universal windows app ,制作 WebRequest Method = GET
universal windows app , making a WebRequest Method = GET
有谁知道如何获取 WebResponse 吗?? GetResponse() 方法已过时,顺便说一句,它是 windows 通用应用程序。
Uri uri = new Uri("myuri");
HttpClient httpclient = new HttpClient();
HttpWebRequest webrequest = (HttpWebRequest)HttpWebRequest.Create(uri);
httpclient.DefaultRequestHeaders.Add("name", "value");
httpclient.DefaultRequestHeaders.Accept.TryParseAdd("application/json");
webrequest.Method = "GET";
HttpWebResponse response = webrequest.GetResponseAsync();
StreamReader streamReader1 = new StreamReader(response.GetResponseStream());
已解决:
这样解决了:private async void Start_Click(object sender, RoutedEventArgs e)
{
response = new HttpResponseMessage();
outputView.Text = "";
httpClient.DefaultRequestHeaders.Add("name", "value");
// The value of 'InputAddress' is set by the user and is therefore untrusted input.
// If we can't create a valid URI,
// We notify the user about the incorrect input.
Uri resourceUri = new Uri("myuri")
string responseBodyAsText;
try
{
response = await httpClient.GetAsync(resourceUri);
response.EnsureSuccessStatusCode();
responseBodyAsText = await response.Content.ReadAsStringAsync();
}
catch (Exception ex)
{
// Need to convert int HResult to hex string
statusText.Text = "Error = " + ex.HResult.ToString("X") +
" Message: " + ex.Message;
responseBodyAsText = "";
}
// Format the HTTP response to display better
responseBodyAsText = responseBodyAsText.Replace("<br>", Environment.NewLine);
outputView.Text = responseBodyAsText;
您需要包含 await
关键字。
HttpWebResponse response = await webrequest.GetResponseAsync();
