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"
}
]
