前言：

為了獲取一定高級(jí)操作，如：微信模板消息(xiao,xin)推送，把消息推送給用戶(hù)，或者是獲取用戶(hù)授權(quán)信息都需要用到access token，有效期為兩個(gè)小時(shí)？

過(guò)了兩個(gè)小時(shí)怎么辦？重新獲取，來(lái)，代碼擼起走，啥女朋友沒(méi)有？

獲取小程序?qū)?yīng)的access token

          
            def get_wx_token():
    url = "https://api.weixin.qq.com/cgi-bin/token?"
    try:
        respone = requests.get(url, params=payload, timeout=50)
        access_token = respone.json().get("access_token")
        res = respone.json()
        res["time"] = stamp
        print(u'token過(guò)期，重新寫(xiě)入文件的內(nèi)容>>>', res)
        with open(token_file, "w+") as f:
            f.write(json.dumps(res))
        return access_token
    except Exception as e:
        msg = traceback.format_exc()
        print('get token error', msg)
        return

          
        

并判斷是否過(guò)期

def get_access_token():

          
            try:
    with open(token_file, "r") as f:
        content = f.read()
        data_dict = content
        # 如果緩存內(nèi)容為空，直接重新獲取token
        if (content == ''):
            print("token文件為空，重新獲取并寫(xiě)入文件")
            result = get_wx_token()
            return result
        else:
            data_dict = re.sub('\'', '\"', data_dict)
            token_time = int(json.loads(data_dict)['time'])
            if (stamp - token_time) > 7100:
                # print("token過(guò)期，重新獲取并寫(xiě)入文件")
                get_wx_token()
            else:
                return  json.loads(data_dict)['access_token']
except Exception as e:
    msg = traceback.format_exc()
    print("access token express time", msg)
    



          
        

根據(jù)access token 獲取模板列表

          
            def get_templates_list(access_token):
    url = "https://api.weixin.qq.com/cgi-bin/wxopen/template/list?access_token={}".format(access_token)
    data = {
      "offset": 0,
      "count": 20
    }
    r = requests.post(url,data=json.dumps(data)).json()
    tpl_list = r.get('list')
    for tpl in tpl_list:
        print(tpl)
    # print(r.get('list'))
    
    

          
        

返回?cái)?shù)據(jù)示例

          
            {
  "errcode": 0,
  "errmsg": "ok",
  "list": [

      "example": "購(gòu)買(mǎi)地點(diǎn)：TIT造艦廠\n購(gòu)買(mǎi)時(shí)間：2016年6月6日\(chéng)n物品名稱(chēng)：咖啡\n"
    }
  ]
}
