本地Apache服务器配置及Android模拟器的调试

1.Apache的配置方式：https://jingyan.baidu.com/article/d8072ac47baf0eec95cefdca.html

按照这个配置就可以（删除一般会删除不干净，所以尽量不要删除。）

（这个一般用不到）http://kazake.blog.51cto.com/2155462/737847

下载的是最新的Apache，参考第一个连接下载的。

这样就配置好了！！！

2.OKHttp连接服务器，服务器本机地址为：https://127.0.0.1 

    

    在将get_data.json放置到合适的位置后为：

postman的运行结果：

重点强调：模拟器与本机IP地址不一样。

 模拟器IP为：https://10.0.2.2/get_data.json

如果这个没设置对，是无法实现连接的。

还有一点需要强调，使用OKHttp访问https类型的网站需要设置证书，这里我参考别人的代码实现的，最后顺利跑通，忙了一整天，各种坑都踩了。

 ssl证书参考博客：http://blog.csdn.net/okmin3/article/details/53585743
