如何在谷歌驱动器上传图像（错误“GTMHTTPUploadFetcher connectionDidFinishLoading中的断言失败”）

Question

我正在尝试在我的iOS应用中使用Google云端硬盘。我尝试上传文件，我收到以下错误：

*** Assertion failure in -[GTMHTTPUploadFetcher connectionDidFinishLoading:], 

/Users/mac/Desktop/google-api-objectivec-client-mirror-master/Source/HTTPFetcher/GTMHTTPUploadFetcher.m:399

以下是断言发生时突出显示的代码：

NSAssert([[self downloadedData] length] == 0,
                @"unexpected response data (uploading to the wrong URL?)");

将图片上传到Google云端硬盘：

- (void)uploadPhoto
{
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"'Quickstart Uploaded File ('EEEE MMMM d, YYYY h:mm a, zzz')"];
GTLDriveFile *file = [GTLDriveFile object];
file.title = [dateFormat stringFromDate:[NSDate date]];
file.descriptionProperty = @"Uploaded from the Google Drive iOS Quickstart";
file.mimeType = @"image/png";

UIImage   *img =[UIImage imageNamed:@"Default.png"];
NSData *data = UIImagePNGRepresentation(img);

GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithData:data MIMEType:file.mimeType];
GTLQueryDrive *query = [GTLQueryDrive queryForFilesInsertWithObject:file
                                                   uploadParameters:uploadParameters];
UIAlertView *waitIndicator = [self showWaitIndicator:@"Uploading to Google Drive"];

[self.driveService executeQuery:query
              completionHandler:^(GTLServiceTicket *ticket,GTLDriveFile *insertedFile, NSError *error)
 {
     [waitIndicator dismissWithClickedButtonIndex:0 animated:YES];
     if (error == nil)
     {
         NSLog(@"File ID: %@", insertedFile.identifier);
         [self showAlert:@"Google Drive" message:@"File saved!"];
     }
     else
     {
         NSLog(@"An error occurred: %@", error);
         [self showAlert:@"Google Drive" message:@"Sorry, an error occurred!"];
     }
 }];
  }

Answer 1

试试这个，

我在GTMHTTPUploadFetcher connectionDidFinishLoading“）中纠正了断言失败，但遗憾的是我忘了启用Google API Console Drive API

1.创建一个应用程序。

2.转到“服务”，打开“Drive API”。

您需要从API控制台/服务标签

启用Drive API和Drive SDK
