preface

I have obtained weather data before, displayed it in the front end, checked some third-party support, and then used OpenWeather. In this record to share, for your reference.

(I am Java after midnight, in nuggets this share experience, those who rely on copy of the handling of the author, without permission, do not copy the article)

Benefits: free enough to use, simple mailbox registration can, not enough to register ten key, logic cycle in the code to use. Disadvantages: entry is the name of the city, some will not query, query can only go some of the bottom strategy.

Interface Support Description

Here’s a screenshot of the translation:

Let’s take a look at the current weather

The current weather

By geographic coordinates

Api.openweathermap.org/data/2.5/weather?lat= {lat} & lon = {lon} & appid = [{API key}] (https://home.openweathermap.org/api_keys)

According to the city ID

Api.openweathermap.org/data/2.5/weather?id=} {city id appid = [{API key}] (https://home.openweathermap.org/api_keys) The city ID can be downloaded directly from his place

Of course you can support batch.

Returns the object

Focus on the returned data structure:

{" coord ": {" lon" : 122.08, "lat" : 37.39}, "weather" : [{" id ": 800," main ":" Clear ", "description" : "The clear sky", "icon" : "01 d"}], "the base", "crisis", "main" : {" temp ": 282.55," feels_like ": 281.86," temp_min ": "Limit ": {" limit ": {" limit ": {" limit ": {" limit ": {" limit ": {" limit ": {" limit ": {" limit ": { 350}, "clouds" : {" all ": 1}," dt ": 1560350645," sys ": {" type" : 1, "id" : 5122, the "message" : 0.0139, "country" : "US", "sunrise": 1560343627, "sunset": 1560396563 }, "timezone": -25200, "id": 420006353, "name": "Mountain View", "cod": 200 }Copy the code

Focus on the description, the intuition to see if it works for you

The code logic called:Copy the code
HttpResponse<String> stringHttpResponse = Unirest.get(weatherUrl + "/weather").queryString("lang", lang).queryString("units", units).queryString("q", city).queryString("appid", weatherKey).asString();
String body = stringHttpResponse.getBody();
Copy the code

conclusion

This third party weather can still meet daily needs, especially if it is global.
