以下是我在服务器上发布数据的代码.

- (void) callLoginAPI:(NSDictionary *)dictProfile{
    // 1
    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:[dictProfile valueForKey:@"name"],@"username",[dictProfile valueForKey:@"first_name"],@"first_name",[dictProfile valueForKey:@"last_name"],@"last_name",[dictProfile valueForKey:@"email"],@"email",[dictProfile valueForKey:@"birthday"],@"dob",[dictProfile valueForKey:@"gender"],@"gender",[[dictProfile valueForKey:@"location"] valueForKey:@"name"],@"location",[dictProfile valueForKey:@"timezone"],@"timezone",@"",@"language",[NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=large",[dictProfile valueForKey:@"id"]],@"profile_pic_url",@"cover_pic_url",nil];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];

    [manager POST:@"http://10.1.81.35:8000/api/login/" parameters:params success:^(AFHTTPRequestOperation *operation,id responSEObject) {
        NSLog(@"JSON: %@",responSEObject);
    } failure:^(AFHTTPRequestOperation *operation,NSError *error) {
        NSLog(@"Error: %@",error);
    }];
}

并作为回应我得到以下错误

Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request Failed: bad request (400)" UserInfo=0x7c87b6f0 {com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x7cc220e0> { URL: http://10.1.81.35:8000/api/login/ } { status code: 400,headers {

我无法理解为什么会出现这种错误.我的代码中缺少什么？
