func myHandler(c *Context) { // Extract the value of the "myParam" key from the context myVal, ok := c.Params.Get("myParam") if !ok { // Handle the case where the parameter is not present } // Use the parameter value in some way // ... }In this example, we define a function called "myHandler" that takes a pointer to a Context object. Within the handler function, we use the Get method of the Params object to extract the value of the "myParam" key from the context. If the key is not present, we handle the error appropriately. Once we have the parameter value, we can use it in any way that makes sense for our application. Overall, the go github.com.grafana.grafana.pkg.middleware package provides a set of utility functions that can be very helpful when building web applications with Grafana. By including this package in your project, you can take advantage of these functions to make your code simpler and more maintainable.
