Question

我是烧瓶新手。我有这个代码：你能告诉我一些我做错的事吗？感谢

from flask import Flask
from flask import request
from flask import render_template

app = Flask(__name__)

@app.route('/')
def my_form():
    return render_template('my-form.html')

@app.route('/', methods=['POST'])
def my_form_post():

    text = request.form['text']
    processed_text = text.upper()
    return processed_text
app.debug = True
print("asdsa")
if __name__ == '__main__':
    app.run()

我已将文件my-form.html放入此文件夹：C：\ Python33 \ Lib \ site-packages \ flask \ testsuite \ templates

但是当我刷新127.0.0.1:5000时，我得到了jinja2.exceptions.TemplateNotFound：

您将模板放在错误的位置。来自Flask文档：

Flask将在templates文件夹中查找模板。因此，如果您的应用程序是一个模块，那么该文件夹就在该模块的旁边，如果它是一个包，它实际上在您的包中：

有关详细信息，请参阅文档：http://flask.pocoo.org/docs/quickstart/#rendering-templates
