2.在OnBeforeRequest方法里添加如下代碼修改請求的host ，將請求的host為www.baidu.com的請求轉發(fā)至www.taobao.com

var origin_host="www.baidu.com";
var replace_host="www.taobao.com";
if(oSession.host==origin_host){
    oSession.fullUrl = oSession.fullUrl.Replace(origin_host,replace_host);
}

3.在OnBeforeRequest方法里添加如下代碼，將含有www.baidu.com的請求數據保存至D:\http\Interface.txt文件里

if (oSession.fullUrl.Contains("www.baidu.com"))
        {
            var fso;
            var file;
            fso = new ActiveXObject("Scripting.FileSystemObject");
            
                file = fso.OpenTextFile("D:\\http\\Interface.txt",8 ,true, -2);
                file.writeLine("Request url:" + oSession.url);
                file.writeLine("Request header:" + "\n" + oSession.oRequest.headers);
                file.writeLine("Request body:" + oSession.GetRequestBodyAsString());
                file.writeLine("\n");
                file.close();
    
        }
