使用render_template和Flask获取500内部服务器错误

问题描述：

我正在尝试使用Flask呈现HTML模板.我的软件运行良好，现在每次出现 500 Internal Server Error .如果我只用一个字符串替换 render_template 函数，一切就可以正常进行.我在做什么错了?

I am trying to use Flask to render an HTML template. I had it working great and now each time I get a 500 Internal Server Error. If I replace the render_template function just a string, things work fine. What am I doing wrong?

初始化 .py:

from flask import Flask, render_template

app = Flask(__name__)


@app.route('/')
def homepage():
    return render_template("main.html")

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

/templates/

main.html in /templates/

<!DOCTYPE html>
<html lang="en">
<p>test</p>
</html>

答

必须定义template_folder静态文件所在的位置.

The template_folder has to be defined where the static files are located.

如果main.html文件与init.py位于同一文件夹中，则请包含以下代码:

If the main.html file is in the same folder as the init.py, then include the following code:

import os

project_root = os.path.dirname(__file__)
template_path = os.path.join(project_root, './')

app = Flask(__name__, template_folder=template_path)

希望它现在可以正常工作.

Hopefully it works now.
