Drive API 404 Error

[Sergei Kvasov]

Hi guys, 

I'm working on iOS app to manage Google Drive. Previously the app were using GoogleAPIClient/Drive library to access Google Drive, but now the library is deprecated and I'm trying to replace it with a new one  - GoogleAPIClientForREST. After successful login to my Google Account with GoogleSignIn library I'm trying to make search request to Google Drive with GoogleAPIClientForREST. After any request I get an error: An error occurred: Error Domain=com.google.HTTPStatus Code=404 "Not Found". No other details in log. Any idea?

Below code of my request:

- (void) searchRootFolder: (CompletionSearch) completionSearch

{

    NSString *parentId = @"root";

    

    GTLRDriveQuery_FilesList *query = [GTLRDriveQuery_FilesList query];

    query.q = [NSString stringWithFormat:@"'%@' in parents and trashed != true and '%@' in owners and name = '%@'", parentId, self.client.authenticator.usermail, [NSBundle appName]];

    query.orderBy = @"modifiedTime desc";

    query.pageSize = 1000;

    query.fields = kQueryFieldsFolder;

    

    [[self driveService] executeQuery:query completionHandler:^(GTLRServiceTicket *ticket,

                                                                GTLRDrive_FileList *fileList,

                                                                NSError *error) {

        if (!error)

        {

            NSLog(@"Drive search root folder results - %li", (unsigned long)fileList.files.count);

            

            NSString * newRootId = [fileList.files.firstObject identifier];

            

            if (newRootId.length > 0)

            {

                self.rootFolder = [fileList.files.firstObject folder];

                if (completionSearch)

                    completionSearch(YES, nil);

            }

            else

            {

                if (completionSearch)

                    completionSearch(NO, nil);

            }

        }

        else

        {

            if (completionSearch)

                completionSearch(NO, error);

            

            NSLog(@"DRIVE An error occurred: %@", error);

        }

    }];

}

There really isn't enough into to tell from the snippet you have.  I'd suggest turning on HTTP logging, and look at the generated log to try and see exactly what's going out and coming back.  If you are doing any custom configuration of `self.driveService` then it could be your specific values for the service's url that are wrong.

That URL isn't right.  How is your GTLRDriveService being configured, it would appear that you are overriding some of the configuration and that is what is causing the wrong urls to be created.

TVL

[Sergei Kvasov]

Thanks for your quick replies. You are right, GTLRDriveService configuration was wrong, now I use https://www.googleapis.com/drive/v3/ as rootURL and my fetch request works just fine! But I have another issue with file uploading, I'm trying to upload an image to Google Drive folder and I get an error with status 501, request log looks good:

You should have to set the url at all.  The default service should have the correct root url and servicePath.  There's a few different urls that get assembled from the parts, so forcing the root url to that is going to cause other problems.  Is there a reason you aren't using the defaults done by the generator?

[Sergei Kvasov]

Yes, I get exception if I don't specify root url: rootURLString should end in a slash: (null)

Again, how are you configuring the GTLRDriveService?  The generated code already has the correct values and this wouldn't happen: https://github.com/google/google-api-objectivec-client-for-rest/blob/master/Source/GeneratedServices/Drive/GTLRDriveService.m#L36-L41

[Sergei Kvasov]

Configuration that lead to exception:

-----------------------------------

- (GTLRService *)driveService

{

    static GTLRService *service = nil;

    

    if (!service)

    {

        service = [[GTLRService alloc] init];

        service.shouldFetchNextPages = NO;

        service.retryEnabled = YES;

    }

    if (!service.authorizer)

    {

        service.authorizer = self.client.authenticator.googleAuthorizer;

    }    

    

    return service;

}

-----------------------------------

and configuration that works fine(file upload/creation works too), diff in red:

-----------------------------------

- (GTLRService *)driveService

{

    static GTLRService *service = nil;

    

    if (!service)

    {

        service = [[GTLRService alloc] init];

        service.shouldFetchNextPages = NO;

        service.retryEnabled = YES;

        service.rootURLString = @"https://www.googleapis.com/";

        service.servicePath = @"drive/v3/";

        service.resumableUploadPath = @"resumable/upload/";

        service.simpleUploadPath = @"upload/";

        service.batchPath = @"batch/drive/v3";

        service.prettyPrintQueryParameterNames = @[ @"prettyPrint" ];

    }

    if (!service.authorizer)

    {

        service.authorizer = self.client.authenticator.googleAuthorizer;

    }    

    

    return service;

}

Why are you using GTLRService and not GTLRDriveService?  That's what is causing all of this.

TVL

[Sergei Kvasov]

Haha, yes, now I use GTLRDriveService and it works fine! It was not clear for me from the docs what class should I use. I should read docs more carefully. Thanks for help!
