Golang如何将字符串切片转换为字符串？

Question

报错如下：

ubuntu@buildserver:~/gospace$ go build src/runk/test.go
# command-line-arguments
src/runk/test.go:8: cannot convert myvar (type []string) to type string
ubuntu@buildserver:~/gospace$

下面是代码：

ubuntu@buildserver:~/gospace$ cat src/run/test.go
package main

func Test() string {

    var myvar []string
    myvar = append(myvar, "hello world")

    return string(myvar)

}

func main() {
    Test()
}
ubuntu@buildserver:~/gospace$

Answer 1

myvar is a slice of strings, and you want a single string? If you just want to concatinate them you can use strings.Join(myvar,"").

Or not make a string slice in the first place:

myvar := ""
myvar += "hello, world!"
return myvar
