2 配置fiddler抓取规则

找到OnBeforeRequest方法和OnBeforeResponse方法
修改OnBeforeRequest方法内容如下：
static functionOnBeforeRequest(oSession: Session) {//加在方法末尾
if (oSession.fullUrl.Contains("mp."))
{varfso;varfile;
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 functionOnBeforeResponse(oSession: Session) {//加在方法末尾
if (oSession.HostnameIs("mp.") && oSession.uriContains("https://mp./mp/getappmsgext")){var filename = "C:/fiddler-token.log";var curDate = newDate();var logContent = "[" + curDate.toLocaleString() + "] " + oSession.PathAndQuery + "\r\n"+oSession.GetResponseBodyAsString()+"\r\n";varsw : 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。
