使用请求模块时是否有结束事件?

我正在使用在npm上找到的请求模块,我想知道是否有可以绑定的结束事件。我问的原因是因为我要求一个JSON,如果我在得到响应后尝试直接使用JSON.parse,我会收到错误。代码看起来像这样。

var parseJSON = function(JSON, cb){

    var parsed = JSON.parse(JSON);
    cb(parsed);

};

request(url, function(error, response, body) {

    parseJSON(body, function(bodyObj){

        // do stuff with bodyObj...

    });
});

尝试这样做,会出现以下错误......

var parsed = JSON.parse(JSON);
                  ^

问题是你要覆盖全局JSON对象。

这样可以正常工作:

var parseJSON = function(MyJSON, cb){

    var parsed = JSON.parse(MyJSON);
    cb(parsed);

};
