我有一个非常简单的脚本来测试读取 URL 参数。该脚本在运行节点的 2 台计算机上正确执行，但运行节点的第三台计算机失败。这是脚本：

var http = require('http');
var URL = require('url');
var host = '127.0.0.1';
var port = 8181;

// Is called when a request comes in
handler = function(req, res) {
    var url_parts = URL.parse(req.url);
            console.log("url_parts = "+url_parts);

    var query = url_parts.query;
        console.log("xxx query = "+query);

    var qArray = parseGetVars(query); 
    var body = {
        "errorCode": "0","errorMessage":"","params" : qArray
    };

    // sets content-type of the responce
    res.writeHead(200, {
        'Content-Type' : 'application/json'
    });

    // terminates the response, and passes back the json as text.
    res.end(JSON.stringify(body));


};


var parseGetVars = function(thisString) {
    var getVars = new Array();
    var qString = thisString;
    console.log("qString = "+qString);
    if(qString!=''){
        var pairs = qString.split(/\&/);
        for (var i in pairs) {
            var nameVal = pairs[i].split(/\=/);
            getVars[nameVal[0]] = nameVal[1];
        } 
    }
    console.log("getVars = "+getVars);

    return getVars;
}



http.createServer(handler).listen(port, host);

console.log('Server running at http://' + host + ':' + port + '/');

调用脚本如下： http ://mydomain.com:8181/?d=1&p=2

正如我所说，此脚本在 2 台计算机上运行良好（均运行 v0.10.7）。第三次我在控制台中收到此错误：

Server running at http://localhost:8181/
url_parts = [object Object]
xxx query = d=1&p=2
qString = d=1&p=2
getVars = 
url_parts = [object Object]
xxx query = null
qString = null

/Users/me/Sites/node/params.js:36
        var pairs = qString.split(/\&/);
                            ^
TypeError: Cannot call method 'split' of null

任何想法都非常感谢
