Question

我设置了一个天气应用程序，但是当我单击按钮获取天气时出现此错误？在此应用程序中，我创建了thread来进行后台处理。在这里，我试图获取self.text的值并在另一个函数中进行访问。

错误：

thread_weather_icon =线程（target = self.weather_icon， args = {self.text，））文件 “ C：\ Users \ ABC \ AppData \ Local \ Programs \ Python \ Python37-32 \ lib \ tkinter__init __。py”，第2101行，位于 getattr 返回getattr（self.tk，attr）AttributeError：'_tkinter.tkapp'对象没有属性'text'

我不知道为什么会收到此错误？

我尝试更改此设置，但仍然遇到错误：

class App(tk.Tk):
    def __init__(self, *args, **kwargs):
        tk.Tk().__init__(self, *args, **kwargs)

        super().__init__()

        self.title('AccWeather')
        self.geometry('600x500')

我的代码：

from tkinter import *
from bs4 import BeautifulSoup
from threading import  Thread
from io import BytesIO
from PIL import ImageTk, Image

class gui(Tk):
    def __init__(self):
        Tk.__init__(self)

        get_text = '+'.join(split)
        print(get_text)
        url = 'https://www.iconfinder.com/search/?q='+get_text
        req = requests.get(url).content
        soup = BeautifulSoup(req, 'html.parser')
        img_url = soup.find('img', {'class': 'd-block'})['src']
        image_content = requests.get(img_url).content

        self.icon['image'] = self.photo



if __name__ == '__main__':
    start = gui()
    start.mainloop()

请，我能理解吗。

Answer 1

self.weather_icon需要在self.text中创建的self.get_weather，因此self.get_weather必须在self.weather_icon之前运行，而self.weather_icon必须等到{{ 1}}结束其工作-确保self.get_weather已经存在。

最好将两个函数的代码放到一个函数中，然后在一个线程中运行。

self.text

AttributeError：'_tkinter.tkapp'对象在tkinter中没有属性'text'
