Angular Yahoo天气API

Question

我对Yahoo Weather API有一个问题。我应该如何请求从Yahoo Weather API获取数据？

import { Injectable } from '@angular/core';
import {Observable} from 'rxjs';
import {HttpClient} from '@angular/common/http';

@Injectable()
export class WeatherService {
  constructor(private http: HttpClient) { }

  getWeatherForecast(city: string): Observable<any> {
   const url = 'https://query.yahooapis.com/v1/public/yql?q=select wind from 
   weather.forecast where woeid=2460286';
   return this.http.get(url);
  }
}

​

Answer 1

工作示例：stackblitz

您唯一的问题是您忘记在url字符串中添加：&format=json。

默认情况下，返回的数据为XML格式。

Answer 2

这是一个简单的例子，但我希望它能对你有所帮助。我将在这里使用一个名为axios的库：

​

const url = "https://query.yahooapis.com/v1/public/yql?q=select item.condition from weather.forecast where woeid in (select woeid from geo.places(1) where text='Sunderland') and u='c'&format=json";
  
    const getWeatherData = () => {
         axios.get(url)
        .then(res => console.log(res.data.query.results.channel.item.condition))
        .catch(err => console.log(err.data))
    }
    
    getWeatherData();
