byteArray := []byte{'H','E','L','L','O'} str1 := bytes.NewBuffer(byteArray).String() fmt.Println("String =",str1) } Output: String = HELLO 3. Using fmt.Sprintf() function to convert byte array to string This is a workaround way to convert byte array to string. The Spri...
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...
对于[]byte来说,array指向的就是byte数组。 1.png string 关于string类型,在go标准库builtin中有如下说明: // string is the set of all strings of 8-bit bytes, conventionally but not// necessarily representing UTF-8-encoded text. A string may be empty, but// not nil. Values of string type ...
type byte = uint8 在go的源码中src/runtime/slice.go,slice的定义如下: type slice struct { array unsafe.Pointer len int cap int } array是底层数组的指针,len表示长度,cap表示容量。对于[]byte来说,array指向的就是byte数组。 string 关于string类型,在go标准库builtin中有如下说明: // string is...
str := string(bytes) bytes[0] = 'i'//注意这一行,bytes在这里修改了数据,但是str打印出来的依然没变化, fmt.Println(str) } to package main import ( "fmt" "unsafe" ) func main() { bytes := []byte("I am byte array !") str := (*string)(unsafe.Pointer(&bytes)) ...

fileData := string(fileBytes) // Convert bytes to string fmt.Println(fileData) } In this example, we read the contents of a file named “data.txt” into a byte array usingioutil.ReadFile(). Next, we convert the byte array to a string usingstring(). This conversion enables us to ...
s := *(*string)(unsafe.Pointer(&ss))returns } 哈哈,其实就是byte数组,而且要注意string其实就是个struct。 何为[]byte? 首先在go里面,byte是uint8的别名。而slice结构在go的源码中src/runtime/slice.go定义: typeslicestruct{ array unsafe.Pointerlenintcapint} ...
