节点js中的实体太大(Express.js版本是4.16.1)

经过这么多次尝试,我终于找到了解决办法

我评论过这句话

app.use(bodyParser.json());

我把 app.use(bodyParser.json({limit: '50mb'}))

在主js文件中添加此参数作为中间软件

var express = require('express'); 
var app = express();
app.use(express.json({limit: 1024102420}));
app.use( bodyParser.json({parameterLimit: 50000,limit:1024102420,type:'application/json'}) );     // to support JSON-encoded bodies
app.use(bodyParser.urlencoded({parameterLimit: 50000, limit: 1024102420,    // to support URL-encoded bodies
  extended: true
  }));
