Therefore, we need to add two web references.
1. obtain your city from the IP address (if this is not available, and directly reference the webservice provided by the relevant website, your location may not be very accurate. If you use a vro ....)
2. Call the webservice to obtain weather data based on the City obtained in the previous step.
