如何从Windows Phone 8中的HTTPS网站下载字符串

Question

我是Windows手机开发者，我想从HTTPS网站下载字符串，我使用

WebClient most_down_download = new WebClient();
most_down_download.DownloadStringCompleted += Most_down_download_DownloadStringCompleted;
most_down_download.DownloadStringAsync(new Uri(https_url));

但它不起作用。你能救我吗？

Answer 1

也许是这样的？使用HTTP客户端代替Web客户端（8.1）

HttpClient http = new System.Net.Http.HttpClient();
HttpResponseMessage response = await http.GetAsync(https_url);
webresponse = await response.Content.ReadAsStringAsync();

您需要生成Most_down_download_DownloadStringCompleted事件处理程序，如下所示

void Most_down_download_DownloadStringCompleted(object sender, 
                              System.Net.DownloadStringCompletedEventArgs e)
{
    try
    {
        if (e.Error == null)
        {
            string response = e.Result.ToString();
        }
    }
    catch (Exception ex)
    { }
}

在e.Result.ToString()中你从网站上获取字符串
