简介： Could not obtain connection to query metadata : Public Key Retrieval is not allowed

您应该将客户端选项添加到 MySQL 连接器中，

allowPublicKeyRetrieval=true

以允许客户端自动从服务器请求公钥。

AllowPublicKeyRetrieval=True

允许恶意代理执行 MITM 攻击以获取纯文本密码，因此默认情况下它是false！必须显式开启。

也可以使用如下配置：

useSSL=false

所以，最终修改 db 配置如下即可：

jdbc:mysql://localhost:3306/db?allowPublicKeyRetrieval=true&useSSL=false

C#—Collection was modified;enumeration operation may not execute
错误 Collection was modified; enumeration operation may not execute翻译是 集合已修改；枚举操作可能无法执行。也就是说我们在遍历集合等可迭代元素时，进行了集合的修改导致的错误。本质上因为Collection返回的IEnumerator把当前的属性暴露为只读属性，所以对其的修改会导致运行时错误，只需要把foreach改为for来遍...
