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

我也面临着这个问题，我犯了一个愚蠢的错误，重复了app.use(bodyParser.json())，如下所示:

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

通过删除app.use(bodyParser.json())，解决了这个问题。

其他回答

对于那些在IIS下在Azure中启动NodeJS应用程序的人，不要忘记修改web。配置Azure应用服务IIS的“maxRequestLength”设置

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
}));

以下代码解决了我的问题:

var bodyParser = require('body-parser');
var urlencodedParser = bodyParser.urlencoded({ extended: false, limit: '5mb' });

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);
};
