## Ejemplo
|
|
|
|
```go
|
|
result, err := HttpPostJSON(
|
|
"https://api.example.com/users",
|
|
map[string]any{"name": "Alice", "role": "admin"},
|
|
map[string]string{"X-Api-Key": "secret"},
|
|
10*time.Second,
|
|
)
|
|
if err != nil {
|
|
return nil, err
|
|
}
|
|
fmt.Println(result["id"])
|
|
```

## Notas
|
|
|
|
Solo usa stdlib. El body acepta `any` y se serializa con json.Marshal. Headers custom se fusionan con Content-Type y Accept por defecto. El error incluye los primeros 200 bytes del body de respuesta.
