Java 使用Google Sheets Api时出错
你好!目前有两种方法可以获得第一个凭证,即该凭证是否能够正常使用Google Drive Api,并首次要求获得许可证:Java 使用Google Sheets Api时出错,java,google-api,google-sheets,Java,Google Api,Google Sheets,你好!目前有两种方法可以获得第一个凭证,即该凭证是否能够正常使用Google Drive Api,并首次要求获得许可证: private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance(); private static HttpTransport HTTP_TRANSPORT; private static FileDataStoreFactory DAT

然后,我使用这些方法获取可用文档的列表
Drive service = getDriveService();
// Print the names and IDs for up to 10 files.
FileList result = service.files().list()
.setPageSize(100)
.setFields("nextPageToken, files(id, name)")
.execute();
List<File> files = result.getFiles();
if (files == null || files.size() == 0) {
System.out.println("No files found.");
} else {
System.out.println("Files:");
for (File file : files) {
System.out.printf("%s (%s)\n", file.getName(), file.getId());
}
}
Drive service=getDriveService();
//打印最多10个文件的名称和ID。
FileList结果=service.files().list()
.setPageSize(100)
.setFields(“nextPageToken,文件(id,名称)”)
.execute();
List files=result.getFiles();
如果(files==null | | files.size()==0){
System.out.println(“未找到文件”);
}否则{
System.out.println(“文件:”);
用于(文件:文件){
System.out.printf(“%s(%s)\n”、file.getName()、file.getId());
}
}
它工作正常,但我需要进一步的工作,通过模拟直接使用表(Google Sheets Api),生成凭证并将可用表列表带到控制台:
InputStream in =
DriveQuickstart.class.getResourceAsStream("/client_secret.json");
GoogleClientSecrets clientSecrets =
GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
GoogleAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow.Builder(
HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
.setDataStoreFactory(DATA_STORE_FACTORY)
.setAccessType("offline")
.build();
Credential credential = new AuthorizationCodeInstalledApp(
flow, new LocalServerReceiver()).authorize("user");
System.out.println(
"\"Credentials saved to" + DATA_STORE_DIR.getAbsolutePath());
SpreadsheetService service = new SpreadsheetService("MyAppName");
service.setOAuth2Credentials(credential);
URL SPREADSHEET_FEED_URL = new URL(
"https://spreadsheets.google.com/feeds/spreadsheets/private/full");
SpreadsheetFeed feed = service.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class);
List<SpreadsheetEntry> spreadsheets = feed.getEntries();
for (SpreadsheetEntry spreadsheet : spreadsheets) {
System.out.println(spreadsheet.getTitle().getPlainText() + " " + spreadsheet.getId());
}
InputStream-in=
DriveQuickstart.class.getResourceAsStream(“/client_secret.json”);
谷歌客户机密=
load(JSON_工厂,新的InputStreamReader(in));
GoogleAuthorizationCodeFlow=
新的GoogleAuthorizationCodeFlow.Builder(
HTTP_传输、JSON_工厂、客户端机密、作用域)
.setDataStoreFactory(数据存储工厂)
.setAccessType(“脱机”)
.build();
凭证凭证=新授权代码已安装App(
流,新的LocalServerReceiver())。授权(“用户”);
System.out.println(
“\”凭证保存到“+数据存储\目录getAbsolutePath());
电子表格服务=新的电子表格服务(“MyAppName”);
服务。设置OAuth2Credentials(凭证);
URL电子表格\u提要\u URL=新URL(
"https://spreadsheets.google.com/feeds/spreadsheets/private/full");
SpreadsheetFeed=service.getFeed(电子表格\u feed\u URL,SpreadsheetFeed.class);
列表电子表格=feed.getEntries();
用于(电子表格输入电子表格:电子表格){
System.out.println(电子表格.getTitle().getPlainText()+“”+电子表格.getId());
}
但事实证明,当您创建电子表格提要错误的实例时:

请告诉我,问题出在哪里?还有一种通过其他方式获取凭据的方法,但每次不合适的O代码都需要手动操作。错误消息会准确地告诉您问题出在哪里。驱动器令牌的作用域错误。
