 - 调用IsvGetPermanentCode
 - 调用IsvActivateSuite给企业激活套件
 - 调用IsvGetCorpAccessToken获取企业的access_token

-- **只有isv的suite_access_token是单例的。**
-- **corp_access_token是不同的，企业a换取来的corp_access_token是1，企业b换取来的corp_access_token是2。**
-- **建议：isv可以用Redis，总之是这种key-value的存储来维护corp_access_token，企业的永久授权码是不会变的。**
-- **在没过期之前，根据永久授权码从map里拿corp_access_token，如果过期了，又走一次流程，换取新的永久授权码，继续存入map，更新key-value系统。**
