如何使用 restkit 发帖

Question

我正在使用 restkit 构建一个应用程序来与我的网络服务通信。首先，我对此很陌生。我需要做的是将用户名和密码发布到我的 web 服务，以便 url 看起来像这样。

http://urllinkcompany.com/en/webservice/company-user/login/apikey/key12345678?email=test@test.be&pwd=testtest

当我发布此内容时，我会返回一个 json。这个 json 包含一个状态码。 status = 200 --> OK Status = 404 --> NOT ok

现在我尝试发布一些内容并 NSLog 这个状态代码。

- (IBAction)login:(id)sender {

    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Person class]];
    [mapping addAttributeMappingsFromDictionary:@{
     @"data.user.cu_email":     @"cu_email",

     }];


    RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping pathPattern:nil keyPath:nil statusCodes:nil];

    NSString *baseUrl = @"http://urllinkcompany.com/en/webservice/company-user/login/apikey/key12345678?";
    NSString *strUrl = [NSString stringWithFormat:@"%@email=%@&pwd=%@",baseUrl,_txtLogin.text,_txtPass.text];
    NSURL *url = [NSURL URLWithString:strUrl];
    NSLog(@"url is: %@",strUrl);
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    RKObjectRequestOperation *operation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[responseDescriptor]];
    [operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
         NSLog(@"data result is %@", [result valueForKeyPath:@"data.status"]);
    } failure:nil];

}

但是我收到了这个错误。

 E restkit.network:RKObjectRequestOperation.m:285 Object request failed: Underlying HTTP request operation failed with error: Error Domain=NSURLErrorDomain Code=-1000 "bad URL" UserInfo=0x1ed57c50 {NSUnderlyingError=0x20161e70 "bad URL", NSLocalizedDescription=bad URL}

有人可以帮我解决这个问题吗？

亲切的问候

编辑： 这是一个没有 RKClient 的版本

RKObjectManager* objectManager = [RKObjectManager objectManagerWithBaseURL:[NSURL URLWithString:@"http://urllinkcompany.com/"]];

RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Person class]];
[mapping addAttributeMappingsFromDictionary:@{
 @"data.user.cu_email":     @"cu_email",
 }];

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:_txtLogin.text, @"email", _txtPass.text, @"pwd", nil];

[objectManager loadObjectsAtResourcePath:@"en/webservice/company-user/login/apikey/key12345678" delegate:self block:^(RKObjectLoader* loader) {
    loader.objectMapping = mapping;
    loader.method = RKRequestMethodPOST;
    loader.params = params;
}];

并实现这两个 RKObjectLoaderDelegate 方法：

- (void)objectLoader:(RKObjectLoader *)objectLoader didLoadObjects:(NSArray *)objects

- (void)objectLoader:(RKObjectLoader *)objectLoader didFailWithError:(NSError *)error
