func TestHttp3(t *testing.T){
    queryWeatherURL := "http://wthrcdn.etouch.cn/weather_mini?city=杭州"

    httpclient := &http.Client{}
    resp, err := httpclient.Get(queryWeatherURL)
    if err!=nil {
        fmt.Println(err)
        return
    }
    defer resp.Body.Close()
    cityWeather :=  new(CityWeather)
    _ = json.NewDecoder(resp.Body).Decode(cityWeather)

    fmt.Println(cityWeather.Data.City)

}
