上传Google云端存储iOS [英] Upload Google Cloud Storage iOS

问题描述

我正在尝试将图片上传到Google云端存储数天。
我尝试通过此链接使用适用于Objective-C的Google API客户端库 https://code.google.com/p/google-api-objectivec-client/wiki/Introduction 。

I'm trying to upload image to Google Cloud Storage for a couple days. I tried to use Google APIs Client Library for Objective-C from this link https://code.google.com/p/google-api-objectivec-client/wiki/Introduction.

这是我的代码实现：

_serviceStorage = [GTLServiceStorage new];
_serviceStorage.APIKey = API_KEY;
_serviceStorage.additionalHTTPHeaders = @{@"x-goog-project-id": PROJECT_ID};

GTLUploadParameters *uploadParam = [GTLUploadParameters uploadParametersWithData:_imageData MIMEType:@"image/jpeg"];
GTLStorageObject *storageObj = [GTLStorageObject object];

GTLQueryStorage *query = [GTLQueryStorage queryForObjectsInsertWithObject:storageObj bucket:BUCKET_NAME uploadParameters:uploadParam];
GTLServiceTicket *ticket = [_serviceStorage executeQuery:query delegate:self didFinishSelector:@selector(serviceTicket:finishedWithObject:error:)];

ticket.uploadProgressBlock = ^(GTLServiceTicket *ticket,
                               unsigned long long numberOfBytesRead,
                               unsigned long long dataLength) {
    self.progressView.progress = (float)numberOfBytesRead/(float)dataLength;
};

使用该代码，错误始终显示为操作无法完成。（未配置访问权限。请使用Google Developers Console激活项目的API）。我不知道为什么会出现错误，而我启用了与Google云端存储和Google云端存储JSON API等存储相关的所有服务，并更改了存储分区的ACL，以便互联网上的所有用户都可以写入/上传。

With that code, the error always appear "The operation couldn't be completed. (Access Not Configured. Please use Google Developers Console to activate the API for your project)". I don't know why error shows up whereas I've enabled all services related to storage like Google Cloud Storage and Google Cloud Storage JSON API and change ACL of the bucket so that all user on the internet can write/upload into it.

我还在上传之前尝试过身份验证过程。
viewDidLoad上的代码：

I also tried authentication process before upload. The code on viewDidLoad:

_serviceStorage = [GTLServiceStorage new];
_serviceStorage.additionalHTTPHeaders = @{@"x-goog-project-id": PROJECT_ID};
GTMOAuth2ViewControllerTouch *oAuthVC = [[GTMOAuth2ViewControllerTouch alloc] initWithScope:kScope
                                                                                   clientID:kClientID
                                                                               clientSecret:kClientSecret
                                                                           keychainItemName:kKeychainItemName
                                                                          completionHandler:^(GTMOAuth2ViewControllerTouch *viewController, GTMOAuth2Authentication *auth, NSError *error) {
                                                                              dispatch_async(dispatch_get_main_queue(), ^{
                                                                                  [self dismissViewControllerAnimated:YES completion:nil];
                                                                              });
                                                                              auth.authorizationTokenKey = @"access_token";
                                                                              _serviceStorage.authorizer = auth;
                                                                          }];

dispatch_async(dispatch_get_main_queue(), ^{
    [self presentViewController:oAuthVC animated:YES completion:nil];
});

当用户按上传按钮时：

GTLUploadParameters *uploadParam = [GTLUploadParameters uploadParametersWithData:_imageData MIMEType:@"image/jpeg"];
GTLStorageObject *storageObj = [GTLStorageObject object];

GTLQueryStorage *query = [GTLQueryStorage queryForObjectsInsertWithObject:storageObj bucket:BUCKET_NAME uploadParameters:uploadParam];
GTLServiceTicket *ticket = [_serviceStorage executeQuery:query delegate:self didFinishSelector:@selector(serviceTicket:finishedWithObject:error:)];

ticket.uploadProgressBlock = ^(GTLServiceTicket *ticket,
                               unsigned long long numberOfBytesRead,
                               unsigned long long dataLength) {
    self.progressView.progress = (float)numberOfBytesRead/(float)dataLength;
};

通过该实现，我得到了不同的错误，操作无法完成。（许可不足）。

With that implementation I got different error, "The operation couldn't be completed. (Insufficient Permission)".

我该怎么办才能成功上传图片？
任何帮助将不胜感激。

What should I do so that I can upload image successfully? Any help will be appreciated.

非常感谢。

推荐答案

最后我找到了答案。下面是用于认证的代码：

Finally I found the answer. Here is the code for authentication:

GTMOAuth2ViewControllerTouch *oAuthVC = [[GTMOAuth2ViewControllerTouch alloc] initWithScope:kGTLAuthScopeStorageDevstorageReadWrite
                                                                                       clientID:kClientID
                                                                                   clientSecret:kClientSecret
                                                                               keychainItemName:kKeychainItemName
                                                                              completionHandler:^(GTMOAuth2ViewControllerTouch *viewController, GTMOAuth2Authentication *auth, NSError *error) {

                                                                                  _accessToken = [NSString stringWithFormat:@"Bearer %@", [auth.parameters objectForKey:@"access_token"]];

                                                                                  _serviceStorage.additionalHTTPHeaders = @{@"x-goog-project-id": PROJECT_ID, @"Content-Type": @"application/json-rpc", @"Accept": @"application/json-rpc", @"Authorization": _accessToken};

                                                                                  _serviceStorage.authorizer = auth;


                                                                                  dispatch_async(dispatch_get_main_queue(), ^{
                                                                                      [self dismissViewControllerAnimated:YES completion:nil];
                                                                                  });
                                                                              }];

这里是上传过程：

GTLUploadParameters *uploadParam = [GTLUploadParameters uploadParametersWithData:_imageData MIMEType:@"image/jpeg"];
GTLStorageObject *storageObj = [GTLStorageObject object];
storageObj.name = FILE_NAME;

GTLQueryStorage *query = [GTLQueryStorage queryForObjectsInsertWithObject:storageObj bucket:BUCKET_NAME uploadParameters:uploadParam];
GTLServiceTicket *ticket = [_serviceStorage executeQuery:query completionHandler:^(GTLServiceTicket *ticket, id object, NSError *error) {
}];

ticket.uploadProgressBlock = ^(GTLServiceTicket *ticket,
                               unsigned long long numberOfBytesRead,
                               unsigned long long dataLength) {
    self.progressView.progress = (float)numberOfBytesRead/(float)dataLength;
};

或者如果您想在没有身份验证的情况下上传，您必须为键分配API密钥服务器应用程序不 iOS应用程序密钥

Or if you want to upload without authentication, you have to assign API Key with Key for server applications not Key for iOS applications

_serviceStorage.APIKey = KEY_SERVER_APPLICATION;

我不知道为什么上传过程成功使用密钥用于服务器应用程序而这是iOS应用程序

I don't know why the uploading process successful when using Key for server applications whereas this is an iOS Application
