一部分用户对把三段式 for loop (for i := 1; i < n; i++)中的循环变量也修改成 per iteration 这个提议提出了质疑,主要理由是会和其他语言(主要是C以及一众类C语言)的行为不一致,其他语言背景的用户迁移过来也会被坑到。(C# 迁移到 per-iteration 循环变量作用域的时候就只迁移了 foreach,而没更改三

在Go语言中,对Oracle进行操作,比访问其他常见DB可谓是要麻烦一些,显而易见的问题是库的选择,这里我尝试了两种库:go-ora + 官方库database/sql (github.com/jmoiron/sqlx、github.com/blockloop/scan 辅助)…

At this time, you can use the -g parameter to add the vps external network ip to prevent the infinite loop.Suppose your vps external network ip is 23.23.23.23. The following command sets 23.23.23.23 with the -g parameter.proxy http -g "23.23.23.23"...
