node.js - Express/NodeJS : stderr: Error: request entity too large

Question

有以下代码:

var url             = require('url');
var proxy           = require('express-http-proxy');
var localConfig     = require('./config.js');
var frontendRuntime = require('frontend-runtime')(localConfig);
var config          = frontendRuntime.config;
var app             = require('./lib/utils/devServer.js');

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

app.use(bodyParser.json({limit: 10 * 1024 * 1024}));
app.use(bodyParser.raw({limit: 10 * 1024 * 1024}));
app.use(bodyParser.text({limit: 10 * 1024 * 1024}));
app.use(bodyParser.urlencoded({limit: 10 * 1024 * 1024, extended: true}));

app.use('/some-url', proxy(config.apiEndpointHost, {
  forwardPath: function(req, res) {
    return '/api2' + url.parse(req.url).path;
  }
}));

app.listen(config.portProxy);
console.log('Server started');

正如你所看到的，我为 bodyParser 传递了“limit”参数(我想上传文件)，但它不起作用 - 当我尝试上传 1.5 Mb 大小的图像时，我收到错误:“stderr:错误: 请求的实体太大”。我该如何修复它？谢谢!

根据this issue你不需要 bodyParser

app.use('/some-url', proxy(config.apiEndpointHost, {
      limit: 10 * 1024 * 1024,
      forwardPath: function(req, res) {
        return '/api2' + url.parse(req.url).path;
      }
    }));
