如何在不使用请求的情况下直接从代码调用flask端点

from flask import Flask, request
from flask.testing import FlaskClient

app = Flask(__name__)

@app.route('/endpoint', methods=['GET'])
def endpoint():
    return 'Hello, World!'

client = app.test_client()

response = client.get('/endpoint')

data = response.get_data(as_text=True)

from flask import Flask, request
from flask.testing import FlaskClient

app = Flask(__name__)

@app.route('/endpoint', methods=['GET'])
def endpoint():
    return 'Hello, World!'

client = app.test_client()
response = client.get('/endpoint')
data = response.get_data(as_text=True)

print(data)  # 输出：Hello, World!
