通过API 1.1使用Twitter OAuth，无需第三方库

我在使用GET状态/ user_timeline和OAuth时遇到了麻烦。通过API 1.1使用Twitter OAuth，无需第三方库

我是新来的推特&编程。我在文档中看到的大多数帮助都是针对POST。

早些时候，我是用：http://api.twitter.com/1/statuses/user_timeline.json?screen_name=userid

现在根据新的API，我试图使用方法：https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=userid。但我得到“远程服务器返回错误：（400）错误请求”。

我在dev.twitter.com上发了一个应用程序。我也设法生成了一个签名。现在我不知道如何发布签名并获得输出。我使用C＃Web表单.net 3.5。我不能使用像twitterizer这样的第三方库。

我跟着Get twitter public timeline, json+C#, no 3rd party libraries的线程和两个跟进线程。出事了。我假设它与API 1.1有关。

在这里你去（改变“更新我”一节）：

 // oauth application keys 
     var oauth_token = "update me"; 
     var oauth_token_secret = "update me"; 
     var oauth_consumer_key = "update me"; 
     var oauth_consumer_secret = "update me"; 

     // oauth implementation details 
     var oauth_version = "1.0"; 
     var oauth_signature_method = "HMAC-SHA1"; 

     // unique request details 
     var oauth_nonce = Convert.ToBase64String(
      new ASCIIEncoding().GetBytes(DateTime.Now.Ticks.ToString())); 
     var timeSpan = DateTime.UtcNow 
      - new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc); 
     var oauth_timestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString(); 

     // message api details 
     var status = "Updating status via REST API if this works"; 
     var resource_url = "https://api.twitter.com/1.1/statuses/user_timeline.json"; 
     var screen_name = "updateme"; 
     // create oauth signature 
     var baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" + 
         "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&screen_name={6}"; 

     var baseString = string.Format(baseFormat, 
            oauth_consumer_key, 
            oauth_nonce, 
            oauth_signature_method, 
            oauth_timestamp, 
            oauth_token, 
            oauth_version, 
            Uri.EscapeDataString(screen_name) 
            ); 

     baseString = string.Concat("GET&", Uri.EscapeDataString(resource_url), "&", Uri.EscapeDataString(baseString)); 

     var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_secret), 
           "&", Uri.EscapeDataString(oauth_token_secret)); 

     string oauth_signature; 
     using (HMACSHA1 hasher = new HMACSHA1(ASCIIEncoding.ASCII.GetBytes(compositeKey))) 
     { 
      oauth_signature = Convert.ToBase64String(
       hasher.ComputeHash(ASCIIEncoding.ASCII.GetBytes(baseString))); 
     } 

     // create the request header 
     var headerFormat = "OAuth oauth_nonce=\"{0}\", oauth_signature_method=\"{1}\", " + 
          "oauth_timestamp=\"{2}\", oauth_consumer_key=\"{3}\", " + 
          "oauth_token=\"{4}\", oauth_signature=\"{5}\", " + 
          "oauth_version=\"{6}\""; 

     var authHeader = string.Format(headerFormat, 
           Uri.EscapeDataString(oauth_nonce), 
           Uri.EscapeDataString(oauth_signature_method), 
           Uri.EscapeDataString(oauth_timestamp), 
           Uri.EscapeDataString(oauth_consumer_key), 
           Uri.EscapeDataString(oauth_token), 
           Uri.EscapeDataString(oauth_signature), 
           Uri.EscapeDataString(oauth_version) 
         ); 


     // make the request 

     ServicePointManager.Expect100Continue = false; 

     var postBody = "screen_name=" + Uri.EscapeDataString(screen_name);// 
     resource_url += "?" + postBody; 
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(resource_url); 
     request.Headers.Add("Authorization", authHeader); 
     request.Method = "GET"; 
     request.ContentType = "application/x-www-form-urlencoded"; 


     WebResponse response = request.GetResponse(); 
     string responseData = new StreamReader(response.GetResponseStream()).ReadToEnd();

这是否适用于POST和流API？我已经使用这个，并继续获得401未经授权。 – 2013-04-03 17:39:13
