python实现模拟器爬取抖音评论数据的示例代码

目标：

由于之前和朋友聊到抖音评论的爬虫，demo做出来之后一直没整理，最近时间充裕后，在这里做个笔记。
提示：大体思路 通过fiddle + app模拟器进行抖音抓包，使用python进行数据整理

安装需要的工具：

python3 下载
fiddle 安装及配置
手机模拟器下载

抖音部分：

模拟器下载好之后, 打开模拟器
在应用市场下载抖音

对抖音进行fiddle配置，配置成功后就可以当手机一样使用了

一、工具配置及抓包：

我们随便打开一个视频之后，fiddle就会刷新新的数据包

在json中找到视频地址：

二、fiddler中添加下载视频评论代码

在fiddler中添加下载视频代码：注意两点：
（1）get后面的路径要随时看进行更换
（2）下载的路径要在fiddler下面自己新建

 if (m_Hide304s && oSession.responseCode == 304) {
      oSession["ui-hide"] = "true";
    }
    
    if (oSession.uriContains("https://aweme.snssdk.com/aweme/v1/general/search/single/")){
      var strBody=oSession.GetResponseBodyAsString();
      var sps = oSession.PathAndQuery.slice(-58,);
      //FiddlerObject.alert(sps)
      var timestamp=new Date().getTime();
      var filename = "D:\抖音评论资料" + "/" + sps + timestamp + ".json";
      var curDate = new Date(); 
      var sw : System.IO.StreamWriter; 
      if (System.IO.File.Exists(filename)){ 
        sw = System.IO.File.AppendText(filename); 
        sw.Write(strBody); 
      } 
      else{ 
        sw = System.IO.File.CreateText(filename); 
        sw.Write(strBody); 
      } 
      sw.Close(); 
      sw.Dispose(); 

此段代码放到fiddler中的script的response中，如下图：添加好之后别忘记保存！！

三、python执行代码pycharm新建py文件

程序执行代码：

import os
import json
import time
import requests
import re
import csv

  def __init__(self):
    pass
    self.url1 = 'https://aweme.snssdk.com/aweme/v2/comment/list/?aweme_id=6885929189950737676&cursor=0&count=20&address_book_access=1&gps_access=1&forward_page_type=1&channel_id=0&city=310000&hotsoon_filtered_count=0&hotsoon_has_more=0&follower_count=0&is_familiar=0&page_source=0&os_api=25&device_type=VOG-AL00&ssmix=a&manifest_version_code=110301&dpi=240&uuid=868594157367551&app_name=aweme&version_name=11.3.0&ts=1603350069&cpu_support64=false&app_type=normal&ac=wifi&host_abi=armeabi-v7a&channel=aweGW&update_version_code=11309900&_rticket=1603350070959&device_platform=android&iid=1758845207590062&version_code=110300&mac_address=b0%3Ac4%3A2d%3Ad0%3Aed%3A38&cdid=7974198e-c4c0-49c2-bfaa-43686052706e&openudid=d0c6cffa7067bedd&device_id=844047245117672&resolution=720*1280&device_brand=HUAWEI&language=zh&os_version=7.1.2&aid=1128&mcc_mnc=46000'

          meta['comment_count'] = ''
          meta['share_count'] = ''
          meta['share_url'] = ''

        if meta['u_name'] == '':
          try:
            meta['u_name'] = con['aweme_info']['music']['owner_handle']
          except:
            meta['u_name'] = ''
        if meta['title'] == '':
          pass
        else:
          lists.append(meta)
          # print(meta)
    return lists

  def save_data(self, meta):
    header = ['share_url', 'title', 'author_name', 'u_name', 'create_time', 'digg_count', 'comment_count', 'share_count']
    print(meta)
    with open('test.csv', 'a', newline='', encoding='utf-8-sig') as f:
      writer = csv.DictWriter(f, fieldnames=header)
      writer.writeheader() # 写入列名
      writer.writerows(meta)

  def run(self):
    meta = self.parse()
    self.save_data(meta)

if __name__ == '__main__':
  douyin = Douyin()
  douyin.run()

运行代码后在代码执行目录下会生成一个excel

ps：抖音不会一次性返回整个评论数据包，每次往下滑动评论区会多出26条评论数据，我们就可以利用模拟器进行滑动操作。

点击 更多>鼠标宏

点击录屏之后，用鼠标往下滑动一次页面

点击停止，就会将你刚才的操作保存下来

点击设置 可以对刚才的操作进行循环播放，从而达到自动刷新评论区。
