Azure golang SDK 将 AcrPull 角色分配给 AKS 群集

创建了AKS集群和ACR之后，我现在try 以编程方式授予AKS集群AcrPull角色. 目前，我正在try 使用Golang SDK中的RoleAssignmentsClient.Create()函数来实现这一点.

以下是我到目前为止try 过的:

AcrPullDefinitionID := "/providers/Microsoft.Authorization/roleDefinitions/7f951dda-4ed3-4680-a7ca-43fe172d538d"
//         pulled that ^ off of: https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles#acrpull

providerNamespace := "/providers/Microsoft.ContainerService/managedClusters/"

scope := "/subscriptions/" + subscriptionID + "/resourceGroups/" + resourceGroupName + providerNamespace + resourceName
res, err := raClient.Create(ctx, scope, roleAssigmentName, armauthorization.RoleAssignmentCreateParameters{
        Properties: &armauthorization.RoleAssignmentProperties{
            PrincipalID:      to.Ptr(clientID),
            PrincipalType:    to.Ptr(armauthorization.PrincipalTypeServicePrincipal),
            RoleDefinitionID: to.Ptr("/subscriptions/" + subscriptionID + AcrPullDefinitionID),
    },
}, nil)

当我使用上面的值进行调用时，我得到以下错误:

for resource: {AKSClusterName} of type: /providers/Microsoft.ContainerService/managedClusters/
Unable to create roleAssignment: PUT https://management.azure.com/subscriptions/{subscriptionID}/resourceGroups/{resourceGroup}/providers/Microsoft.ContainerService/managedClusters/{AKSClusterName}/providers/Microsoft.Authorization/roleAssignments/providers/Microsoft.Authorization/roleDefinitions/7f951dda-4ed3-4680-a7ca-43fe172d538d

RESPONSE 405: 405 Method Not Allowed
ERROR CODE UNAVAILABLE
--------------------------------------------------------------------------------
{
  "message": "The requested resource does not support http method 'PUT'."
}
--------------------------------------------------------------------------------

我不确定这是一个概念上的误解，还是我只是错误地使用了API.

任何帮助都将不胜感激.谢谢!
