Question

Google Drive API支持人员，

过去几天，我们遇到了Google云端硬盘的严重问题。

我们无法再使用图片更新文档文档。当我们的iPhone应用程序发送更新包含图像的Docs文档的请求时，服务器返回OK，但内部图像将永远不会上传。

此处重现问题的代码。

- (void)selfOverwriteSelectedFile:(GTLDriveFile *)gtlDriveFile
{
    // -- not working type -- can't upload images on ODT, HTML, RTF, PDF
    NSString *mimetype = @"application/vnd.oasis.opendocument.text"; //@"text/html" @"application/rtf" @"application/pdf"

    //works: DOCX
    //NSString *mimetype = @"application/vnd.openxmlformats-officedocument.wordprocessingml.document";

    NSString *downloadUrl = [gtlDriveFile.exportLinks additionalPropertyForName:mimetype];

    //1st request: download the file
    GTMHTTPFetcher *fetcher = [self.driveService.fetcherService fetcherWithURLString:downloadUrl];

    [fetcher beginFetchWithCompletionHandler:^(NSData *data, NSError *error) {
        //2nd request: re-upload the same file
        gtlDriveFile.mimeType = mimetype;
        GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithData:data MIMEType:mimetype];
        GTLQueryDrive *query = [GTLQueryDrive queryForFilesUpdateWithObject:gtlDriveFile fileId:gtlDriveFile.identifier uploadParameters:uploadParameters];
        query.convert = query.newRevision = query.setModifiedDate = YES;

        [self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLDriveFile *newGtlFile, NSError *error2nd) {
        }];
    }];
}

//replace the method for easy-test
-(void)duplicateSelectedFile
{
    GTLDriveFile *selectedFile = [self selectedFileListEntry];
    [self selfOverwriteSelectedFile:selectedFile];
}

为了最简单的复制，

下载最新的“用于Objective-C的Google API客户端库”。
在XCode中打开DriveSample项目。
将“ - （void）duplicateSelectedFile”方法替换为代码。
编译并执行修改后的示例应用程序“获取文件列表”，选择带有图像的文档文件，然后点击“复制”。
应使用相同的内容覆盖所选文件。但是，里面的图像都丢失了（在无休止的等待上传状态下）。

仅供参考，odt / html / rtf / pdf导入不起作用。但是，docx导入有效。

请尽快解决问题。

感谢您的支持。
