如何將WCF rest api集成到應用程序中

Question

我正在尋找一個可以測試WCF rest api調用的C＃示例測試應用程序嗎？ 我在互聯網上找不到一個。 我有一些wcf端點的登錄憑證，以及我需要通過的。 有人可以指向我的示例測試休息api appln？

感謝

我想用WebClient應爲WCF REST服務工作（如果你需要，你可以使用憑證，請求頭，等）：

private void TestService() 
{ 
    try 
    { 
     string address = "<WCF REST service address>"; 
     WebClient client = new WebClient(); 
     string userName = "<user>"; 
     string password = "<password>"; 
     ICredentials creds = new NetworkCredential(userName, password); 
     client.Credentials = creds; 
     client.Headers[HttpRequestHeader.Authorization] = String.Format("Basic {0}:{1}", userName, password); 
     client.Headers[HttpRequestHeader.UserAgent] = @"Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)"; 
     Stream data = client.OpenRead(address); 
     StreamReader reader = new StreamReader(data); 
     string s = reader.ReadToEnd(); 
     Console.WriteLine(s); 
    } 
    catch (WebException ex) 
    { 
     Console.WriteLine(ex.Message); 
     if (ex.Response != null) 
     { 
      Stream strm = ex.Response.GetResponseStream(); 
      byte[] bytes = new byte[strm.Length]; 
      strm.Read(bytes, 0, (int)strm.Length); 
      string sResponse = System.Text.Encoding.ASCII.GetString(bytes); 
      Console.WriteLine(sResponse); 
     } 
    } 
} 

編輯：示例，它使用的Web應用程序表單認證。

如果Web應用程序允許匿名用戶，則前面的示例有效。如果不是（web.config中包含<deny users="?"/>和匿名訪問在IIS中啓用），需要兩個請求：

1. 請求到登錄頁面進行驗證;

2. 請求到實際的服務url。

auth cookie應傳遞給第二個請求（我們使用CookieContainer對象來實現此目的）。 第一次調用使用POST方法傳遞用戶名和密碼。因爲我的Web應用程序使用開箱即用的登錄控制，所以我需要傳遞視圖狀態，事件驗證等。您可以使用Fiddler或Chrome開發工具從Web瀏覽器獲取登錄過程中傳遞的表單數據。這是代碼：

private static void TestService() 
{ 
    try 
    { 
     string loginAddress = "<login url>"; 
     string serviceAddress = "<service url>"; 
     HttpWebRequest req = (HttpWebRequest)WebRequest.Create(loginAddress); 
     req.Method = "POST"; 
     string userName = "<user>"; 
     string password = "<password>"; 
     CookieContainer cc = new CookieContainer(); 
     req.CookieContainer = cc; 

     StringBuilder sb = new StringBuilder(); 
     sb.Append(@"__VIEWSTATE=<viewstate>"); 
     sb.Append(@"&__EVENTVALIDATION=<event validation>"); 
     sb.Append(@"&ctl00$MainContent$LoginUser$UserName={0}&ctl00$MainContent$LoginUser$Password={1}"); 
     sb.Append(@"&ctl00$MainContent$LoginUser$LoginButton=Log In"); 
     string postData = sb.ToString(); 
     postData = String.Format(postData, userName, password); 
     req.ContentType = "application/x-www-form-urlencoded"; 
     Encoding encoding = new ASCIIEncoding(); 
     byte[] requestData = encoding.GetBytes(postData); 
     req.ContentLength = requestData.Length; 

     //write the post data to the request 
     using (Stream reqStream = req.GetRequestStream()) 
     { 
      reqStream.Write(requestData, 0, requestData.Length); 
      reqStream.Flush(); 
     } 

     HttpWebResponse response = (HttpWebResponse)req.GetResponse(); //first call (login/authentication) 

     req = (HttpWebRequest)WebRequest.Create(serviceAddress); 
     req.CookieContainer = cc; //set the cookie container which contains the auth cookie 
     response = (HttpWebResponse)req.GetResponse(); //second call, the service request 
     Stream data = response.GetResponseStream(); 
     StreamReader reader = new StreamReader(data); 
     string s = reader.ReadToEnd(); 
     Console.WriteLine(s); 
    } 
    catch (WebException ex) 
    { 
     Console.WriteLine(ex.Message); 
     if (ex.Response != null) 
     { 
      Stream strm = ex.Response.GetResponseStream(); 
      byte[] bytes = new byte[strm.Length]; 
      strm.Read(bytes, 0, (int)strm.Length); 
      string sResponse = System.Text.Encoding.ASCII.GetString(bytes); 
      Console.WriteLine(sResponse); 
     } 
    } 
}

我喜歡做這種使用Fiddler測試（www.fiddler2.net）
