IE中未定义“代理” [英] 'Proxy' is undefined in IE

问题描述

我通过React + Node +

有人知道

1. 如何解决此问题？


2. 我怎么知道哪个库/部件我的代码使用此 Proxy ？我可以用其他方式代替它。

编辑1：在 .umirc中。 ts ：

  treeShaking：是，
目标：{
即： 9，
 Safari：9，
}，
  

在 package.json ：

  umi： ^ 2.7.0，
 umi-plugin-react： ^ 1.8.0，
 umi-types： ^ 0.2.0 
  

编辑2：

我尝试了 yarn添加proxy-polyfill ，然后纱线开始。奇怪的是，它在本地主机无效字符和'umi'未定义：

解决方案

缺少一个polyfill。您是否检查了umi.js的此配置？ https://umijs.org/config/#targets

将ie的目标设置为11（如上面的链接）应该可以添加所需的polyfill。

 目标：{
即：11，
 ...其他浏览器
}，
 ...其余的配置
  

LE：

如果umi.js存在问题，您可以尝试添加自己需要填充（例如，这里是代理 https://github.com/GoogleChrome/proxy-polyfill ）

I have built an Excel add-in by React+Node+Umi. We have implemented our authentication system. The authentication works in Chrome and Safari, I just realized that it does not work well in IE11; F12 shows that 'Proxy' is undefined.

Although it is an Excel add-in, we could reproduce the error (and the same error message) just in browser. Open the link https://jsaddin.10studio.tech/welcome/?next=formulaEditor in IE 11, sign in with ID [e-mail] and password: 123456. We could see the error message in F12.

Does anyone know

1. how to fix this?
2. how could I know which library/part of my code uses this Proxy? I may replace it by alternatives.

Edit 1: In .umirc.ts:

treeShaking: true,
targets: {
  ie: 9,
  safari: 9,
},

In package.json:

"umi": "^2.7.0",
"umi-plugin-react": "^1.8.0",
"umi-types": "^0.2.0"

Edit 2:

I tried yarn add proxy-polyfill, then yarn start. Curiously, it raised an error in localhost Invalid character and 'umi' is undefined:

解决方案

It looks like you are missing a polyfill. Did you check this config for umi.js? https://umijs.org/config/#targets

Setting the target of ie to 11 (as in the above link) should handle adding the polyfills you need.

  targets: {
    ie: 11,
    ...other browsers
  },
  ...rest of the config

LE:

In case there is an issue with umi.js you can try adding the needed polyfills yourself (e.g. here is one for Proxy https://github.com/GoogleChrome/proxy-polyfill)
