[GitHub] [servicecomb-java-chassis] zhufeizzz opened a new issue, #3820: ServiceComb是否可以动态进行Provider端的HTTP和HTTPS切换？
zhufeizzz opened a new issue, #3820:
URL: https://github.com/apache/servicecomb-java-chassis/issues/3820
目前我们系统使用的是服务端HTTPS模式，准备切换成HTTP模式，有几个问题：
1、会不会因为服务是Production状态，并且服务版本号未发生变化，导致服务启动注册Schema失败。
2、CSE服务端变更后，所有的客户端是否需要重启，包括JavaSDK和Mesher。如果不需要重启业务中断时间大概是多久。
3、是否可以支持系统一部分服务使用HTTP，一部分使用HTTPS。

3.0.0会考虑支持这种场景。

契约中包含了endpoint的信息，导致接口定义没变，仅仅是http schema变了，也被判定为契约变化
感觉可以优化，但是成本不低，好像还有兼容问题
大概也许可能，用允许契约覆盖的版本可以规避
不过，契约覆盖，违反了当初的设计基础准则，不知道有没有什么副作用

第二个问题很难说得通，ServiceComb一直在说编程模型和通信模型解耦，HTTP Schema应该属于通信模型的一部分（跟IP/Port保持一致），为啥调整通信模型还要强制刷新版本号呢。

你可以先做一个验证。服务端能够正常启动起来并注册，和改成HTTP之前，做普通升级是一样的。

@liubao68 已经试了
1、Mesher不支持动态判断服务端是否开启SSL，只能在配置文件中写死协议类型，也就是说全系统必须统一为HTTP或HTTPS。
2、服务端Production状态下如果修改HTTP协议会报Schema禁止修改错误。

你说的第一个问题，看起来是 `Mesher` 的限制， 和 java chassis 无关
第二个问题是 java chassis不允许契约覆盖，比较好的实践是修改版本号(microservcie.yaml）定义， 或者升级到最新版本， 最新版本允许契约覆盖。
