Question

我使用node.js v4.6.0以及express，request和body-parser的最新版本，但我收到的错误代码是我无法修复的，有什么想法吗？

这是我的代码：

var express = require('express');
var request = require('request');
var bodyparser = require('body-parser');

var app = express();
app.use(bodyparser.urlencoded({extended: true}))

    var webhook = process.env.DISCORD_WEBHOOK;

app.get('/', (req, res) => {
    res.sendFile(__dirname + '/index.html');
});

app.post('/webhook', (req, res) =>{
    request({
        method: 'POST',
        url: webhook,
        json: {
            "content": req.body.msg,
            "username": "Potato"
        }
    });

    res.redirect("/");
});

app.listen(80, () => {
    console.log("Server Started!");
});

并收到错误消息：

任何修复？

Answer 1

您需要在提出请求时提供网址信息，请检查您的网络链接变量是否已分配正确的网址，即

var webhook = process.env.DISCORD_WEBHOOK; //应为webhook分配有效的网址，例如：＆＃39; https://stackoverflow.com/＆＃39;

试的console.log（网络挂接）;

找出您要提出请求的网址。

Answer 2

对象请求有参数uri not url。 https://github.com/request/request#multipartrelated

 request({
    method: 'POST',
    uri: webhook,
    json: {
        "content": req.body.msg,
        "username": "Potato"
    }
});

错误：options.uri是必需参数
