Is there any convenience way to get JSON element without type assertion? : I am mainly a python programmer and new Golang.

There are some inconvenience while processing JSON response from a web server.

For example, I don't know the data structure (and don't want to model it) of the JSON in advanced, and just want to get the value from it!

So, for Python, I can just write

    value = response["body"][4]["data"]["uid"]  //response is a dictionary
But for Golang, I need to do the assertion for every element!

    value := response["body"].([]interface{})[4].(map[string]interface{})["data"].(map[string]interface{})["uid"]
    //response is a map[string]interface{}

This is what I write in golang to get the value I need. Do you have any suggestion on it? It there any useful tips for this kind of case? Thank you.
