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

在尝试了这篇文章中的一切之后，我都没有成功。但我找到了一个适合我的解决办法。我可以在不使用body解析器的情况下只使用express来解决它。它是这样的:

const express = require('express');    

const app = express();
app.use(express.json({limit: '25mb'}));
app.use(express.urlencoded({limit: '25mb', extended: true}));

不要忘记使用extended: true从控制台中删除已弃用的消息。

其他回答

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

我使用了另一种方法来解决这个问题。

例子:

multer = require('multer');

var uploading = multer({
  limits: {fileSize: 1000000, files:1},
});

exports.uploadpictureone = function(req, res) {
  cloudinary.uploader.upload(req.body.url, function(result) {
    res.send(result);
  });
};

module.exports = function(app) {
    app.route('/api/upload', uploading).all(uploadPolicy.isAllowed)
        .post(upload.uploadpictureone);
};

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}))。

只要加上这一行就能解决问题

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

还建议大家将整个图像发送到后端，然后转换它，而不是从前端发送数据

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 }));
