GTMSessionfetcher谷歌驱动器上传到谷歌驱动目标-C？

Question

根据这里发布的文档，我可以用GTMSessionFetcher下载和上传。在文档格式的链接中，我有一个授权下载的代码，google：

GTLRQuery *query = [GTLRDriveQuery_FilesGet queryForMediaWithFileId:fileID];
NSURLRequest *downloadRequest = [service requestForQuery:query];
GTMSessionFetcher *fetcher =
  [service.fetcherService fetcherWithRequest:downloadRequest];

[fetcher beginFetchWithCompletionHandler:^(NSData *data, NSError *fetchError) {
  if (fetchError == nil) {
    // Download succeeded.
  }
}];

很好用！

我的问题是:如何与GTMSessionFetcher一起上传到iOS中的Google？

Answer 1

尝试使用会话Fetcher中的代码

@interface GTMSessionUploadFetcher : GTMSessionFetcher

// Create an upload fetcher specifying either the request or the resume location URL,
// then set an upload data source using one of these:
//
//   setUploadFileURL:
//   setUploadDataLength:provider:
//   setUploadFileHandle:
//   setUploadData:

+ (instancetype)uploadFetcherWithRequest:(NSURLRequest *)request
                          uploadMIMEType:(NSString *)uploadMIMEType
                               chunkSize:(int64_t)chunkSize
                          fetcherService:(GTM_NULLABLE GTMSessionFetcherService *)fetcherServiceOrNil;

+ (instancetype)uploadFetcherWithLocation:(NSURL * GTM_NULLABLE_TYPE)uploadLocationURL
                           uploadMIMEType:(NSString *)uploadMIMEType
                                chunkSize:(int64_t)chunkSize
                           fetcherService:(GTM_NULLABLE GTMSessionFetcherService *)fetcherServiceOrNil;

- (void)setUploadDataLength:(int64_t)fullLength
                   provider:(GTM_NULLABLE GTMSessionUploadFetcherDataProvider)block;

github代码指出，GTMSessionFetcher使Cocoa应用程序更容易执行http操作。该取款器是在NSURLSession，上作为包装器实现的，因此它的行为是异步的，并且在iOS和Mac上使用操作系统设置。

希望这能有所帮助。
