记录下开发遇到的小状况。
后台要求将userID放到请求url中，即：http://domin.com/用户ID。
参考了这位作者的处理方式，感谢他
直接贴代码：

import java.io.IOException;

import kotlin.Pair;
import okhttp3.HttpUrl;
import okhttp3.Interceptor;
import okhttp3.Request;

public class ChangeUrlIntercept implements Interceptor {

    private Context context;

    public ChangeUrlIntercept(Context context) {
        this.context = context;
    }

    @Override
    public okhttp3.Response intercept(Chain chain) throws IOException {
        //获取request
        Request request = chain.request();

        //获取request的创建者builder
        Request.Builder builder = request.newBuilder();
        //ALog.e( request.method());
        HttpUrl oldHttpUrl = request.url();
        //不能在登录接口里做此验证
        if (!request.method().equalsIgnoreCase("POST") 
        	  || !oldHttpUrl.toString().contains("Api/UserLogOn")) {
            Pair<Boolean, User> result = CommonUtils.getUser(context);
            if (result.component1()) {
                //重建新的HttpUrl，修改需要修改的url部分
                HttpUrl newFullUrl = oldHttpUrl
                        .newBuilder()
                        .scheme(oldHttpUrl.scheme())
                        .host(oldHttpUrl.host())
                        .port(oldHttpUrl.port())
                        .addEncodedPathSegment(result.component2().tskey)
                        .build();
                // ALog.e(newFullUrl.toString() + "  新的请求接口");
                return chain.proceed(builder.url(newFullUrl).build());
            } else {
                return chain.proceed(request);
            }

        }
        return chain.proceed(request);
    }
}
