Restkit Post 总是进入失败部分

Question

我有一个 restkit 函数，我调用一个 web 服务来检查我的登录凭据。在这次通话中，我将我的电子邮件和密码作为参数。在这里你可以看到代码。

RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://****.com/nl/webservice/"]];


NSDictionary *dictionary = [[NSDictionary alloc]initWithObjectsAndKeys:_txtLogin.text,@"email",_txtPass.text,@"pwd", nil];
      NSLog(@"till here");
NSMutableURLRequest *request = [manager requestWithObject:nil method:RKRequestMethodPOST path:@"company-user/login/apikey/key*****?" parameters:dictionary];
      NSLog(@"till here2");
RKObjectRequestOperation *operation = [manager objectRequestOperationWithRequest:request success:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
    NSLog(@"till here3");
    NSLog(@"Loading mapping result: %@", result);
}failure:^(RKObjectRequestOperation *operation, NSError *error){
    //Failure
    NSLog(@"error is:%@ ",error);
    NSLog(@"FAILUREE!");
}];

      NSLog(@"till here4");
[operation start];
      NSLog(@"till here5");

但由于某种原因，我进入了失败的部分。它首先给了我一个状态 200，然后是一个错误。你可以在这里查看我的日志。

有人可以帮我吗？

亲切的问候

Answer 1

如果您希望为响应调用 Web 服务执行对象映射，则必须提供响应描述符。请查看https://github.com/RestKit/RestKit/wiki/Object-Mapping 以获取说明和示例。

Answer 2

我也在问同样的问题，“难道我不能只读取 json 文件吗？没有对象映射？”我发现的解决方案是 RestKit 0.20 使用 AFNetworking .因此，如果您需要在没有映射的情况下发出请求，请执行下一步。

[AFNetworkActivityIndicatorManager sharedManager].enabled = YES;

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://****.com/nl/webservice/"]];
NSDictionary *params     = [NSDictionary dictionaryWithObjectsAndKeys:
                            _txtLogin.text, @"email",
                            _txtPass.text,  @"pwd",
                            nil];
[httpClient postPath:@"company-user/login/apikey/key*****?" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSData *jsonData = [operation.responseString dataUsingEncoding:NSUTF8StringEncoding];
    NSError *error = nil;

    NSDictionary *jsonDict =    [NSJSONSerialization JSONObjectWithData: jsonData
                                                                options: NSJSONReadingMutableContainers
                                                                  error: &error];
    NSLog(@"%@", jsonDict);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"[HTTPClient Error]: %@", error.localizedDescription);
}];
