CustomDynamicInterceptor进行延时后两个异步请求的URL异常

在CustomDynamicInterceptor进行延时后，连续发送两个异步POST请求，前一个请求的url被后一个替换
一、BUG重现思路：
1.首先在CustomDynamicInterceptor增加sleep，使得两个请求顺序非同步（实际展示情况）进行。

```
public class CustomDynamicInterceptor extends BaseDynamicInterceptor<CustomDynamicInterceptor> {

@Override
    protected TreeMap<String, Object> updateDynamicParams(TreeMap<String, Object> dynamicMap) {
        if (isAccessToken()) {//是否添加token
            //需要添加token的时候 也需要添加这些参数,用户id、默认仓库、默认语言
            Logger.e("开始==="+DateUtils.getNowMills());
            User currentUser = UserTokenUtils.getLoginUser();
            try {
                Thread.sleep(1000);
            }catch(Exception e){
                e.printStackTrace();
            }
            //测试使用永久有效token
            dynamicMap.put("token", "");
            Logger.e("结束==="+DateUtils.getNowMills());
        }
        if (isSign()) {//是否添加签名
            dynamicMap.put("sign", "");
        }
        if (isTimeStamp()) {//是否添加请求时间戳
            dynamicMap.put("timeStamp", DateUtils.getNowMills());
        }
        return dynamicMap;//dynamicMap:是原有的全局参数+局部参数+新增的动态参数
    }
}
```
2.使用XHttp.post请求调用

```
XHttp.post("rfgetSectnByCctype")
                .upJson(new Gson().toJson(getSectn()))
                .keepJson(true)
                .accessToken(true)
                .syncRequest(false)
                .execute(sectnSimpleCallBack);
XHttp.post("rfgetMatno")
                .upJson(new Gson().toJson(getMatno()))
                .keepJson(true)
                .accessToken(true)
                .syncRequest(false)
                .execute(matnoSimpleCallBack);
```
二、结果展示

```
三、原因试分析
使用XHttp.get()进行试验，发现get请求不会出错，BaseDynamicInterceptor中addGetParamsSign中的url来自参数request本身【HttpUrl httpUrl = request.url();】，而addPostParamsSign的url来自mHttpUrl,后一个请求进入拦截器的时候覆盖了上一个请求的mHttpUrl,导致出错。

ps:问题描述如上，也可能是本人的使用方式有误，还望作者大大谅解，能指出使用错误之处，感谢。
