Halaman ini menjelaskan cara menetapkan label
Field
pada satu
file Google Drive.
Untuk menambahkan metadata ke file dengan menetapkan label file, gunakan metode
files.modifyLabels
. Isi permintaan
berisi instance
ModifyLabelsRequest
untuk mengubah kumpulan label pada file. Permintaan dapat berisi beberapa modifikasi yang diterapkan secara atomik. Artinya, jika ada modifikasi yang tidak
valid, seluruh update akan gagal dan tidak ada perubahan (yang berpotensi
bergantung) yang diterapkan.
ModifyLabelsRequest
berisi instance
LabelModification
yang merupakan modifikasi pada label di file. Kolom ini juga dapat berisi instance
dari
FieldModification
yang merupakan modifikasi pada kolom label.
Jika berhasil, isi
respons akan berisi
label yang ditambahkan atau diperbarui oleh permintaan. Objek ini ada dalam
objek modifiedLabels
berjenis Label
.
Contoh
Contoh kode berikut menunjukkan cara menggunakan fieldId
kolom teks untuk menetapkan
nilai Field
ini pada
file. Saat label Field
ditetapkan pada file untuk pertama kalinya, label tersebut akan diterapkan ke file. Kemudian, Anda dapat membatalkan setelan satu kolom atau menghapus semua kolom yang terkait dengan
label. Untuk mengetahui informasi selengkapnya, lihat Membatalkan setelan kolom label pada
file dan Menghapus label dari
file.
Java
LabelFieldModification fieldModification =
new LabelFieldModification().setFieldId("FIELD_ID").setSetTextValues(ImmutableList.of("VALUE"));
ModifyLabelsRequest modifyLabelsRequest =
new ModifyLabelsRequest()
.setLabelModifications(
ImmutableList.of(
new LabelModification()
.setLabelId("LABEL_ID")
.setFieldModifications(ImmutableList.of(fieldModification))));
ModifyLabelsResponse modifyLabelsResponse = driveService.files().modifyLabels("FILE_ID", modifyLabelsRequest).execute();
Python
field_modification = {'fieldId':'FIELD_ID','setTextValues':['VALUE']}
label_modification = {'labelId':'LABEL_ID', 'fieldModifications':[field_modification]}
modified_labels = drive_service.files().modifyLabels(fileId="FILE_ID", body = {'labelModifications' : [label_modification]}).execute()
Node.js
/**
* Set a label with a text field on a Drive file
* @return{obj} updated label data
**/
async function setLabelTextField() {
// Get credentials and build service
// TODO (developer) - Use appropriate auth mechanism for your app
const {GoogleAuth} = require('google-auth-library');
const {google} = require('googleapis');
const auth = new GoogleAuth({scopes: 'https://www.googleapis.com/auth/drive'});
const service = google.drive({version: 'v3', auth});
const fieldModification = {
'fieldId': 'FIELD_ID',
'setTextValues': ['VALUE'],
};
const labelModification = {
'labelId': 'LABEL_ID',
'fieldModifications': [fieldModification],
};
const labelModificationRequest = {
'labelModifications': [labelModification],
};
try {
const updateResponse = await service.files.modifyLabels({
fileId: 'FILE_ID',
resource: labelModificationRequest,
});
return updateResponse;
} catch (err) {
// TODO (developer) - Handle error
throw err;
}
}
Ganti kode berikut:
- FIELD_ID:
fieldId
kolom yang akan diubah. Untuk menemukan
fieldId
, ambil label menggunakan
Google Drive Labels API.
- VALUE:
value
baru untuk kolom ini.
- LABEL_ID:
labelId
label yang akan diubah.
- FILE_ID:
fileId
file yang labelnya diubah.
Catatan
- Untuk menyetel label tanpa kolom, terapkan
labelModifications
tanpa
fieldModifications
.
- Untuk menetapkan nilai opsi kolom pilihan, gunakan ID
Choice
nilai
yang bisa Anda dapatkan dengan mengambil skema label di
Drive Labels API.
- Hanya
Field
yang mendukung daftar nilai yang dapat memiliki beberapa nilai yang ditetapkan,
jika tidak, Anda akan menerima respons error 400: Bad Request
.
- Tetapkan jenis nilai yang tepat untuk
Field
yang dipilih (seperti bilangan bulat, teks, pengguna, dll.), atau Anda akan menerima respons error 400: Bad Request
.
Anda dapat mengambil jenis data kolom menggunakan
Drive Labels API.

