在Electron使用加密
问题说明
我正在尝试在电子项目中使用加密货币.我在DevTool控制台中收到未捕获的TypeError:crypto.randomBytes不是函数"错误.这就是我所做的:
I am trying to use crypto in my electron project. I am getting "Uncaught TypeError: crypto.randomBytes is not a function" error in the DevTool console. This is what I did:
- 按照此处 创建的示例电子项目
- 添加了
crypto = require('crypto')作为preload.js的第一行 - 添加了
console.log(crypto.randomBytes(4))作为renderer.js的第一行
- Created a sample electron project as mentioned here
- Added
crypto = require('crypto')as the first line in preload.js - Added
console.log(crypto.randomBytes(4))as the first line in renderer.js
我收到上面提到的错误.谷歌搜索没有提出任何相关答案.
I get the error mentioned above. Googling didn't bring up any relevant answers.
我该如何进行?
预先感谢
正确答案
Chromium已包含名为"crypto"的全局变量，因此您无法重新分配它，而应更改全局变量f.e的名称
Chromium already contains global, that called "crypto", so you cannot reassign it and should change name of your global variable, f.e
nodeCrypto = require('crypto') // or window.nodeCrypto = require('crypto')
，然后在渲染器中
console.log(nodeCrypto.randomBytes(4))
或者您可以在 BrowserWindow 参数的 webPreferences 块中添加 nodeIntegration:true ，并在某些模块中直接使用renderer中的require(如果您不想将全局文件放入预加载文件中.
Or you can add nodeIntegration:true in webPreferences block in BrowserWindow params, and use require directly from renderer in some of yours modules (if you don't want to put in global in preload file).
const crypto = require('crypto'); // or const crypto = window.require('crypto')
