इस दस्तावेज़ में, किसी वाहन को मिटाने का तरीका बताया गया है. इसमें यह माना जाता है कि आपने Fleet Engine सेट अप किया है. Fleet Engine सेट अप करना लेख पढ़ें.
वाहन की जानकारी मिटाने के बारे में बुनियादी बातें
आपका सिस्टम, इन स्थितियों में किसी वाहन को मिटाने के लिए Fleet Engine का इस्तेमाल कर सकता है:
Fleet Engine API की जांच करते समय, क्लीनअप ऑपरेशन करने के लिए.
जिस वाहन की अब ज़रूरत नहीं है उसे तुरंत मिटाने के लिए.
किसी वाहन को मिटाने के लिए, gRPC या REST का इस्तेमाल करके अनुरोध भेजें.
अपने प्रोजेक्ट के सेवा खाते के लिए सही क्रेडेंशियल का इस्तेमाल करें. इसके बारे में Fleet Engine: सेवा खाते की भूमिकाएं लेख में बताया गया है.
उदाहरण: वाहन की जानकारी मिटाओ
Java
यहां दिए गए उदाहरण में, किसी वाहन को मिटाने के लिए Java gRPC लाइब्रेरी का इस्तेमाल करने का तरीका बताया गया है.
staticfinalStringPROJECT_ID="my-delivery-co-gcp-project";staticfinalStringVEHICLE_ID="vehicle-8241890";StringvehicleName="providers/"+PROJECT_ID+"/vehicles/"+VEHICLE_ID;VehicleServiceBlockingStubvehicleService=VehicleService.newBlockingStub(channel);// Delete Vehicle requestDeleteVehicleRequestdeleteVehicleRequest=DeleteVehicleRequest.newBuilder().setName(vehicleName).build();try{vehicleService.deleteVehicle(deleteVehicleRequest);}catch(StatusRuntimeExceptione){Statuss=e.getStatus();switch(s.getCode()){caseNOT_FOUND:// The vehicle doesn't exist.break;caseFAILED_PRECONDITION:// There are trip(s) that reference vehicle.break;casePERMISSION_DENIED:break;}return;}
REST
यहां दिए गए उदाहरण में, DeleteVehicle को कॉल करके REST का इस्तेमाल करके, Fleet Engine से किसी वाहन को मिटाने का तरीका बताया गया है.
# DELETE https://fleetengine.googleapis.com/v1/providers/<project_id>/vehicles/<vehicleId># Set JWT, PROJECT_ID, and VEHICLE_ID in the local environmentcurl-XDELETE-H"Authorization: Bearer ${JWT}"\"https://fleetengine.googleapis.com/v1/providers/${PROJECT_ID}/vehicles/${VEHICLE_ID}"
अगर मिटाने की कार्रवाई पूरी हो जाती है, तो एपीआई कोई जवाब नहीं देता.
गड़बड़ियां ठीक करना
किसी वाहन को मिटाते समय, आपको FAILED_PRECONDITION
गड़बड़ी दिख सकती है. ऐसा तब होता है, जब किसी यात्रा में उस वाहन का इस्तेमाल किया गया हो.
मिटाने की प्रक्रिया को आगे बढ़ाने के लिए:
वाहन के हिसाब से यात्राएं ढूंढने के लिए, SearchTrips पर कॉल करें.
मिली हुई हर यात्रा को मिटाने के लिए, DeleteTrip को कॉल करें.

See [Set up Fleet Engine](/maps/documentation/mobility/fleet-engine/essentials/set-up-fleet).\n\nVehicle deletion basics\n-----------------------\n\nYour system may use Fleet Engine to delete a vehicle in the following situations:\n\n- To perform cleanup operations while testing Fleet Engine APIs.\n- To immediately delete a Vehicle that is no longer required.\n\nTo delete a vehicle, send a request using either gRPC or REST.\n\n- `DeleteVehicle()` method: [gRPC](/maps/documentation/mobility/fleet-engine/reference/trips/rpc/maps.fleetengine.v1#maps.fleetengine.v1.VehicleService) or [REST](/maps/documentation/mobility/fleet-engine/reference/trips/rest/v1/providers.vehicles/delete)\n- `DeleteVehicleRequest` message: [gRPC](/maps/documentation/mobility/fleet-engine/reference/trips/rpc/maps.fleetengine.v1#deletevehiclerequest) only\n\nUse the appropriate credentials for the service account of your project as\ndescribed in [Fleet Engine: Service account roles](/maps/documentation/mobility/fleet-engine/essentials/set-up-fleet/service-accounts).\n| **Note:** Fleet Engine automatically deletes a vehicle after it has been inactive for a period of time. See [Vehicle re-use](/maps/documentation/mobility/fleet-engine/essentials/vehicles#vehicle_re-use).\n\nExample: delete vehicle\n-----------------------\n\n### Java\n\n\nThe following example shows how to use the [Java gRPC library](/maps/documentation/mobility/fleet-engine/reference/trips/rest/v1/providers.vehicles/delete) to delete a\nvehicle. \n\n static final String PROJECT_ID = \"my-delivery-co-gcp-project\";\n static final String VEHICLE_ID = \"vehicle-8241890\";\n\n String vehicleName = \"providers/\" + PROJECT_ID + \"/vehicles/\" + VEHICLE_ID;\n\n VehicleServiceBlockingStub vehicleService = VehicleService.newBlockingStub(channel);\n\n // Delete Vehicle request\n DeleteVehicleRequest deleteVehicleRequest = DeleteVehicleRequest.newBuilder()\n .setName(vehicleName)\n .build();\n\n try {\n vehicleService.deleteVehicle(deleteVehicleRequest);\n } catch (StatusRuntimeException e) {\n Status s = e.getStatus();\n switch (s.getCode()) {\n case NOT_FOUND: // The vehicle doesn't exist.\n break;\n case FAILED_PRECONDITION: // There are trip(s) that reference vehicle.\n break;\n case PERMISSION_DENIED:\n break;\n }\n return;\n }\n\n### REST\n\n\nThe following example shows how to delete a vehicle from Fleet Engine using REST by\nmaking a call to `DeleteVehicle`. \n\n # DELETE https://fleetengine.googleapis.com/v1/providers/\u003cproject_id\u003e/vehicles/\u003cvehicleId\u003e\n # Set JWT, PROJECT_ID, and VEHICLE_ID in the local environment\n curl -X DELETE -H \"Authorization: Bearer ${JWT}\" \\\n \"https://fleetengine.googleapis.com/v1/providers/${PROJECT_ID}/vehicles/${VEHICLE_ID}\"\n\nIf the delete operation is successful, the API returns an empty response.\n\nHandle errors\n-------------\n\nWhen deleting a vehicle, you might encounter a `FAILED_PRECONDITION`\nerror, in which case there are trip(s) that reference the vehicle.\nTo proceed with the deletion:\n\n1. Call `SearchTrips` to find trip(s) that reference the Vehicle.\n2. Call `DeleteTrip` to delete each of the found trip.\n\n| **Warning:** Ensure that the found trip(s) are no longer required. Once deleted, trip(s) cannot be recovered.\n\nWhat's next\n-----------\n\n- [Create an on-demand trip](/maps/documentation/mobility/fleet-engine/journeys/trips)"]]
