Google Drive API IOS Permissions of GTLRDriveService

Question

我正在使用Google Drive API播放，并尝试构建一个将图片上传到我的Google Drive的简单应用程序。一旦用户登录，该应用程序应该上传图片，但是它给出了

的错误

" 2017-09-14 00：55：20.342237-0400 drivetest [6705：1647551]错误 发生：错误域= com.google.gtlrrorrobjectDomain代码= 403 "许可不足" userInfo = {gtlrStructuredRor = gtlrerrorobject 0x1C4251D30： {消息："权限不足"错误：[1]代码：403}，， nslocalizedDescription =不足许可}"

我试图将其传递给gtlrdriveservice类型的服务到USERETUP类的INITSETUP（）函数，但无济于事。有人可以将我指向正确的轨道，即使我正确登录了为什么我的权限不起作用，而我在GTLRDRDRIVESERVICE中传递的部分是在成功登录后运行的代码中。

。

我实例化了一个用户表对象，我令setupuser = userEtup（）setupuser.initsetup（service）

我的userSetup编写了目标c，并且可以正确桥接它，因为我能够在用swift编写的viewController文件中实例化。

usersetup ::::::::

#import "userSetUp.h"
#import <GoogleSignIn/GoogleSignIn.h>
@import GoogleAPIClientForREST;

@implementation userSetUp
- (void) initSetup:(GTLRDriveService *) driveService {

    printf("heloooooaiosuoiadoidauoalo");
    //GTLRDriveService *driveService = [GTLRDriveService new];
    //NSData *fileData = [[NSFileManager defaultManager] contentsAtPath:@"files/apple.jpg"];
    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"apple" ofType:@"jpg"];
    NSData *fileData = [NSData dataWithContentsOfFile:filePath];
    GTLRDrive_File *metadata = [GTLRDrive_File object];
    metadata.name = @"apple.jpg";
    //metadata.mimeType = @"application/vnd.google-apps.document";
    GTLRUploadParameters *uploadParameters = [GTLRUploadParameters uploadParametersWithData:fileData
                                                                                   MIMEType:@"image/jpeg"];
    uploadParameters.shouldUploadWithSingleRequest = TRUE;
    GTLRDriveQuery_FilesCreate *query = [GTLRDriveQuery_FilesCreate queryWithObject:metadata
                                                                   uploadParameters:uploadParameters];
    query.fields = @"id";
    [driveService executeQuery:query completionHandler:^(GTLRServiceTicket *ticket,
                                                         GTLRDrive_File *file,
                                                         NSError *error) {
        if (error == nil) {
            //NSLog(@"File ID %@", file.identifier);
            printf("it worked");
        } else {
            NSLog(@"An error occurred: %@", error);
        }
    }];

printf("upload complete!");

尝试更改范围：

class ViewController: UIViewController, GIDSignInDelegate, GIDSignInUIDelegate
{
    // If modifying these scopes, delete your previously saved credentials by
    private let scopes = ["https://www.googleapis.com/auth/drive"]
    ...
}
