objective-c - 发送发布请求并将 map 响应发送给对象

Question

我是restKit的新手，有几个问题要问您。一世
无法理解如何使用json / xml将发布请求发送到我的网站
服务，并将收到的回复与我的 class 对应。谁能给
我对此有帮助。我正在使用的代码是这样的:
在我的applicationDelegate中，我正在实例化RKObjectManager
提供基本网址:

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]; 

当帖子发送到/ login时，服务器应发送回有效的json
然后将该json映射到我的User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，不会触发objectLoader方法，
Restkit的理解是它们应该在何时被调用

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

被执行？任何帮助表示赞赏:)

好吧，您甚至没有将数据发送到服务器。几天前，我写了一段代码来解释how to post a NSDictionary (as JSON) to a server using RestKit。
