在这种情况下，如何用go将整数更改为字符串？

Question

Using gorm to connect db. Here get all the records:

  func GetPeople(c *gin.Context) {
         var people []Person
         var count int

         find_people := db.Find(&people)
         find_people.Count(&count)
         if err := find_people.Error; err != nil {
                 c.AbortWithStatus(404)
                 fmt.Println(err)
         } else {
                 c.Header("X-Total-Count", &count)
                 c.JSON(200, people)
         }
  }

About count, the c.Header("X-Total-Count", &count) can't passed since this error:

cannot use &count (type *int) as type string in argument to c.Header

Have tried strconv.Itoa(&count), got another error:

cannot use &count (type *int) as type int in argument to strconv.Itoa

So how to convert integer to string in this case?

Answer 1

In the c.Header() call pass the value of the variable instead of a pointer.

c.Header("X-Total-Count", strconv.Itoa(count))

For reference, the method signature is:

func (c *Context) Header(key, value string) {
