Question

RESTKit 0.20.x

我需要发送以下DELETE请求：

网址：http://rest.domain.com/invite

body：{@＆＃34; inviteId＆＃34; ：＆＃34; 1234＆＃34; }

在尝试构建该请求时，下面是我正在使用的代码：

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
self.objectManager = [self getObjectManager];
self.objectManager.managedObjectStore = appDelegate.managedObjectStore;

RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[InviteDelete class]];


RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[mapping inverseMapping] objectClass:[NSMutableDictionary class] rootKeyPath:nil method:RKRequestMethodDELETE];

NSIndexSet *statusCodeSet = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping
                                                                                        method:RKRequestMethodAny
                                                                                   pathPattern:@"/invites"
                                                                                       keyPath:nil
                                                                                   statusCodes:statusCodeSet];

self.objectManager.requestSerializationMIMEType = RKMIMETypeJSON;
[self.objectManager addRequestDescriptor:requestDescriptor];
[self.objectManager addResponseDescriptor:responseDescriptor];

[self.objectManager.HTTPClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];


InviteDelete *objectToDelete = [[InviteDelete alloc]init];
objectToDelete.inviteId = [NSNumber numberWithInt:294];

[self.objectManager deleteObject:objectToDelete path:@"/invites" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

} failure:^(RKObjectRequestOperation *operation, NSError *error) {
}];

Charles Log显示以下请求被发送（RAW）：

DELETE /invites HTTP/1.1
Host: rest.domain.com
Accept: application/json
Connection: keep-alive
Cookie: connect.sid=PLv05FHG8Al7A84x84mMd.mjlxE3ff3Map
User-Agent: App/1.0 (iPhone Simulator; iOS 7.1; Scale/2.00)
Accept-Language: en;q=1, fr;q=0.9, de;q=0.8, zh-Hans;q=0.7, zh-Hant;q=0.6, ja;q=0.5
Content-Length: 0
Accept-Encoding: gzip, deflate

我知道在嵌入网址时创建DELETE会更容易，我只需将parameters添加到objectManager。我希望我有这个选择！我必须使用DELETE的body参数创建一个请求。

要求：如何创建一个在正文中包含以下内容的简单JSON DELETE请求？

{@＆＃34; inviteId＆＃34; ：＆＃34; 1234＆＃34; }

可选：RESTKit也可以在成功时删除本地对象。

Answer 1

您的请求描述符是错误的，因为您使用objectClass:[NSMutableDictionary class]因此仅在您尝试删除NSMutableDictionary实例时才适用。你应该使用：

... objectClass:[InviteDelete class] ...

RestKit没有内置的方法来理解响应并自动删除源对象，因此您需要验证响应内容，然后在success回调块中执行并保存删除。

Answer 2

您无法通过对象映射获取删除请求的正文。 Rest API设计支持DELETE body HTTP 1.1标准

也是如此

Rest工具包不支持对象映射，但它肯定允许您创建自定义请求和操作

NSDictionary *params = YOUR_JSON_BODY

NSMutableURLRequest *request = [self requestWithPathForRouteNamed:path
                                                           object:objectToDelete
                                                       parameters:nil];
[request setHTTPBody:[NSJSONSerialization dataWithJSONObject:params options:NSJSONReadingMutableLeaves error:nil]];
[request setHTTPMethod:@"DELETE"];
RKObjectRequestOperation *operation = [self objectRequestOperationWithRequest:request success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult)
{
   if (success) ...
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    if (failure) failure(error);
}];

[self enqueueObjectRequestOperation:operation];

RESTKit：使用Body参数删除对象
