获取POST参数

var     url = require("url"),
        querystring = require("querystring");

module.exports = function(req, res, next){
    if (req.method == "POST") {
        var DATA = "";
        req.on("data", function(chunk){
            DATA += chunk;
        });
        req.on("end", function(){
            req["bodys"] = querystring.parse(DATA);
            console.log("POST", req.url, req["bodys"]);
            next();
        });
    } else next();
}
