golang : can't execute t. 执行

Question

我试图让一个处理程序在每次从提交按钮获取数据时更新一行， 这是我的代码:

func RowHandler(res http.ResponseWriter, req *http.Request) {
    if req.Method != "POST" {
        http.ServeFile(res, req, "homepage.html")
        return
    }
    Person_id := req.FormValue("Person_id")

    stmt, err := db.Prepare("update Cityes set Status='right' where  Person_id=?")

    if err != nil {

        log.Print("error ", err)
    }
    _, err = stmt.Exec(&Person_id)

    t, err := template.ParseFiles("city_update.html") //hier i just want to show a text in html Page

    if err != nil {
        log.Fatal(err)
    }
    err = t.Execute(res, "/city_update")

}

Answer 1

在这里而不是跟随

err = t.Execute(res, "/city_update")

将用于填充模板的数据作为发送参数发送到 Execute 而不是字符串。 link to doc

例如.

err = t.Execute(res,struct{ID string}{Person_id})
