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

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”

下面的设置对我很有效

表达4.16.1

app.use(bodyParser.json({ limit: '50mb' }))
app.use(bodyParser.urlencoded({
  limit: '50mb',
  extended: false,
}))

恩金克斯

client_max_body_size 50m;
client_body_temp_path /data/temp;

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

我不认为这是快速全球大小限制,但特别是连接。Json中间件限制。当您使用express.bodyParser()并且不提供限制选项时,默认为1MB。

Try:

app.post('/api/0.1/people', express.bodyParser({limit: '5mb'}), yourHandler);

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 }));
