phpstorm 和 pycharm
server选项里边输入 http://idea.imsxm.com/
IntelliJ IDEA
1. 到网站 http://idea.lanyus.com/ 获取注册码
2.填入下面的license server:
http://intellij.mandroid.cn/
http://idea.imsxm.com/
http://idea.iteblog.com/key.php
不过很不幸，license server 的几个服务器地址，全部被JetBrains封杀。
访问 http://idea.lanyus.com/网站，也是看到这样的公告：
*.lanyus.com及*.qinxi1992.cn下的全部授权服务器已遭JetBrains封杀 ，请搭建自己的IntelliJ IDEA授权服务器，教程在...
所以，除开购买正版以外，就只能要么自己搭建授权服务器，要么用注册码。
IntelliJ IDEA2017 激活方法（亲测可用）：
搭建自己的授权服务器，对大佬来说也很简单，我作为菜鸟就不说了，网上有教程。
我主要说第二种，现在，直接写入注册码，是不能成功激活的（如果你成功了，那当然好，如果不行，按照下面步骤操作）
1、进到文件夹中：C:WindowsSystem32driversetc ，找到hosts文件，用记事本编辑
2、如果没有找到hosts文件，可在查看设置中勾选“显示隐藏的项目”，不会的可百度“设置查看隐藏文件”，看见hosts文件直接看第4步。
3、如果依然没有，那么就需要自己在桌面新建一个空的记事本（有些系统因为权限问题，无法直接在当前文件夹中新建文本），在查看设置中，勾选显示“文件扩展名”，然后重命名为“hosts”，切记，删除后缀名！
4、将“ 0.0.0.0 account.jetbrains.com ”添加到hosts文件中
5.进入 http://idea.lanyus.com/ ，点获取注册码
最后打开idea，将注册码粘贴即可。
ok，搞定。不过最后还是要说一下，如果有条件，还是买正版吧。
