ios – 错误域= com.alamofire.error.serialization.response代码= -1011“请求失败：错误请求(400)

概述我正在使用AFnetworking库在服务器上发布数据. 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 valueForKe 我正在使用AFnetworking库在服务器上发布数据.

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

我无法理解为什么会出现这种错误.我的代码中缺少什么？

解决方法 错误说明了一切：你从服务器得到一个 400 response,这意味着你发送的内容要么格式不正确,要么服务器无法理解它. 总结
