前往：是否需要设置属性但没有指针接收器？

package main

import "fmt"

type MyClass struct{
    data    string
}

func (this MyClass) MyMethod() {
    this.data = "Changed!"
}

func main() {
    obj := MyClass{}

    obj.MyMethod()

    fmt.Println(obj)
}

I need that the data property gets changed by MyMethod(), but I cannot change the receiver type to pointer (func (this *MyClass)) because it must satisfy an interface whose receiver is not a pointer, can this achieved some other way?

You need to use a pointer receiver, not a value receiver:

func (this *MyClass) MyMethod() {
    this.data = "Changed!"
}

See your modified example in play.golang.org:

The output is:

{Changed!}
