Question

当我尝试以某种方式启动时，我正在使用 TronWeb 和 TronGrid，我看到随机完成 index.js，有时它完成时出错。状态码 502..

index.js

const TronGrid = require("trongrid");
const TronWeb = require("tronweb");

const tronWeb = new TronWeb({
    fullHost: 'https://api.shasta.trongrid.io'
});

const tronGrid = new TronGrid(tronWeb);
const address = "TE5KZD*******EdwZYJqxWjqjAovvEeGu";

async function  getBalance(adr)  {
    const balance = await tronWeb.trx.getBalance(adr);
    console.log("balance:", balance/1000000);
}
getBalance(address);

package.json

{
  "name": "trontest",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "trongrid": "^1.2.6",
    "tronweb": "^3.2.6"
  }
}

对于正确完成的每个请求，我应该怎么做？谢谢！

Tronweb 和 Trongrid 错误：请求失败，状态码为 502
