我正在遵循foursquare authen指南,但我仍然有问题
这是我的代码
- (void)viewDidLoad
{
[super viewDidLoad];
self.webView.delegate = self;
NSString *clientID = @"XXX";
NSString *redirectURI = @"http://www.example.com";
NSString *authenticateURLString = [NSString stringWithFormat:@"https://foursquare.com/oauth2/authenticate?client_id=%@&response_type=token&redirect_uri=%@", clientID, redirectURI];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:authenticateURLString]];
[self.webView loadRequest:request];
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if ([request.URL.scheme isEqualToString:@"itms-apps"]) {
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
}
return YES;
}
- (void)webViewDidFinishLoad:(UIWebView *)webView {
NSString *URLString = [[self.webView.request URL] absoluteString];
NSLog(@"--> %@", URLString);
if ([URLString rangeOfString:@"access_token="].location != NSNotFound) {
NSString *accessToken = [[URLString componentsSeparatedByString:@"="] lastObject];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:accessToken forKey:@"access_token"];
[defaults synchronize];
[self dismissViewControllerAnimated:YES completion:nil];
}
}
但 NSLog 的输出仅为http://www.example.com。它没有访问令牌返回。我做错什么了吗?
我在桌面谷歌浏览器中打开这个链接并且访问令牌成功返回。(www.example.com#access_token=XXX)但是我在 iPhone 模拟器的 safari 中打开了这个链接,它只返回了 url。
感谢帮助。
