RESTkit例外：在搜索的关键路径中找不到可映射的对象表示

Question

我正面临一些问题。服务器收到请求但映射未正确处理。我不明白我做错了什么。

代码：

RKObjectMapping* objectMapping = [RKObjectMapping mappingForClass:[ResponseModel class]]; 
    [objectMapping addAttributeMappingsFromArray:@[@"success", @"errors"]]; 
    [objectMapping addPropertyMapping:[RKRelationshipMapping 
             relationshipMappingFromKeyPath:@"data" 
                  toKeyPath:@"data"

    RKResponseDescriptor* responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:objectMapping 
                      method:RKRequestMethodPOST

    RKObjectManager *objectManager = [[RKObjectManager alloc] initWithHTTPClient:client]; 
    [objectManager addResponseDescriptor:responseDescriptor]; 
    RKLogConfigureByName("RestKit/ObjectMapping", RKLogLevelTrace); 

    [objectManager getObjectsAtPath:responseDescriptor.pathPattern parameters:params success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) { 
     NSLog(@"success"); 
    } failure:^(RKObjectRequestOperation *operation, NSError *error) { 
     NSLog(@"failure"); 
    }]; 

ResponseModel接口：

@interface ResponseModel : NSObject 

@property NSString* success; 
@property id data; 
@property (strong, nonatomic) NSArray* errors; 

@end 

请求：

{ 
    "success": "true", 
    "data": [], 
    "errors": [] 
} 

为什么RESTKIT总是调用失败块？

Answer 1

可能你只需要改变这一行，因为它看起来像你设置一个无响应描述符？

[objectManager addResponseDescriptor:self.responseDescriptor]; 

所以删除self.，因为它似乎你不设置实例变量，你只是有一个局部变量。

您还使用method:RKRequestMethodPOST但制作与getObjectsAtPath所以RestKit未能与POST匹配GET请求。
