服务总线拦截器

需求：
1、新环境下，业务接口要走服务总线，所有的接口地址都有变化；
2、不用每个接口都修改，通过拦截器统一实现（根据原有的接口路径，指向服务总线的新接口地址；）

1、Retrofit2 使用自定义的总线拦截器：

 @Override
 public void okHttpClient(OkHttpClient.Builder builder) {
     builder.addInterceptor(new ServiceBusInterceptor());
 }

2、ServiceBusInterceptor.java

public class ServiceBusInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        HttpUrl oldUrl = request.url();
        LegoLog.w("拦截器：旧地址：" + oldUrl.toString());
        //通过旧地址查询到新地址：

        Request.Builder builder1 = request.newBuilder();
        String resourceId = getResourceId(oldUrl.toString());
        builder1.addHeader("resId", resourceId);//资源id
        builder1.addHeader("userCredential", URLEncoder.encode(MainApplication.getUserCredential_json(), "UTF-8"));//用户凭证
        builder1.addHeader("appCredential", URLEncoder.encode(MainApplication.getAppCredential_json(), "UTF-8"));//应用凭证

        String newUrl = getUrl(resourceId);
        LegoLog.w("拦截器：新地址：" + newUrl);
        if (TextUtils.isEmpty(newUrl)) {
            ToastUtil.showCommonToast("未找到对应的服务信息", Toast.LENGTH_LONG);
        } else {
            builder1.url(newUrl);
        }
        
        return chain.proceed(builder1.build());
    }

    
    public String getResourceId(String url) {
        for (Map.Entry entry : Constant.RESOURCE_MAP.entrySet()) {
            String url_suffix = entry.getKey();
            String resourceId = entry.getValue();
            if (url.endsWith(url_suffix)) {
                return resourceId;
            }
        }
        LegoLog.w("接口：" + url + "未找到对应的resourceId");
        return "";
    }

    
    public String getUrl(String resourceId) {
        List list = MainApplication.getResourceList();
        if (list == null || list.isEmpty()) {
            LegoLog.w("资源寻址返回值为空");
            return "";
        }
        for (ResourceInfo info : list) {
            if (info != null && resourceId.equals(info.getResourceId())) {
                return info.getResourceAddress();
            }
        }
        LegoLog.w("resourceId：" + resourceId + "未找到对应的服务信息");
        return "";
    }
}
