项目之中遇到了OkHttp 请求超时以后就不能发送请求了，
解决办法是在onFail的里面再添加一下HttpClient.mOkHttpClient = new OkHttpClient();
public void onFailure(Call call, IOException e) {
HttpClient.mOkHttpClient = new OkHttpClient();
callback.onFailure(call,e);
}

Dorme的思路是考虑怎么我们之前的new OkHttpClient()没有执行，然后在哪里增加了一个记录发现果然没有执行，那么就增加了一个断电看看到底怎么执行的最后发现调用的地方原来不是之前的地方是别的地方就是下面的这个onFailure里面。
我需要把这样的思路给get了。感谢Dorme。

反思一下：其实我是过分的依赖网络了，因为我相信我遇到的问题别人一定也遇到了，所以我才没有深入的去debug，而是去上网查询，下一次再遇到这样给的事情，首先自己先debug，然后看看能不能在网上找到答案，一小段时间没有找到的话自己再debug。加油。。。
