arouter拦截器内路由跳转--postcard.setDestination

目前的方法是在写arouter build目标的时候传入一个回调监听方法，里面可以在路由被拦截的时候做出一些回应，然后拦截器里只是决定是否拦截，想看看有没有可以在拦截器里直接处理一些问题的方法 ，实在没有也可以把一些处理完了再返回一些flag

照理来说是有post.setPath是可以改变目标页面的
改之前的postcard

Postcard
{uri=/v3/ui/X6ApprovalClientActivity,
tag=null, 
mBundle=Bundle[{NTeRQWvye18AkPd6G=/v3/ui/X6ApprovalClientActivity}],
 flags=0, 
 timeout=300, 
 provider=null, 
 greenChannel=false, 
 optionsCompat=null, 
 enterAnim=-1, 
 exitAnim=-1}

实际上已经把path和extra里都改了但是都没有生效跳转，打印了先后的postcard之后改了一下distination才成功
借鉴一下吧

                        Log.i("qqhh", "拦截器改之前的目标页面："+postcard.getPath());
                        Log.i("qqhh", "拦截器改过的目标页面postcard："+postcard);
                        Log.i("qqhh", "拦截器改之前的目标页面："+postcard.getUri());
                        Log.i("qqhh", "拦截器Extras："+postcard.getExtras());
                        postcard.setExtra(5);
                        postcard.setPath("/kuozhi/qq/toBeMTeacherActivity");
                        Uri uri = Uri.parse("/v3/ui/mqWebviewActivity");
                        postcard.setUri(uri);
                        Bundle bundle = new Bundle();  //得到bundle对象
                        bundle.putString("NTeRQWvye18AkPd6G", "/kuozhi/qq/toBeMTeacherActivity");  //key-"sff",通过key得到value-"value值"(String型)
                        postcard.with(bundle);
                        postcard.withInt("courseId",courseId);
                        postcard.setDestination(toBeMTeacherActivity.class);
//                        Bundle bd=[{"NTeRQWvye18AkPd6G":"/v3/ui/X6ApprovalClientActivity"}];
//                        Bundle[{NTeRQWvye18AkPd6G=/v3/ui/X6ApprovalClientActivity}]


                        Log.i("qqhh", "拦截器改过的目标页面path："+postcard.getPath());
                        Log.i("qqhh", "拦截器改过的目标页面postcard："+postcard);
                        Log.i("qqhh", "拦截器改之前的目标页面uri："+postcard.getUri());
                        Log.i("qqhh", "拦截器Extras："+postcard.getExtras());
                        Log.i("qqhh", "拦截器courseId："+postcard.getExtras().getInt("courseId"));

点击按钮后是模块里的firstActivity
转activity之后，看看拦截器里是执行navigation的时候拦截，判断name和age是否为空
之后为空的时候拦截，不为空跳转
arouter提供了拦截器接口和@Interceptor注解，拦截方法在process里
一个用于组件化改造的框架，支持模块间的路由通信和解耦，拦截跳转

记录启动日志的拦截器，之后是在arouter传入参数

startActivityForResult

在第一个activity里设置安装体制屯result里接收请求代码，响应代码和和intent data，里面处理一下请求代码是123的写法
之后在跳转的navigation里带请求代码
在第二个页面使用setresult方法可以带参返回第一个页面

拦截的方法是在process里，可以设置一下运行exception

postcard.getExtras().getInt(“age”);
postcard.getExtras().getString(“name”);

额外关注一下afterInit方法，返回了拦截服务器的单实例对象
