【问题描述】：

我正在使用 AFNetworking 2.0，但遇到了问题。

我正在尝试将 json 中的数组放入服务器。

我正在发布类似的数组（请参阅下面的代码）。我将以下数组添加到 Json 参数以发送到服务器：

themes =     (
    "Fashion - Men",
    Kids,
    "Styling / Hair"
);

这会被发送到服务器：

id = 654;
tags = test;
themes =     (
    "Fashion - Men",
    Kids,
    "Styling / Hair"
);

但是服务器收到这样的 json 是错误的：

'id': '654', 'themes[]': ['Kids', 'Styling / Hair', 'Accessories - Women'], 'tags': 'test'

AFNetworking 在发送的 json 中按主题放置 [] 方括号，例如主题 []，因此 cal 是正确的，除了这个：主题 []

不知道如何解决这个问题。

- (void) piccMedia: (NSString*) aPiccId Tags: (NSString *) aTags Themes: (NSMutableArray *) anThemes
           success:(void (^)(NSArray *response))success
           failure:(void (^)(NSError *error))failure


    NSMutableDictionary * params = [[NSMutableDictionary alloc] init];
    [params setObject: @"654" forKey:@"id"];
    [params setObject: aTags forKey:@"tags"];
    [params setObject: anThemes forKey:@"themes"];

    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    NSString *piccingAuthToken = [prefs stringForKey:@"piccingAuthToken"];
    NSString *piccingUsername = [prefs stringForKey:@"piccingUsername"];
    NSLog(@"piccingAuthToken %@ %@", piccingAuthToken,piccingUsername);

    NSString *postQueryString = [NSString stringWithFormat:@"http://dev.com/services/rest/profiles/%@/media",piccingUsername];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    manager.responseSerializer = [JSONResponseSerializerWithData serializer];

    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/plain", @"text/html", nil];
    manager.responseSerializer = [JSONResponseSerializerWithData serializerWithReadingOptions:NSJSONReadingAllowFragments | NSJSONReadingMutableContainers | NSJSONReadingMutableLeaves];
    [manager.requestSerializer setValue:piccingAuthToken forHTTPHeaderField:@"x-authtoken"];

    [manager PUT:postQueryString parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) 

        success(responseObject);

     failure:^(AFHTTPRequestOperation *operation, NSError *error) 

        id json = error.userInfo [JSONResponseSerializerWithDataKey];
        failure(json);
    ];

【问题讨论】：

NSLog params 并将输出添加到您的答案中。

params can more easily be created: NSDictionary *params = @ @"id":@"654", @"tags":aTags, @"themes":anThemes;`

什么是JSONResponseSerializerWithData？ AFNetworking 没有。可以发一下代码吗？

JSONResponseSerializerWithData 只是帮助我更好地解释我的错误

抱歉。 JSONResponseSerializerWithData 确实带有 AFNetworking

【参考方案1】：

您应该将 requestSerializer 设置为 AFJSONRequestSerializer

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
[manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) 
    NSLog(@"JSON: %@", responseObject);
 failure:^(AFHTTPRequestOperation *operation, NSError *error) 
    NSLog(@"Error: %@", error);
];
