他们有什么办法增加对表单数据的请求限制？

Answer 1

我认为以下可能对您有帮助

var app = express();
app.use(bodyParser.urlencoded({limit: '50mb', extended: false}));
app.use(bodyParser.json({limit: '50mb'}));

Answer 2

使用Body Parser NPM： https : //www.npmjs.com/package/body-parser

var bodyParser = require('body-parser');

 app.use(bodyParser.urlencoded({
  extended: true,
  limit: '50mb',
  parameterLimit: 100000
  }))

 app.use(bodyParser.json({
  limit: '50mb',
  parameterLimit: 100000
 }))
