node js 运行代码报错

This topic created in 2882 days ago, the information mentioned may be changed or developed.

function n(t) { return JSON.parse(a("5e5062e82f15fe4ca9d24bc561080e0e",atob(t),0,0,"012345677890123",1)) }

这种 atob 在 js 里面运行为啥报错呢？如何解决？

atob 是浏览器端方法，Node 中不存在的，需要使用 Buffer.from 方法转一下

```js
const btoa = str => Buffer.from(str).toString('base64');
const atob = str => Buffer.from(str, 'base64').toString();
```

@lizheming function n(t) {
return JSON.parse(a("5e5062e82f15fe4ca9d24bc561080e0e",Buffer.from(t, 'base64').toString(),0,0,"012345677890123",1))
}
我改成这样后，还是报错如下
N = decodeURIComponent(escape(N))
^
