如何使用terraform cloud API调用传递数组和映射

provider "terraform" {
  hostname = "app.terraform.io"
  organization = "<your_organization>"
  token = "<your_api_token>"
}

resource "null_resource" "example" {
  provisioner "local-exec" {
    command = <<-EOT
      curl \
        --header "Authorization: Bearer ${var.token}" \
        --header "Content-Type: application/vnd.api+json" \
        --request PATCH \
        --data '{
          "data": {
            "attributes": {
              "variables": {
                "example_variable": ${jsonencode(var.example_variable)},
                "example_map": ${jsonencode(var.example_map)}
              }
            }
          }
        }' \
        https://app.terraform.io/api/v2/workspaces/${data.terraform_remote_state.workspace.outputs.workspace_id}
    EOT
  }
}

terraform init
terraform apply
