【问题描述】:
我有一个问题,要制作两个 js 文件,一个放在“网站”目录中,另一个放在外面很多,它没有工作所以.. 这是我的服务器端代码
/* Empty JS object to act as endpoint for all routes */
projectData = {};
/* Express to run server and routes */
const express = require('express');
/* Start up an instance of app */
const app = express();
/* Dependencies */
const bodyParser = require('body-parser')
/* Middleware*/
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
const cors = require('cors');
app.use(cors());
/* Initialize the main project folder*/
app.use(express.static('website'));
const port = 3000;
/* Spin up the server*/
const server = app.listen(port, listening);
function listening(){
// console.log(server);
console.log(`running on localhost: ${port}`);
};
// GET route
app.post('/add', function (req, res) {
let data = req.body;
console.log(data);
});
// POST an animal
const data = []
app.post('/animal', addAnimal)
function addAnimal (req,res){
data.push(req.body);
console.log(data);
}
这就是我的客户端代码
/* Function to POST data */
const postData = async ( url = '', data = {})=>{
console.log(data)
const response = await fetch(url, {
method: 'POST', // *GET, POST, PUT, DELETE, etc.
credentials: 'same-origin', // include, *same-origin, omit
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(data), // body data type must match "Content-Type" header
});
try {
const newData = await response.json();
console.log(newData);
return newData
}catch(error) {
console.log("error", error);
// appropriately handle the error
}
}
// TODO-Call Function
postData('/addAnimal', {animal:'Tiger'});
postData('/addAnimal', {animal:'Lion'});
当我在 vs 代码编辑器中运行代码时,它会显示“{ animal: 'lion' } { 动物:'老虎'}"
但它从不控制台记录数据
