.15.3" 
    } 
} 

客户的package.json

    "private": true, 
    "dependencies": {

    "eject": "react-scripts eject" 
    }, 
    "proxy": "http://localhost:1111/" 
} 

阵营POST路线

import axios from 'axios'; 

const sendToExpress = (input) => { 
return fetch('/api/message', { 
    mode: 'no-cors', 
    method: 'POST', 
    headers: { 
    Accept: 'application/json', 
    'Content-Type': 'application/json', 
    }, 
    body: JSON.stringify({message: 'asdfafa;k'}) 
    //body: JSON.stringify({"message": input}) 
    }) 
} 


//ACTION CREATORS 

export const sendInputToServer = (input) => ({ 
type: 'SEND_INPUT_TO_SERVER', payload: sendToExpress(input) 
}); 

任何帮助表示赞赏这里弄清楚为什么我的帖子reques t正在返回一个空的身体。

你的路由肯定需要去体解析器中间件。另外,在你的路线中,你可能也想使用res.json()而不是result.send,因为你的客户希望接收json – SlimSim

嘿,我切换了路线并尝试了res.json(),但仍然没有雪茄。还有什么你可以看到我的代码可能是一个问题,后体返回空? – Generaldeep

尝试删除这一行:

mode: 'no-cors'

为我工作。
