从 Task<HttpResponseMessage> 获取 HttpResponseMessage

Question

在 HttpClient using 语句中，我需要从某处 HttpResponseMessage 解包。

using (HttpClient client = new HttpClient())
{
     client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", authUser);
     Task<HttpResponseMessage> m = client.GetAsync(url);   
     // HttpResponseMessage msg = ???              
     task.Wait();
     return task.Result;
}

我的问题是：如何从这一行获取 HttpResponseMessage

Task<HttpResponseMessage> m = client.GetAsync(url);   

Answer 1

你应该await这个任务：

HttpResponseMessage m = await client.GetAsync(url);   

为此，需要将调用方法标记为async。

Answer 2

要获取 HttpResponseMessasge，您应该使用 Task.Result 属性。 这是从 Task 获得的带有 HttpResponseMessage 的代码（稍作修改）：

using (HttpClient client = new HttpClient())
{
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", authUser);
    Task<HttpResponseMessage> task = client.GetAsync(uri);
    **HttpResponseMessage msg = task.Result;**
    task.Wait();
    return task.Result;
}
