POST数据太大,出现了413错误,错误描述 request entity too large

原因:

使用了koa-body,koa-bodyparser,从它们的README看,接收的参数有默认大小

koa-body

- `jsonLimit` **{String|Integer}** The byte (if integer) limit of the JSON body, default `1mb`

- `formLimit` **{String|Integer}** The byte (if integer) limit of the form body, default `56kb`

- `textLimit` **{String|Integer}** The byte (if integer) limit of the text body, default `56kb`

koa-bodyparser

* **formLimit**: limit of the `urlencoded` body. If the body ends up being larger than this limit, a 413 error code is returned. Default is `56kb`.

* **jsonLimit**: limit of the `json` body. Default is `1mb`.

* **textLimit**: limit of the `text` body. Default is `1mb`.

解决的方法


const koaBody = require('koa-body'); const bodyParser = require('koa-bodyparser')  app.use(koaBody({     multipart: true,     formLimit:"10mb",     jsonLimit:"10mb" })); app.use(bodyParser({     formLimit:"10mb",     jsonLimit:"10mb" }));
