如何使用不使用SharePoint的外部Rest Web服務連接Office 365-SharePoint版本站點？

Question

我對SharePoint完全陌生。 我有一個不是使用SharePoint的Rest Web服務。 我可以使用此Rest Web服務連接SharePoint網站（Office 365-SharePoint版本）（如果是，那么如何實現它），還是需要使用SharePoint進行Rest服務？

如果有人可以幫助我，我將非常感激。 提前致謝。

有HttpWebRequest和HttpWebResponse類，使您可以調用REST服務。 之前，我曾使用它來訪問Parse.com（無法使用本機C＃接口）等服務以及我自己的Web服務。 這是來自MSDN的示例：

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create (args[0]);

        // Set some reasonable limits on resources used by this request
        request.MaximumAutomaticRedirections = 4;
        request.MaximumResponseHeadersLength = 4;
        // Set credentials to use for this request.
        request.Credentials = CredentialCache.DefaultCredentials;
        HttpWebResponse response = (HttpWebResponse)request.GetResponse ();

        Console.WriteLine ("Content length is {0}", response.ContentLength);
        Console.WriteLine ("Content type is {0}", response.ContentType);

        // Get the stream associated with the response.
        Stream receiveStream = response.GetResponseStream ();

        // Pipes the stream to a higher level stream reader with the required encoding format. 
        StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);

        Console.WriteLine ("Response stream received.");
        Console.WriteLine (readStream.ReadToEnd ());
        response.Close ();
        readStream.Close ();

這是我用來為用戶獲取朋友的一段代碼示例：

        public static WebExceptionStatus processResponse(HttpWebRequest response, out JsonValue values)
        {
            try
            {
                using (WebResponse stream = response.GetResponse())
                {
                    using (StreamReader reader = new StreamReader(stream.GetResponseStream()))
                    {
                        values = JsonObject.Parse (reader.ReadToEnd ());
                        return WebExceptionStatus.Success;
                    }
                }
            }
            catch (WebException exception) {
                values = null;
                return exception.Status;
            }
        }

...

        HttpWebRequest request = HttpWebRequest.Create ("myURL") as HttpWebRequest;
        request.Headers["SOMEH_HAEDER_VALUE"] = applicationID;
        request.Method = "GET";
        request.ContentType = "application/json";

        JsonValue values;
        status = RequestDriver.processResponse (request, out values);

        if (RequestDriver.HadException (status)) {
            ExceptionHandler.handleNetworkException(status);
        }

        if (values ["results"].Count == 0) {
            return null;
        }

        JsonValue userValue = values ["results"] [0];

        string name = RequestDriver.stripQuotes( userValue["Name"].ToString() );
        string objectId = RequestDriver.stripQuotes( userValue["objectId"].ToString() );

        User user = new User (name, email, objectId);
        return user;

您可以在SharePoint中使用REST服務來訪問列表和列表項之類的數據。 http://msdn.microsoft.com/library/office/dn292552.aspx

您將需要獲取訪問令牌以添加到請求中的Authorization標頭中。 若要獲取請求的令牌，必須在Azure Active Directory中注冊您的應用程序。 本文介紹了如何執行此操作http://msdn.microsoft.com/zh-cn/library/office/dn605894(v=office.15).aspx
