Question

我是Dialogflow的新手。如何要求用户提供位置许可，以及如果他们同意共享该位置，如何获得他们的当前位置。

因此，该想法是创建两个意图，一个用于请求许可，另一个用于获取用户许可。对于这两种意图，请启用Webhook。首先在实现中添加以下代码：

app.intent('location', (conv) => {

conv.data.requestedPermission = 'DEVICE_PRECISE_LOCATION';
return conv.ask(new Permission({
    context: 'to locate you',
    permissions: conv.data.requestedPermission,
})); 
});

对于第二个意图，请添加以下代码：

app.intent('user_info', (conv, params, permissionGranted) {
if (permissionGranted) {
    const {
        requestedPermission
    } = conv.data;
    if (requestedPermission === 'DEVICE_PRECISE_LOCATION') {

        const {
            coordinates
        } = conv.device.location;
        // const city=conv.device.location.city;

        if (coordinates) {
            return conv.close(`You are at ${coordinates.latitude}`);
        } else {
            // Note: Currently, precise locaton only returns lat/lng coordinates on phones and lat/lng coordinates
            // and a geocoded address on voice-activated speakers.
            // Coarse location only works on voice-activated speakers.
            return conv.close('Sorry, I could not figure out where you are.');
        }

    }
} else {
    return conv.close('Sorry, permission denied.');
}
});

并不是每个Dialogflow集成都通常提供“获取位置”，但是要在Google的“操作”中进行定位，您可以遵循this guide：

app.intent('Permission', (conv) => {
  const permissions = ['NAME'];
  let context = 'To address you by name';
  // Location permissions only work for verified users
  // https://developers.google.com/actions/assistant/guest-users
  if (conv.user.verification === 'VERIFIED') {
    // Could use DEVICE_COARSE_LOCATION instead for city, zip code
    permissions.push('DEVICE_PRECISE_LOCATION');
    context += ' and know your location';
  }
  const options = {
    context,
    permissions,
  };
  conv.ask(new Permission(options));
});

获得许可后，您可以在下一个处理程序中对其进行处理：

app.intent('Permission Handler', (conv, params, confirmationGranted) => {
  // Also, can access latitude and longitude
  // const { latitude, longitude } = location.coordinates;
  const {location} = conv.device;
  const {name} = conv.user;
  if (confirmationGranted && name && location) {
    conv.ask(`Okay ${name.display}, I see you're at ` +
      `${location.formattedAddress}`);
  } else {
    conv.ask(`Looks like I can't get your information.`);
  }
  conv.ask(`Would you like to try another helper?`);
  conv.ask(new Suggestions([
    'Confirmation',
    'DateTime',
    'Place',
  ]));
});
