How do I decode JSON into structs in Go?

How do I decode JSON into structs in Go?

You can use the encoding/json package in Go. First, define your struct, then use json.Unmarshal to decode.

Can you show me an example of a struct and the JSON data?

Sure! Here's a simple example:

type Person struct {
    Name string `json:"name"`
    Age  int    `json:"age"`
}

jsonData := `{"name":"John", "age":30}`
var p Person
err := json.Unmarshal([]byte(jsonData), &p)

What if the JSON keys don't match the struct field names?

You can use struct tags to map JSON keys to struct fields. For example, json:"name" maps the JSON key "name" to the struct field Name.

Is there a way to handle nested JSON objects?

Yes, you can define nested structs for nested JSON objects. Just create a struct for the nested object and include it in the parent struct.
