我使用 MERN 堆栈应用程序通过前端将我的 java 合约部署到 Mastery 网络,并在编译时遇到以下错误:

Module not found: Error: Can't resolve 'fs' in '/home/parina/Documents/aion-counter/node_modules/aion-web3-eth/src'

为了纠正这个问题,我添加了

node: {
fs: "empty"
},

到我的 webpack.config.js 文件。在此之后,我成功地编译了我的项目并启动了服务器,但是在浏览器中打开项目时,合约没有部署,我在控制台中收到以下错误:

TypeError: fs.readFileSync is not a function at Contract.deploy (index.js?60f4:244) at _callee$ (Main.js?1523:40) at tryCatch (runtime.js?280d:65) at Generator.invoke [as _invoke] (runtime.js?280d:303) at Generator.prototype.<computed> [as next] (runtime.js?280d:117) at step (Main.js?1523:9) at eval (Main.js?1523:9) at new Promise (<anonymous>) at eval (Main.js?1523:9) at deploy (Main.js?1523:19)

在各种论坛上搜索后,我发现 fs 不应该用在前端,有人建议我使用它的替代品。但它在这里被 Aion 节点模块使用,而不是直接使用,因此我似乎无法找到绕过它的方法。

最佳答案

正如您提到的,因为 fs 是一个服务器端模块,文件可以上传(通过 react 或任何客户端模块)到服务器并在服务器端执行并将响应返回给客户端。

所以我建议获取 jar 的编码字节码以及部署参数,并将交易数据字段设置为编码数据。

例如,假设您正在部署计数器示例合约 (https://docs.aion.network/docs/deploy-a-contract#section-example-script):
