| --- | |
| ## 🔧 Configuración para Android | |
| ### Opción A: Red Local (Recomendado) | |
| **URL Base:** `http://192.168.1.10:8000` | |
| **En tu app .NET MAUI:** | |
| ```csharp | |
| public static class ApiConfig | |
| { | |
| public static string BaseUrl = "http://192.168.1.10:8000"; | |
| } | |
| ``` | |
| **Requisitos:** | |
| - ✅ Ambos dispositivos en la misma red WiFi | |
| - ✅ Firewall permite puerto 8000 | |
| - ✅ API ejecutada con `--host 0.0.0.0` | |
| **Ventajas:** | |
| - Baja latencia | |
| - No depende de servicios externos | |
| - Máxima velocidad | |
| --- | |
| ### Opción B: Cloudflare Tunnel | |
| **URL Base:** Variable (cambia al reiniciar) | |
| **Para activar:** | |
| ```bash | |
| python start_tunnel.py | |
| ``` | |
| **URL se guarda en:** `tunnel_url.txt` | |
| **Ventajas:** | |
| - ✅ Funciona desde cualquier lugar del mundo | |
| - ✅ HTTPS automático | |
| - ✅ No requiere misma red | |
| **Desventajas:** | |
| - URL expira al detener el túnel | |
| - Depende de servicio externo | |
| --- | |
| ### Opción C: Emulador Android Studio | |
| **URL Base:** `http://10.0.2.2:8000` | |
| El emulador de Android usa `10.0.2.2` para referirse al localhost del equipo host. | |
| --- | |

| ## 🔐 Flujo de Autenticación (Android) | |
| ### 1. Registro | |
| ```csharp | |
| var response = await client.PostAsync("/auth/register", new StringContent( | |
| JsonConvert.SerializeObject(new { | |
| username = "miusuario", | |
| email = "mi@email.com", | |
| password = "mipassword" | |
| }), | |
| Encoding.UTF8, | |
| "application/json" | |
| )); | |
| ``` | |
| ### 2. Login | |
| ```csharp | |
| var content = new FormUrlEncodedContent(new[] | |
| { | |
| new KeyValuePair<string, string>("username", "miusuario"), | |
| new KeyValuePair<string, string>("password", "mipassword"), | |
| new KeyValuePair<string, string>("device_id", "android_unico_id"), | |
| new KeyValuePair<string, string>("device_name", "Samsung Galaxy S21") | |
| }); | |
| var response = await client.PostAsync("/auth/token", content); | |
| var token = JsonConvert.DeserializeObject<LoginResponse>(await response.Content.ReadAsStringAsync()).AccessToken; | |
| ``` | |
| ### 3. Peticiones Autenticadas | |
| ```csharp | |
| client.DefaultRequestHeaders.Authorization = | |
| new AuthenticationHeaderValue("Bearer", token); | |
| // Ahora puedes llamar a endpoints protegidos | |
| var profile = await client.GetAsync("/auth/users/me"); | |
| ``` | |
| --- | |
| ## 🎯 Ejemplo de Uso Completo (Android) | |
| ```csharp | |
| public class MelodixApi | |
| { | |
| private readonly HttpClient _client; | |
| private string _token; | |
| public MelodixApi() | |
| { | |
| _client = new HttpClient | |
| { | |
| BaseAddress = new Uri("http://192.168.1.10:8000") | |
| }; | |
| } | |
| // 1. Login | |
| public async Task<bool> LoginAsync(string username, string password, string deviceId, string deviceName) | |
| { | |
| var content = new FormUrlEncodedContent(new[] | |
| { | |
| new KeyValuePair<string, string>("username", username), | |
| new KeyValuePair<string, string>("password", password), | |
| new KeyValuePair<string, string>("device_id", deviceId), | |
| new KeyValuePair<string, string>("device_name", deviceName) | |
| }); | |

| { new StringContent(stems.ToString()), "stems" }, | |
| { new StringContent("android_device_001"), "device_id" } | |
| }; | |
| var response = await _client.PostAsync("/songs/upload", formData); | |
| if (response.IsSuccessStatusCode) | |
| { | |
| var result = JsonConvert.DeserializeObject<UploadResult>(await response.Content.ReadAsStringAsync()); | |
| return result.CeleryId; // ID para consultar estado | |
| } | |
| return null; | |
| } | |
| // 3. Consultar estado | |
| public async Task<ProcessStatus> CheckStatusAsync(string celeryId) | |
| { | |

| return JsonConvert.DeserializeObject<ProcessStatus>(await response.Content.ReadAsStringAsync()); | |
| } | |
| return null; | |
| } | |
| // 4. Obtener historial | |
| public async Task<List<SongHistory>> GetHistoryAsync(int limit = 20) | |
| { | |
| var response = await _client.GetAsync($"/songs/history?limit={limit}"); | |
| if (response.IsSuccessStatusCode) | |

| ## 🐛 Problemas Conocidos | |
| ### 1. Túnel Cloudflare Expira | |
| **Síntoma:** URL en `tunnel_url.txt` no funciona después de reiniciar. | |
| **Solución:** Reiniciar el túnel: | |
| ```bash | |
| python start_tunnel.py | |
| ``` | |
| ### 2. Firewall de Windows | |
| **Síntoma:** Android no puede conectar a `192.168.1.10:8000` | |
| **Solución:** Permitir puerto 8000 en Firewall de Windows: | |
| ```powershell | |
| netsh advfirewall firewall add rule name="Melodix API" dir=in action=allow protocol=TCP localport=8000 | |
| ``` | |
| ### 3. Celery se Detiene en Windows | |
| **Síntoma:** Worker de Celery deja de responder. | |
| **Solución:** Presionar una tecla en la ventana de Celery o reiniciar: | |
| ```bash | |
| celery -A tasks worker --loglevel=info -P solo | |
| ``` | |
| --- | |
| ## 📝 Recomendaciones | |
| ### Para Producción | |
| 1. **Base de Datos:** Migrar a PostgreSQL | |
| ```env | |
| DATABASE_URL=postgresql://usuario:password@localhost:5432/melodix_db | |
| ``` | |
| 2. **Redis con Contraseña:** | |
| ```env | |
| REDIS_URL=redis://:password_redis@localhost:6379/0 | |
| ``` | |
| 3. **SECRET_KEY Fuerte:** | |
| ```bash | |
| python -c "import secrets; print(secrets.token_urlsafe(32))" | |
| ``` | |
| 4. **HTTPS:** Usar Cloudflare Tunnel o reverse proxy con Let's Encrypt | |
| 5. **Limpieza Automática:** Programar `cleanup.py` diariamente | |
| ### Para Desarrollo | |
| 1. **Usar Red Local:** Más rápido y estable que Cloudflare | |
| 2. **Swagger UI:** http://localhost:8000/docs para probar endpoints | |
| 3. **Logs:** Revisar `logs/melodix.log` para debugging | |
