英文:
https://onesignal.com/api/v1//notifications: http.DefaultTransport and http.DefaultClient are not available in App Engine
问题
当我尝试在使用OneSignal环境的Golang App Engine中实现推送通知时，遇到了错误“App Engine中不可用http.DefaultTransport和http.DefaultClient”。这是我的代码：
func (c *PushNotificationController) CreateNotification() {
client := onesignal.NewClient(nil)
client.AppKey = "MyAppKey"
client.UserKey = "MyUserKey"
notifID := CreateNotifications(client)
log.Println(notifID)
}
func CreateNotifications(client *onesignal.Client) string {
playerID := "SamplePlayerId" // 有效的ID
notificationReq := &onesignal.NotificationRequest{
AppID: "MyAppKey",
Contents: map[string]string{"en": "English message"},
IsIOS: true,
IncludePlayerIDs: []string{playerID},
}
if createRes, res, err := client.Notifications.Create(notificationReq) {
if err != nil {
log.Fatal(err)
}
return createRes.ID
}
// ...
}
希望这可以帮助到你！

在App Engine上使用HTTP，你需要使用urlfetch。
https://cloud.google.com/appengine/docs/standard/go/urlfetch/reference
也就是说，你使用的包不支持App Engine。
英文:
Use http on appengine, you have to use urlfetch.
https://cloud.google.com/appengine/docs/standard/go/urlfetch/reference
i.e. the package you use doesn't support appengine.
