Objective c 如何将AF2与摘要身份验证一起使用

我一直在搜索“AFNetworking 2 with Digest Authentication”有一段时间了，没有找到关于它的有用讨论（除了，但不幸的是，它看起来像是针对AFNetworking 1的）

以下是我的无身份验证代码：

NSString* apiURL = @"https://api.example.com/WS.asmx";
AFHTTPSessionManager* manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager
    GET:apiURL 
    parameters: [NSDictionary dictionaryWithObjectsAndKeys:@"ID", 1234 , nil]
    success:^(NSURLSessionDataTask *task, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    }
    failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"WS request failed: %@", error);
    }
];

在哪里以及如何消化身份验证代码？

这个问题有点老了，但我不得不这样做，我找不到任何内置的方法来处理它。 我使用的解决方案是编辑AFURLSessionManager.m中的AFNetworkings。 基本上，您可以修改此委托方法以支持http摘要，下面是一个完整的示例

    - (void)URLSession:(NSURLSession *)session
                  task:(NSURLSessionTask *)task
    didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge
     completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler
    {
        NSURLSessionAuthChallengeDisposition disposition = NSURLSessionAuthChallengePerformDefaultHandling;
        __block NSURLCredential *credential = nil;

        if (self.taskDidReceiveAuthenticationChallenge) {
            disposition = self.taskDidReceiveAuthenticationChallenge(session, task, challenge, &credential);
        } else {
            if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
                if ([self.securityPolicy evaluateServerTrust:challenge.protectionSpace.serverTrust forDomain:challenge.protectionSpace.host]) {
                    disposition = NSURLSessionAuthChallengeUseCredential;
                    credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
                } else {
                    disposition = NSURLSessionAuthChallengeCancelAuthenticationChallenge;
                }
            } else if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodHTTPDigest]) {
                NSDictionary *userkeys = [[NSURLCredentialStorage sharedCredentialStorage] credentialsForProtectionSpace:challenge.protectionSpace];

                credential = [userkeys objectForKey:(NSString *)[[userkeys allKeys] objectAtIndex: 0]];
                if (credential) {
                    disposition = NSURLSessionAuthChallengeUseCredential;
                } else {
                    disposition = NSURLSessionAuthChallengePerformDefaultHandling;
                }
            }else {
                disposition = NSURLSessionAuthChallengePerformDefaultHandling;
            }
        }

        if (completionHandler) {
            completionHandler(disposition, credential);
        }
    }

在此质询之前，您需要向sharedCredentialStorage添加凭据。 您可以查看apple文档，因为这相当简单，但要确保保护空间完全匹配，包括领域。

我希望它能帮助别人。

我只是使用了下面的代码，工作得很好

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSURLCredential *credential = [[NSURLCredential alloc] initWithUser:@"Username" password:@"Password" persistence:NSURLCredentialPersistenceForSession];
[manager setCredential:credential];

我最近升级到AFNetworking-3，不再提供

NSURLConnection

支持

当我切换到

NSURLSession

时，我遇到了同样的问题

谢谢你，鲍勃，编辑AFNetworkings

AFURLSessionManager.m

对我来说很好

但在那之后，我找到了一个更简单的方法，如果设置了

self.taskdireceptiveauthenticationchallenge

，我们就不必更改网络代码

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

NSURLCredential *myCredential = [[NSURLCredential alloc] initWithUser:@"username" password:@"password" persistence:NSURLCredentialPersistenceForSession];

[manager setTaskDidReceiveAuthenticationChallengeBlock:^NSURLSessionAuthChallengeDisposition(NSURLSession * _Nonnull session, NSURLSessionTask * _Nonnull task, NSURLAuthenticationChallenge * _Nonnull challenge, NSURLCredential *__autoreleasing  _Nullable * _Nullable credential) {
    if (challenge.previousFailureCount == 0) {
        *credential = myCredential;
        return NSURLSessionAuthChallengeUseCredential;
    } else {
        return NSURLSessionAuthChallengePerformDefaultHandling;
    }
}];

我花了一段时间才弄明白这一点，但我没有看到AFNetworking 4.0的任何解决方案（4.0是必需的，因为它删除了不推荐的UIWebView，如果发现它，苹果现在会拒绝它），请这样做

NSURLCredential *myCredential = [[NSURLCredential alloc] initWithUser:username password:password persistence:NSURLCredentialPersistenceForSession];

[manager setAuthenticationChallengeHandler:^id _Nonnull(NSURLSession * _Nonnull session, NSURLSessionTask * _Nonnull task, NSURLAuthenticationChallenge * _Nonnull challenge, void (^ _Nonnull completionHandler)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable credential)) {
    if (challenge.previousFailureCount == 0) {
        return myCredential;
    } else {
        return @(NSURLSessionAuthChallengePerformDefaultHandling);
    }
}];
