How to get all query parameters from go *gin.context object

I am looking at https://godoc.org/github.com/gin-gonic/gin documentation for a method which returns list of all the query parameters passed. There are methods which return value of a query parameter. Is there any method which returns list of all the query parameters passed ? It's ok if we don't get values. I am fetching the values of the query parameter using the following code. But this code can only check if the query parameter exists or not.

func myHandler(c *gin.Context) {
	// check for query params
	if queryParam, ok := c.GetQuery("startingIndex"); ok {
		if queryParam == "" {
			c.Header("Content-Type", "application/json")
			c.JSON(http.StatusNotFound,
				gin.H{"Error: ": "Invalid startingIndex on search filter!"})
			c.Abort()
			return
		}
	}
}

You should be able to do c.Request.URL.Query() which will return a Values which is a map[string][]string

you can get query parameters using :

c.Query("key") -> returns string
or
c.GetQuery("key") -> returns (string, bool->ok)

If you're talking about GET query params, you can retrieve them using:

c.Request.URL.Query()

You'll get back a Values type which is a map[string][]string

Carrying on from @ctcherry's answer...

func myAPIEndpoint(c *gin.Context) {
    paramPairs := c.Request.URL.Query()
    for key, values := range paramPairs {
	    fmt.Printf("key = %v, value(s) = %v\n", key, values)
    }
}

Keep in mind that a given key may contain multiple values, so your values is an array.
