我找到了Google提供的服务,可以访问各种Google服务的Google Api.我可以在iPhone中设置一个项目,并为iOS应用程序(通过OAuth2.0)和本机应用程序创建API访问.我想为我的iPhone应用程序使用本机API.它API为我提供了电子邮件,全名,名字,姓氏,google_id,性别,dob,profile_image.如何在我的iPhone应用程序,任何示例应用程序,可用的代码段中使用这些？
请帮我.
这是我的代码：
-(void) loadGmail_Login
{
Nsstring *keychainItemName = nil;
if ([self shouldSaveInKeychain]) {
keychainItemName = kKeychainItemName;
}
// For GTM applications,the scope is available as
Nsstring *scope = @"http://www.google.com/m8/Feeds/";
// ### Important ###
// GTMOAuthViewControllerTouch is not designed to be reused. Make a new
// one each time you are going to show it.
// display the autentication view.
GTMOAuthAuthentication *auth;
auth = [GTMOAuthViewControllerTouch authForGoogleFromKeychainForName:kKeychainItemName];
GTMOAuthViewControllerTouch *viewController = [[[GTMOAuthViewControllerTouch alloc]
initWithScope:scope
language:nil
appServiceName:keychainItemName
delegate:self
finishedSelector:@selector(viewController:finishedWithAuth:error:)] autorelease];
// You can set the title of the navigationItem of the controller here,if you want.
// 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 setinitialHTMLString:html];
[[self navigationController] pushViewController:viewController animated:YES];
}
- (void)viewController:(GTMOAuthViewControllerTouch *)viewController
finishedWithAuth:(GTMOAuthAuthentication *)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);
}
[self setAuthentication:nil];
}
else
{
// save the authentication object
[self setAuthentication:auth];
// Just to prove we're signed in,we'll attempt an authenticated fetch for the
// signed-in user
[self doAnAuthenticatedAPIFetch];
}
}
- (void)doAnAuthenticatedAPIFetch
{
Nsstring *urlStr;
// Google Contacts Feed
//
// https://www.googleapis.com/oauth2/v2/userinfo
urlStr = @"http://www.google.com/m8/Feeds/contacts/default/thin";
NSURL *url = [NSURL URLWithString:urlStr];
NSMutableuRLRequest *request = [NSMutableuRLRequest requestWithURL:url];
[mAuth authorizeRequest:request];
NSError *error = nil;
NSURLResponse *response = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&error];
if (data) {
// API fetch succeeded
Nsstring *str = [[[Nsstring alloc] initWithData:data
encoding:NSUTF8StringEncoding] autorelease];
NSLog(@"API response: %@",str);
GGCXml_Adaptor *localAlphabetXMLParser = [[GGCXml_Adaptor alloc] init];
[localAlphabetXMLParser processBooksXML:data];
[localAlphabetXMLParser release];
// [self updateUI];
} else {
// fetch Failed
NSLog(@"API fetch error: %@",error);
}
}
- (void)setAuthentication:(GTMOAuthAuthentication *)auth {
[mAuth autorelease];
mAuth = [auth retain];
}
解决方法
首先,您需要从Google Api获取令牌,对于第一步,您必须遵循本教程,并在此链接的末尾有完整的iOS源代码,用于从Google Api获取令牌

然后在下一步中,您必须将该令牌发送到Google Api以请求用户数据,我只需要第一步所以我正在分享我的搜索
