问题描述
使用 webpack 解决的问题
为了API的需要,我需要导入MD5
和moment
.我使用基本的 npm install
下载了包,但是当我尝试使用下面的代码将它导入到我的 app.js
上时:
const md5 = require('./node_modules/md5/md5.js');const moment = require('./node_modules/moment/moment.js');函数getTimeStamp(){return moment.utc().format('YYYYMMDDHHmmss');}让时间戳 = getTimeStamp();函数 generateSignature(devId、方法、authKey、时间戳){返回 md5 (`${devId}${method}${apiKey}${timestamp}`);}let signature = generateSignature(XXXX, "createsession", "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", getTimeStamp());
我在控制台中收到此消息:
Uncaught ReferenceError: require is not defined
我不知道我做错了什么,因为我在另一个程序中使用了相同的方法,并且效果很好......
提前致谢
您可能会看到此错误,因为 require() 在浏览器/客户端 JavaScript 中不存在.如果你想在浏览器中使用 require() ,那么你需要使用类似 require.js
RequireJS 是一个 JavaScript 文件和模块加载器.它针对在浏览器中使用,但可以在其他 JavaScript 环境中使用,比如 Rhino 和 Node.

Edit : Problem solved using webpack
For the needs of an API, I needed to import MD5
and moment
. I downloaded the packages using the basic npm install
but when I try to import it on my app.js
using the code below :
const md5 = require ('./node_modules/md5/md5.js');
const moment = require ('./node_modules/moment/moment.js');
function getTimeStamp () {
return moment.utc ().format ('YYYYMMDDHHmmss');
}
let timestamp = getTimeStamp ();
function generateSignature (devId, method, authKey, timestamp) {
return md5 (`${devId}${method}${apiKey}${timestamp}`);
}
let signature = generateSignature (XXXX, "createsession", "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", getTimeStamp ());
I get this message in the console :
Uncaught ReferenceError: require is not defined
I don't know what I'm doing wrong because I used the same method for another program and it worked perfectly...
Thanks in advance
You're probably seeing this error because require() does not exist in the browser/client-side JavaScript.If you want to use require() in the browser, then you need to use something like require.js
