Nodejs修复[对象承诺]

问题描述

我想拿起tron钱包的影子。
当我想将其返回以使用expressjs在网页上显示时，它会打印[object Promise]

var express = require('express');
var router = express.Router();
const TronWeb = require('tronweb');
const tronWeb = new TronWeb({
        fullNode: 'https://api.trongrid.io',solidityNode: 'https://api.trongrid.io',eventServer: 'https://api.trongrid.io'
    }
)
/* GET home page. */
const userBalance = async function() {
  const getUserBalance = await tronWeb.trx.getBalance("TNBE5fs2tGTnaJhCvd1Qy2BQ1k2j7Yv5zs")
  const userBalance = getUserBalance;
   return userBalance;
};
router.get('/',function(req,res,next) {
  //userBalance();
  res.render('index',{
      title: 'Express',userBalance: userBalance(),});
});

module.exports = router;

解决方法

您应该写

router.get('/',async function(req,res,next) {
  const userBalance = await userBalance();
  res.render('index',{
      title: 'Express',userBalance: userBalance
  });
});
