與Xamarin.Auth

Question

我試圖從Xamarin.iOS應用程序中調用VIMEO REST API，但我不斷收到401 VIMEO無效的OAuth簽名：The oauth_signature passed was not valid.

下面的代碼：

public async Task GetAll (string userId) 
{ 
    var request = OAuth1.CreateRequest (
     "GET", 
     new Uri ("http://vimeo.com/api/rest/v2"), 
     new Dictionary<string, string> { 
      {"user_id", userId}, 
      {"format", "json"}, 
      {"method", "vimeo.video.getAll"} 
     }, 
     CONSUMERKEY, CONSUMERSECRET, TOKENSECRET); 

    var response = await request.GetResponseAsync(); 
    using (var stream = response.GetResponseStream()) 
    using (var reader = new StreamReader (stream, System.Text.Encoding.UTF8)) { 
     Console.WriteLine (request.RequestUri); 
     Console.WriteLine(reader.ReadToEnd()); 
    } 
} 

該請求看起來是星期形成的，但它無論如何失敗。任何提示？

通過比較Xamarin.Auth生成的BaseString和http://oauth.googlecode.com/svn/code/javascript/example/signature.html生成的BaseString，我發現oath_token參數丟失。

我通過手動添加它固定我的問題：

public async Task GetAll (string userId) 
{ 
    var request = OAuth1.CreateRequest (
     "GET", 
     new Uri ("http://vimeo.com/api/rest/v2"), 
     new Dictionary<string, string> { 
      {"user_id", userId}, 
      {"format", "json"}, 
      {"method", "vimeo.video.getAll"}, 
      {"oauth_token", ACCESSTOKEN}, 
     }, 
     CONSUMERKEY, CONSUMERSECRET, TOKENSECRET); 

    var response = await request.GetResponseAsync(); 
    using (var stream = response.GetResponseStream()) 
    using (var reader = new StreamReader (stream, System.Text.Encoding.UTF8)) { 
     Console.WriteLine (request.RequestUri); 
     Console.WriteLine(reader.ReadToEnd()); 
    } 
}
