如何将杜松子{proxy +}设置为杜松子酒和招摇的路径？

golang newb here ;)

I'm using gin, with an example API being:

// @Summary GET proxied request
// @Produce  json
// @Router /exampleapp/proxy/{proxy+} [get]
func getter(c *gin.Context) {
    handleRequest(c)
}

func main() {
    r := gin.Default()

    group := r.Group("/exampleapp")
    group.GET("/proxy/*path", getter)

    r.Run(":8088")
}

I am using swaggo/swag to generate a swagger file from the above annotations, I want it to output swagger.json like this:

"/exampleapp/proxy/{proxy+}": {
            "get": {
                "produces": [
                    "application/json"
                ],
                "summary": "GET proxied request"
            }
        }

but I can't get the + to escape correctly, currently getting

"/exampleapp/proxy/{proxy": {
            "get": {
                "produces": [
                    "application/json"
                ],
                "summary": "GET proxied request"
            }
        }

Have tried variations of \\, \+ but can't quite get it. Whats the correct way to escape that +?

This is so I can use proxying on AWS APIGW
