我正在尝试扩展现有应用以存储特定对象服务器端的用户收藏夹。
该应用正在使用RestKit~＆gt; 0.26.0，它使用响应描述符设置了许多GET调用。但是，当我为POST / DELETE调用的请求描述符进行逆映射时，它似乎无法导致生成任何请求体。
请求描述符设置代码：
// Code User Favorites Mapping
RKEntityMapping *codeFavoritesMapping = [RKEntityMapping mappingForEntityForName:@"Code" inManagedObjectStore:objectStore];
[codeFavoritesMapping setIdentificationAttributes:@[@"scheme", @"code"]];
[codeFavoritesMapping addAttributeMappingsFromArray:@[ @"cuid", @"code", @"scheme" ]];
[codeFavoritesMapping addAttributeMappingsFromDictionary:@{ @"shortdesc" : @"text" }];
// POST/DELETE
[[RKObjectManager sharedManager] addRequestDescriptor:[RKRequestDescriptor requestDescriptorWithMapping:[codeFavoritesMapping inverseMapping]
objectClass:[Code class]
rootKeyPath:nil
method:(RKRequestMethodPOST | RKRequestMethodDELETE)]];
// GET
[[RKObjectManager sharedManager] addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:codeFavoritesMapping
method:RKRequestMethodGET
pathPattern:kRestKitEndpointCodeFavorites
keyPath:API_WRAPER_KEYPATH
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];
请注意，上面设置的GET按预期运行。
以下是POST / DELETE调用本身：
if (isFavorite) { // Removing from favorite list
...
// Delete favorite server side
[[RKObjectManager sharedManager] deleteObject:_code path:kRestKitEndpointCodeFavorites parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSLog(@"Deleted code: %@", _code.code);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(@"Failed to delete code: %@", _code.code);
}];
} else { // Adding to favorite list
...
// Add favorite server side
[[RKObjectManager sharedManager] postObject:_code path:kRestKitEndpointCodeFavorites parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSLog(@"Added code: %@", _code.code);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(@"Failed to add code: %@", _code.code);
}];
}
根据我的理解，这应该导致POST / DELETE调用发送一个类似的请求体：
{"code":"101","scheme":"scheme1","cuid":"123456789","shortdesc":"Basic code sample"}
然而，服务器和RestKit日志显示没有任何内容被发送。也许我错过了一些基本的东西？
让我知道您认为可能是什么问题，或者您是否需要进一步的信息/澄清。谢谢你的时间！

编辑：回应Wain的问题
我已经检查了服务器收到了什么，但它只是一个空的请求主体发送。我已经尝试在两个POST / DELETE调用的参数部分中传递对象的字典，手动编码。
对POST参数进行手动编码会按预期发送，并且生成的请求正文完全符合要求。但是，手动编码DELETE调用的结果会导致手动编码参数成为url查询字符串的一部分;即https://mobile-api.myapp.com:8000/v2/codes?code=101&scheme=scheme1&cuid=123456789&shortdesc=Basic code sample
RestKit MIME类型设置：
RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:API_HOST_NAME]];
[RKObjectManager setSharedManager:objectManager];
[objectManager setRequestSerializationMIMEType:RKMIMETypeJSON];
[objectManager setAcceptHeaderWithMIMEType:RKMIMETypeJSON];
