Ask the bot to tell you the weather (precipitation information) using the weather information API (YOLP) provided by Yahoo ~ slack bot development with python ④ ~
What to do in this article
If you mutter to the bot, "Tell me if it's raining," I'll let you know the precipitation information as follows.
By the way, the articles so far are as follows Automatically create JIRA tickets with slack bot ~ slack bot development with python ① ~ JIRA ticket with slack bot → Automation of Slack notification ~ slack bot development with python② ~ Notify slack when the switch sales page is updated ~ slack bot development with python ③ ~
Mounting method
・ Hit the following API to get the precipitation intensity and use that information to notify slack. Weather Information API With this
- You can get the rain intensity of the specified latitude and longitude.
- You can get the predicted precipitation intensity up to 60 minutes later from the measured precipitation intensity at the current time.
Pre-registration (free) is required to hit the API provided by yahoo For details on how to register, please refer to the following people who have summarized it wonderfully. Get weather information using Yahoo! Open Local Platform (YOLP) and let Raspberry Pi talk with AquesTalkPi
Directories and files
I will add it to my_mention.py this time as well. However, as the amount of code has increased, I will change to the method of calling the code in the scripts directory from mymention.py.
slackbot #A directory that organizes programs. Any name is fine
├─ run.py #Start the bot by running this program
├─ slackbot_settings.py #File to write settings related to bot
└─ plugins #Add bot functionality to this directory
├─ __init__.py #A file to indicate the module. Sky is fine
└─ my_mention.py #Features each file. Any name is fine
└─ files_dir #Store the contents acquired by curl in this directory
├─ switch.html_1 #Content acquired with curl
└─ switch.html_2 #Content acquired with curl
└─ switch.html_3..4..5..6..

Program (my_mention.py)
The contents to be added to my_mention.py are as follows
# coding: utf-8

@respond_to('(.rain*)')
def confirm_weather(message, something):
weather_class = ConfirmWeather()
weather_class.return_rainfall(message)
Program (confirm_weather.py)
The contents of confirm_weather.py to be placed in the actual script directory are as follows

point
11 # Latitude and longitude of Ginza Can be obtained from here http://www.geocoding.jp/
22 data_json = json.loads(response.decode('utf-8'))
You can get json in the following format by hitting api
{'ResultInfo': {'Start': 1, 'Count': 1, 'Description': '', 'Status': 200, 'Latency': 0.003202, 'Copyright': '(C) Yahoo Japan Corporation.', 'Total': 1},
'Feature': [{'Name': 'point(Actually, the latitude and longitude are here.)July 30, 2017 Weather information for 60 minutes from 00:15',
'Property': {'WeatherList': {'Weather': [{'Rainfall': 0.0, 'Type': 'observation', 'Date': '201707300015'}, {'Rainfall': 1.55, 'Type': 'forecast', 'Date': '201707300025'}, {'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707300035'}, {'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707300045'}, {'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707300055'}, {'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707300105'}, {'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707300115'}]}, 'WeatherAreaCode': 4410}, 'Id': '201707300015_139.76898_35.672859', 'Geometry': {'Type': 'point', 'Coordinates': 'Actually, the latitude and longitude are here.'}}]}
All you need is Rainfall This API will tell you from the current observed value to the predicted value one hour later.
25 weather_info = data_json['Feature'][0]['Property']['WeatherList']
If only the above information can be obtained, it is ok, so specify the key and retrieve it. If you print this, you can get only the information you want as follows
[{'Rainfall': 0.0, 'Type': 'observation', 'Date': '201707291350'},
{'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707291400'},
{'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707291410'},
{'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707291420'},
{'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707291430'},
{'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707291440'},
{'Rainfall': 0.0, 'Type': 'forecast', 'Date': '201707291450'}]
Based on this information, we will turn the for statement
28 Turn the loop while getting the index with the # enumerate method 29 for index, var in enumerate(weather_info): Turn the for statement while getting the index. This is because the first item is the current measured value, so it is necessary to make the word at the end of the word the present progressive tense.
50 def retrun_rain_level(self, rainfall):
Take the value of Rainfall as an argument and define the message based on the measured value The intensity of rain and how it rains are taken from the following website of the Japan Meteorological Agency. http://www.jma.go.jp/jma/kishou/know/yougo_hp/amehyo.html
If you do this, you will get a result like the beginning
that's all
