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

对于快递~4.16.0,快递。Json与限制直接工作

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

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}))。

在我的例子中,从请求头中删除Content-type是有效的。

下面的方法对我很有效……只使用

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

就是这样。

以上都试过了,没有一个奏效。我们发现,即使我们使用像下面这样的方法,

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

只有第一个app.use(bodyParser());其中一行被定义,后两行被忽略。

参考:https://github.com/expressjs/body-parser/issues/176 >>见“dougwilson评论于2016年6月17日”

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

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 }));
