ios - Mashape Objective-C for iOS - MashapeResponse to JSON Object

Question

我正在通过 Mashape.com 使用名为 Lamda (https://www.mashape.com/lambda) 的 API，这是一种人脸识别 API。

当我从识别请求中得到结果时，它会给我一个“MashapeRespose”对象。

我无法将此 MashapeResponse 或其任何部分转换为 JSON 对象。

当我打电话

NSLog(@"des=%@", [response body]);

我把这个打印出来

                            uid = "olivier@MICClientele";
                        },
                                                {

                                                {
                            confidence = "0.161";
                            prediction = damien;
                            uid = "damien@MICClientele";

                                                {
                            confidence = "0.065";
                            prediction = egle;
                            uid = "egle@MICClientele";
                        },
                                                {
                            confidence = "0.065";
                            prediction = gareth;
                            uid = "gareth@MICClientele";
                        }
                    );
                    width = 112;
                }
            );
            url = "http://api.lambdal.com/static/uploads/img05Xv8N.png";
            width = 200;
        }
    );
    status = success;
} 

显然这不是有效的 JSON。

这里是MashapeResponse.h的内容

#import "MashapeResponse.h"

@interface MashapeResponse ()
@property (readwrite, retain) NSData* rawBody;
@property (readwrite) NSDictionary* headers;
@property (readwrite) int code;
@end

@implementation MashapeResponse

@synthesize rawBody;
@synthesize headers;
@synthesize code;
@synthesize body;

-(MashapeResponse*)initWithResponse:(int)httpCode headers:(NSDictionary*) httpHeaders rawBody:(NSData*) httpRawBody {
    self = [super init];
    [self setCode:httpCode];
    [self setHeaders:httpHeaders];
    [self setRawBody:httpRawBody];
    return self;
}

@end 

有没有人能够在 iOS 上使用 Mashape 并能够转换成 JSON 对象？

我可以使用子字符串来获取我想要的信息，但这不是它应该的工作方式，因为文档声明它应该是一个 json 响应..

至少可以说非常沮丧......

附言。我已经将这个问题邮寄给 Mashape 支持，所以如果我在有人在这里发布答案之前得到解决方案，我会把它添加到这篇文章中。

编辑:

当我打电话

id status = [response valueForKey:@"status"];
NSLog(@"status=%@", [status description]);
id photos = [response valueForKey:@"photos"];
NSLog(@"photos=%@", [photos description]);

我得到这个异常

2012-09-20 16:53:20.609 Clientele[5160:707] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<MashapeJsonObjectResponse 0x3d2810> valueForUndefinedKey:]: this class is not key value coding-compliant for the key status.'

首先感谢 Dcritelli 对这个问题的帮助..

我收到了 Mashape 关于我的问题的回复，他们向我发送了这封电子邮件作为回复。

Hi Damien,

The [response body] method already returns a parsed JSON object. If you need the raw response in bytes (that is a NSData* object), you can get it by invoking [response rawBody]. You can convert a NSData* to NSString* if you want.

Given that [response body] returns the parsed JSON object, for example to get the "url" property of the first photo in the "photos" array, you would write:

 NSArray* photos = [[response body] objectForKey:@"photos"];
 NSDictionary* firstPhoto = [photos objectAtIndex:0];
 NSString* url = [firstPhoto objectForKey:@"url"];
 NSLog(@"URL of the first photo is: %@", url);

We apologize if the docs were confusing, we updated them and you can read the new revision here: https://www.mashape.com/docs/consume/objectivec

Let us know if you need additional help, Cheers

因此，他们不仅回复了解决方案，还更新了文档。
