so we're going to add a Web reference for a total of two
1. According to the IP address to get your city (if there is no this, and directly refer to the relevant site to provide webservice, your location may not be very accurate, if you use the router .... And so on, I do not know that everyone is feeling the same)
2. According to the last acquired city, call the webservice to get the weather data.
