Question

当我在RestKit中使用postObject方法时，日志似乎没什么问题（见下文）。

但是在服务器上，请求收到GET且请求正文为空，而不是POST并且包含序列化对象。

2013-01-12 14:40:08.860 AppName[3953:c07] I restkit.network:RKHTTPRequestOperation.m:152 POST 'http://urlgoeshere.com'

以下是我用于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代理中的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];

你在说什么样的服务器？我怀疑你的服务器正在进行重定向或其他什么。 RestKit使用NSURLConnection来发出请求，所以问题是客户端的极不可能，因为你在日志中看到的内容是直接从NSURLRequest中读取的。

RestKit将对象POST到服务器，但服务器收到空的GET请求
