我以与此处相同的方式实现了一个装饰器 如何在Flask中使用参数(用于授权)创建一个python装饰器函数 但问题仍未解决...
我有装饰器的这个功能
@blueprint.route('<var>')
@blueprint.my_decorator(var)
def function(var):
do stuff
我收到这个错误
NameError: global name 'var' is not defined
我该如何解决这个问题？
更新
蓝图是继承Blueprint类的类.所以我实现了这个方法
def my_decorator(self, fn):
@wraps(fn)
def decorator(*args, **kwargs):
value = kwargs['value']
# do stuff with value
return fn(*args, **kwargs)
return decorator
但仍然是一个未知的关键...
我开发了chrome扩展,我想在我的网站上进行内联安装.我有以下代码,但它似乎不起作用:
<head>
<link rel="chrome-webstore-item" href="https://chrome.google.com/webstore/detail/-extension_ID-">
<script>
function ExtInstall() {
if (chrome.app.isInstalled)
alert("already installed!");
else
chrome.webstore.install();
}
</script>
</head>
<body>
<button onclick="ExtInstall()" id="install-button">Add to Chrome</button>
</body>
我还将网站与扩展程序相关联,但它仍然无效.即使我安装了扩展名chrome.webstore.install(),chrome.app.isInstalled也会返回false.什么也没做.有任何想法吗？
