OAuth在Temboo中的故障

Question

我正试图授权iOS和to中的用户使用Twitter。下面是我尝试的方法。

在我的SetttingsViewController类中，我有一个按钮，用户可以点击这个按钮开始TwitterAuthentication。我在一个名为TwitterClient的类中有TwitterClient方法，在一个名为TwitterFClient的类中有FinalizeOauth方法。这是我的课。

TwitterClient.m

-(void)runInitializeOAuthChoreo {
    // Instantiate the Choreo, using a previously instantiated TembooSession object, eg:
    TMBTembooSession *session = [[TMBTembooSession alloc] initWithAccount:@"prnk28" appKeyName:@"Floadt" andAppKeyValue:@"9b9031d182d7441da05f8214ba2c7170"];

    // Create the choreo object using your Temboo session
    TMBTwitter_OAuth_InitializeOAuth *initializeOAuthChoreo = [[TMBTwitter_OAuth_InitializeOAuth alloc] initWithSession:session];

    // Get Inputs object for the choreo
    TMBTwitter_OAuth_InitializeOAuth_Inputs *initializeOAuthInputs = [initializeOAuthChoreo newInputSet];

    // Set credential to use for execution
    [initializeOAuthInputs setCredential:@"Twitter"];

    // Set inputs
    [initializeOAuthInputs setForwardingURL:@"floadt://success"];

    // Execute choreo specifying this class as the choreo delegate
    [initializeOAuthChoreo executeWithInputs:initializeOAuthInputs delegate:self];
}

// TMBChoreographyDelegate method implementation - handle choreo errors
-(void)choreographyDidFailWithError:(NSError*)error {
    // Log error to the console
    NSLog(@"Error - %@", error);
}

// TMBChoreographyDelegate method implementation - choreo executed successfully
-(void)choreographyDidFinishExecuting:(TMBTwitter_OAuth_InitializeOAuth_ResultSet*)result {
    // Log results to the console
   // NSLog(@"%@", [result getAuthorizationURL]);
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[result getAuthorizationURL]]];

    NSUserDefaults *user = [NSUserDefaults standardUserDefaults];

    NSString *callbackid = [result getCallbackID];
    [user setObject:callbackid forKey:@"TwitterCallbackID"];
    [user synchronize];

    NSString *oauthtokensecret = [result getOAuthTokenSecret];
    [user setObject:oauthtokensecret forKey:@"TwitterTemporaryOAuth"];
    [user synchronize];

}

TwitterFClient.m

-(void)runFinalizeOAuthChoreo {
    // Instantiate the Choreo, using a previously instantiated TembooSession object, eg:
    TMBTembooSession *session = [[TMBTembooSession alloc] initWithAccount:@"prnk28" appKeyName:@"Floadt" andAppKeyValue:@"9b9031d182d7441da05f8214ba2c7170"];

    // Create the choreo object using your Temboo session
    TMBTwitter_OAuth_FinalizeOAuth *finalizeOAuthChoreo = [[TMBTwitter_OAuth_FinalizeOAuth alloc] initWithSession:session];

    // Get Inputs object for the choreo
    TMBTwitter_OAuth_FinalizeOAuth_Inputs *finalizeOAuthInputs = [finalizeOAuthChoreo newInputSet];

    // Set credential to use for execution
    [finalizeOAuthInputs setCredential:@"Twitter"];

    // Set inputs
    NSUserDefaults *user = [NSUserDefaults standardUserDefaults];
    NSString *tCall = [user stringForKey:@"TwitterCallbackID"];
    NSString *tTAuth = [user stringForKey:@"TwitterTemporaryOAuth"];
    [finalizeOAuthInputs setOAuthTokenSecret:tCall];
    [finalizeOAuthInputs setCallbackID:tTAuth];
    [finalizeOAuthInputs setConsumerKey:TWITTER_CONSUMER_KEY];
    [finalizeOAuthInputs setConsumerSecret:TWITTER_CONSUMER_SECRET];

    // Execute choreo specifying this class as the choreo delegate
    [finalizeOAuthChoreo executeWithInputs:finalizeOAuthInputs delegate:self];
}

// TMBChoreographyDelegate method implementation - handle choreo errors
-(void)choreographyDidFailWithError:(NSError*)error {
    // Log error to the console
    NSLog(@"Error - %@", error);
}

// TMBChoreographyDelegate method implementation - choreo executed successfully
-(void)choreographyDidFinishExecuting:(TMBTwitter_OAuth_FinalizeOAuth_ResultSet*)result {
    // Log results to the console
    NSLog(@"%@", [result getAccessTokenSecret]);
    NSLog(@"%@", [result getAccessToken]);
    NSLog(@"%@", [result getScreenName]);
    NSLog(@"%@", [result getUserID]);
}

这是两个客户端类。我相信，在Facebook的例子中，两者都是结合在一起的，这会是建议的做法吗？

无论如何，在SettingsViewController类中调用这些方法是这样的：

SettingsViewController.m

TwitterClient *twitter = [[TwitterClient alloc] init];
[twitter runInitializeOAuthChoreo];

当用户从Web浏览器返回时，我调用了FinalizeOAuth方法。这是如何在AppDelegate中说明的。

AppDelegate.m

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation
{

    NSString *daURL = [url absoluteString];
 //   NSString *instagram;
    NSString *twitter;

    twitter = [daURL substringWithRange: NSMakeRange (0, 16)];
   //  instagram = [daURL substringWithRange:NSMakeRange(0, 27)];

    if ([daURL isEqual: @"floadt://success"]) {
        TwitterFClient *fo = [[TwitterFClient alloc] init];
        [fo runFinalizeOAuthChoreo];
    }else{
        [[InstagramClient sharedClient] handleOAuthCallbackWithURL:url];
    }

    return YES;
}

我假设有一种更简单的方法来做这件事，我会对代码进行剧烈的修改！

看起来，这些值被反转了：

[finalizeOAuthInputs setOAuthTokenSecret:tCall];
[finalizeOAuthInputs setCallbackID:tTAuth];

此外，在finalize步骤中，您指定了您的Twitter凭据，但接下来您也要这样做：

[finalizeOAuthInputs setConsumerKey:TWITTER_CONSUMER_KEY];
[finalizeOAuthInputs setConsumerSecret:TWITTER_CONSUMER_SECRET];

这是不必要的，因为这些值存储在凭据中(从初始化-oauth流中使用它就可以看出这一点)。你可以完全删除这两行。如果他们因为某种原因不匹配，你的舞蹈表演就会失败。
