How to Deserialize Dynamic Nested JSON Structures in Go?

Decoding Nested Dynamic JSON Structures in Go

In Go, deserializing JSON data with nested dynamic structures can be challenging. A recent query illustrates this issue:

{
    "status": "OK",
    "status_code": 100,
    "sms": {
        "79607891234": {
            "status": "ERROR",
            "status_code": 203,
            "status_text": "Нет текста сообщения"
        },
        "79035671233": {
            "status": "ERROR",
            "status_code": 203,
            "status_text": "Нет текста сообщения"
        },
        "79105432212": {
            "status": "ERROR",
            "status_code": 203,
            "status_text": "Нет текста сообщения"
        }
    },
    "balance": 2676.18
}

To deserialize such data, we need to use a map to model the dynamic list of SMS statuses. Here's the modified code:

type SMSPhone struct {
    Status     string `json:"status"`
    StatusCode int    `json:"status_code"`
    StatusText string `json:"status_text"`
}

type SMSSendJSON struct {
    Status     string              `json:"status"`
    StatusCode int                 `json:"status_code"`
    Sms        map[string]SMSPhone `json:"sms"`
    Balance    float64             `json:"balance"`
}

Now, Unmarshaling the JSON data with this modified struct:

var result SMSSendJSON

if err := json.Unmarshal([]byte(src), &result); err != nil {
    panic(err)
}
fmt.Printf("%+v", result)

Will correctly deserialize the dynamic nested structures, resulting in:

{Status:OK StatusCode:100 Sms:map[79035671233:{Status:ERROR StatusCode:203 StatusText:Нет текста сообщения} 79105432212:{Status:ERROR StatusCode:203 StatusText:Нет текста сообщения} 79607891234:{Status:ERROR StatusCode:203 StatusText:Нет текста сообщения}] Balance:2676.18}

The keys in the result.Sms map correspond to the dynamic phone numbers, and their values are the respective SMS statuses.
