RestKit - POST 响应对象映射

发布于 2024-12-06 10:50:20 字数 989 浏览 1 评论 0原文

我的 RESTful web 服务（Rails）上有方法“getBuses”。该方法需要返回我的 JSON 格式的公交车列表。但是，当我发送“/getBuses.json”请求时，我需要发送

params = [NSDictionary 
dictionaryWithObjectsAndKeys: @"2011-08-16", @"datum", @"TRUE", 
@"fromSerbia", nil];

我正在发布参数，因为我需要过滤响应（仅针对特定特定日期的游览）。然后，我期待这样的响应：

{ 
  "buses" : [ { 
    "bus_number" : "1", 
    "created_at" : "2011-08-15T23:07:52Z", 
    "id" : 1, 
    "lat" : 44.815, 
    "long" : 20.4665, 
    "model" : "Setra", 
    "registar_number" : "123456", 
    "seats" : 50, 
    "tour_id" : 1, 
    "updated_at" : "2011-08-15T23:07:52Z" 
  }, { 
    "bus_number" : "2", 
    "created_at" : "2011-08-15T23:07:52Z", 
    "id" : 2, 
    "lat" : 44.812, 
    "long" : 20.465, 
    "model" : "Mercedes", 
    "registar_number" : "2234", 
    "seats" : 60, 
    "tour_id" : 1, 
    "updated_at" : "2011-08-15T23:07:52Z" 
  } ] 
}

我只需要带有 Bus 对象的 NSArray 。 你能给我代码示例如何发出此请求并使用 RestKit 进行对象映射吗？

原文

I have method "getBuses" on my RESTful webservice (Rails). That method needs to return
me list of buses in JSON. But, when I sending request for "/getBuses.json" I
need to send

params = [NSDictionary 
dictionaryWithObjectsAndKeys: @"2011-08-16", @"datum", @"TRUE", 
@"fromSerbia", nil];

I'm posting params because I need filtered response (just for specific
tour on specific date).
Then, I expecting response like this:

{ 
  "buses" : [ { 
    "bus_number" : "1", 
    "created_at" : "2011-08-15T23:07:52Z", 
    "id" : 1, 
    "lat" : 44.815, 
    "long" : 20.4665, 
    "model" : "Setra", 
    "registar_number" : "123456", 
    "seats" : 50, 
    "tour_id" : 1, 
    "updated_at" : "2011-08-15T23:07:52Z" 
  }, { 
    "bus_number" : "2", 
    "created_at" : "2011-08-15T23:07:52Z", 
    "id" : 2, 
    "lat" : 44.812, 
    "long" : 20.465, 
    "model" : "Mercedes", 
    "registar_number" : "2234", 
    "seats" : 60, 
    "tour_id" : 1, 
    "updated_at" : "2011-08-15T23:07:52Z" 
  } ] 
}

I just need NSArray with Bus objects.
Can you give me code example how to make this request and make object mapping with RestKit?

正如我在 IRC 频道中告诉您的，在 RKClient 实例中，您可以使用以下方法：

(NSURL *)URLForResourcePath:(NSString *)resourcePath queryParams:(NSDictionary *)queryParams

所以您应该这样做：

[objectManager.mappingProvider setMapping:busesMapping forKeyPath:@"buses"];

params = [NSDictionary dictionaryWithObjectsAndKeys: @"2011-08-16", @"datum", @"TRUE", @"fromSerbia", nil];
NSURL *someURL = [objectManager.client URLForResourcePath:@"/service/getLocations.json" queryParams:params];

[objectManager loadObjectsAtResourcePath:[someURL absoluteString] delegate:self];

该方法构建一个有效的使用资源路径和您作为参数提供的参数的 URL。然后您需要使用 NSURL 对象的absoluteString 将其设置回来。希望这有帮助！

As I told you in the IRC Channel, in your RKClient instance you can use this method:

(NSURL *)URLForResourcePath:(NSString *)resourcePath queryParams:(NSDictionary *)queryParams

So you should do it like this:

[objectManager.mappingProvider setMapping:busesMapping forKeyPath:@"buses"];

params = [NSDictionary dictionaryWithObjectsAndKeys: @"2011-08-16", @"datum", @"TRUE", @"fromSerbia", nil];
NSURL *someURL = [objectManager.client URLForResourcePath:@"/service/getLocations.json" queryParams:params];

[objectManager loadObjectsAtResourcePath:[someURL absoluteString] delegate:self];

That method builds a valid URL using the resourcePath and the parameters you give as parameter. And then you need to set it back using the absoluteString of the NSURL object. Hope this helps!
