这真的很奇怪,但我遇到了这个问题。一切都在工作,我几乎完成了应用程序,但突然间它停止了。我已经隔离了代码,我意识到当我注册蓝图并在路由上使用它时,它无法返回说没有找到URL。这是孤立的代码:
from flask import Flask, render_template, Blueprint
app = Flask(__name__)
home = Blueprint('home', __name__, static_folder='static', template_folder='template')
app.register_blueprint(home)
@home.route('/') #<---This one does not work
# @app.route('/') <--- This one works
def index():
return "This is the index route."
# return render_template('layer.html')
if __name__ == '__main__':
app.run()
答案 0 :(得分:4)
在定义路线后移动app.register_blueprint(home)
。
from flask import Flask, Blueprint
app = Flask(__name__)
home = Blueprint('home', __name__, static_folder='static', template_folder='template')
@home.route('/')
def index():
return "This is the index route."
app.register_blueprint(home)
if __name__ == '__main__':
app.run()
