Add any allowed methods to a route in the decorator, eg将任何允许的方法添加到装饰器中的路由，例如
@app.route('/index', methods=['POST', ...])
EDIT: You should probably also check on the method field of request instead of just method .编辑：您可能还应该检查request的method字段，而不仅仅是method 。
if request.method == 'POST':

By default routes only accept the GET method.默认情况下，路由只接受GET方法。 If you want your route to answer to other methods, pass a custom methods parameter to @app.route as follows如果您希望您的路由响应其他方法，请将自定义methods参数传递给@app.route ，如下所示
@app.route('/', methods=['GET', 'POST',])
...
@app.route('/index', methods=['GET', 'POST',])
...
