服务发现(Win Server,Android客户端)(Service Discovery (Win Server, Android Clients))

我有一对基本上可以工作的服务器(Windows)和客户端(Android)应用程序,需要在局域网上运行,他们几乎一无所知,直到启动。 关于我能做的唯一假设是WIFI和DHCP分配的IP地址。

我将需要一个客户端找到服务器的机制。 我有一个完整的字母汤的选择,但我以前不必这样做,所以我问你,StackOverflow的优秀人士,寻求建议。

NSD(网络服务发现)似乎是Android上的首选方法,但在Windows上似乎不存在。 是否有可互操作的Windows协议?

我得到的印象是,DNS-SD无法在我的服务器出现之前配置DNS而无法正常工作。

由于我需要知道的只是服务器的IP,所以创建自己的多播组并让服务器宣布自己的方式是非常诱人的。 有没有理由不采用这种方法?


I've got a largely working pair of server (Windows) and client (Android) applications that will need to run on a LAN they will pretty much know nothing about until fired up. About the only assumptions I can make are WIFI and DHCP allocated IP addresses.

I will need a mechanism for the clients to find the server. I've got an entire-alphabet-soup of choices but I've not had to do this before, so I'm asking you, the fine people of StackOverflow, for advice.

NSD (Network Service Discovery) seems to be the preferred method on Android but seems non-existent on Windows. Is there an inter-operable Windows protocol?

I get the impression that DNS-SD wouldn't work for this without configuring the DNS before my server showed up on it.

As all I need to know is the IP of the server, it's very tempting to just make my own multicast group and have the server announce itself way. Is there a reason not to go with this approach?

最满意答案

您可以遍历现有用户,并调用get_or_create()

for user in User.objects.all():
    UserProfile.objects.get_or_create(user=user)

如果您愿意,可以将其放入数据迁移中 ,或者在shell中运行代码。


You can loop through the existing users, and call get_or_create():

for user in User.objects.all():
    UserProfile.objects.get_or_create(user=user)

You could put this in a data migration if you wish, or run the code in the shell.
