afnetworking post to local host使用curl工作

Question

我正在使用afnetworking 2.0来发帖。使用谷歌应用邮递员，我能够发布很好，但是当使用afnetworking我得到以下错误：

Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo=0x10d5f6270 {NSUnderlyingError=0x10ed45a80 "unsupported URL", NSErrorFailingURLStringKey=localhost:5000/api/createNewTenant, NSErrorFailingURLKey=localhost:5000/api/createNewTenant, NSLocalizedDescription=unsupported URL}

AFNetworking不支持localhost吗？这是我的afnetworking代码：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    NSDictionary *parameters = @{@"email" : self.emailField.text,
                                 @"message" : self.message.text };
    [manager POST:@"localhost:5000/api/createNewTenant" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
