错误:请求实体太大

我收到以下错误与快递:

POST /api/0.1/people 500 618ms

我用的是meanstack。我有以下使用语句在我的express.js

//Set Request Size Limit
app.use(express.limit(100000000));

在fiddler中，我可以看到内容长度头的值为:1078702

我想这是八位字节，这是1.0787兆字节。

我不知道为什么express不让我发布json数组，我之前在另一个express项目中发布，该项目没有使用平均堆栈项目结构。

当前回答

此问题在两种情况下发生:

请求体太大，服务器无法处理这么大的数据。这个就可以了

app.use(express.json({limit: '50mb'}));

2- req.cookies is too large. When testing different next.js applications on the same browser, each time each app was starting on a different port if there were running some apps. Same app might end up starting at port 3000-3005 range. That means if your app saves cookie, that cookie will be saved for each port. Let's say you started 5 different apps at localhost:3000, and each one saved a cookie. If you make a request, all the cookies will be attached to the request object, in this case you will not able to process even small size of post.body. Solution is you have to delete all the cookies

其他回答

我最近遇到了同样的问题，咆哮的解决方案对我来说很有效。

依赖: 快递>>版本:4.17.1 Body-parser >> version": 1.19.0

const express = require('express');
const bodyParser = require('body-parser');

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

为了理解: HTTP 431

HTTP 413负载过大响应状态码表示请求实体大于服务器定义的限制;服务器可能会关闭连接或返回一个Retry-After报头字段。

如果有人尝试了所有的答案，但还没有任何成功，并使用NGINX托管站点，将这一行添加到/etc/nginx/sites-available

client_max_body_size 100M; #100mb

更好的使用方法是，你可以指定文件大小的限制，如下所示:

app.use(bodyParser.json({limit: '10mb', extended: true}))
app.use(bodyParser.urlencoded({limit: '10mb', extended: true}))

您也可以在node-modules body-parser中更改默认设置，然后在lib文件夹中，有JSON和文本文件。然后改变这里的极限。实际上，如果你没有在给定的行中传递limit参数，这个条件就会通过 app.use (bodyParser。Json ({limit: '10mb'， extended: true}))。

对我来说，主要的技巧是

app.use(bodyParser.json({
  limit: '20mb'
}));

app.use(bodyParser.urlencoded({
  limit: '20mb',
  parameterLimit: 100000,
  extended: true 
}));

bodyParse。json第一 bodyParse。urlencoded第二

就我而言…setting parameterLimit:50000修复了这个问题

app.use( bodyParser.json({limit: '50mb'}) );
app.use(bodyParser.urlencoded({
  limit: '50mb',
  extended: true,
  parameterLimit:50000
}));
