我正在成功獲取所有數(shù)據(jù)，并使用模板將其顯示在表格中。我在此代碼中使用Go查詢以Membership作為實(shí)體類型的數(shù)據(jù)存儲(chǔ)。在html頁(yè)面中，顯示所有數(shù)據(jù)，但不顯示鍵。我試圖添加Key *datastore.Key作為屬性的Membership結(jié)構(gòu)，但仍然沒(méi)有運(yùn)氣。這是我的代碼：package helloimport ( "appengine" "appengine/datastore" "html/template" "net/http" "time") type Membership struct { Key *datastore.Key Author string Content string FirstName string LastName string Address string Email string Grade string Date time.Time}func init() { http.HandleFunc("/", members)}func members(w http.ResponseWriter, r *http.Request) { c := appengine.NewContext(r) q := datastore.NewQuery("Membership").Order("-Date") memberships := make([]Membership, 0, 10) if _, err := q.GetAll(c, &memberships); err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return } if err := membersTemplate.Execute(w, memberships); err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) }}var membersTemplate = template.Must(template.New("page").Parse(membersTemplateHTML))const membersTemplateHTML = `<html> <body> <table><tr><th>Key</th><th>Name</th><th>Email</th><th>Adress</th><th>Grade</th></tr> {{range .}} <tr> <td>{{.Key}}</td> <td>{{.FirstName}} {{.LastName}}</td> <td>{{.Email}}</td> <td>{{.Address}}</td> <td>{{.Grade}}</td> </tr> {{end}} </table> </body></html>`
將* datastore.Key添加到切片
