如何：設定訂閱使用 Web 同步處理 (RMO 程式設計)

本主題中的程序，是設定合併式複寫的 Web 同步處理時所採取的第三個步驟。在啟用發行集及設定執行 Microsoft Internet Information Services (IIS) 的電腦之後，必須執行這個步驟。如需組態處理序的概觀，請參閱＜如何：為合併式複寫設定 Web 同步處理 (RMO 程式設計)＞。當您針對只能透過 HTTP 連接到發行者的訂閱者設定訂閱使用 Web 同步處理時，您必須適當地設定發行集。如需詳細資訊，請參閱＜如何：設定發行集來允許 Web 同步處理 (RMO 程式設計)＞。當您完成本主題中的程序之後，請同步處理您已建立的訂閱。如需詳細資訊，請參閱＜如何：同步處理提取訂閱 (RMO 程式設計)＞。

本主題將描述 Web 同步處理所需的參數。如需有關如何建立提取訂閱的詳細資訊，請參閱＜如何：建立提取訂閱 (RMO 程式設計)＞。

重要事項重要事項

用於 Web 同步處理之 Web 伺服器的 URL (例如 https://server.domain.com/directory/replisapi.dll) 會指定 replisapi.dll 的位置。如果設定伺服器針對安全通訊端層 (SSL) 使用預設通訊埠 443 以外的通訊埠，您也必須提供通訊埠：https://server.domain.com:PortNumber/directory/replisapi.dll。URL 中的伺服器名稱必須與建立憑證時所用的名稱相同。例如，在內部網路中，您可以透過 https://server/ 來存取 Web 伺服器。但是，如果在建立憑證時使用了完整名稱 (例如 https://server.domain.com/)，您就必須在 URL 中使用以下完整名稱：(https://server.domain.com/directory/replisapi.dll)。

設定訂閱使用 Web 同步處理

  1. 使用 ServerConnection 類別建立與訂閱者和發行者的連接。

  2. 使用步驟 1 中的發行者連接建立 MergePublication 類別的執行個體。

  3. (選擇性) 如果訂閱資料庫不存在，請使用 SQL Server Management Objects (SMO) Database 類別建立此資料庫。如需詳細資訊，請參閱＜建立、改變和移除資料庫＞。

  4. 建立 MergePullSubscription 類別的執行個體。

  5. 設定下列訂閱屬性：

  6. 呼叫 Create 方法。

  7. 使用步驟 2 中 MergePublication 的執行個體，呼叫 MakePullSubscriptionWellKnown 方法，以便向發行者註冊提取訂閱。

當您針對只能透過 HTTP 的 Web 伺服器連接到發行者的訂閱者來設定訂閱使用 Web 同步處理時

  1. 使用 ServerConnection 類別建立與訂閱者的連接。

  2. (選擇性) 如果訂閱資料庫不存在，可使用 SMO Database 類別建立此資料庫。如需詳細資訊，請參閱＜建立、改變和移除資料庫＞。

  3. 建立 MergePullSubscription 類別的執行個體。

  4. 設定下列訂閱屬性：

  5. 呼叫 Create 方法。
