iOS Twitter SLRequest返回url域错误-1012

Question

我正在尝试执行反向oauth以获取服务器的twitter访问令牌。

我想通了如何提交请求和接收响应，但是当我做，它给了我这个错误：

Error: The operation couldn’t be completed. (NSURLErrorDomain error -1012.) 

我看这件事，并说，这意味着用户取消了请求。我不知道这是如何可能的，我不知道如何解决它。

这里是我的代码：

NSTimeInterval timeStamp = [[NSDate date] timeIntervalSince1970]; 
    NSNumber *timeStampObj = [NSNumber numberWithDouble: timeStamp]; 

    NSString *oauth_nonce = [self genRandStringLength:32]; 
    NSString *oauth_timestamp = [timeStampObj stringValue]; 

    NSURL *feedURL = [NSURL URLWithString:@"https://api.twitter.com/oauth/request_token"]; 

    NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys: @"my key here", @"oauth_consumer_key", oauth_nonce, @"oauth_nonce", @"HMAC-SHA1", @"oauth_signature_method", oauth_timestamp, @"oauth_timestamp", @"1.0", @"oauth_version", @"reverse_auth", @"x_auth_mode", nil]; 

    SLRequest *twitterFeed = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:feedURL parameters:parameters]; 

    twitterFeed.account = self.userAccount; 


    // Making the request 

    [twitterFeed performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { 
     dispatch_async(dispatch_get_main_queue(), ^{ 

      // Check if we reached the reate limit 

      if ([urlResponse statusCode] == 429) { 
       NSLog(@"Rate limit reached"); 
       return; 
      } 

      // Check if there was an error 

      if (error) { 
       NSLog(@"The Error is: %@", error.localizedDescription); 
       return; 
      } 

      // Check if there is some response data 
      if (responseData) { 

       NSLog(@"%@", responseData); 

      } 
     }); 
    }]; 

必须有一些简单的我失踪了，这是保持我未能完成的一个项目。任何帮助将是伟大的，谢谢！

当我向https://api.twitter.com/oauth/request_token发送请求时，遇到此问题，并在头中有一个额外的随机数和签名。具体来说，下面的代码给了我一个1012，但下一个代码块成功了。该代码改编自Sean Cook's Reverse Twitter Auth example。

/** 
* The first stage of Reverse Auth. 
* 
* In this step, we sign and send a request to Twitter to obtain an 
* Authorization: header which we will use in Step 2. 
* 
* @param completion The block to call when finished. Can be called on any thread. 
*/ 
- (void)_step1WithCompletion:(TWAPIHandler)completion 
{ 
    NSURL *url = [NSURL URLWithString:TW_OAUTH_URL_REQUEST_TOKEN]; 
    NSDictionary *dict = @{TW_X_AUTH_MODE_KEY: TW_X_AUTH_MODE_REVERSE_AUTH, 
          TW_OAUTH_NONCE:[self nonce], 
          TW_SIGNATURE_METHOD: TW_SIGNATURE_METHOD_VALUE, 
          }; 

    TWSignedRequest *step1Request = [[TWSignedRequest alloc] initWithURL:url parameters:dict requestMethod:TWSignedRequestMethodPOST]; 

    TWDLog(@"Step 1: Sending a request to %@\nparameters %@\n", url, dict); 

    [step1Request performRequestWithHandler:^(NSData *data, NSURLResponse *response, NSError *error) { 
     dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ 
      completion(data, error); 
     }); 
    } 

以下的工作。请注意0​​中的更改。

/**

* 
* In this step, we sign and send a request to Twitter to obtain an 
* Authorization: header which we will use in Step 2.

* @param completion The block to call when finished. Can be called on any thread.

{ 
    NSURL *url = [NSURL URLWithString:TW_OAUTH_URL_REQUEST_TOKEN]; 
    NSDictionary *dict = @{TW_X_AUTH_MODE_KEY: TW_X_AUTH_MODE_REVERSE_AUTH}; 

    TWSignedRequest *step1Request = [[TWSignedRequest alloc] initWithURL:url parameters:dict requestMethod:TWSignedRequestMethodPOST]; 

    TWDLog(@"Step 1: Sending a request to %@\nparameters %@\n", url, dict); 

    [step1Request performRequestWithHandler:^(NSData *data, NSURLResponse *response, NSError *error) { 
     dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ 
      completion(data, error); 
     }); 
    }

错误代码-1012可能是由于身份验证质询造成的。在我的情况下，Twitter帐户存在于设置中，但由于某种原因未登录。一旦我输入帐户的密码，一切都完美。
