Question

我是RestKit的新手，我正在尝试使用POST请求登录我的系统。我正在使用RestKit版本0.20.3，这就是我的做法：

- (IBAction)login:(id)sender {
    NSString *email = [self.emailTextField text];
    NSString *password = [self.passwordTextField text];

    NSURL *url = [[NSURL alloc] initWithString:@"http://myhost.com/api.php"];
    RKObjectManager *manager = [RKObjectManager managerWithBaseURL:url];
    NSDictionary *tmp = @{@"rquest":@"user",
                          @"tag":@"login",
                          @"email":email,
                          @"password":password};
    [manager postObject:tmp path:@"" parameters:nil
                success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
                    NSDictionary *result = [mappingResult dictionary];
                    if([[result objectForKey:@"success"] isEqualToNumber:[NSNumber numberWithInt:1]]){
                        NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
                        [def setBool:YES forKey:@"isLoggedIn"];
                        // set user details...
                        [self.navigationController popToRootViewControllerAnimated:YES];
                    }
                }
                failure:^(RKObjectRequestOperation *operation, NSError *error) {
                    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                    message:[error localizedDescription]
                                                                   delegate:nil
                                                          cancelButtonTitle:@"OK"
                                                          otherButtonTitles:nil];
                    [alert show];
                    NSLog(@"Hit error: %@", error);
                }];
}

如您所见，由于我不需要将响应映射到对象，因此我尝试使用NSDictionary访问响应数据。我不确定这是不是问题，但是当我尝试运行上面的代码时，我收到错误：

013-10-06 11:24:51.897 Eateries[1182:454b] E restkit.network:RKResponseMapperOperation.m:304 Failed to parse response data: Loaded an unprocessable response (404) with content type 'application/json'

我真的很困惑，因为我真的不知道我在这里做错了什么。如果您有任何建议，请告诉我。谢谢。

P.s：我为了个人目的更改了主机的名称，但是当我尝试从其他平台测试时，我的服务器确实对该请求做出了响应。

您使用的是错误的API。

postObject:...用于发布要映射的对象，这意味着object参数（如果不是nil）将用作映射响应的目标。

如果您不想映射响应，只需使用基础AFHTTPClient执行普通POST请求。

[[RKObjectManager sharedManager].HTTPClient postPath:@"" parameters:tmp success:^(AFHTTPRequestOperation *operation, id responseObject) {
    // ...
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    // ...
}

使用带有RestKit的POST登录会返回404错误
