Gin bind to string in post body

So, my post request looks something like this:

fetch('/endpoint', {method: "POST", body: "my string"})

And, I'm trying to bind the body to a string like this:

var x string
c.Bind(&x)

But I'm getting the error reflect: NumField of non-struct type.

What is the appropriate way to get the body as a string, or do I need to just use the http Request.Body as a reader?

Was able to accomplish my goal with 3 lines:

    buf := new(bytes.Buffer)
    buf.ReadFrom(c.Request.Body)
    str := buf.String()

where str is the string containing the post body

Why is this not possible with Bind? Out of curiosity.

A possible alternative:

        // c *gin.Context
    data, _ := c.GetRawData()
    text := fmt.Sprintf("%s", data)
