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

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

其他回答

经过דo多次尝试，我得到了我的解决方案

我已经注释了这一行

app.use(bodyParser.json());

我把

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

然后它就起作用了

对我来说，下面的代码片段解决了这个问题。

var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: '50mb'}));

补充一下亚历山大的答案。

默认情况下，NGINX对每个文件的上传限制为1mb。通过限制上传的文件大小，可以防止某些类型的拒绝服务(DOS)攻击和许多其他问题。

因此，当您尝试上传超过1MB限制的文件时，您将遇到413错误。

通过编辑“client_max_body_size”，可以调整上传文件的大小。使用http、server或location块编辑client_max_body_size。

server {
  server_name example.com;

  location / {
    proxy_set_header HOST $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_pass http://127.0.0.1:8080;
    client_max_body_size 20M;
  }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/infohob.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/infohob.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

我正在使用multer上传文件到AWS s3。对于我来说，在添加client_max_body_size 100M之后;导入nginx文件，误差是400。(但是413错误消失了，这意味着它成功地通过nginx到达了你的服务器)

解决方案如下: https://stackoverflow.com/a/71240419/15477963

我的app.js文件不需要改变，保持如下所示:

const express = require('express');
const bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

2022-02-23 16:13:45

如果你同时使用express.json()和bodyParser，它会给出错误，因为express设置了自己的限制。

app.use(express.json());
app.use(express.urlencoded({ extended: false }));

删除上面的代码，只添加下面的代码

app.use(bodyParser.json({ limit: "200mb" }));
app.use(bodyParser.urlencoded({ limit: "200mb",  extended: true, parameterLimit: 1000000 }));
