ios - RestKit 映射错误的对象
<p><p>我正在使用 RestKit，这就是我初始化它并添加路由和描述符的方式:</p>
<pre><code> - (void)initRestClient
{
NSURL *baseURL = ;
self.manager = ;
;
;
.responseDescriptors];
.requestDescriptors];
;
;
// AFHTTPClient *client = .HTTPClient;
;
;
}
- (void)initRoutes
{
RKRoute *bannersRoute = pathPattern:@"Banners?categoryID=:categoryID" method:RKRequestMethodGET];
bannersRoute.shouldEscapePath = YES;
;
RKRoute *branchesRoute = pathPattern:@"Branches?city=:city&type=:type" method:RKRequestMethodGET];
branchesRoute.shouldEscapePath = YES;
;
RKRoute *shortTokenRoute = pathPattern:@"users/login/quick/shortToken?phone=:phone&extraCode=:extraCode" method:RKRequestMethodGET];
shortTokenRoute.shouldEscapePath = YES;
;
RKRoute *longTokenRoute = pathPattern:@"users/login/quick/userDetails?shortToken=:shortToken" method:RKRequestMethodGET];
longTokenRoute.shouldEscapePath = YES;
;
}
- (void)initMappingObjectsAndDiscriptors
{
RKObjectMapping *bannerMapping = ];
];
RKResponseDescriptor *bannerDescriptor = ;
RKObjectMapping *branchesMapping = ];
];
RKResponseDescriptor *branchesDescriptor = ;
RKObjectMapping *shortTokenMapping = ];
];
RKResponseDescriptor *shortTokenDescriptor = ;
RKObjectMapping *longTokenMapping = ];
];
// longTokenMapping.setDefaultValueForMissingAttributes = YES;
// longTokenMapping.setNilForMissingRelationships = YES;
RKResponseDescriptor *longTokenDescriptor = ;
];
}

<p>当我尝试调用 RKShortToken 时，我得到了很好的响应，但是我得到的对象是 RKLongToken:</p>
<pre><code>- (void)quickLoginWithTelephone:(NSString*)telephone extraCode:(NSString *)extraCode completionBlock:(quickLoginExtraCodeCompletionBlock)success
{
NSDictionary *params = @{ @"phone" : telephone, @"extraCode" : extraCode };
[ getObjectsAtPath:@"users/login/quick/shortToken?"
parameters:params
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSLog(@"%@", operation.HTTPRequestOperation.responseString);
NSLog(@"%@", mappingResult.array);
success(YES);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(@"Error occurred.");
}];
}

<p>这里似乎有什么问题？</p>
<p>更新:</p>
<p>我已按照@Wain 告诉我的那样将 <code>pathPattern</code> 添加到描述符中，但现在我遇到了错误。它看起来像这样:</p>
<pre><code>"No mappable object representations were found at the key paths searched."
NSLocalizedFailureReason=The mapping operation was unable to find any nested object representations at the key paths searched: Banners, Branches, BranchTypes, Cities, MenuList
The representation inputted to the mapper was found to contain nested object representations at the following key paths: responseError, shortToken
This likely indicates that you have misconfigured the key paths for your mappings., NSLocalizedDescription=No mappable object representations were found at the key paths searched., keyPath=null}`
</code></pre></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您的所有响应描述符都有 <code>pathPattern:nil</code>，因此 RestKit 无法过滤并将应用所有这些描述符并查看会发生什么。因此，对于所有 JSON，您将获得多个对象，其中仅包含与 JSON 匹配的每个映射的部分。</p>
<p>要解决此问题，请添加路径模式以允许 RestKit 确定哪个响应描述符与您的每个请求匹配。</p></p>
