OAuth访问令牌请求失败(NSErrorFailingURLStringKey)

我在OAuth流程中完成了以下步骤:
1)请求令牌
2)授权令牌
3)接收PIN号码

我无法工作的是使用我收到的PIN获取访问令牌。它始终会点击我的accessTokenTicket:didFailWithError选择器。

以下是传递给它的网址:
http://www.formspring.me/oauth/access_token?oauth_token=TOKEN_KEY_HERE&oauth_verifier=PIN_HERE

这是被调用的代码:

- (void)successfulAuthorizationWithPin:(NSString *)pin {
    NSLog(@"successfulAuthorizationWithPin:%@", pin);<br>
    OAMutableURLRequest *request;<br>
    OADataFetcher *fetcher;

    NSURL *url = [NSURL URLWithString:kOAuthAccessTokenURL];

    request = [[[OAMutableURLRequest alloc] initWithURL:url
                                               consumer:self.consumer
                                                  token:self.accessToken
                                                  realm:nil
                                      signatureProvider:nil] autorelease];

    OARequestParameter *p0 = [[OARequestParameter alloc] initWithName:@"oauth_token" value:self.accessToken.key];
    OARequestParameter *p1 = [[OARequestParameter alloc] initWithName:@"oauth_verifier"
                                                                value:pin];

    NSArray *params = [NSArray arrayWithObjects:p0, p1, nil];
    [request setParameters:params];
    [request prepare];

    NSLog(@"%@", request.URL);

    fetcher = [[[OADataFetcher alloc] init] autorelease];

    [fetcher fetchDataWithRequest:request
                         delegate:self
                didFinishSelector:@selector(accessTokenTicket:didFinishWithData:)
                  didFailSelector:@selector(accessTokenTicket:didFailWithError:)];

    [p0 release];
    [p1 release];
}

didFail方法(只是错误的NSLog)会产生此错误:

Error Domain=NSURLErrorDomain Code=-1012 "The operation couldn’t be completed. (NSURLErrorDomain error -1012.)" UserInfo=0x6160c20 {NSErrorFailingURLKey=http://www.formspring.me/oauth/access_token?oauth_token=TOKEN_KEY_HERE&oauth_verifier=PIN_HERE, NSErrorFailingURLStringKey=http://www.formspring.me/oauth/access_token?oauth_token=TOKEN_KEY_HERE&oauth_verifier=PIN_HERE, NSUnderlyingError=0x61321f0 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1012.)"}

我是否将网址格式错误或提供错误或不足的参数?

谢谢!

您是否检查生成的oauth令牌是否正确?我建议从那里开始。 Here's是检查OAuth令牌的好资源。

如果出现身份验证错误,则会显示该消息。通过Netflix Oauth验证生成URL并在浏览器上运行。看看它是否加载。
