json - 如何在 jsonpath 中转义特殊字符冒号 (':' )

Question

JSON:

{
    "im:rating": {
        "label": "1"
    }
}

尝试在 groovy 中使用 Jsonpath如果我使用这个'$.im:rating'

显示如下错误

Caused by: com.nebhale.jsonpath.InvalidJsonPathExpressionException: Illegal

$['im:rating']

Selects the specified property in a parent object. Be sure to put single quotes around the property name.Tip: Use this notation if the property name contains special characters such as spaces, or begins with a character other than A..Za..z_.https://support.smartbear.com/alertsite/docs/monitors/api/endpoint/jsonpath.html
