无法从iOS中的Google Drive获取文件 [英] Failed to get the files from Google Drive in IOS

问题描述

这是我的代码。

  GTLQueryDrive * query = [GTLQueryDrive queryForFilesList]; 
 query.q = [NSString stringWithFormat：@'％@'IN parents，@root]; 
 [self.driveService executeQuery：query completionHandler：^（GTLServiceTicket * ticket，GTLDriveFileList * files，NSError * error）
 {
 if（error == nil）{
 if（ self.driveFiles == nil）{
 self.driveFiles = [[NSMutableArray alloc] init]; 
} 
 [self.driveFiles removeAllObjects]; 
 [self.driveFiles addObjectsFromArray：files.items]; 
 [tbDownload reloadData]; 
} 
 else 
 {
 NSLog（@An error occurred：％@，error）; 
} 
}]; 
  

我使用这段代码得到错误。

n发生错误：错误域= com.google.GTLJSONRPCErrorDomain代码= 401无法完成操作（需要登录） UserInfo = 0x8f72a40 {error = Login Required，GTLStructuredError = GTLErrorObject 0x8f647a0：{message：Login Requiredcode：401 data：[1]}，NSLocalizedFailureReason =（需要登录）}

我已经在我的应用程序中使用谷歌驱动器登录。 您可能没有配置 GTLServiceDrive ，其中



示例代码：

GTMOAuth2Authentication （GTMOAuth2Authentication *）authResult错误：（NSError *）错误
{
if（error）{pre $
// Auth失败，处理错误
}
else {
self.driveService.authorizer = authResult;
}
}

Here is my code .

GTLQueryDrive *query = [GTLQueryDrive queryForFilesList];
query.q = [NSString stringWithFormat:@"'%@' IN parents", @"root"];
[self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,GTLDriveFileList *files, NSError *error)
{
    if (error == nil) {
        if (self.driveFiles == nil) {
            self.driveFiles = [[NSMutableArray alloc] init];
        }
        [self.driveFiles removeAllObjects];
        [self.driveFiles addObjectsFromArray:files.items];
        [tbDownload reloadData];
    } 
    else 
    {
        NSLog(@"An error occurred: %@", error);
    }
}]; 

I'm getting the error by using this code .

n error occurred: Error Domain=com.google.GTLJSONRPCErrorDomain Code=401 "The operation couldn’t be completed. (Login Required)" UserInfo=0x8f72a40 {error=Login Required, GTLStructuredError=GTLErrorObject 0x8f647a0: {message:"Login Required" code:401 data:[1]}, NSLocalizedFailureReason=(Login Required)}

I Already login with google drive in my app .

解决方案

You probably aren't configuring your GTLServiceDrive with the GTMOAuth2Authentication instance you get after successful authentication.

Example code:

- (void)viewController:(GTMOAuth2ViewControllerTouch *)viewController finishedWithAuth:(GTMOAuth2Authentication *)authResult error:(NSError *)error
{
    if (error) {
        // Auth failed, handle the error
    }
    else {
        self.driveService.authorizer = authResult;
    }
}
