Question

我正在使用AFNetworking来拨打服务器。服务器已启用NTLM身份验证。我正在使用 setWillSendRequestForAuthenticationChallengeBlock 来处理该身份验证。

我的问题是，当我第一次打电话给服务器时，它完美无缺。但是，当我再次对服务器进行相同的调用时，我得到错误请求（400）错误。这是我的代码：

-(AFHTTPRequestOperation *)POST:(NSString *)URLString parameters:(id)parameters success:(void (^)(AFHTTPRequestOperation *, id))success failure:(void (^)(AFHTTPRequestOperation *, NSError *))failure {

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",[self.baseURL absoluteString],URLString]]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:[NSJSONSerialization dataWithJSONObject:parameters options:NSJSONWritingPrettyPrinted error:nil]]
;

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.shouldUseCredentialStorage = NO;

operation.responseSerializer = [AFJSONResponseSerializer serializer];

[operation setCompletionBlockWithSuccess:success failure:failure];

[self addChallengeBlockForOperation:operation failure:^(NSError *error) {
    failure(operation,error);
}];

//[self.operationQueue addOperation:operation];
[operation start];

return operation;
}

- (void)addChallengeBlockForOperation:(AFHTTPRequestOperation *)operation failure:(void (^)(NSError *error))failure {
[operation setWillSendRequestForAuthenticationChallengeBlock:^(NSURLConnection *connection, NSURLAuthenticationChallenge *challenge) {
    if( [[challenge protectionSpace] authenticationMethod] == NSURLAuthenticationMethodNTLM )
    {
        if( [challenge previousFailureCount] > 0 )
        {
            // Avoid too many failed authentication attempts which could lock out the user
            [[challenge sender] cancelAuthenticationChallenge:challenge];
        }
        else
        {
            [[challenge sender] useCredential:[NSURLCredential credentialWithUser:[DataManager sharedInstance].fullUserName password:[DataManager sharedInstance].password persistence:NSURLCredentialPersistenceSynchronizable] forAuthenticationChallenge:challenge];
        }
    }
    else
    {
        // Authenticate in other ways than NTLM if desired or cancel the auth like this:
        [[challenge sender] cancelAuthenticationChallenge:challenge];
    }
}];
}

我知道我可以通过将 text / html 添加到已接受的类型来删除此错误，但这不是解决方案。我也应该能够第二次获得JSON响应。我还得到 Stream xxxxx在第一次通话时在控制台上打开之前发送一个事件，在第二次通话时发送两次。

为了安全起见，我在日志中隐藏了URL。这是我的日志：
