Question

我正在使用以下代码，它会生成一个player-id，但不会在onesignal服务器上创建id作为订阅者。我该如何解决？

我正在附加代码和错误。

错误：

PUT https://onesignal.com/api/v1/players/123232-33-44345-1234c-712312 400 ()
index.html:89 Uncaught (in promise) ReferenceError: OneSignalUserSubscription is not defined
    at index.html:89
    at <anonymous>

Answer 1

您应该使用浏览器控制台查看400错误响应中的响应正文。这应该解释导致400错误的原因。

另外，您正在调用名为OneSignalUserSubscription的函数，但此函数未在您的代码中定义，这就是您获得ReferenceError的原因。

单击订阅按钮后，onesignal不会在信号服务器上注册playerid
