適用場景：
- 你是前端開發人員，要開發一個小模塊，需要用到線上的環境（賬號、數據、跨域等），但你又沒有權限往線上傳文件
- 你是移動測試人員，需要將一組接口的返回結果替換為另一組，最簡單的辦法就是使用Fiddler修改接口返回結果
實現腳本代碼：

說明：
將OnBeforeRequestCallback方法中的hUrl替換為要劫持的URL路徑（可以是部分），將D:\\MyWeb替換為本地文件夾路徑。
以代碼中路徑為例：將來訪問http://www.shouxiner.com/MyHome/index.html時，就會轉向訪問D:\MyWeb\index.html文件里的內容
?
使用方法：
下載FiddlerScript插件并安裝，將以上代碼粘貼入FiddlerScript保存即可
