node.js - 如何在Node.js中处理POST数据？(How to process POST data in Node.js?)

Question

How do you extract form data ( form[method="post"] ) and file uploads sent from the HTTP POST method in Node.js ?

(如何提取Node.js中 HTTP POST方法发送的表单数据（ form[method="post"] ）和文件上传？)

I've read the documentation, googled and found nothing.

(我已经阅读了文档，谷歌搜索并没有发现任何东西。)

function (request, response) {
    //request.post????
}

Is there a library or a hack?

You can use the querystring module:

(您可以使用querystring模块：)

var qs = require('querystring');

function (request, response) {
    if (request.method == 'POST') {
        var body = '';

        request.on('data', function (data) {
            body += data;

            // Too much POST data, kill the connection!
            // 1e6 === 1 * Math.pow(10, 6) === 1 * 1000000 ~~~ 1MB
            if (body.length > 1e6)
                request.connection.destroy();
        });

        request.on('end', function () {
            var post = qs.parse(body);
            // use post['blah'], etc.
        });
    }
}

Now, for example, if you have an input field with name age , you could access it using the variable post :

(现在，例如，如果您有一个名为age的input字段，则可以使用变量post访问：)

console.log(post.age);
