在我的项目中想要有这样的流程：
用户录制短视频 - ＆gt;他们在我的频道上传视频 - ＆gt;端
要实现此结果，我正在尝试使用适用于REST的Objective-C的新Google API客户端库。它的文档很差，示例仅适用于mac。无论如何，经过多次错误，这是我的代码：
- (void)doAuthWithoutCodeExchange:(OIDServiceConfiguration *)configuration
clientID:(NSString *)clientID
clientSecret:(NSString *)clientSecret {
NSURL *redirectURI = [NSURL URLWithString:kRedirectURI];
// builds authentication request
OIDAuthorizationRequest *request =
[[OIDAuthorizationRequest alloc] initWithConfiguration:configuration
clientId:clientID
clientSecret:clientSecret
scopes:@[ OIDScopeOpenID, OIDScopeProfile ]
redirectURL:redirectURI
responseType:OIDResponseTypeCode
additionalParameters:nil];
// performs authentication request
AppDelegate *appDelegate = (AppDelegate *) [UIApplication sharedApplication].delegate;
[self logMessage:@"Initiating authorization request %@", request];
appDelegate.currentAuthorizationFlow =
[OIDAuthorizationService presentAuthorizationRequest:request
presentingViewController:self
callback:^(OIDAuthorizationResponse *_Nullable authorizationResponse,
NSError *_Nullable error) {
if (authorizationResponse) {
OIDAuthState *authState =
[[OIDAuthState alloc] initWithAuthorizationResponse:authorizationResponse];
[self setAuthState:authState];
[self logMessage:@"Authorization response with code: %@",
authorizationResponse.authorizationCode];
// could just call [self tokenExchange:nil] directly, but will let the user initiate it.
OIDTokenRequest *tokenExchangeRequest =
[_authState.lastAuthorizationResponse tokenExchangeRequest];
[self logMessage:@"Performing authorization code exchange with request [%@]",
tokenExchangeRequest];
[OIDAuthorizationService performTokenRequest:tokenExchangeRequest
callback:^(OIDTokenResponse *_Nullable tokenResponse,
NSError *_Nullable error) {
if (!tokenResponse) {
[self logMessage:@"Token exchange error: %@", [error localizedDescription]];
} else {
[self logMessage:@"Received token response with accessToken: %@", tokenResponse.accessToken];
}
[_authState updateWithTokenResponse:tokenResponse error:error];
GTMAppAuthFetcherAuthorization *gtmAuthorization =
[[GTMAppAuthFetcherAuthorization alloc] initWithAuthState:authState];
// Sets the authorizer on the GTLRYouTubeService object so API calls will be authenticated.
self.youTubeService.authorizer = gtmAuthorization;
// Serializes authorization to keychain in GTMAppAuth format.
[GTMAppAuthFetcherAuthorization saveAuthorization:gtmAuthorization
toKeychainForName:kGTMAppAuthKeychainItemName];
[self uploadVideoFile];
}];
} else {
[self logMessage:@"Authorization error: %@", [error localizedDescription]];
}
}];
}
此方法导致此流程：
app将用户发送到safari中的google登录页面 - ＆gt;用户使用他的凭据登录 - ＆gt;登录后，用户将重定向回我的应用程序 - ＆gt;块成功调用方法UploadVideo。
这部分流程似乎工作正常，我获得了一个有效的令牌，如日志所示。第二部分是视频上传，包含两个主要方法：
- (void)uploadVideoFile {
// Collect the metadata for the upload from the user interface.
// Status.
GTLRYouTube_VideoStatus *status = [GTLRYouTube_VideoStatus object];
status.privacyStatus = @"public";
// Snippet.
GTLRYouTube_VideoSnippet *snippet = [GTLRYouTube_VideoSnippet object];
snippet.title = @"title";
NSString *desc = @"description";
if (desc.length > 0) {
snippet.descriptionProperty = desc;
}
NSString *tagsStr = @"tags";
if (tagsStr.length > 0) {
snippet.tags = [tagsStr componentsSeparatedByString:@","];
}
GTLRYouTube_Video *video = [GTLRYouTube_Video object];
video.status = status;
video.snippet = snippet;
[self uploadVideoWithVideoObject:video
resumeUploadLocationURL:nil];
}
- (void)uploadVideoWithVideoObject:(GTLRYouTube_Video *)video
resumeUploadLocationURL:(NSURL *)locationURL {
NSURL *fileToUploadURL = [NSURL fileURLWithPath:self.VideoUrlCri.path];
NSError *fileError;
NSLog(@"step");
if (![fileToUploadURL checkPromisedItemIsReachableAndReturnError:&fileError]) {
NSLog(@"exit");
return;
}
// Get a file handle for the upload data.
NSString *filename = [fileToUploadURL lastPathComponent];
NSString *mimeType = [self MIMETypeForFilename:filename
defaultMIMEType:@"video/mp4"];
GTLRUploadParameters *uploadParameters =
[GTLRUploadParameters uploadParametersWithFileURL:fileToUploadURL
MIMEType:mimeType];
uploadParameters.uploadLocationURL = locationURL;
GTLRYouTubeQuery_VideosInsert *query =
[GTLRYouTubeQuery_VideosInsert queryWithObject:video
part:@"snippet,status"
uploadParameters:uploadParameters];
query.executionParameters.uploadProgressBlock = ^(GTLRServiceTicket *ticket,
unsigned long long numberOfBytesRead,
unsigned long long dataLength) {
NSLog(@"upload progress");
};
GTLRYouTubeService *service = self.youTubeService;
_uploadFileTicket = [service executeQuery:query
completionHandler:^(GTLRServiceTicket *callbackTicket,
GTLRYouTube_Video *uploadedVideo,
NSError *callbackError) {
if (callbackError == nil) {
NSLog(@"uploaded");
} else {
NSLog(@"error %@",callbackError);
}
}];
}
- (NSString *)MIMETypeForFilename:(NSString *)filename
defaultMIMEType:(NSString *)defaultType {
NSString *result = defaultType;
NSString *extension = [filename pathExtension];
CFStringRef uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension,
(__bridge CFStringRef)extension, NULL);
if (uti) {
CFStringRef cfMIMEType = UTTypeCopyPreferredTagWithClass(uti, kUTTagClassMIMEType);
if (cfMIMEType) {
result = CFBridgingRelease(cfMIMEType);
}
CFRelease(uti);
}
return result;
}
我在NSLog(@"error %@",callbackError);中收到403错误，我看不到错误详情，因为它类似于：
data=<7b226572 726f7222 3a7b2265 72726f72 73223a5b 7b22646f 6d61696e 223a2267 6c6f6261 6c222c22 72656173 6f6e223a 22696e73 75666669 ... 61676522 3a22496e 73756666 69636965 6e742050 65726d69 7373696f 6e227d7d>}
在google api控制台中，我为我的应用程序包和API密钥创建了一个Client Oauth，我将这些值用于我的连接，看起来它们正常工作，因为我获得了一个有效的令牌。无论如何，有人可以帮助我或指出我正确的方向这个错误？或者有人知道有关IOS视频上传的工作示例而不是MAC？我的代码有些奇怪吗？我在文档或谷歌中找不到任何帮助
