Question

我正在使用的REST服务有两种不同的响应模式。

{
success: true,
data: { //all data goes here}
}

或

{
success: false,
error: "Error",
message: "some message"
}

我正在尝试配置RESTKit以返回我创建的某个错误对象，以存储错误响应和已配置的类（基于URL）for success = true case。

我正在尝试使用RKDynamicMapping来根据“成功”的价值来实现这一目标。

   - (RKDynamicMapping *)createCompatibleMapping:(NSDictionary *)successDictionary  withClass:(Class) class{
        NSMutableDictionary *withSuccessDictionary = [NSMutableDictionary dictionaryWithDictionary:successDictionary];
        [withSuccessDictionary addEntriesFromDictionary:@{@"success" : @"success"}];

    RKObjectMapping *successMapping = [RKObjectMapping mappingForClass:class];
    [successMapping addAttributeMappingsFromDictionary:withSuccessDictionary];

    RKObjectMapping *restErrorMapping = [RKObjectMapping mappingForClass:[RESTErrorObject class]];
    [restErrorMapping addAttributeMappingsFromDictionary:@{@"success" : @"success", @"error" : @"errorString", @"message" : @"message"}];

    RKDynamicMapping *dynamicMapping = [RKDynamicMapping new];


    [dynamicMapping addMatcher:[RKObjectMappingMatcher matcherWithKeyPath:@"success" expectedValue:[NSNumber numberWithBool:YES ] objectMapping:successMapping]];
    [dynamicMapping addMatcher:[RKObjectMappingMatcher matcherWithKeyPath:@"success" expectedValue:[NSNumber numberWithBool:NO ] objectMapping:restErrorMapping]];
    return dynamicMapping;
}

然后我将它添加到响应描述符中，如下所示：

RKResponseDescriptor * cardDetailsResponseDescriptor2  = [RKResponseDescriptor responseDescriptorWithMapping:cardDetailsResponseMapping method:RKRequestMethodGET
                                                                                                    pathPattern:@"services/details/:cardNumber" keyPath:@"data"
                                                                                                    statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

[_objectManager.router.routeSet addRoute:[RKRoute routeWithName:@"getCardDetailsRoute" pathPattern:@"services/details/:cardNumber" method:RKRequestMethodGET]];

然后我打电话给你

[self.objectManager getObjectsAtPathForRouteNamed:@"getCardDetailsRoute" object:card parameters:@{@"token" : authToken} success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

我知道这是一个很重要的帖子，可能很难理解。感谢您的耐心：D 对我应该做的事感到困惑。

更改REST API实际上不是一种选择。

Answer 1

尝试将期望值设置为@“true”@“false”。我认为这些值在运行动态映射时将是字符串，并且它们将仅在映射期间转换为BOOL，并且目标类型是BOOL。

基于RestKit中JSON响应值的映射
