无法从 openweathermap 获取天气图标 [英] Can't fetch weather icons from openweathermap

问题描述

我一直在尝试从 openweathermap api 为 python 应用程序获取天气图标，但由于某种原因我无法这样做.

但是，我可以将图标打印为文本，例如它的代码像 "3d" 或 "3n" 但不是图像.

当我尝试打印图像时，会弹出错误_tkinter.TclError: image "03n" does not exist.

我的代码如下.

导入请求从 tkinter 导入 *根 = Tk()root.geometry("250x250+0+0")root.configure(bg='black')url = 'http://api.openweathermap.org/data/2.5/weather?appid=c73d9cdb31fd6a386bee66158b116cd0&q=karachi&units=metric'json = requests.get(url).json()温度 = json['main']['temp']icon = json['天气'][0]['icon']#icon1 = 'http://openweathermap.org/img/wn/[e-mail]'#打印(图标)root.lab1 = 标签(根，图像=图标)root.lab1.pack(side=TOP)root.lab= Label(text=(root,'{} deg celcius'.format(temperature)),font=("Helvetica 15"), bg='black', fg='white')root.lab.pack(side=LEFT)

问题:从 openweathermap 获取天气图标

根据评论:

• 图标的值为03n".当然，tkinter 不知道如何证明这一点.您必须在 openweathermap 的 API 文档中查看如何获取该图标.– @zvone

• 请参阅 SO:答案

  导入 tkinter 作为 tk导入请求，base64类 OpenWeatherMap:APPID = 'c73d9cdb31fd6a386bee66158b116cd0'def __init__(self):self.url = "http://api.openweathermap.org/data/2.5/weather?appid={appid}&q={city}&units=metric"self.json = {}def get_city(self, city):url = self.url.format(appid=OpenWeatherMap.APPID, city=city)self.json = requests.get(url).json()返回 self.jsondef get(self, key):返回 self.json['main'][key]def get_icon_data(self):icon_id = self.json['天气'][0]['icon']url = 'http://openweathermap.org/img/wn/{icon}.png'.format(icon=icon_id)响应 = requests.get(url, stream=True)返回 base64.encodebytes(response.raw.read())类OWIconLabel(tk.Label):def __init__(self, parent, **kwargs):Weather_icon = kwargs.pop('weather_icon', None)如果weather_icon 不是None:self.photo = tk.PhotoImage(data=weather_icon)kwargs['image'] = self.photosuper().__init__(parent, **kwargs)

  用法:

  类应用程序(tk.Tk):def __init__(self):super().__init__()self.geometry("220x120+0+0")self.configure(bg='black')owm = OpenWeatherMap()owm.get_city('卡拉奇')温度 = owm.get('temp')temp_icon = OWIconLabel(self,weather_icon=owm.get_icon_data())temp_icon.grid(row=0, column=0)self.temp = tk.Label(self,text='{} deg celcius'.format(温度),font=("Helvetica", 15), bg='black', fg='white')self.temp.grid(row=1, column=0)如果 __name__ == '__main__':应用程序().主循环()

  使用 Python 测试:3.5

  I have been trying to fetch weather icons from openweathermap api for a python application, but for some reason I am not able to do so.

  I am however, able to print the icon as text for e.g. its code like "3d" or "3n" but not the image.

  When I try to print the image, the error _tkinter.TclError: image "03n" doesn't exist pops up.

  My code is below.

  import requests
  from tkinter import *
  
  root = Tk()
  root.geometry("250x250+0+0")
  root.configure(bg='black')
  url = 'http://api.openweathermap.org/data/2.5/weather?appid=c73d9cdb31fd6a386bee66158b116cd0&q=karachi&units=metric'
  
  json = requests.get(url).json()
  temperature = json['main']['temp']
  icon = json['weather'][0]['icon']
  #icon1 = 'http://openweathermap.org/img/wn/[e-mail]'
  #print(icon)
  root.lab1 = Label(root,image=icon)
  root.lab1.pack(side=TOP)
  root.lab= Label(text=(root,'{} deg celcius'.format(temperature)),font=("Helvetica 15"), bg='black', fg='white')
  root.lab.pack(side=LEFT)

  Question: fetch weather icons from openweathermap

  According to the comments:

  • The value of icon is "03n". Of course tkinter does not know how to show that. You have to see in openweathermap's API docs how to fetch that icon. – @zvone

  • see SO:Answer set a tkinter app icon with a URL? to get the icon.
    use f'http://openweathermap.org/img/wn/{icon}.png' as url. – @Stef

  import tkinter as tk
  import requests, base64
  
  class OpenWeatherMap:
      APPID = 'c73d9cdb31fd6a386bee66158b116cd0'
  
      def __init__(self):
          self.url = "http://api.openweathermap.org/data/2.5/weather?appid={appid}&q={city}&units=metric"
          self.json = {}
  
      def get_city(self, city):
          url = self.url.format(appid=OpenWeatherMap.APPID, city=city)
          self.json = requests.get(url).json()
          return self.json
  
      def get(self, key):
          return self.json['main'][key]
  
      def get_icon_data(self):
          icon_id = self.json['weather'][0]['icon']
          url = 'http://openweathermap.org/img/wn/{icon}.png'.format(icon=icon_id)
          response = requests.get(url, stream=True)
          return base64.encodebytes(response.raw.read())
  
  
  class OWIconLabel(tk.Label):
      def __init__(self, parent, **kwargs):
          weather_icon = kwargs.pop('weather_icon', None)
          if weather_icon is not None:
              self.photo = tk.PhotoImage(data=weather_icon)
              kwargs['image'] = self.photo
  
          super().__init__(parent, **kwargs)
  

  Usage:

  class App(tk.Tk):
      def __init__(self):
          super().__init__()
          self.geometry("220x120+0+0")
          self.configure(bg='black')
  
          owm = OpenWeatherMap()
          owm.get_city('karachi')
  
          temperature = owm.get('temp')
  
          temp_icon = OWIconLabel(self, weather_icon=owm.get_icon_data())
          temp_icon.grid(row=0, column=0)
  
          self.temp = tk.Label(self,
                               text='{} deg celcius'.format(temperature),
                               font=("Helvetica", 15), bg='black', fg='white')
          self.temp.grid(row=1, column=0)
  
  
  if __name__ == '__main__':
      App().mainloop()
