ChangeInterfaceToSlice 将 []interface{} 类型的切片转换成指定类型的切片 ChangeSliceToInterface 将任意切片类型的切片 转换为 []interface{} 类型 Contains 方法可以检查给定的切片中是否存在某个元素 ConvertSliceToMap 将结构体切片转出[]map[string]interface{} FindDiffVales 找到两个切片中不同的元素,返回两个...

func recoverinterface{} 运行时panic异常一旦被引发就会导致程序崩溃。 Go语言提供了专用于“拦截”运行时panic的内建函数“recover”。它可以是当前的程序从运行时panic的状态中恢复并重新获得流程控制权。 注意:recover只有在defer调用的函数中有效。 package main ...

In the Go language, to convert a string to a byte slice – we use the ByteSliceFromString() function of the syscall package. The ByteSliceFromString() function returns a NUL-terminated slice of bytes containing the text of s. If s contains a NUL byte at any location, it returns (nil...
