如何访问flask中view函数以外的配置值

from flask import Flask

app = Flask(__name__)
app.config['SECRET_KEY'] = 'your_secret_key'

# 在视图函数中访问
@app.route('/')
def index():
    return f"Secret Key: {app.config['SECRET_KEY']}"

# 在其他地方访问
def some_function():
    with app.app_context():
        secret_key = app.config['SECRET_KEY']
        print(f"Secret Key from other function: {secret_key}")

from flask import Flask, current_app

app = Flask(__name__)
app.config['SECRET_KEY'] = 'your_secret_key'

# 在视图函数中访问
@app.route('/')
def index():
    return f"Secret Key: {current_app.config['SECRET_KEY']}"

# 在其他地方访问
def some_function():
    with app.app_context():
        secret_key = current_app.config['SECRET_KEY']
        print(f"Secret Key from other function: {secret_key}")

from flask import Flask, g

app = Flask(__name__)
app.config['SECRET_KEY'] = 'your_secret_key'

@app.before_request
def load_config():
    g.secret_key = app.config['SECRET_KEY']

# 在视图函数中访问
@app.route('/')
def index():
    return f"Secret Key: {g.secret_key}"

# 在其他地方访问
def some_function():
    with app.app_context():
        secret_key = g.secret_key
        print(f"Secret Key from other function: {secret_key}")

with app.app_context():
    secret_key = current_app.config['SECRET_KEY']

app.config.from_pyfile('config.py')
