ios - 通过 AFNetworking 2.0 发送加密的 JSON

Question

我正在从 AFNetworking1 迁移到AFNetworking 2.0。`

我必须发送一个加密的 JSON，之前我们只发送一个 NSSTring，但现在我们发送一个 NSDictionary 作为 JSON 到 POST。我一直在寻找，但找不到如何为 2.0 版本做同样的事情。

这是之前的代码:

request = [NSMutableURLRequest requestWithURL:url];
    NSLog(@"url: %@", url);

    NSString *jsonStr = [[NSString alloc] initWithData:
                         [NSJSONSerialization dataWithJSONObject:params
                                                         options:NSJSONReadingMutableLeaves
                                                           error:nil]
                                              encoding:NSUTF8StringEncoding];

    NSLog(@"%@", jsonStr);

    NSData *requestData =  [jsonStr dataUsingEncoding:NSUTF8StringEncoding];//[NSData dataWithBytes:[jsonStr UTF8String] length:[jsonStr length]];


    [request setHTTPMethod:@"PUT"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:@"json" forHTTPHeaderField:@"Data-Type"];
    [request setValue:[NSString stringWithFormat:@"%d", [jsonStr length]] forHTTPHeaderField:@"Content-Length"];
    [request setValue:[self sha256:jsonStr] forHTTPHeaderField:@"X-Hash"];
    [request setHTTPBody: requestData];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request];
    [operation setAuthenticationChallengeBlock:^(NSURLConnection *connection, NSURLAuthenticationChallenge *challenge) {
        NSURLCredential *newCredential = [NSURLCredential credentialWithUser:USERNAME password:PASSWORD persistence:NSURLCredentialPersistenceForSession];
        [challenge.sender useCredential:newCredential forAuthenticationChallenge:challenge];
    }];

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id response) {

 }

我想在 AFNetworking 2.0.. 上找到相同的功能如您所见，我添加了一个 X-Hash header ，并发送了一个带有 sha256 函数的加密版本的 JSON。

谢谢。

NSURLCredential *credential = [NSURLCredential credentialWithUser:@"login" password:@"password" persistence:NSURLCredentialPersistenceForSession];
[operation setCredential:credential];
