我试过这里给出的例子.
https://developers.google.com/sheets/quickstart/java
它给了我这个例外 –
Exception in thread "main" com.google.api.client.auth.oauth2.TokenResponseException: 401 Unauthorized
at com.google.api.client.auth.oauth2.TokenResponseException.from(TokenResponseException.java:105)
at com.google.api.client.auth.oauth2.TokenRequest.executeUnparsed(TokenRequest.java:287)
at com.google.api.client.auth.oauth2.TokenRequest.execute(TokenRequest.java:307)
at com.google.api.client.auth.oauth2.Credential.executeRefreshToken(Credential.java:570)
at com.google.api.client.auth.oauth2.Credential.refreshToken(Credential.java:489)

at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:469)
at SheetsQuickstart.main(SheetsQuickstart.java:106)
我已经给了它所有必要的许可.
我正在使用表api版本v4
Update –
如果我在示例中传递电子邮件ID而不是用户,则它会给我这个响应.
变化 –
public static Credential authorize() throws IOException {
// Load client secrets.
InputStream in =
SheetsQuickstart.class.getResourceAsStream("/client_secret.json");
GoogleClientSecrets clientSecrets =
GoogleClientSecrets.load(JSON_FACTORY,new InputStreamReader(in));
// Build flow and trigger user authorization request.
GoogleAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow.Builder(
HTTP_TRANSPORT,JSON_FACTORY,clientSecrets,SCOPES)
.setDataStoreFactory(DATA_STORE_FACTORY)
.setAccessType("offline")
.build();
//Changed Part.
Credential credential = new AuthorizationCodeInstalledApp(
flow,new LocalServerReceiver()).authorize("test@gmail.com");
System.out.println(
"Credentials saved to " + DATA_STORE_DIR.getAbsolutePath());
return credential;
}

最佳答案
首先,请确保您正确遵循quickstart guide中的步骤,尤其是在开发人员控制台中启用Sheets API.
现在针对Error TokenResponseException：401 Unauthorized,基于此thread,在使用访问令牌进行API调用时导致该错误的常见原因是：
>过期访问令牌(最常见)
>开发人员意外禁用了API(不常见)
>用户撤销令牌(罕见)
有时,HTTP 4xx的响应主体中存在更多解释.例如,在Java客户端中,您应该记录错误,因为它将有助于排除故障：
try {
// Make your Google API call
} catch (GoogleJsonResponseException e) {
GoogleJsonError error = e.getDetails();
// Print out the message and errors
}
每当您获得HTTP 4xx并记录该响应时,您可以在此处获取现有代码并进行API调用.这将返回一些有用的信息.
如果令牌无效,您可以按照以下步骤操作.
>从数据存储区或数据库中删除访问令牌.
>使用刷新令牌获取新的访问令牌(如果您使用刷新令牌)
>尝试再次进行API调用.如果它有效,那你很好！如果不 …
>根据tokenInfo API检查访问令牌
>如果它仍然无效,请做一个完整的reauth
