Question

我尝试使用Google通讯录APi获取所有谷歌联系人，但我没有找到适用于iOS的任何内容。 OAuth无效，因为Google更改了使用WebView OAuth的政策。我使用Google登录框架获取访问令牌，但此令牌对谷歌联系人API无效： https://www.google.com/m8/feeds/contacts/default/full

请建议使用最新的iOS SDK 10+和最新的google框架来获取google / gmail联系人

Answer 1

尝试使用适用于iOS的GIDSignIn Class来解决您的OAuth问题。

请参阅"Google Sign-In for iOS"以下是使用GIDSignIn的示例代码：

获取对GIDSignIn共享实例的引用：GIDSignIn * signIn = [GIDSignIn sharedInstance];
设置您要请求的OAuth 2.0范围：[signIn setScopes：[NSArray arrayWithObject：@＆＃34; https://www.googleapis.com/auth/plus.login＆＃34;]];
致电[signIn setDelegate：self];
设置委托方法signIn：didSignInForUser：withError：。
在应用程序中调用共享实例上的handleURL：openUrl：...在您的app delegate中。
在共享实例上调用signIn;

I）尝试GIDSignIn Class进行身份验证：

II）导入所需的类作为休假：

#import <UIKit/UIKit.h>
#import <GoogleSignIn/GoogleSignIn.h>    
@interface ViewController : UIViewController<GIDSignInDelegate,GIDSignInUIDelegate,NSURLSessionDelegate>

@end

III）在viewDidLoad中充当休假：

- (void)viewDidLoad {
    [super viewDidLoad];

    [GIDSignIn sharedInstance].delegate = self;
    [GIDSignIn sharedInstance].uiDelegate = self;
    [GIDSignIn sharedInstance].clientID = "your_CLIENT_ID; //get from console
    [[GIDSignIn sharedInstance] setScopes:@[@"https://www.googleapis.com/auth/plus.login",@"https://www.googleapis.com/auth/plus.me",@"https://www.googleapis.com/auth/contacts",@"https://www.googleapis.com/auth/contacts.readonly"]];

    // Button for opening Google Auth //

    GIDSignInButton *button = [[GIDSignInButton alloc]initWithFrame:CGRectMake(0.0f, 0.0f, 200.0f, 200.0f)];
    button.style = kGIDSignInButtonStyleWide;
    button.colorScheme  =kGIDSignInButtonColorSchemeLight;
    [button setCenter:self.view.center];
    [self.view addSubview:button];
}

IV）用户完成登录后，请按GIDSignInUIDelegate进行如下操作：

- (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user withError:(NSError *)error {

    // Perform any operations on signed in user here.
    NSString *userId = user.userID;                  // For client-side use only!
    NSString *idToken = user.authentication.idToken; // Safe to send to the server
    NSString *fullName = user.profile.name;
    NSString *givenName = user.profile.givenName;
    NSString *familyName = user.profile.familyName;
    NSString *email = user.profile.email;

    [self getPeopleList];
    // ...
}
// Implement these methods only if the GIDSignInUIDelegate is not a subclass of
// UIViewController.

// Stop the UIActivityIndicatorView animation that was started when the user
// pressed the Sign In button
- (void)signInWillDispatch:(GIDSignIn *)signIn error:(NSError *)error {
    NSLog(@"0.0.");

}

// Present a view that prompts the user to sign in with Google
- (void)signIn:(GIDSignIn *)signIn presentViewController:(UIViewController *)viewController {
    [self presentViewController:viewController animated:YES completion:nil];
}

// Dismiss the "Sign in with Google" view
- (void)signIn:(GIDSignIn *)signIn dismissViewController:(UIViewController *)viewController {
    [self dismissViewControllerAnimated:YES completion:nil];
}

V）现在在-(void)getPeopleList{}中，您将找到联系人：

-(void)getPeopleList{

    NSString *url = [NSString stringWithFormat:@"https://people.googleapis.com/v1/people/me/connections?personFields=emailAddresses"];

    NSURL *linkurl = [NSURL URLWithString:url];


    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:linkurl
                                                           cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                       timeoutInterval:60.0];

    [request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request addValue:[NSString stringWithFormat:@"Bearer %@",[GIDSignIn sharedInstance].currentUser.authentication.accessToken] forHTTPHeaderField:@"Authorization"];
    [request setHTTPMethod:@"GET"];

    NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

        if (!error) {
            NSDictionary *user_contact_json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
            NSLog(@"user_contacts %@", user_contact_json);
        } else {
            NSLog(@"Error %@",error);
        }
    }];

    [postDataTask resume];

}
