我正在尝试使用 RestKit 0.20.0 登录到运行 Devise 的 RoR 后端。我正在尝试使用以下参数实现请求：
Parameters: {"password"=>"[FILTERED]", "email"=>"email@mail.com"}
但在服务器上实际收到的是以下内容：
Parameters: {"password"=>"[FILTERED]", "email"=>"email@mail.com", "session"=>{"password"=>"[FILTERED]", "email"=>"email@mail.com"}}
这个会话参数来自哪里，我不知道。执行 GET 时不添加，仅在执行 POST 时添加。登录通过，但响应完全错误。通过使用正确的参数列表，可以给出正确的响应。下面是发送请求的代码。关于这个会话参数来自哪里的任何想法？
- (void)loginWithblock:(void (^)(bool))block
{
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:_username, @"email", _password, @"password", nil];
NSString *url = [[MBMSettingsHelper sharedSettingsHelper] authenticationURL];
[[RKObjectManager sharedManager] postObject:nil path:url parameters:params
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
block(YES);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
block(NO);
}];
}
在我的 appdelegate 中，我有以下映射器：
// Mappers for authentication
RKObjectMapping *requestMappingForAuthenticate = [RKObjectMapping requestMapping];
[requestMappingForAuthenticate addAttributeMappingsFromDictionary:@{
@"username" : @"email",
@"password": @"password"
}];
RKRequestDescriptor *requestDescriptorForAuthenticate = [RKRequestDescriptor requestDescriptorWithMapping:requestMappingForAuthenticate objectClass:[MBMUserLoginRequest class] rootKeyPath:nil];
RKObjectMapping *responseMappingForAuthenticate = [RKObjectMapping requestMapping];
[responseMappingForAuthenticate addAttributeMappingsFromDictionary:@{
@"success": @"success",
@"auth_token": @"token",
@"email": @"username",
@"id": @"userId"}];
RKResponseDescriptor *responseDescriptorForAuthenticate = [RKResponseDescriptor responseDescriptorWithMapping:responseMappingForAuthenticate pathPattern:nil keyPath:nil statusCodes:nil];
[objectManager addResponseDescriptor:responseDescriptorForAuthenticate];
[objectManager addRequestDescriptor:requestDescriptorForAuthenticate];
编辑：
RestKit 日志发布在下面。看起来登录后，映射器开始使用完全不同的模型（在这种情况下为船）映射登录响应？

编辑 2：当我删除我的其他 RKResponseDescriptors 时，一切正常。所以问题是在映射发生时以某种方式选择了错误的 RKResponseDescriptor ...
