Azure AD B2C getting oauthConnection Error: Bad Request

Question

在尝试集成 Azure AD B2C 时，我遇到了错误 "oauthConnection Error: Bad Request"。按照他们给定的样本 app 一切正常。但是在从工作示例应用程序中集成相同的复制粘贴代码，并尝试使用 Facebook 或 Google Plus 登录后，它抛出错误！我非常确定我在示例应用程序中使用的每个凭据对于我的应用程序都是相同的。对此有任何想法将不胜感激。这是我的代码，AppDelegate.m

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

@interface AppDelegate ()

@implementation AppDelegate

    return YES;
}

                                forKey:@"Content-Type"];

    // Azure B2C needs
    // kNXOAuth2AccountStoreConfigurationAdditionalAuthenticationParameters for
    // sending policy to the server,
    // therefore we use -setConfiguration:forAccountType:

如果有人在这方面遇到问题，这里是解决方案

转到 pod，NXOAuth2Client.m 并替换方法 - (void)requestTokenWithAuthGrant:(NSString *)authGrant redirectURL:(NSURL *)redirectURL; 使用以下代码

- (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;
}
