Here is the code that can report an error
```go
package main

"fmt"

"io"
"net/http"
"os"
"time"
)
type header struct {
Duration time.Duration `header:"duration"`

}
func needFix1() {
g := gin.Default()
g.GET("/", func(c *gin.Context) {
h := header{}
err := c.ShouldBindHeader(&h)
if err != nil {
c.JSON(500, fmt.Sprintf("fail:%s\n", err))
return
}
c.JSON(200, h)
})
g.Run(":8081")
}
func needFix2() {

err := c.ShouldBindHeader(&h)
if err != nil {
c.JSON(500, fmt.Sprintf("fail:%s\n", err))
return
}
c.JSON(200, h)
})
g.Run(":8082")
}
func sendNeedFix1() {
