objective-c - Node.js bodyparser 无法准备好 AFNetworking POST 数组

Question

我正在尝试将包含数组的 JSON 消息发布到我的服务器。但是服务器无法识别数组中的元素。检查问题后，我发现了我认为的问题所在。

AF网络代码:

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:kServiceBaseUrl]];
manager.responseSerializer = [AFJSONResponseSerializer serializer];

[manager PUT:@"/api/createRubaway"
   parameters:myDictionary
      success:^(NSURLSessionDataTask *task, NSDictionary *responseObject)
     {/* stuff */}
      failure:^(NSURLSessionDataTask *task, NSError *error)
     {/* stuff */}
 ];

LLDB 打印出“myDictionary”:

{
    description = description;
    title = title;
    transitions =     (
                {
            idx = 0;
            resource =             {
                data = testdata;
                name = transition;
                type = image;
            };
            threshold = "0.75";
            type = rubaway;
        },
                {
            idx = 1;
            resource =             {
                data = testdata;
                name = transition;
                type = image;
            };
            threshold = "0.75";
            type = rubaway;
        }
    );
}

在 AFNetworking 序列化请求之后。如果我从 NSMutableRequest 打印出 HTTPBody，这就是它发送的内容(这是发送到我的服务器的内容):

description=description&title=title&transitions[][idx]=0&
transitions[][resource][data]=testdata&
transitions[][resource][name]=transition&
transitions[][resource][type]=image&
transitions[][threshold]=0.75&
transitions[][type]=rubaway&transitions[][idx]=1&
transitions[][resource][data]=testdata&
transitions[][resource][name]=transition&
transitions[][resource][type]=image&transitions[][threshold]=0.75&
transitions[][type]=rubaway

以上格式是否正确。作为我的服务器(Node.js - BodyParser)，我相信它会以这种格式出现 https://stackoverflow.com/a/18402556/623750

有没有办法改变 JSON 序列化器的格式？或者有没有办法配置 BodyParser 以接受上述格式？

谢谢，瑞安

您需要做的就是将 requestSerializer 设置为 AFJSONRequestSerializer，这将解决问题。

 [manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
 [manager setResponseSerializer:[AFJSONResponseSerializer serializer]];
