iphone - 使用 TWRequest 的推特更新给出 403 错误

Question

我正在使用以下代码使用 iOS 5 twitter API 在用户的时间线中发推文

//创建一个帐户存储对象。 ACAccountStore *accountStore = [[ACAccountStore alloc] init];

// Create an account type that ensures Twitter accounts are retrieved.
ACAccountType *accountType =  [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];

// Request access from the user to use their Twitter accounts.
[accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) 
 {
     if(granted) 
     {
         // Get the list of Twitter accounts.
         NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];

         // For the sake of brevity, we'll assume there is only one Twitter account present.
         // You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present.
         // Grab the initial Twitter account to tweet from.
         ACAccount *twitterAccount = [accountsArray objectAtIndex:buttonIndex];
         // Create a request, which in this example, posts a tweet to the user's timeline.
         // This example uses version 1 of the Twitter API.
         // This may need to be changed to whichever version is currently appropriate.


         TWRequest *postRequest = [[TWRequest alloc] initWithURL:[NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"] parameters:[NSDictionary dictionaryWithObject:@"hello this is a tweet" forKey:@"status"] requestMethod:TWRequestMethodPOST];

         // Set the account used to post the tweet.
         [postRequest setAccount:twitterAccount];

         // Perform the request created above and create a handler block to handle the response.
         [postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) 
          {

              NSString *output = [NSString stringWithFormat:@"%i", [urlResponse statusCode]];
              [self performSelectorOnMainThread:@selector(TweetStatus:) withObject:output waitUntilDone:NO];
          }];
     }
 }];

我已经使用这种方法测试应用程序一个多月了，它过去工作正常，没有任何问题。

几周后它开始在以下方法中返回 403 错误。

[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) 
          {

              NSString *output = [NSString stringWithFormat:@"%i", [urlResponse statusCode]];
              [self performSelectorOnMainThread:@selector(TweetStatus:) withObject:output waitUntilDone:NO];
          }];

它给出了以下错误:

Error Domain=NSURLErrorDomain Code=-1012 "The operation couldn’t be completed. (NSURLErrorDomain error -1012.)" UserInfo=0x1f8b3250 {NSErrorFailingURLKey=http://api.twitter.com/1/statuses/update.json, NSErrorFailingURLStringKey=http://api.twitter.com/1/statuses/update.json, NSUnderlyingError=0x1ed19f90 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1012

我搜索了很多，但找不到解决此问题的方法或真正原因。

请牢记一些可能有助于理解问题的注意事项:

• 该应用程序用于测试，这意味着我们使用了 Twitter 共享并与其他用户提及了很多。
• 共享内容并不总是相同的，因此不会出现重复问题，因为我们经常清理时间线。

谢谢

您尝试发送推文的文本必须与您之前发布的推文相似，因此您会收到此错误。根据文档 here , 不能多次发布相同的文本。

编辑:

这也可能取决于他们网站上提到的推文总数。
