Fiddler自定义配置

Fiddler

配置

配置代理 ： Tools -> Options

一、Fiddler添加查看请求类型列

菜单 Rules > Customize Rules

在CustomRules.js里找到static function Main()添加如下一段脚本

   // The Main() function runs everytime your FiddlerScript compiles
   static function Main() {
       var today: Date = new Date();
       FiddlerObject.StatusText = " CustomRules.js was loaded at: " + today;

       // Uncomment to add a "Server" column containing the response "Server" header, if present
       // UI.lvSessions.AddBoundColumn("Server", 50, "@response.server");
       // 增加菜单 Method
	FiddlerObject.UI.lvSessions.AddBoundColumn("Method",60,getHTTPMethod );


       // Uncomment to add a global hotkey (Win+G) that invokes the ExecAction method below...
       // UI.RegisterCustomHotkey(HotkeyModifiers.Windows, Keys.G, "screenshot"); 
   }
	
   //获取Method
static function getHTTPMethod(oS: Session){
	if (null != oS.oRequest) return oS.oRequest.headers.HTTPMethod; else return String.Empty;
}

二、Filters的使用

三、请求重放

三、请求转发

场景：将请求转发到本地

from: regex:(?inx)^https://172.16.103.12/drama-api/(?<name>.+)$

to: http://192.168.5.203:8080/drama-api/${name}

四、请求拦截与修改

场景：需要在请求发起前作出修改与放行

Rules -> Automatic Breakpoints 可以选择

- Before Request
- After Response

示例一：录入脚本获取数据，写入文件

  1. 定位到方法：OnBeforeResponse
  2. 使用Fildder代理访问：https://www.douyin.com/channel/300203

static function OnBeforeResponse(oSession: Session) {
    if (m_Hide304s && oSession.responseCode == 304) {
        oSession["ui-hide"] = "true";
    }
    if(oSession.fullUrl.Contains("/aweme/v1/web/channel/feed/")){
        //保存文件路径只能是英文
        var path = "D:\\douyin\\"
        try{
            //对返回数据解码
            oSession.utilDecodeResponse();
            //获取返回内容
            var body = oSession.GetResponseBodyAsString();
            //将文本转换为json类型
            var responseJSON = Fiddler.WebFormats.JSON.JsonDecode(body);
            FiddlerObject.log("=======================这一页的抖音视频信息=====================")
            //判断是否为JSON
            if((responseJSON.JSONObject=='System.Collections.ArrayList' || responseJSON.JSONObject=='System.Collections.Hashtable')&&body!='[]'&&body!='{}'){
                for(var list in responseJSON.JSONObject["aweme_list"]){
                    //作者名字
                    var zuozhe = list["author"]["nickname"]
                    //点赞数
                    var dzs = list["statistics"]["digg_count"]
                    //视频标题信息
                    var title = list["desc"]
                    //获取视频下载地址
                    var videoUrl = list["video"]["play_addr"]["url_list"][1]
                    //获取主页链接
                    //var zhuye = "https://www.douyin.com/user/"+list["author"]["sec_uid"]
                    FiddlerObject.log("视频标题:" + title + "|作者：" + zuozhe + "|点赞数：" + dzs)
                    FiddlerObject.log("视频下载地址:" + videoUrl)
                    //保存为文本
                    saveTextToLocal(path, "视频标题:" + title + "|作者：" + zuozhe + "|点赞数：" + dzs)
                    saveTextToLocal(path, "视频下载地址:" + videoUrl)
                }
            }
            FiddlerObject.log("=======================这一页的抖音视频信息=====================")
        }catch (e){
            FiddlerObject.log("代码出现错误，错误原因:"+e)
        }
    }
}
    
static function saveTextToLocal(textpath, body) {
    var fso;
    var file;
    try {
        //判断是否有这个文本，没有就创建
        if (!System.IO.Directory.Exists(textpath)) {
            System.IO.Directory.CreateDirectory(textpath);
        }
        fso = new ActiveXObject("Scripting.FileSystemObject");
        //参数2为直接替换文本，8为追加
        file = fso.OpenTextFile(textpath + "douyin.txt", 8, true, true);
        //写入文本
        file.writeLine(body);
        //关闭文件句柄
        file.close();
        return true;
    } catch (e) {
        if (file != null) {
            file.close();
        }
        FiddlerObject.log("保存文件出错,错误原因:" + e);
        return false;

    }
}

效果：
