当我postObject
在 RestKit 中使用该方法时,日志显示一切正常(见下文)。
但是在服务器上,请求被接收为GET
并且请求正文为空,而不是POST
包含序列化对象的 a。
2013-01-12 14:40:08.860 AppName[3953:c07] I restkit.network:RKHTTPRequestOperation.m:152 POST 'http://urlgoeshere.com'
下面是我用于POST
和 RestKit 初始化的代码。我正在使用 RestKit 0.20.0-pre6。
POST 对象到服务器
// CREATE THE MANAGED OBJECT, AND SAVE IT
RKManagedObjectStore *objectStore = [[RKObjectManager sharedManager] managedObjectStore];
Message *msg = [NSEntityDescription insertNewObjectForEntityForName:@"Message" inManagedObjectContext:objectStore.mainQueueManagedObjectContext];
msg.note = @"This is a sample message.";
msg.dateCreated = [NSDate date];
[objectStore.mainQueueManagedObjectContext save:nil];
// BUILD THE REQUEST MAPPING & REQUEST DESCRIPTOR
RKObjectMapping *requestMapping = [RKObjectMapping requestMapping];
[requestMapping addAttributeMappingsFromDictionary:@{
@"messageId": @"id",
@"dateCreated": @"date_created",
}];
[requestMapping addAttributeMappingsFromArray:@[ @"note" ]];
RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:requestMapping objectClass:[Message class] rootKeyPath:@"message"];
[[RKObjectManager sharedManager] addRequestDescriptor:requestDescriptor];
// SEND POST REQUEST TO SERVER
[[RKObjectManager sharedManager] postObject:msg
path:@"/path/to/messages"
parameters:[NSDictionary dictionaryWithObject:[(AppDelegate*)[[UIApplication sharedApplication] delegate] userId] forKey:@"user_id"]
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSLog(@"success!");
}
failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(@"failure.\n\n%@", [error description]);
}
];
App Delegate 中的 RestKit 初始化
NSURL *baseURL = [NSURL URLWithString:@"http://urlgoeshere.com"];
RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL:baseURL];
// Initialize managed object store
NSManagedObjectModel *managedObjectModel = [NSManagedObjectModel mergedModelFromBundles:nil];
RKManagedObjectStore *managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:managedObjectModel];
objectManager.managedObjectStore = managedObjectStore;
// Setup our object mappings
RKEntityMapping *messageMapping = [RKEntityMapping mappingForEntityForName:@"Message" inManagedObjectStore:managedObjectStore];
messageMapping.identificationAttributes = @[ @"messageId" ];
[messageMapping addAttributeMappingsFromDictionary:@{
@"id": @"messageId",
@"date_created": @"dateCreated",
}];
[messageMapping addAttributeMappingsFromArray:@[ @"note" ]];
[managedObjectStore createPersistentStoreCoordinator];
NSString *storePath = [RKApplicationDataDirectory() stringByAppendingPathComponent:@"DBNameHere.sqlite"];
NSError *error;
NSPersistentStore *persistentStore = [managedObjectStore addSQLitePersistentStoreAtPath:storePath fromSeedDatabaseAtPath:nil withConfiguration:nil options:nil error:&error];
NSAssert(persistentStore, @"Failed to add persistent store with error: %@", error);
// Create the managed object contexts
[managedObjectStore createManagedObjectContexts];
// Configure a managed object cache to ensure we do not create duplicate objects
managedObjectStore.managedObjectCache = [[RKInMemoryManagedObjectCache alloc] initWithManagedObjectContext:managedObjectStore.persistentStoreManagedObjectContext];
