我正在使用HttpWebRequests联系API并需要添加标头,但编译器告诉我该方法不存在。 然而,当我检查MSDN时,它告诉我该方法已经存在。 设置我的UserAgent属性也会失败。
有人可以帮我吗?
try{
HttpWebRequest wr = (HttpWebRequest)HttpWebRequest.Create(url);
wr.Method = "GET";
wr.Headers.Add(System.Net.HttpRequestHeader.Authorization, string.Format("Bearer {0}", _accessToken));
wr.UserAgent = _appNameAndContact;
var resp = (System.Net.HttpWebResponse) await wr.BetterGetResponse();
if (resp.StatusCode == System.Net.HttpStatusCode.OK)
{
using (var sw = new System.IO.StreamReader(resp.GetResponseStream()))
{
var msg = sw.ReadToEnd();
User usr = JsonConvert.DeserializeObject<User>(msg);
//var results = JSONHelper.Deserialize<User>(msg);
return usr;
}
}
}

你必须使用这样的HttpRequestMessage:
using (var httpClient = new HttpClient())
{
var url = new Uri("http://bing.com");
var accessToken = "1234";
using (var httpRequestMessage = new HttpRequestMessage(HttpMethod.Get, url))
{
httpRequestMessage.Headers.Add(System.Net.HttpRequestHeader.Authorization.ToString(),
string.Format("Bearer {0}", accessToken));
httpRequestMessage.Headers.Add("User-Agent", "My user-Agent");
using (var httpResponseMessage = await httpClient.SendAsync(httpRequestMessage))
{
// do something with the response
var data = httpRequestMessage.Content;
}
}
}
