發送帖子請求和地圖回覆對象

Question

我是新來restKit，我有幾個問題給你。我 不知道如何發送Post請求使用json/xml到我的網絡 服務和映射傳入的答覆與我的班。任何一個可以給我 幫助。我使用的代碼是這樣的： 在我applicationDelegate我實例化RKObjectManager 提供基本網址：

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]; 

在一個職位發送到/登錄服務器應該發回一個有效的JSON 然後映射該JSON我的用戶類。

- (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]); 
     } 
    } 
} 

當我執行它的objectLoader方法不會被觸發，我restkit的 理解是，當

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

執行他們應該叫什麼？任何幫助表示讚賞:)

你沒忘了與

@interface User : NSObject<RKObjectLoaderDelegate>{ 
} 

你可能沒有，但它值得一提的櫃面設置委託restkit到用戶類（或任何你有被抓的代表） ：P

並且在這一行傳遞的自我就是那個類？

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

還我想補充的映射較新的方式是與建立上崗再次

[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]; 

編輯：創建和使用這樣的裝載機後。可能全部都是因爲你的行爲而殺了，但是不能傷害你去看看

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

那麼，你甚至不會將你的數據發送到服務器。幾天前，我寫了一段代碼解釋how to post a NSDictionary (as JSON) to a server using RestKit。
