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

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。

其他回答

在我的例子中，问题出在Nginx配置上。为了解决这个问题，我必须编辑文件:/etc/nginx/nginx.conf，并在服务器块中添加这一行:

client_max_body_size 5M;

重新启动Nginx，问题就消失了

sudo systemctl restart nginx

我也有同样的问题

使用快捷4.+ 我的代码看起来像这样，经过两天的广泛测试，它工作得很好。

var url         = require('url'),
    homePath    = __dirname + '/../',
    apiV1       = require(homePath + 'api/v1/start'),
    bodyParser  = require('body-parser').json({limit:'100mb'});

module.exports = function(app){
    app.get('/', function (req, res) {
        res.render( homePath + 'public/template/index');
    });

    app.get('/api/v1/', function (req, res) {
        var query = url.parse(req.url).query;
        if ( !query ) {
            res.redirect('/');
        }
        apiV1( 'GET', query, function (response) {
            res.json(response);
        });
    });

    app.get('*', function (req,res) {
        res.redirect('/');
    });

    app.post('/api/v1/', bodyParser, function (req, res) {
        if ( !req.body ) {
            res.json({
                status: 'error',
                response: 'No data to parse'
            });
        }
        apiV1( 'POST', req.body, function (response) {
            res.json(response);
        });
    });
};

如果有人尝试了所有的答案，但还没有任何成功，并使用NGINX托管站点，将这一行添加到/etc/nginx/sites-available

client_max_body_size 100M; #100mb

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
