fiddler插件开发-DouYinCapture

文集移动端爬虫

前言

前面几篇文章介绍了app的自动化，但是光这样只是去掉人工操作，app运行时的请求并没有抓下来。下面介绍如何通过代理实现数据的抓取 — DouYinCapture。
介绍

DouYinCapture是fiddler的最基础最简单的一个插件即实现了IFiddlerExtension, IAutoTamper, IAutoTamper2接口的dll类库，只需要将这个dll文件加入到fiddler/scripts/下即能加载插件并按照我们的意愿过滤请求
部分代码

public class Douyin : IFiddlerExtension, IAutoTamper, IAutoTamper2
{
private static IModel channel;
private void sendTask(byte[] bs, string key)
{
channel.BasicPublish(exchange: "DouYin",
routingKey: key,
basicProperties: null,
body: bs);
FiddlerApplication.Log.LogString("rabbitmq: send successfully");

}
//private static FileStream fs = new FileStream("I:\fiddlerlog\response\douyin.txt", FileMode.Append, FileAccess.Write);

public void AutoTamperResponseAfter(Session oSession)
{
if (oSession.responseCode == 200)
{
sendTask(Encoding.UTF8.GetBytes(response), key);
}
}

public void OnBeforeUnload()
{
FiddlerApplication.Log.LogString("卸载抖音插件成功");
// fs.Close();
channel.Close();
channel.Dispose();
}

public void OnLoad()
{
FiddlerApplication.Log.LogString("加载抖音插件成功");
ConnectionFactory rbmqfactory = new ConnectionFactory()
{
HostName = "",
Port = 5672,
UserName = "",
Password = ""
};
IConnection con = rbmqfactory.CreateConnection();
channel = con.CreateModel();
FiddlerApplication.Log.LogString("连接RabbitMQ成功");
}
}
}</pre>

代码很简单，唯一需要注意的用了AssemblyInfo.cs的配置必须指定fiddler的最低版本，如果不指定，到时候fiddler既不报错也不能生效插件就很骚了。下面是我的fiddler的版本

[assembly: Fiddler.RequiredVersion("5.0.20182.28034")]
