我有一个情况,我正在做一个对象的发布(不是一个管理的,只是一个NSObject派生的),但REST API的响应不是要发布的对象的
JSON表示形式.这还有别的东西.是否可以处理这个？
说我发布一个对象(JSON)：
{
"prop1" : 123,"prop2" : 5
}
而且如果不是具有属性prop1和prop2的对象(如RestKit预期的那样),而是其他的东西：
{
"data" : [1,2,3,4,5,6],"message" : "hello world"
}
我已经看到一些例子,其中将operation.targetobject设置为nil,但(我相信)这只是在Core Data管理的场景中.
我正在尝试像这样简单的东西：
RKObjectRequestOperation *operation = [self.objectManager appropriateObjectRequestOperationWithObject:body method:RKRequestMethodPOST path:@"items" parameters:nil];
[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation,RKMappingResult *result) {
// success is called,but the result does not contain what the response JSON is
} failure:^(RKObjectRequestOperation *operation,NSError *error) {
// failure
}];
[operation setwillMapDeserializedResponseBlock:^id(id deserializedResponseBody) {
// deserializedResponseBody is always nil
}];
[operation start];
我以为我可以看看setwillMapDeserializedResponseBlock中的响应内容,但总是为零.
因为发布的对象具有prop1和prop2属性,以及RestKit默认情况下的工作原理,它期望具有所述属性的JSON.但是,由于结果与发布的对象无关,所以prop1和prop2只是零(我不在乎).
顺便说一下,我已经正确地设置了请求映射,所以在操作对象中传递的正文正确映射我的NSObject并以正确的JSON格式发送给服务器.
有没有办法,我可以用RestKit打电话,手动拔出我正在寻找的成功事件？即使它是JSON响应的字典表示法？
解决方法
我只是为您的回应创建一个新对象,并将您的回复映射到该对象.
对象
@interface MYRequest : NSObject @property NSNumber *prop1; @property NSNumber *prop2; @end @interface MYResponse : NSObject @property NSArray *data; @property Nsstring *message; @end
映射
RKObjectMapping *requestMapping = [RKObjectMapping requestMapping]; [requestMapping addAttributeMappingsFromArray:@[@"prop1",@"prop2"]]; RKObjectMapping *responseMapping = [RKObjectMapping mappingForClass:[MYResponse class]]; [requestMapping addAttributeMappingsFromArray:@[@"data",@"message"]];
叙
RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:requestMapping
objectClass:[MYRequest class]
rootKeyPath:nil
method:RKRequestMethodPOST];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:responseMapping
method:RKRequestMethodPOST
pathPattern:@"items"
keyPath:nil
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
对象管理器
[self.objectManager addRequestDescriptor:requestDescriptor]; [self.objectManager addResponseDescriptor:responseDescriptor];
执行
MYRequest *body = [MYRequest new];
[body setProp1:@123];
[body setProp2:@5];
[self.objectManager postObject:body
path:@"items"
parameters:nil
success:^(RKObjectRequestOperation *operation,RKMappingResult *mappingResult) {
MYResponse *result = [mappingResult firstObject];
NSLog(@"Data: %@\nMessage: %@",[result data],[result message]);
}
failure:^(RKObjectRequestOperation *operation,NSError *error) {
NSLog(@"Error: %@",error);
}];
