OAuth 2.0注意事项:
1、 获取access_token时,请使用POST
1 private static string GetAuthorization(string username, string password) 2 { 3 string authorization = string.Format("{0}:{1}", username, password); 4 5 return "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(authorization)); 6 }View Code

JObject.Parse(result)["access_token"].Value<string>() : result; 62 }View Code
2、 访问需要授权的Api,请使用http/https协议,并且加上access token的Header
3 、Header格式为"Authorization: Bearer access_token",其中Bearer后面有一个空格
1 /// <summary> 2 /// HttpGet 3 /// </summary> 4 /// <param name="url"></param> 5 /// <param name="token"></param> 6 /// <param name="contentType"></param> 7 /// <returns></returns> 8 private static string HttpGet(string url, string token, string contentType = "application/x-www-form-urlencoded") 9 { 10 HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url); 11 httpWebRequest.Method = "GET"; 12 httpWebRequest.ContentType = contentType; 13 httpWebRequest.Accept = "application/json"; 14 httpWebRequest.Timeout = 15000; 15 httpWebRequest.AllowAutoRedirect = false; 16 //Bearer+空格 17 httpWebRequest.Headers.Add("Authorization", "Bearer " + token); 18 httpWebRequest.Credentials = CredentialCache.DefaultCredentials; 19 20 string result = null; 21 try 22 { 23 WebResponse response = httpWebRequest.GetResponse(); 24 Stream responseStream = response.GetResponseStream(); 25 if (responseStream != null) 26 { 27 using (StreamReader streamReader = new StreamReader(responseStream, Encoding.UTF8)) 28 { 29 result = streamReader.ReadToEnd(); 30 streamReader.Close(); 31 } 32 } 33 } 34 catch (Exception ex) 35 { 36 throw new Exception(ex.Message); 37 } 38 return result; 39 }View Code
