使用OpenWeatherMap API获取天气数据

OpenWeatherMap是一个提供全球天气数据的服务。以下是一个简单的示例，展示如何使用OpenWeatherMap API获取天气数据。

import Foundation

func fetchWeatherData(city: String) {
    let apiKey = "YOUR_API_KEY"
    let urlString = "http://api.openweathermap.org/data/2.5/weather?q=\(city)&appid=\(apiKey)"
    guard let url = URL(string: urlString) else { return }

    URLSession.shared.dataTask(with: url) { data, response, error in
        guard let data = data, error == nil else { return }

        let weatherData = try? JSONDecoder().decode(WeatherData.self, from: data)
        print(weatherData?.name ?? "No data")
    }.resume()
}

使用AccuWeather API获取详细天气信息

AccuWeather提供详细的天气信息，包括温度、湿度、风速等。

import Foundation

func fetchAccuWeatherData(city: String) {
    let apiKey = "YOUR_API_KEY"
    let urlString = "http://api.accuweather.com/locations/v1/cities/autocomplete?apikey=\(apiKey)&q=\(city)"
    guard let url = URL(string: urlString) else { return }

    URLSession.shared.dataTask(with: url) { data, response, error in
        guard let data = data, error == nil else { return }

        let cities = try? JSONDecoder().decode([City].self, from: data)
        print(cities?.first?.localizedName ?? "No data")
    }.resume()
}

使用Weatherstack API获取天气预报

Weatherstack提供全球天气预报，包括当前天气、小时天气、三天天气预报等。

import Foundation

func fetchWeatherstackData(city: String) {
    let apiKey = "YOUR_API_KEY"
    let urlString = "http://api.weatherstack.com/current?access_key=\(apiKey)&query=\(city)"
    guard let url = URL(string: urlString) else { return }

    URLSession.shared.dataTask(with: url) { data, response, error in
        guard let data = data, error == nil else { return }

        let weatherData = try? JSONDecoder().decode(WeatherData.self, from: data)
        print(weatherData?.name ?? "No data")
    }.resume()
}
