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

在我的例子中，添加这些行是不够的:

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

我尝试在urlencoded函数上添加parameterLimit选项，正如文档所述，错误不再出现。

parameterLimit选项控制参数的最大数量 在url编码的数据中是允许的。如果请求包含更多 参数大于此值时，将返回一个413给客户端。 默认值为1000。

试试下面的代码:

var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: "50mb"}));
app.use(bodyParser.urlencoded({limit: "50mb", extended: true, parameterLimit:50000}));

其他回答

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}))。

为我工作:

配置nginx max file zise [https://patriciahillebrandt.com/nginx - 413 -请求-实体——太——large/] [1]

and

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

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
}));

对于快递~4.16.0，快递。Json与限制直接工作

app.use(express.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

}

参考:在NGINX限制文件上传大小
