asp.net MVC项目 - 如何在控制器中使用API​​网址

Question

我需要在控制器中调用此API freegeoip.net/xml/userIpAddress来获取其数据。像这样freegeoip.net/xml/4.2.2.2

这是我的控制器

public ActionResult Index(string language)
{
    if (String.IsNullOrWhiteSpace(language) == false)
    {
        Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(language);
        Thread.CurrentThread.CurrentUICulture = new CultureInfo(language);
    }

     else if (String.IsNullOrWhiteSpace(language))
    {
        string userIpAddress = this.Request.UserHostAddress;

       //here how I can call freegeoip.net/xml/userIpAddress

    }

}

这是XML响应的内容：

<Response>
 <IP>4.2.2.2</IP>
 <CountryCode>US</CountryCode>
 <CountryName>United States</CountryName>
 <RegionCode/>
 <RegionName/>
 <City/>
 <ZipCode/>
 <TimeZone/>
 <Latitude>37.751</Latitude>
 <Longitude>-97.822</Longitude>
 <MetroCode>0</MetroCode>
 </Response>

使用func numberOfSections(in collectionView: UICollectionView) -> Int { return items.count / 3 + 1 } func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return min(3, items.count - 3 * section) } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let item = items[indexPath.section * 3 + item] // do something with item } ：
