如何让我的文本根据httprequest的结果不断更改，直到满足结束条件？

from flask import Flask, render_template
import requests

app = Flask(__name__)

@app.route('/')
def update_text():
    url = 'http://example.com/api'  # 替换为实际的API地址
    end_condition = False  # 结束条件
    text = ''  # 初始化文本内容

    while not end_condition:
        response = requests.get(url)
        data = response.json()  # 假设API返回JSON格式数据

        # 判断结束条件
        if data['status'] == 'finished':
            end_condition = True

        # 更新文本内容
        text = data['text']

    return render_template('index.html', text=text)  # 渲染模板并返回

if __name__ == '__main__':
    app.run()
