ios - 如何将PUT请求添加到RestKit +核心数据？

在RKGist示例应用程序之后，我设法通过RestKit使我的API与Core Data同步。

这仅适用于具有关联的一个模型。我正在尝试添加其他路线，但无法正常工作。

AppDelegate.m

- (void)setupRestKit
{
    // ...
    RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[JGMappingProvider personMapping]
                                                                                            method:RKRequestMethodGET
                                                                                       pathPattern:@"people"
                                                                                           keyPath:@"response"
                                                                                       statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

    [objectManager addResponseDescriptor:responseDescriptor];



    responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[JGMappingProvider companyMapping]
                                                                      method:RKRequestMethodGET
                                                                 pathPattern:@"companies"
                                                                     keyPath:@"response"
                                                                 statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

    [objectManager addResponseDescriptor:responseDescriptor];


    // add some routes
    [[RKObjectManager sharedManager].router.routeSet addRoute:[RKRoute routeWithName:@"approve_company" pathPattern:@"companies/:companyId/approve" method:RKRequestMethodPUT]];

    ...
}

JGMappingProvider.m

+ (RKMapping *)companyMapping
{
    RKEntityMapping *mapping = [RKEntityMapping mappingForEntityForName:@"Company"
                                                          inManagedObjectStore:[[RKObjectManager sharedManager] managedObjectStore]];

    [mapping addAttributeMappingsFromDictionary:@{
                                                         @"id":             @"companyId",
                                                         @"name":           @"name",
                                                         @"looking_for":    @"lookingFor",
                                                         @"location":       @"location",
                                                         @"updated_at":     @"updatedAt",
                                                         @"created_at":     @"createdAt"}];

    mapping.identificationAttributes = @[ @"companyId" ];

    [mapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"person" toKeyPath:@"person" withMapping:[self personMapping]]];

    return mapping;

}

+ (RKMapping *)personMapping
{
    RKEntityMapping *mapping = [RKEntityMapping mappingForEntityForName:@"Person"
                                                         inManagedObjectStore:[[RKObjectManager sharedManager] managedObjectStore]];


    [mapping addAttributeMappingsFromDictionary:@{
                                                        @"name":           @"name",
                                                        @"nickname":       @"nickname",
                                                        @"id":             @"personId",
                                                        @"email":          @"email"}];

    mapping.identificationAttributes = @[ @"personId" ];

    return mapping;
}

@end

这一切都很好。但是，当我尝试添加一些额外的路线时…

ViewController.m

- (void)approve
{
    NSMutableURLRequest *request = [[RKObjectManager sharedManager] requestWithPathForRouteNamed:@"approve_company" object:_company parameters:nil];
    [self sendRequestWithSharedManager:request];
}

- (void)reject
{
    NSMutableURLRequest *request = [[RKObjectManager sharedManager] requestWithPathForRouteNamed:@"reject_company" object:_company parameters:nil];
    [self sendRequestWithSharedManager:request];
}

- (void)sendRequestWithSharedManager:(NSMutableURLRequest *)request {
    RKObjectRequestOperation* operation = [[RKObjectManager sharedManager] objectRequestOperationWithRequest:(NSURLRequest *)request success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
        NSLog(@"success!");
    } failure:^(RKObjectRequestOperation *operation, NSError *error) {
        NSLog(@"%@", [error description]);
    }];


    operation.targetObject = nil; // this was suggested in a tutorial, has no affect

    NSLog(@"Requested %@", [operation.HTTPRequestOperation.request.URL description]); // this is the correct URL, all the time

    [[RKObjectManager sharedManager] enqueueObjectRequestOperation:operation];
}

大多数情况下，它会失败。具体来说，前两个请求似乎失败了—根本没有打我的服务器(我在服务器端有一些断点要调试)，但是在第三个请求上它可以正常工作。

我感到困惑-如果它第三次正常工作，那么大概是正确的设置了吗？

这些是日志-有点混乱，我真的不知道我在寻找什么。

啊-原来是/正在/打我的服务器，日志是错误的。小学生错误-对此感到抱歉。

我仍然有我的响应描述符设置不正确的问题-我可以在这方面获得帮助吗？

[RKResponseDescriptor responseDescriptorWithMapping:[JGMappingProvider companyMapping]
                                             method:RKRequestMethodPUT
                                        pathPattern:@"companies/:companyId/approve"
                                            keyPath:@"response"
                                        statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

我似乎无法使pathPattern匹配-理想情况下，我将具有一个匹配company /:companyId / approve＆companies /:companyId / reject的通配符，但我看不到如何在文档中进行匹配。

抱歉的愚蠢问题!

编辑:完成!我在用responseDescriptorWithMapping: method: pathPattern: keyPath: statusCodes:-使用(已弃用？)responseDescriptorWithMapping: pathPattern: keyPath: statusCodes:

最佳答案

首先，您确定没有击中服务器-根据您的日志，它似乎可以到达服务器:

'http://localhost:1313/api/1/companies/19/approve' (200 OK / 0 objects) [request=1.0492s mapping=0.0000s total=1.0514s]

您的第二个RKResponseDescriptor(公司专用的RKResponseDescriptor)似乎设置不正确，这似乎是一个问题。

您是否可以尝试不重用局部变量responseDescriptor来创建和传递第二个RKResponseDescriptor。
