如何在屏幕上显示当前类型的鼠标光标?(不仅在我的应用程序窗口,全局.)或者至少可以检测当前是否显示默认光标?无论是Carbon还是Cocoa都可以 - 甚至是其他工作API,最好是官方API.
这是我尝试过的:
NSCursor *sysCursor = [NSCursor currentSystemCursor];
if (sysCursor == nil) {
NSLog(@"nil");
}
if ([sysCursor isEqual: [NSCursor arrowCursor]] ||
[sysCursor isEqual: [NSCursor contextualMenuCursor]] ||
[sysCursor isEqual: [NSCursor closedHandCursor]] ||
[sysCursor isEqual: [NSCursor crosshairCursor]] ||
[sysCursor isEqual: [NSCursor disappearingItemCursor]] ||
[sysCursor isEqual: [NSCursor dragCopyCursor]] ||
[sysCursor isEqual: [NSCursor dragLinkCursor]] ||
[sysCursor isEqual: [NSCursor IBeamCursor]] ||
[sysCursor isEqual: [NSCursor openHandCursor]] ||
[sysCursor isEqual: [NSCursor operationNotAllowedCursor]] ||
[sysCursor isEqual: [NSCursor pointingHandCursor]] ||
[sysCursor isEqual: [NSCursor resizeDownCursor]] ||
[sysCursor isEqual: [NSCursor …

在弹性beanstalk实例上设置django 以允许Elastic Load Balancer IP?
背景
我在弹性beanstalk上部署了django网站.网站域名被添加到ALLOW_HOSTS
正常请求被django正确接受.
ALLOWED_HOSTS = ['.mydomain.com']

Elastic Load balancer直接使用IP地址访问Elastic beanstalk实例以进行运行状况检查,因此下一行允许运行状况检查:
# add elastic beanstalk instance local ip
aws_ip = requests.get('http://169.254.169.254/latest/meta-data/local-ipv4', timeout=0.1).text
ALLOWED_HOSTS.append(aws_ip)

但我仍然得到无效的HOST IP错误,似乎弹性负载均衡器公共IP访问了弹性beanstalk实例.有针对EC2部署的在线解决方案,因为您可以将HTTPD软件设置为在IP直接访问时设置http HOST标头.但我们无法在弹性beanstalk上配置apache.那么如何将弹性负载均衡器IP添加到ALLOW_HOSTS
?
