c# - 我可以使用 dotnet core 创建一个 uwp 应用程序吗？例如并使用仅在核心中可用的 httpclientfactory？

Question

我正在构建一个 uwp 应用程序，它将对服务进行休息调用以获取一些数据。我想使用 dotnet core 提供的 HttpClientFactory。是否可以在与 uwp 相同的项目中执行此操作？谢谢

我正在构建一个 uwp 应用程序，它将对服务进行休息调用以获取一些数据。

正如 MindSwipe 所说，目前我们无法HttpClientFactory在 UWP 中使用，如果您想使用 restful api 访问服务，请使用HttpClient.

例如：

Windows.Web.Http.HttpClient httpClient = new Windows.Web.Http.HttpClient();

//Add a user-agent header to the GET request. 
var headers = httpClient.DefaultRequestHeaders;

//The safe way to add a header value is to use the TryParseAdd method and verify the return value is true,
//especially if the header value is coming from user input.
string header = "ie";
if (!headers.UserAgent.TryParseAdd(header))
{
    throw new Exception("Invalid header value: " + header);
}

header = "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)";
if (!headers.UserAgent.TryParseAdd(header))
{
    throw new Exception("Invalid header value: " + header);
}

Uri requestUri = new Uri("http://www.contoso.com");

//Send the GET request asynchronously and retrieve the response as a string.
Windows.Web.Http.HttpResponseMessage httpResponse = new Windows.Web.Http.HttpResponseMessage();
string httpResponseBody = "";

try
{
    //Send the GET request
    httpResponse = await httpClient.GetAsync(requestUri);
    httpResponse.EnsureSuccessStatusCode();
    httpResponseBody = await httpResponse.Content.ReadAsStringAsync();
}
catch (Exception ex)
{
    httpResponseBody = "Error: " + ex.HResult.ToString("X") + " Message: " + ex.Message;
}
