go 中string与[]byte的互换,相信每一位 gopher 都能立刻想到以下的转换方式,我们将之称为标准转换。 // string to []byte s1 := "hello" b := []byte(s1) // []byte to string s2 := string(b) 强转换 通过unsafe 和 reflect 包,可以实现另外一种转换方式,我们将之称为强转换(也常常被人称作黑...
prog.go:8: cannot convert "abcde" (type string) to type [5]uint8 直接用copy(t.f1,"abcde")也是不行的。。因为copy的第一个参数必须是slice, 方案1:利用f1[:],注意,这里f1实际上是一个fixed的array,而f1[:]是一个slice packagemainimport"fmt"typeT1struct{ f1 [5]bytef2int}funcmain(){ t :...
To modify the content of a string, you could convert it to abytearray. But in fact, youdo notoperate on the original string, just a copy: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 packagemainimport"fmt"funcmain(){s:="Hello"b:=[]byte(s)b[0]='h'fmt.Printf("%s\n",b)}...
