如何使用SpringMVC在Java类中保存Facebook返回的响应数据
我正在尝试保存Facebook回复返回的用户数据。 我正在使用Facebook Javascript。响应是JSon格式的,我想先解析它,然后用java将它保存到我的数据库中如何使用SpringMVC在Java类中保存Facebook返回的响应数据,java,javascript,facebook,spring-mvc,Java,Javascript,Facebook,Spring Mvc,我正在尝试保存Facebook回复返回的用户数据。 我正在使用Facebook Javascript。响应是JSon格式的,我想先解析它,然后用java将它保存到我的数据库中 <script> // This is called with the results from from FB.getLoginStatus(). function statusChangeCallback(response) { console.log('statusChangeCallba

我使用的是SpringMVC方法,完全基于JAVA,不使用任何xml文件。
我已经搜索了很多,但在“if(response.status==='connected'){}”块中没有找到任何解决方案。您需要调用Facebook的另一个API,通过传递用户id和令牌来获取用户的详细信息,在收到数据后,您可以通过Ajax调用自己的控制器,并在需要时保存到DB中
另一个解决方案可以是,您可以在服务器端本身使用“”
