NodeJS应用编程接口测试

Question

我已经使用express & nodejs制作了一个本地express API，.This是我与所有express服务器的index.js文件：

const express = require("express");
const bodyParser = require("body-parser");
const mongoose = require("mongoose");
const PORT = process.env.PORT || 3000;

//Database models
const Panch = require('./models/panchayat');


// Starting the app
const app = express();
app.use(bodyParser.json());


//Connect to the db
(async() => {
    await mongoose.connect("mongodb://localhost/village", {
        useNewUrlParser: true,
        useUnifiedTopology: true
    });
})();

app.post("/api/fetchPanch/", (req, res) => {
    const body = req.body;
    console.log(body)
        // let result = Panch.find({
        //     "_id": _id
        // })
        // res.json(result);
});

app.listen(PORT, async() => {
    console.log(`Server is up and running on https://localhost:${PORT}`);
});

这是我用来测试API的文件：

const axios = require('axios');

axios.post('https://localhost:3000/api/fetchPanch', {
        'headers': {
            'Access-Control-Allow-Origin': '*'
        },
        'id': '5fd8eac45f2d508574c57fd5'
    })
    .then(res => res.json())
    .then((res) => {
        console.log(res);
    })

但是我在终端中得到了这样的响应：

node:internal/process/promises:227
          triggerUncaughtException(err, true /* fromPromise */);
          ^

我无法测试我的API。有没有人能帮我解决这个问题，请帮帮忙。

预先感谢，Japroz Saini

Answer 1

这就是为什么你在终端中得到它的原因:用与javascript内置的fetch API相同的方式来使用axios。

使用fetch API，您可以执行以下操作

fetch('http://url',params,body).then(res=>res.json()).then(res=>res).catch(err=>...)

在第一个链式then中，我执行了res.json()，在第二个链式中，我访问了实际数据。

但在axios中不需要执行res=res.json()，因为您可以直接访问第一个then中的数据，如下所示：

 axios.post('http://url',body).then(res=>res.data).catch(err=>...)

服务器发送的data在res object的data attribute中

Answer 2

如果您正在发出任何类型的get/post请求，则需要使用http。

const http = require('http')

将此代码添加到您的代码中，并在使用的地方将https替换为http。
