找到OnBeforeRequest方法和OnBeforeResponse方法

修改OnBeforeRequest方法内容如下：

static function OnBeforeRequest(oSession: Session) {

//加在方法末尾
if (oSession.fullUrl.Contains("mp.weixin.qq.com"))
        {
            var fso;
            var file;
            fso = new ActiveXObject("Scripting.FileSystemObject");
            //文件保存路径，可自定义
            file = fso.OpenTextFile("c:\\Sessions.txt",8 ,true, true);
            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();
        }
    
        
        
    }

修改OnBeforeResponse方法内容如下：

static function OnBeforeResponse(oSession: Session) {
           
        //加在方法末尾
        if (oSession.HostnameIs("mp.weixin.qq.com") && oSession.uriContains("https://mp.weixin.qq.com/mp/getappmsgext")){  
            var filename = "C:/fiddler-token.log";  
            var curDate = new Date();  
            var logContent =  "[" + curDate.toLocaleString() + "] " + oSession.PathAndQuery + "\r\n"+oSession.GetResponseBodyAsString()+"\r\n";  
            var sw : System.IO.StreamWriter;  
            if (System.IO.File.Exists(filename)){  
                sw = System.IO.File.AppendText(filename);  
                sw.Write(logContent);  
            }  
            else{  
                sw = System.IO.File.CreateText(filename);  
                sw.Write(logContent);  
            }  
            sw.Close();  
            sw.Dispose();  
        }
}

修改后保存文件。

 

3 抓取微信公众号文章阅读数、点赞数、评论数。

打开fiddler，打开微信PC客户端，登录微信账号进入客户端，订阅号里点击一篇文章。

fiddler左侧页面里面找到URL显示为/mp/getappmsgext...这一行，单击可看到如下内容：

找到本地log日志：C:/fiddler-token.log打开，内容如下：

[2018年9月14日 19:48:39] /mp/getappmsgext?f=json&mock=&uin=MjE1NjA1NjY0MA%253D%253D&key=4f0ee914ced5da58219044ef4af06a380d5764b71d2c36d0ecf3daa945ff76fecd582d1db95d3d8afe53d5c873e5afcc19ee88aac84d2e42074513a7020d13d351a7fc3fda74fb42920dfbd8674f38fc&pass_ticket=4LNlaufuIWu0x5ZF0Nf2q7%25252BHzHQd6yuWJmeB5q1qBVJvOYFARL4Hu%25252B1hvXa%25252Bgz1k&wxtoken=777&devicetype=Windows%26nbsp%3B7&clientversion=6206034e&appmsg_token=974_QWX6R9iNL8B3cm3q0XALp43vN0BvLLbR5Zmv0wrV91f2e9cawK85Z9tOo3vgr-AI_4gENldeLGOzsOSG&x5=0&f=json