The\n[request body](/workspace/drive/api/reference/rest/v2/files/modifyLabels#request-body)\ncontains an instance of\n[`ModifyLabelsRequest`](/workspace/drive/api/reference/rest/v2/files/modifyLabels#modifylabelsrequest)\nto modify the set of labels on a file. The request might contain several\nmodifications that are applied atomically. That is, if any modifications aren't\nvalid, then the entire update is unsuccessful and none of the (potentially\ndependent) changes are applied.\n\nThe `ModifyLabelsRequest` contains an instance of\n[`LabelModification`](/workspace/drive/api/reference/rest/v2/files/modifyLabels#labelmodification)\nwhich is a modification to a label on a file. It might also contain an instance\nof\n[`FieldModification`](/workspace/drive/api/reference/rest/v2/files/modifyLabels#fieldmodification)\nwhich is a modification to a label's field.\n\nIf successful, the [response\nbody](/workspace/drive/api/reference/rest/v2/files/modifyLabels#response-body) contains\nthe labels added or updated by the request. These exist within a\n`modifiedLabels` object of type [`Label`](/workspace/drive/api/reference/rest/v2/Label).\n\nExample\n-------\n\nThe following code sample shows how to use the `fieldId` of a text field to set\na value for this [`Field`](/workspace/drive/labels/reference/rest/v2/labels#field) on a\nfile. When a label `Field` is initially set on a file, it applies the label to\nthe file. You can then unset a single field or remove all fields associated with\nthe label. For more information, see [Unset a label field on a\nfile](/workspace/drive/api/guides/unset-label) and [Remove a label from a\nfile](/workspace/drive/api/guides/remove-label). \n\n### Java\n\n LabelFieldModification fieldModification =\n new LabelFieldModification().setFieldId(\"\u003cvar translate=\"no\"\u003eFIELD_ID\u003c/var\u003e\").setSetTextValues(ImmutableList.of(\"\u003cvar translate=\"no\"\u003eVALUE\u003c/var\u003e\"));\n\n ModifyLabelsRequest modifyLabelsRequest =\n new ModifyLabelsRequest()\n .setLabelModifications(\n ImmutableList.of(\n new LabelModification()\n .setLabelId(\"\u003cvar translate=\"no\"\u003eLABEL_ID\u003c/var\u003e\")\n .setFieldModifications(ImmutableList.of(fieldModification))));\n\n ModifyLabelsResponse modifyLabelsResponse = driveService.files().modifyLabels(\"\u003cvar translate=\"no\"\u003eFILE_ID\u003c/var\u003e\", modifyLabelsRequest).execute();\n\n### Python\n\n field_modification = {'fieldId':'\u003cvar translate=\"no\"\u003eFIELD_ID\u003c/var\u003e','setTextValues':['\u003cvar translate=\"no\"\u003eVALUE\u003c/var\u003e']}\n label_modification = {'labelId':'\u003cvar translate=\"no\"\u003eLABEL_ID\u003c/var\u003e', 'fieldModifications':[field_modification]}\n\n modified_labels = drive_service.files().modifyLabels(fileId=\"\u003cvar translate=\"no\"\u003eFILE_ID\u003c/var\u003e\", body = {'labelModifications' : [label_modification]}).execute()\n\n### Node.js\n\n /**\n * Set a label with a text field on a Drive file\n * @return{obj} updated label data\n **/\n async function setLabelTextField() {\n // Get credentials and build service\n // TODO (developer) - Use appropriate auth mechanism for your app\n\n const {GoogleAuth} = require('google-auth-library');\n const {google} = require('googleapis');\n\n const auth = new GoogleAuth({scopes: 'https://www.googleapis.com/auth/drive'});\n const service = google.drive({version: 'v3', auth});\n const fieldModification = {\n 'fieldId': '\u003cvar translate=\"no\"\u003eFIELD_ID\u003c/var\u003e',\n 'setTextValues': ['\u003cvar translate=\"no\"\u003eVALUE\u003c/var\u003e'],\n };\n const labelModification = {\n 'labelId': '\u003cvar translate=\"no\"\u003eLABEL_ID\u003c/var\u003e',\n 'fieldModifications': [fieldModification],\n };\n const labelModificationRequest = {\n 'labelModifications': [labelModification],\n };\n try {\n const updateResponse = await service.files.modifyLabels({\n fileId: '\u003cvar translate=\"no\"\u003eFILE_ID\u003c/var\u003e',\n resource: labelModificationRequest,\n });\n return updateResponse;\n } catch (err) {\n // TODO (developer) - Handle error\n throw err;\n }\n }\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003eFIELD_ID\u003c/var\u003e: The `fieldId` of the field to modify.
