Objective c 向对象发送post请求和映射响应

我是restKit的新手，我有几个问题要问你。我 无法理解如何使用json/xml将Post请求发送到我的web 服务并将传入的回复映射到我的类。有人能给我吗 请帮我一个忙。我使用的代码如下： 在ApplicationLegate中，我正在实例化RKObjectManager 提供基本URL：

RKObjectManager* manager = [RKObjectManager objectManagerWithBaseURL:@"https://example.com/services/"]; 

   // Request params in Dictionary 
    NSArray *objects = [NSArray arrayWithObjects: email, password, 
nil]; 
    NSArray *keys = [NSArray arrayWithObjects:@"username", 
@"password", nil]; 
    NSDictionary *params = [NSDictionary dictionaryWithObjects:objects 
forKeys:keys]; 
    NSLog(@"Manager: %@", [RKObjectManager 
sharedManager].description); 
    // User object Mapping 
    RKObjectMapping* userMapping = [RKObjectMapping mappingForClass: 
[User class]]; 
    [userMapping mapKeyPath:@"userName" toAttribute:@"userName"]; 
    [userMapping mapKeyPath:@"lastName" toAttribute:@"lastName"]; 
    [userMapping mapKeyPath:@"active" toAttribute:@"active"]; 
    [[RKObjectManager sharedManager].mappingProvider 
setMapping:userMapping forKeyPath:@"user"]; 
    [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/ 
login" delegate:self]; 

当post发送到/登录时，服务器应发送回有效的json 然后将该json映射到我的用户类

- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects: 
(NSArray*)objects { 
    RKLogInfo(@"Load collection of Articles: %@", objects); 
} 

- (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError: 
(NSError *)error 
{ 
    NSLog(@"Objecy Loader failed: %@", error); 
} 

- (void)request:(RKRequest *)request didFailLoadWithError:(NSError 
*)error 
{ 
    NSLog(@"Request failed"); 
} 

- (void)request:(RKRequest*)request didLoadResponse: 
(RKResponse*)response { 
    if ([request isGET]) { 
        // Handling GET /foo.xml 
        if ([response isOK]) { 
            // Success! Let's take a look at the data 
            NSLog(@"Retrieved XML: %@", [response bodyAsString]); 
        } 
    } else if ([request isPOST]) { 
        // Handling POST /other.json 
        if ([response isXML]) { 
         ///NSLog(@"Seng a JSON request:! \n %@", [request 
HTTPBodyString]); 
            NSLog(@"Got a responce! \n %@", [response bodyAsString]); 
        } 
    } else if ([request isDELETE]) { 
        // Handling DELETE /missing_resource.txt 
        if ([response isNotFound]) { 
            NSLog(@"The resource path '%@' was not found.", [request 
resourcePath]); 
        } 
    } 
} 

当我执行它时，objectLoader方法不会被触发，我的 对restkit的理解是，他们应该在

[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/login" 
delegate:self];

被处决了？非常感谢您的帮助：）

您是否记得使用将restkit的委托设置为该用户类（或者在您捕获委托的任何位置）

另外，我认为添加映射的较新方法是

[sharedManager.mappingProvider addObjectMapping:userMapping];
[sharedManager.mappingProvider setMapping:userMapping forKeyPath:@"/somepath"];

[sharedManager.mappingProvider setSerializationMapping:[userMapping inverseMapping] forClass:[User class]];
 // Must set the router up to handle posts
 [sharedManager.router routeClass:[User class] toResourcePath:@"/api/users" forMethod:RKRequestMethodPOST];

再次编辑：并使用如下加载程序创建一篇文章。可能是因为你的所作所为而杀人，但看一眼也无妨

RKObjectLoader* loader = [RKObjectLoader loaderWithResourcePath:url objectManager:self.objectManager delegate:self.currentDelegate];
    loader.method = RKRequestMethodPOST;
    loader.sourceObject = self;
    loader.targetObject = self;  

    loader.serializationMIMEType = self.objectManager.serializationMIMEType;
    loader.serializationMapping = [self.objectManager.mappingProvider serializationMappingForClass:self.mappingClass];

    loader.objectMapping = [self.objectManager.mappingProvider objectMappingForClass:self.mappingClass];

    [loader send]; //<<the actual post

RKObjectLoader*loader=[RKObjectLoader loaderWithResourcePath:url objectManager:self.objectManager委托：self.currentDelegate]；
loader.method=RKRequestMethodPOST；
loader.sourceObject=self；
loader.targetObject=self；
loader.serializationMIMEType=self.objectManager.serializationMIMEType；
loader.serializationMapping=[self.objectManager.mappingProvider serializationMappingForClass:self.mappingClass]；
loader.objectMapping=[self.objectManager.mappingProvider objectMappingForClass:self.mappingClass]；
[加载器发送]// 嗯，您甚至不向服务器发送数据。几天前，我写了一段解释
 是的，具有这些方法的类正在实现RKObjectLoaderDelegate
[sharedManager.mappingProvider addObjectMapping:userMapping];
[sharedManager.mappingProvider setMapping:userMapping forKeyPath:@"/somepath"];

[sharedManager.mappingProvider setSerializationMapping:[userMapping inverseMapping] forClass:[User class]];
 // Must set the router up to handle posts
 [sharedManager.router routeClass:[User class] toResourcePath:@"/api/users" forMethod:RKRequestMethodPOST];

RKObjectLoader* loader = [RKObjectLoader loaderWithResourcePath:url objectManager:self.objectManager delegate:self.currentDelegate];
    loader.method = RKRequestMethodPOST;
    loader.sourceObject = self;
    loader.targetObject = self;  

    loader.serializationMIMEType = self.objectManager.serializationMIMEType;
    loader.serializationMapping = [self.objectManager.mappingProvider serializationMappingForClass:self.mappingClass];

    loader.objectMapping = [self.objectManager.mappingProvider objectMappingForClass:self.mappingClass];

    [loader send]; //<<the actual post
