【Day 12】Rich Menu 主选单

我们拿 YouBike 微笑单车 官方帐号为例。
红色框框我们都会称作为「主选单」，很多官方帐号都有（基本上应该是标配了吧～）

所以我们也不例外，来试试看自己写一个主选单吧～！

主选单 Rich Menu

也是废话不多说，先送上官网传送门。

官网部分对 Rich Menu 主选单的解释：

客制一个表单（或主选单）显示在您的 Line 官方帐後聊天室版面。更多讯息请看Using rich menus

rich_menu.py

主选单建议在另一个 python 档去撰写执行，因为他并不是一个需要一直 call request 的东西。

步骤一

只要 import 两个东西

import requests
import json

接着我们要使用好几天以前的东西 token，我们需要 Channel access token (long-lived)。

import requests
import json

LINE_CHANNEL_ACCESS_TOKEN = 'UmN0XsFJwcHP8lL7cPrvu30LXwqhMfni5+cTHdjrHKfOGW3DdgNh04ZmflN74CzwyhcRqiDCSzbnGDXhKxRwzXeYmO/1ELsnZFZnKJneME5cWq+hmbUjCongPvcsaSVOI1Ml6KfKoHybjIGM67pFXQdB04t89/1O/w1cDnyilFU='

token = LINE_CHANNEL_ACCESS_TOKEN

Authorization_token = "Bearer " + LINE_CHANNEL_ACCESS_TOKEN

headers = {"Authorization":Authorization_token, "Content-Type":"application/json"}

body = {
    "size": {"width": 2500, "height": 1686},
    "selected": "false",
    "name": "Menu",
    "chatBarText": "更多资讯",
    "areas":[
        {
          "bounds": {"x": 113, "y": 45, "width": 1036, "height": 762},
          "action": {"type": "message", "text": "身体资讯"}
        },
        {
          "bounds": {"x": 1321, "y": 45, "width": 1036, "height": 762},
          "action": {"type": "message", "text": "营养素"}
        },
        {
          "bounds": {"x": 113, "y": 910, "width": 1036, "height": 762},
          "action": {"type": "message", "text": "吃"}
        },
        {
          "bounds": {"x": 1321, "y": 910, "width": 1036, "height": 762},
          "action": {"type": "message", "text": "运动gogo"}
        }
    ]
  }

req = requests.request('POST', 'https://api.line.me/v2/bot/richmenu',
                       headers=headers,data=json.dumps(body).encode('utf-8'))

print(req.text)

我们此时 print 出来的值为：

D:\anaconda3\python.exe F:/AI/Line_Chatbot/django_chatbot/django_chatbot/rich_menu.py
{"richMenuId":"richmenu-一串数字"}

richmenu-一串数字
这是我们的 rich menu 的 ID，要记住！！

得到我们要的 ID 以後，上面 body 部分就不是重点，也只需要执行这一次。（注解掉注解掉）

步骤二

from linebot import (
    LineBotApi, WebhookHandler
)

line_bot_api = LineBotApi(token)
rich_menu_id = "Rich Menu ID" # 设定成我们的 Rich Menu ID

path = "path of your image" # 主选单的照片路径

with open(path, 'rb') as f:
    line_bot_api.set_rich_menu_image(rich_menu_id, "image/png", f)

要注意，图片也只要设定一次就好，要不然会出现 error

步骤三

req = requests.request('POST', 'https://api.line.me/v2/bot/user/all/richmenu/'+rich_menu_id,
                       headers=headers)
print(req.text)

rich_menu_list = line_bot_api.get_rich_menu_list()

把他家进我们的 chatbot 里
print()出来的结果会是空的～是正常的。

跑完这一区以後，就可以执行了专案了！

可以看到主选单跑出来罗～～（洒花

小结

我们重新看一下程序码

import requests
import json
