如何使用MVC Power BI Embedded传递变量？

public ActionResult Index(string variable)
{
    ViewBag.Variable = variable;
    return View();
}

<div id="reportContainer"></div>

<script>
    var variable = '@ViewBag.Variable';

    var config = {
        type: 'report',
        tokenType: models.TokenType.Embed,
        accessToken: 'your_access_token',
        embedUrl: 'your_embed_url',
        id: 'your_report_id',
        filters: [
            {
                $schema: "http://powerbi.com/product/schema#basic",
                target: {
                    table: "your_table_name",
                    column: "your_column_name"
                },
                operator: "eq",
                values: [variable]
            }
        ]
    };

    var reportContainer = document.getElementById('reportContainer');
    var report = powerbi.embed(reportContainer, config);
</script>
