# Chamadas Diretas da Bridge (Sem SDK)
Use este modo apenas quando voce nao puder usar `dtunnel-sdk`.
## Regras
- Objetos nativos ficam no `window` (`window.Dt...`).
- Metodos `execute/get/set` sao sincronos.
- Alguns retornos chegam em JSON string e precisam de parse manual.
- Eventos chegam via callbacks globais `Dt...Event`.
## Helpers recomendados
```js
function dtCall(objectName, methodName, ...args) {
const target = window[objectName];
if (!target || typeof target[methodName] !== 'function') return null;
try {
return target[methodName](...args);
} catch {
return null;
}
}
function dtCallJson(objectName, methodName, ...args) {
const raw = dtCall(objectName, methodName, ...args);
if (raw == null || typeof raw !== 'string') return raw ?? null;
try {
return JSON.parse(raw);
} catch {
return raw;
}
}
```
## Exemplo de chamadas
```js
// VPN
const vpnState = dtCall('DtGetVpnState', 'execute');
dtCall('DtExecuteVpnStart', 'execute');
dtCall('DtExecuteVpnStop', 'execute');
// Config
const configs = dtCallJson('DtGetConfigs', 'execute');
const defaultConfig = dtCallJson('DtGetDefaultConfig', 'execute');
dtCall('DtSetConfig', 'execute', 10);
// App
const appConfig = dtCallJson('DtGetAppConfig', 'execute', 'support_url');
// Android
const networkData = dtCallJson('DtGetNetworkData', 'execute');
const statusBarHeight = dtCall('DtGetStatusBarHeight', 'execute');
const navigationBarHeight = dtCall('DtGetNavigationBarHeight', 'execute');
dtCall('DtOpenExternalUrl', 'execute', 'https://dtunnel.com');
```
## Assinaturas dos callbacks globais
- `DtVpnStateEvent(state: string | null): void`
- `DtVpnStartedSuccessEvent(): void`
- `DtVpnStoppedSuccessEvent(): void`
- `DtNewLogEvent(): void`
- `DtNewDefaultConfigEvent(): void`
- `DtCheckUserStartedEvent(): void`
- `DtCheckUserResultEvent(dataJson: string | null): void`
- `DtCheckUserErrorEvent(message: string | null): void`
- `DtMessageErrorEvent(dataJson: string | null): void`
- `DtSuccessToastEvent(message: string | null): void`
- `DtErrorToastEvent(message: string | null): void`
- `DtNotificationEvent(dataJson: string | null): void`
## Exemplo de eventos sem SDK
```js
window.DtVpnStateEvent = function (state) {
console.log('vpnState:', state);
};
window.DtNotificationEvent = function (dataJson) {
const payload = dataJson ? JSON.parse(dataJson) : null;
console.log('notification:', payload);
};
```
