Flask/Python - 我如何在 Flask 中運行這個 python 腳本並在 ZFC35FDC70D5FC69D256987A 頁面中渲染 output

Question

我編寫此代碼以獲取一些股票價格值，以及如何在 results.html 頁面中呈現 output 結果？ 我正在使用 Heroku 來制作這個應用程序。

請幫助我使用這個應用程序。 這是調用其他文件的主文件。

如果需要更多詳細信息來運行此應用程序，請告訴我。

這是我制作的代碼，用於在 view.html 頁面中顯示 output。 x.py

print('----EURO DO REMESSA ONLINE-----')
import melhor
print('-----COTAÇÃO DOLARHOJE.COM-----')
import cota
print('-----INDICADOR EURO COMERCIAL H1----')
import indicator
print('-----INVESTING VALOR EURO COM-----')
import invest
print( '-------------\n', 'Conhece a ti mesmo. (Tales de Mileto)', '\n-------------')

Answer 1

希望對大家有所幫助，對Python了解不多。 但聽起來如果您正在對 html 頁面進行服務器端渲染，您只需要一個模板引擎，例如 Jade、Pug 或類似的東西。

Answer 2

以下是一些示例供您參考：

https://www.grizzlypeaksoftware.com/articles?id=1m3W3llyJLy4YS5OpyyxBq

https://scotch.io/tutorials/getting-started-with-flask-a-python-microframework

https://scoutapm.com/blog/python-flask-tutorial-getting-started-with-flask

https://www.liquidweb.com/kb/getting-started-with-flask/

https://github.com/akibrhast/flask_base_template

基本上你需要了解的是如何創建一個后端服務器。 在這種情況下使用 flask。 通常與 flask 一起使用的模板引擎稱為 Jinja。 一旦您對您的數據發出請求調用，您就會希望通過 jinja 將其傳遞給您的路線。

這是一個基本示例：

from flask import Flask, flash, redirect, render_template, request, session, abort,url_for
import os

#from flask_login import login_user, current_user, logout_user, login_required #Optional login imports, need to 'pip install flask_login'

app = Flask(__name__)

@app.route('/')
def index():
  return render_template("base.html")

if __name__ == '__main__':
    app.secret_key = os.urandom(12)
    app.run(debug=True)
