【问题描述】：

我正在使用 GTMOAuth2 库登录过程进行 g 邮件身份验证，但重定向时间出错

 #define GoogleAuthURL   @"https://accounts.google.com/o/oauth2/auth"
    #define GoogleTokenURL  @"https://accounts.google.com/o/oauth2/token"

    NSURL * tokenURL = [NSURL URLWithString:GoogleTokenURL];

        NSString * redirectURI = @"";

        GTMOAuth2Authentication * auth;

        auth = [GTMOAuth2Authentication authenticationWithServiceProvider:@"google"
                                                                 tokenURL:tokenURL

        [self.navigationController pushViewController:viewcontroller animated:YES];




 Error Domain=com.google.GTMOAuth2 Code=-1001 "The operation couldn’t be completed. (com.google.GTMOAuth2 error -1001.)"

请帮帮我

试试这个

【讨论】：

兄弟，我导入了那些类相同的代码，但仍然发生错误

***.com/questions/16828135/…看看这个步骤

【参考方案2】：

试试下面的代码....可能会对你有所帮助我的朋友...先在 ViewDidLoad 中编写下面的代码。

- (void)viewDidLoad

 NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

NSString *clientID = [defaults stringForKey:kGoogleClientIDKey];
NSString *clientSecret = [defaults stringForKey:kGoogleClientSecretKey];

GTMOAuth2Authentication *auth = nil;

if (clientID && clientSecret) 
    auth = [GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:kKeychainItemName
                                                                 clientID:clientID
                                                             clientSecret:clientSecret];





// Save the authentication object, which holds the auth tokens and
// the scope string used to obtain the token.  For Google services,
// the auth object also holds the user's email address.
self.auth = auth;

// Update the client ID value text fields to match the radio button selection
[self loadClientIDValues];


 - (void)loadClientIDValues 
// Load the client ID and secret from the prefs into the text fields
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
mClientIDField.text = [defaults stringForKey:kGoogleClientIDKey];
mClientSecretField.text = [defaults stringForKey:kGoogleClientSecretKey];

然后在 gmail 的登录操作上写下面的代码...

-(IBAction)gmailLogin

[self saveClientIDValues];//this is the method for saving the credentials of gmail account of particular user.

if (![self isSignedIn]) 
    // Sign in
    [self signInToGoogle];

 else 
    // Sign out
    [self signOut];




- (void)saveClientIDValues 
// Save the client ID and secret from the text fields into the prefs
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *clientID = mClientIDField.text;
NSString *clientSecret = mClientSecretField.text;

[defaults setObject:clientID forKey:kGoogleClientIDKey];
[defaults setObject:clientSecret forKey:kGoogleClientSecretKey];

检查用户是否登录！！！

- (BOOL)isSignedIn 
BOOL isSignedIn = self.auth.canAuthorize;
return isSignedIn;

如果用户未登录，则进行登录...

 - (void)signInToGoogle 
[self signOut];
NSString *keychainItemName = nil;
keychainItemName = kKeychainItemName;

// For Google APIs, the scope strings are available
// in the service constant header files.
NSString *scope = @"https://www.googleapis.com/auth/plus.me";

// Typically, applications will hardcode the client ID and client secret
// strings into the source code; they should not be user-editable or visible.
//
// But for this sample code, they are editable.
NSString *clientID = @"Your Id";
NSString *clientSecret = @"Your Secret";

if ([clientID length] == 0 || [clientSecret length] == 0) 
 //   NSString *msg = @"The sample code requires a valid client ID and client secret to sign in.";
    return;


// Note:
// GTMOAuth2ViewControllerTouch is not designed to be reused. Make a new
// one each time you are going to show it.

// Display the autentication view.
SEL finishedSel = @selector(viewController:finishedWithAuth:error:);

GTMOAuth2ViewControllerTouch *viewController;
viewController = [GTMOAuth2ViewControllerTouch controllerWithScope:scope
                                                          clientID:clientID
                                                      clientSecret:clientSecret
                                                  keychainItemName:keychainItemName
                                                          delegate:self
                                                  finishedSelector:finishedSel];

NSDictionary *params = [NSDictionary dictionaryWithObject:@"en"
                                                   forKey:@"hl"];
viewController.signIn.additionalAuthorizationParameters = params;

// By default, the controller will fetch the user's email, but not the rest of
// the user's profile.  The full profile can be requested from Google's server
// by setting this property before sign-in:
//
viewController.signIn.shouldFetchGoogleUserProfile = YES;
//
// The profile will be available after sign-in as
//
// NSDictionary *profile = viewController.signIn.userProfile;
NSDictionary *profile = viewController.signIn.userProfile;
NSLog(@"%@",profile);
// Optional: display some html briefly before the sign-in page loads
NSString *html = @"<html><body bgcolor=silver><div align=center>Loading sign-in page...</div></body></html>";
viewController.initialHTMLString = html;

[[self navigationController] pushViewController:viewController animated:YES];

// The view controller will be popped before signing in has completed, as
// there are some additional fetches done by the sign-in controller.
// The kGTMOAuth2UserSignedIn notification will be posted to indicate
// that the view has been popped and those additional fetches have begun.
// It may be useful to display a temporary UI when kGTMOAuth2UserSignedIn is
// posted, just until the finished selector is invoked.
 

如果一切都正确，那么您将在以下方法中得到结果...

- (void)viewController:(GTMOAuth2ViewControllerTouch *)viewController
  finishedWithAuth:(GTMOAuth2Authentication *)auth
             error:(NSError *)error 
  if (error != nil) 
    // Authentication failed (perhaps the user denied access, or closed the
    // window before granting access)
    NSLog(@"Authentication error: %@", error);
    NSData *responseData = [[error userInfo] objectForKey:@"data"]; // kGTMHTTPFetcherStatusDataKey
    if ([responseData length] > 0) 
        // show the body of the server's authentication failure response
        NSString *str = [[[NSString alloc] initWithData:responseData
                                               encoding:NSUTF8StringEncoding] autorelease];
        NSLog(@"%@", str);
    
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Eye News" message:@"Gmail Authentication Fail. Please try again" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
    [alert release];

    self.auth = nil;
 
else

  viewController.signIn.shouldFetchGoogleUserProfile = YES;
    NSDictionary *profile = viewController.signIn.userProfile;
    NSLog(@"%@",profile);
 

让我知道它是否有效！！！！

编码愉快！！！！

【讨论】：

controllerWithScope：此方法不在 GTMOAuth2ViewControllerTouch 类中

你有这些名为 GTMOAuth2ViewControllerTouch.h 和 GTMOAuth2ViewControllerTouch.m 的类文件吗？？？？
