结构体赋值，等同于拷贝了结构体中的变量，函数传参与赋值一样
package main import "fmt" type Phone struct { color string name string } func main() { // 赋值 phone1 :=Phone{"Red","Iphone"} phone2 := phone1 phone2.color = "Green" fmt.Println(phone1.color) fmt.Println(phone2.color) } //Red //Green
而指针只是拷贝了结构体的内存地址，修改会影响原来的值
package main import "fmt" type Phone struct { color string name string } func main() { // 赋值 phone1 :=&Phone{"Red","Iphone"} phone2 := phone1 phone2.color = "Green" fmt.Println(phone1.color) fmt.Println(phone2.color) } //Green //Green
