Azure AD B2C獲取oauthConnection錯誤：錯誤請求

Question

嘗試集成Azure AD B2C時，我遇到了一個錯誤「oauthConnection錯誤：錯誤的請求」。按照他們的樣品app它一切正常。但是，從工作示例應用程序中集成相同的複製粘貼代碼並嘗試使用Facebook或Google Plus，它會引發錯誤！我非常肯定，我在示例應用程序中使用的每個憑證都與我的應用程序相同。任何關於這個想法將不勝感激。這裏是我的代碼，AppDelegate.m

#import "AppData.h" 
#import "NXOAuth2.h" 
#import "AppDelegate.h" 

@interface AppDelegate() 

@end 

@implementation AppDelegate 


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 


    [self setupOAuth2AccountStore]; 

    // Override point for customization after application launch. 
    return YES; 
} 

- (void)setupOAuth2AccountStore { 
    AppData *data = [AppData getInstance]; // The singleton we use to get the settings 

    NSDictionary *customHeaders = 
    [NSDictionary dictionaryWithObject:@"application/x-www-form-urlencoded" 
           forKey:@"Content-Type"]; 

    // Azure B2C needs 
    // kNXOAuth2AccountStoreConfigurationAdditionalAuthenticationParameters for 
    // sending policy to the server, 
    // therefore we use -setConfiguration:forAccountType: 
    NSDictionary *B2cConfigDict = @{ 
            kNXOAuth2AccountStoreConfigurationClientID : data.clientID, 
            kNXOAuth2AccountStoreConfigurationSecret : data.clientSecret, 
            kNXOAuth2AccountStoreConfigurationScope : 
             [NSSet setWithObjects:@"openid", data.clientID, nil], 
            kNXOAuth2AccountStoreConfigurationAuthorizeURL : 
             [NSURL URLWithString:data.authURL], 
            kNXOAuth2AccountStoreConfigurationTokenURL :

            };

在情況下，如果有人在此跌倒，在這裏是解決方案

進入吊艙，NXOAuth2Client.m與下面的代碼

- (void)requestTokenWithAuthGrant:(NSString *)authGrant redirectURL:(NSURL *)redirectURL; 
{ 
    NSAssert1(!authConnection, @"authConnection already running with: %@", authConnection); 

    NSMutableURLRequest *tokenRequest = [NSMutableURLRequest requestWithURL:tokenURL]; 
    [tokenRequest setHTTPMethod:self.tokenRequestHTTPMethod]; 
    [authConnection cancel]; // just to be sure 

    self.authenticating = YES; 

    NSMutableDictionary *parameters = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
             @"authorization_code", @"grant_type", 
             clientId, @"client_id", 
             // clientSecret, @"client_secret", 
             [redirectURL absoluteString], @"redirect_uri", 
             authGrant, @"code", 
             nil]; 
    if (self.desiredScope) { 
     [parameters setObject:[[self.desiredScope allObjects] componentsJoinedByString:@" "] forKey:@"scope"]; 
    } 

    if (self.customHeaderFields) { 
     [self.customHeaderFields enumerateKeysAndObjectsUsingBlock:^(NSString *key, NSString *obj, BOOL *stop) { 
      [tokenRequest addValue:obj forHTTPHeaderField:key]; 
     }]; 
    } 

    if (self.additionalAuthenticationParameters) { 
     [parameters addEntriesFromDictionary:self.additionalAuthenticationParameters]; 
    } 

    authConnection = [[NXOAuth2Connection alloc] initWithRequest:tokenRequest 
               requestParameters:parameters 
                oauthClient:self 
                 delegate:self]; 
    authConnection.context = NXOAuth2ClientConnectionContextTokenRequest; 
} 

談到clientSecret解決問題
