微信token验证失败？

Question

微信配置的token验证老是失败不知道原因？
配置页面：

token.js页面

/** 
 * Created by tangxuelong on 15-10-16. 
 * validateToken 
 * 此文件只用于TOKEN验证 
 */  
var http = require('http');//内置http modoule  
var config = require('./http.config')//配置module  
var api = require('wechat-api');//npm wx  
var url = require("url");  
var crypto = require("crypto");  
  
//微信接口的哈希加密方法  
function sha1(str) {  
    var md5sum = crypto.createHash("sha1");  
    md5sum.update(str);  
    str = md5sum.digest("hex");  
    return str;  
}  
//微信路径token验证  
function validate_token(req,res){  
    //获取请求的qurey排序以后加密  
    var query = url.parse(req.url, true).query;  
    var signature = query.signature;  
    var echostr = query.echostr;  
    var timestamp = query['timestamp'];  
    var nonce = query.nonce;  
    var oriArray = new Array();  
    oriArray[0] = nonce;  
    oriArray[1] = timestamp;  
    oriArray[2] = "这里填写了上面配置中的token";  
    oriArray.sort();  
    var original = oriArray.join('');  
    var scyptoString = sha1(original);  
    if (signature == scyptoString) {  
        res.end(echostr);  
        console.log("Confirm and send echo back");  
    } else {  
        res.end("false");  
        console.log("Failed!");  
    }  
}  
//创建http服务器  
http.createServer(function(req,res){  
    validate_token(req,res);  
}).listen(config.port, config.http_ip);  
console.log('http server is running');
