Iphone Tripit+；GTMOAUTHVIEW控制器触摸屏

我有一个iPhone应用程序。我正在尝试使用GTMOAuthViewControllerTouch添加tripit支持。它使用4个NSURL：

NSString *myConsumerKey = kTripItAPIKey;        // pre-registered with service
NSString *myConsumerSecret = kTripItAPISecret;  // pre-assigned by service

GTMOAuthAuthentication *auth = [[[GTMOAuthAuthentication alloc] initWithSignatureMethod:kGTMOAuthSignatureMethodHMAC_SHA1
                                                                            consumerKey:myConsumerKey
                                                                             privateKey:myConsumerSecret] autorelease];

// setting the service name lets us inspect the auth object later to know
// what service it is for
auth.serviceProvider = @"Tripit";

NSURL *requestURL = [NSURL URLWithString:@"https://api.tripit.com/oauth/request_token"];
NSURL *accessURL = [NSURL URLWithString:@"https://api.tripit.com/oauth/access_token"];
NSURL *authorizeURL = [NSURL URLWithString:@"https://m.tripit.com/oauth/authorize"];
NSString *scope = @"https://api.tripit.com/scope";

GTMOAuthAuthentication *auth = [self myCustomAuth];

// set the callback URL to which the site should redirect, and for which
// the OAuth controller should look to determine when sign-in has
// finished or been canceled
//
// This URL does not need to be for an actual web page
[auth setCallback:@"https://api.tripit.com/OAuthCallback"];

// Display the autentication view
GTMOAuthViewControllerTouch *viewController = [[[GTMOAuthViewControllerTouch alloc] initWithScope:scope
                                                                                         language:nil
                                                                                  requestTokenURL:requestURL
                                                                                authorizeTokenURL:authorizeURL
                                                                                   accessTokenURL:accessURL
                                                                                   authentication:auth
                                                                                   appServiceName:@"AppName"
                                                                                         delegate:self
                                                                                 finishedSelector:@selector(viewController:finishedWithAuth:error:)] autorelease];

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

我正在阅读官方文档，发现了请求、访问和授权URL，但它没有提到“范围”和OAuthCallbackURL？。当我尝试访问时，我从Tripit网站收到“访问请求失败”的消息。怎么了-（

我会回答这个问题，以防其他人遇到同样的问题

您需要稍微修改Google的项目以将其与TripIt一起使用。TripIt希望您发送oauth_令牌，以及请求url中的oauth_回调。记录UIWebview正在加载的请求，以准确查看发送到TripIt服务器的内容

在您的情况下，它可能如下所示：

https://m.tripit.com/oauth/authorize?oauth_token=<THE TOKEN HERE>

https://m.tripit.com/oauth/authorize?oauth_token=<THE TOKEN HERE>&oauth_callback=<YOUR CALLBACK URL>

https://m.tripit.com/oauth/authorize?oauth_token=

当它看起来像这样时：

https://m.tripit.com/oauth/authorize?oauth_token=<THE TOKEN HERE>

https://m.tripit.com/oauth/authorize?oauth_token=<THE TOKEN HERE>&oauth_callback=<YOUR CALLBACK URL>

https://m.tripit.com/oauth/authorize?oauth_token=&oauth_callback=

将回调URL追加到原始请求后，您将看到登录/授权屏幕加载，而不是“访问请求失败”

此外，这可能会帮助那些对与TripIt和OAuth 1.0集成感到困惑的人。
