我已经按照“非 Google 服务”的文档设置了 OAuth 请求，并且完成了 90% 的工作。该应用程序会显示一个 Web 视图，我可以在其中使用我的应用程序的正确访问令牌登录 Instagram 并接受范围请求，但一旦我接受请求，我会收到以下错误：
Error Error Domain=com.google.HTTPStatus Code=400 "The operation couldn’t be completed.

控制器似乎正在尝试针对 google.com 而不是 api.instagram.com 完成 OAuth 事务。
这是我用于设置和调用控制器的 Objective-C 代码：
static NSString *const kKeychainItemName = @"Instagram OAuth2";
static NSString *const kClientID = @"xxxxxxxxx"; // Removed for security
static NSString *const kClientSecret = @"xxxxxxxxx"; // Removed for security
static NSString *const authURLString = @"https://api.instagram.com/oauth/authorize/";
static NSString *const tokenURLString = @"https://api.instagram.com/oauth/authorize/";
static NSString *const redirectURI = @"http://google.com/NeverGonnaFindMe/";
...
NSURL *tokenURL = [NSURL URLWithString:tokenURLString];
// Set up the OAuth request
GTMOAuth2Authentication *auth = [GTMOAuth2Authentication
authenticationWithServiceProvider:@"Instagram API"
tokenURL:tokenURL
redirectURI:redirectURI
clientID:kClientID
clientSecret:kClientSecret
];
// Specify the appropriate scope string, if any, according to the service's API documentation
auth.scope = @"basic likes comments relationships";
NSURL *authURL = [NSURL URLWithString:authURLString];
// Display the authentication view
GTMOAuth2ViewControllerTouch *viewController = [[GTMOAuth2ViewControllerTouch alloc]
initWithAuthentication:auth
authorizationURL:authURL
keychainItemName:kKeychainItemName
delegate:self
finishedSelector:@selector(viewController:finishedWithAuth:error:)
];
// Capture the Cookie to delete later
viewController.browserCookiesURL = [NSURL URLWithString:@"instagram.com/"];
// Now push our sign-in view
[[self navigationController] pushViewController:viewController animated:YES];
