前言:
为了获取一定高级操作,如:微信模板消息(xiao,xin)推送,把消息推送给用户,或者是获取用户授权信息都需要用到access token,有效期为两个小时?
过了两个小时怎么办?重新获取,来,代码撸起走,啥女朋友没有?
获取小程序对应的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过期,重新写入文件的内容>>>', 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
并判断是否过期
def get_access_token():
try:
with open(token_file, "r") as f:
content = f.read()
data_dict = content
# 如果缓存内容为空,直接重新获取token
if (content == ''):
print("token文件为空,重新获取并写入文件")
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过期,重新获取并写入文件")
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)
根据access token 获取模板列表
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'))
返回数据示例
{
"errcode": 0,
"errmsg": "ok",
"list": [
{
"template_id": "wDYzYZVxobJivW9oMpSCpuvACOfJXQIoKUm0PY397Tc",
"title": "购买成功通知",
"content": "购买地点{{keyword1.DATA}}\n购买时间{{keyword2.DATA}}\n物品名称{{keyword3.DATA}}\n",
"example": "购买地点:TIT造舰厂\n购买时间:2016年6月6日\n物品名称:咖啡\n"
}
]
}
