Question

我正在尝试按照此处给出的说明进行操作：Adding a favicon to a Flask server without HTML 关于如何将网站图标添加到 Flask 应用程序，但它对我不起作用。这是我的申请文件：

def first_call(*args, **kwargs) -> int:
    """Call this first."""
    # you can also access to the params with args array such as args[0]
    return args[0]


def second_call(*args, **kwargs) -> int:
    """Call this second."""
    return 2


def router_function(*args, **kwargs) -> int:
    """Call the first function, then with this same function object, call the second."""
    call = kwargs.get("call")

    if call == 1:
        return first_call(*args, **kwargs)
    elif call == 2:
        return second_call(*args, **kwargs)

    return 0


# Desired behavior
first_call_ret = router_function(100, call=1)  # Calls first_call
second_call_ret = router_function(200, call=2)  # Calls second_call

print(first_call_ret)  # OUTPUT: 100 because we returned the first argument at first_call
print(second_call_ret)  # OUTPUT: 2 since we returned 2 from second_call (hardcoded)

这是我的目录结构：

from flask import Flask,send_from_directory
application=Flask(__name__)

@application.route('/')
def main():
    return '<html><p>hello world</p></html>'

@application.route('/favicon.ico')
def favicon():
    return send_from_directory(os.path.join(application.root_path, 'static'),
        'favicon.ico',mimetype='image/vnd.microsoft.icon')

if __name__=='__main__': application.run(debug = True)

当我在 Firefox 中运行该应用程序时，没有显示网站图标，而当我在 Chrome 中运行它时，会显示默认的网站图标。我使用此网站将 png 转换为 ico 文件： https://www.freeconvert.com/png-to-ico

请告诉我哪里出错了。

当我在 chrome 中运行应用程序时，我在控制台中收到此错误：

➜  demo ls -R
application.py static

./static:
favicon.ico

我需要导入 os，这是工作应用程序：

from flask import Flask,send_from_directory
import os
application=Flask(__name__)

@application.route('/')
def main():
    return '<html><p>hello world</p></html>'

@application.route('/favicon.ico')
def favicon():
    return send_from_directory(os.path.join(application.root_path, 'static'),
        'favicon.ico',mimetype='image/vnd.microsoft.icon')

if __name__=='__main__': application.run(debug = True)
