错误：GetResultCore（布尔等待完成通知）

Question

我正在尝试调用 API url，但当我的代码运行此行时，我会遇到错误：

HttpResponseMessage response = client.GetAsync(new Uri(uri)).Result;

，

这是代码。

public static string SimpleGetAsync(string uri)
{
     string result = string.Empty;
     try
     {
          HttpClientHandler handler = new HttpClientHandler()
          {
              AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
          };

          HttpClient client = new HttpClient(handler);  
          HttpResponseMessage response = client.GetAsync(new Uri(uri)).Result;
                result = response.Content.ReadAsStringAsync().Result;
     }
     catch (Exception ex)
     {
                LogManager.WriteLogByDate(LogFile.Exception.ToString(), "Error HtmlHelper.SimpleGet (" + uri + ") :" + ex.Message + "\r\nWith stacktrace: " + ex.StackTrace + "\r\n\r\n");
     }
     return result;
}

这是错误信息

One or more errors occurred. at System.Threading.Tasks.Task`1.GetResultCore(Boolean waitCompletionNotification)

你尝试过制作方法吗

async

 public static async Task<string> SimpleGet(string uri)
    {
        string result = string.Empty;
        try
        {
            HttpClientHandler handler = new HttpClientHandler()
            {
                AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
            };

            HttpClient client = new HttpClient(handler);
            
            HttpResponseMessage response = await client.GetAsync(new Uri(uri)).ConfigureAwait(false);
            result = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
        }
        catch (Exception ex)
        {
            LogManager.WriteLogByDate(LogFile.Exception.ToString(), "Error HtmlHelper.SimpleGet (" + uri + ") :" + ex.Message + "\r\nWith stacktrace: " + ex.StackTrace + "\r\n\r\n");
        }
        return result;
    }
