Handling JSON Data with Dynamic Keys in Go: implementing Marshaling and Unmarshaling
I'm maintaining legacy code that I'm attempting to set up I'm currently working with a scenario while working with JSON data that has dynamic keys in Go. Specifically, I have a JSON object where the keys can vary each time the API is called, and I'm trying to unmarshal it into a map. However, I'm working with an behavior when the keys contain special characters, which leads me to believe that my unmarshaling logic may need refinement. Here's an example of the JSON structure I'm dealing with: ```json { "user_1": { "name": "Alice", "age": 30 }, "user_2!": { "name": "Bob", "age": 25 } } ``` I attempted to unmarshal this JSON into a `map[string]map[string]interface{}` like this: ```go package main import ( "encoding/json" "fmt" ) func main() { jsonData := []byte(`{ "user_1": {"name": "Alice", "age": 30}, "user_2!": {"name": "Bob", "age": 25} }`) var result map[string]map[string]interface{} err := json.Unmarshal(jsonData, &result) if err != nil { fmt.Println("behavior unmarshaling JSON:", err) } fmt.Println(result) } ``` When I run this code, I get the output: ``` behavior unmarshaling JSON: json: want to unmarshal string into Go value of type map[string]interface {} ``` I suspect that the scenario could be related to how Go handles special characters in keys. I've also read that using `interface{}` can sometimes cause unexpected behavior when you don't know the exact structure of the data. I tried using `map[string]interface{}` for the outer layer, but I still encountered the same scenario. My goal is to retrieve the data dynamically regardless of the special characters in the keys. How can I correctly unmarshal this JSON structure in Go? Any insights or best practices would be highly appreciated! For context: I'm using Go on Windows. Any suggestions would be helpful.
