ios - RESTKit:删除带有主体参数的对象

Question

RESTKit 0.20.x

我需要发送以下DELETE请求:

网址:http://rest.domain.com/invite

正文:{@“inviteId”:“1234”}

在尝试建立该请求时，以下是我正在使用的代码:

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
self.objectManager = [self getObjectManager];
self.objectManager.managedObjectStore = appDelegate.managedObjectStore;

RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[InviteDelete class]];


RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[mapping inverseMapping] objectClass:[NSMutableDictionary class] rootKeyPath:nil method:RKRequestMethodDELETE];

NSIndexSet *statusCodeSet = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping
                                                                                        method:RKRequestMethodAny
                                                                                   pathPattern:@"/invites"
                                                                                       keyPath:nil
                                                                                   statusCodes:statusCodeSet];

self.objectManager.requestSerializationMIMEType = RKMIMETypeJSON;
[self.objectManager addRequestDescriptor:requestDescriptor];
[self.objectManager addResponseDescriptor:responseDescriptor];

[self.objectManager.HTTPClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];


InviteDelete *objectToDelete = [[InviteDelete alloc]init];
objectToDelete.inviteId = [NSNumber numberWithInt:294];

[self.objectManager deleteObject:objectToDelete path:@"/invites" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

} failure:^(RKObjectRequestOperation *operation, NSError *error) {
}];

Charles Log显示以下请求正在发送(RAW):

DELETE /invites HTTP/1.1
Host: rest.domain.com
Accept: application/json
Connection: keep-alive
Cookie: connect.sid=PLv05FHG8Al7A84x84mMd.mjlxE3ff3Map
User-Agent: App/1.0 (iPhone Simulator; iOS 7.1; Scale/2.00)
Accept-Language: en;q=1, fr;q=0.9, de;q=0.8, zh-Hans;q=0.7, zh-Hant;q=0.6, ja;q=0.5
Content-Length: 0
Accept-Encoding: gzip, deflate

我知道将URL嵌入时创建DELETE会更容易，我可以在其中简单地将parameters添加到objectManager中。我希望我有这个选择!我必须创建一个带有DELETE的正文参数的请求。

要求:如何创建一个简单的JSON DELETE请求，该请求中包含以下内容？

{@“inviteId”:“1234”}

可选:很好，RESTKit也可以在成功后删除本地对象。

您的请求描述符是错误的，因为您使用了objectClass:[NSMutableDictionary class]，因此仅在您尝试删除NSMutableDictionary实例时才适用。您应该使用:

... objectClass:[InviteDelete class] ...

RestKit没有内置的方式来理解响应并自动删除源对象，因此您需要验证响应内容，然后执行删除并将其保存在success回调块中。
