我注册了谷歌API控制台的应用程序.我得到了我的客户端密码,客户端ID和两个重定向uris.
//● urn:xxxxxxx:oob
//● http://localhostxxxxxx
当然,我使用这些项目并成功请求令牌谷歌.但是当我点击授权按钮时(比如“你想授权这个应用程序吗?”是的),
两个响应发生.
如果我使用urnxxxxxx,我会收到“操作无法完成.(com.google.HTTPStatus错误404.)”.
//Or If I use http://localhostxxxxxxxxxxxxx and click Yes button, then nothing
happens.
我该怎么办? (以下代码适用于谷歌阅读器.)
#import "MasterViewController.h"
#import "DetailViewController.h"
#import "GTMOAuth2Authentication.h"
#import "GTMOAuth2ViewControllerTouch.h"
#import "GTMOAuth2WindowController.h"
static NSString *const kKeychainItemName = @"Greader";
@interface MasterViewController () {
NSMutableArray *_objects;
}
@end
@implementation MasterViewController
- (IBAction)authentication:signInToGoogle:(id)sender;
{}
- (GTMOAuth2Authentication * ) authForGoogle
{
NSString * url_string = @"http://www.google.com/reader/api/";
NSURL * tokenURL = [NSURL URLWithString:url_string];
NSString * redirectURI = @"xxxxoob";
GTMOAuth2Authentication * auth;
auth = [GTMOAuth2Authentication authenticationWithServiceProvider:@"reader"
tokenURL:tokenURL
redirectURI:redirectURI
clientID:@"xxxxx"
clientSecret:@"xxxx"];
auth.scope = @"http://www.google.com/reader/api/";
return auth;
}
- (void)signInToGoogle
{
GTMOAuth2Authentication * auth = [self authForGoogle];
NSString* auth_string = @"https://accounts.google.com/o/oauth2/auth";
NSURL * authURL = [NSURL URLWithString:auth_string];
GTMOAuth2ViewControllerTouch * viewController;
viewController = [[GTMOAuth2ViewControllerTouch alloc]initWithAuthentication:auth
authorizationURL:authURL
keychainItemName:kKeychainItemName
delegate:self
finishedSelector:@selector(viewController:finishedWithAuth:error:)];
[self.navigationController pushViewController:viewController animated:YES];
}
最佳答案 你应该先了解oAuth.
通常,第一个链接是授权流程 – 您调用它并获取代码.
第二个URL是使用您从上一个URL获得的代码获取令牌.
解释如何与oAuth合作完全超出了范围,但是您可以阅读和学习很多地方.
