最近有幾個同學讓我們幫忙抓取今日頭條app的數據，有的同學需要頭條app?的廣告數據，有的同學需要電商資訊的數據，之前已經在博客中發布過頭條app的廣告數據，這里我就來用電商的數據來給大家講解。

1.想要抓到app的數據，就需要先抓到相應的接口，這里給大家推薦使用Charles工具來抓接口。具體怎么抓取接口的方法這里就不介紹了，大家可以去百度，我這里直接給出接口。

2.拿到接口了之后，我們就可以使用python去獲取到數據了

response = requests.get(url, headers=self.getHeader(), verify=False)

使用這行代碼，將抓取到額url傳入，頭部我們可以使用

header = {"Host": "is.snssdk.com","Accept-Language": "zh-Hans;q=1","tt-request-time": str(int(time.time() * 1000)),"Connection": "keep-alive","Accept-Encoding": "gzip,deflate","Cookie": "CNZZDATA1272189606=1385639719-1525687011-%7C1525692411;alert_coverage=76;install_id=31781370987;ttreq=1$b79c6e66ea460b1579579c027e8073593305644e;odin_tt = 4c07858cc8b75143c593d0a99a04aa8fcf10136c3dca9badd9c31a2aa9cc415022834c64d7f52952d9290e3028876735;UM_distinctid = 1633a13d9fd41b-0910970a30f79a8-12485712-3d10d-1633a13d9fe84a;_ga=GA1.2.555016291.1525687770;_gid=GA1.2.96631484.1525687770;qh[360] = 1;__tea_sdk__ssid=957b8ce1-d5b3-4010-bd9c-bfec73bdf526;__tea_sdk__user_unique_id=6552731409432937992;tt_webid=6552731409432937992","X-SS-Cookie": "CNZZDATA1272189606=1385639719-1525687011-%7C1525692411;alert_coverage = 76;install_id=31781370987;ttreq=1$b79c6e66ea460b1579579c027e8073593305644e;odin_tt=4c07858cc8b75143c593d0a99a04aa8fcf10136c3dca9badd9c31a2aa9cc415022834c64d7f52952d9290e3028876735;UM_distinctid=1633a13d9fd41b-0910970a30f79a8-12485712-3d10d-1633a13d9fe84a;_ga=GA1.2.555016291.1525687770;_gid=GA1.2.96631484.1525687770;qh[360]=1;__tea_sdk__ssid=957b8ce1-d5b3-4010-bd9c-bfec73bdf526;__tea_sdk__user_unique_id=6552731409432937992;tt_webid=6552731409432937992","User-Agent": "News/6.6.5(iPhone;iOS10.2;Scale/2.00)","Accept": "*/*"}

這樣我們就可以獲取電商類目的數據了，我們運行項目看結果，頭條給我們返回的數據，這里是我使用json工具格式化，其中打他就是我們想要的電商類目的數據，其中content字段就是每條數據的詳細信息。

這里我們就需要取出content里面的詳細數據，代碼如下：

json_list = (json.loads(jsonStr))["data"] for json_str in json_list:content = json.loads(json_str["content"])self.savaDataInfo(content)

每條數據的信息量是很大的，我們取出需要的數據保存數據庫即可，保存數據庫代碼如下

def savaDataInfo(self, content):DataInfo.title = content["title"]DataInfo.type = 1DataInfo.channel = "jinritoutiao"if "download_url" in content["raw_ad_data"]:DataInfo.appdownload = content["raw_ad_data"]["download_url"]self.saveBitmapUrlOrPath(content)DataInfo.device_type = "ios"DataInfo.app_name = content["source"]MySqlManager().insert_inspection_list(3)

插入數據庫：

def insert_inspection_list(self, table_id):print(str(DataInfo.pic_list))print(str(DataInfo.pic_path))sql = "INSERT INTO " + self.getTableName(table_id) + "(title,app_download,time,channel,type,content,gif,video,source_type,pic_list,pic_path,device_type,material_size,app_name,created_at,updated_at)" \" VALUES ('%s','%s','%s','%s',%d,'%s','%s','%s',%d,'%s','%s','%s','%s','%s','%s','%s')" \% (DataInfo.title, DataInfo.app_download, DataInfo.time, DataInfo.channel, DataInfo.type,DataInfo.content, json.dumps(DataInfo.gif), json.dumps(DataInfo.video), DataInfo.source_type, json.dumps(DataInfo.pic_list),json.dumps(DataInfo.pic_path), DataInfo.device_type,DataInfo.material_size,DataInfo.app_name, self.getCurrentTime(), self.getCurrentTime())cursor = self.conn.cursor()cursor.execute(sql)self.conn.commit()

?

到這里基本就完成了如何獲取今日頭條app的電商數據了
