如何:新增明確的擁有者權限How-to: add explicit owner rights

使用 IpcCreateLicenseFromScratch 從頭開始建立授權時,您的應用程式應該明確加入「擁有者」權限。Your application should explicitly add "Owner" rights when creating a license from scratch using IpcCreateLicenseFromScratch.

必要條件Prerequisites

當您的應用程式正在使用 IpcCreateLicenseFromScratch 建立授權控制代碼時,它也必須明確授與擁有者完整權限 (權限)。When your application is creating a license handle using IpcCreateLicenseFromScratch, it must also grant the owner full rights (permissions) explicitly.

注意

使用內含 IPC_LI_OWNER 屬性的 IpcSetLicenseProperty 將使用者設為「擁有者」,並不會授與擁有者完整權限。Setting a user as "owner" using IpcSetLicenseProperty with the IPC_LI_OWNER property does not grant the owner full permissions.

下列範例程式碼僅代表涉及建立特定權限並將其加入指定授權中的步驟。The following example code only represents the steps involved in creating and adding the specific rights to a given license.

步驟 1:範例案例Step 1: Example scenario

此範例中,會在以 IpcCreateLicenseFromScratch 建立的授權中加入需要的權限。In this example, needed rights are added to a license created with IpcCreateLicenseFromScratch. 此範例顯示透過權限清單建立權限並指派給授權。The example shows the creation and assignment of the rights to the license through a rights list.

下列兩個權限會新增給這些使用者︰The following two rights are added to these users:

  • 指派給 joe@contoso.com 的「讀取」權限Read permissions assigned to joe@contoso.com
  • 指派給 mary 的 完整 許可權_kay@contoso.comFull permissions assigned to mary_kay@contoso.com

// Assign values to members of Rights structure

ownerRightForOwner.User.wszID = IPC_USER_ID_OWNER;
ownerRightForOwner.rgwszRights = rgwszOwnerRights;
ownerRightForOwner.cRights = 1;

// Create User Rights structure for Joe with Read permissions
IPC_USER_RIGHTS joeReadRight = {0};

joeReadRight.User.dwType = IPC_USER_TYPE_EMAIL;
joeReadRight.User.wszID = "joe@contoso.com";
joeReadRight.rgwszRights = rgwszReadRights;
joeReadRight.cRights = 1;

// Create User Rights structure for Mary Kay with Full permissions

// Assign values to members of Rights structure for Mary Kay
mary_kayFullRight.User.dwType = IPC_USER_TYPE_EMAIL;
