问题描述

我创建了一个简单的iOS本机应用程序，除了OneSignal初始化代码外，什么都没有.我在两个设备(设备A和设备B)上安装了我的应用程序.这两个设备都订阅了OneSignal应用程序控制台.当我从OneSignal Web控制台发送通知时，这两个设备都可以接收该通知.

I have created a simple iOS native App which has nothing but OneSignal initializaion codes. I installed my App on my 2 devices, device A and device B. Both devices are subscribed to my OneSignal App Console. When I send a notification from OneSignal Web Console, the 2 devices can both recive the notification.

当我单击设备A上的按钮时，设备A将向设备B发送通知.

When I click on a button on device A, device A will send a notification to device B.

我遵循OneSignal iOS SDK文档并创建了以下功能 https://documentation.onesignal.com/docs/ios- native-sdk#section-send-notifications

I followed the OneSignal iOS SDK document and created the following functionhttps://documentation.onesignal.com/docs/ios-native-sdk#section-sending-notifications

func onButtonClick() {
    OneSignal.postNotification(
        [
            "contents": ["en": "Test Message"],
            "include_player_ids": ["c00bb8a6-79da-419b-9999-e919831a5223"] // id of device B
        ],
        onSuccess: {(result) in print("success") },
        onFailure: {(error) in print("error : \(error)") }
    )
}

但是，当我单击按钮时，xCode调试控制台中显示了一个错误:

however, when I clicked the button, an error shows up in the xCode debug console:

2017-01-20 11:15:52.702852 my.bundle.id[2263:1201122] ERROR: Create notification failed
error : Optional(Error Domain=OneSignalError Code=400 "(null)" UserInfo={returned={
    errors =     (
        "Please include a case-sensitive header of Authorization: Basic <YOUR-REST-API-KEY-HERE> with a valid REST API key."
    );
    reference =     (
        "https://documentation.onesignal.com/docs/accounts-and-keys#section-keys-ids"
    );
}})

我很困惑，因为根据OneSignal参考文档，发送带有"include_player_ids"的通知.不需要API身份验证密钥.

I was confused, because according to the OneSignal Reference document, send notification with "include_player_ids" Does not require API Auth Key.

https://documentation.onesignal.com/reference#create-notification

它还说:切勿在客户端代码中使用"REST API密钥"，它仅可在您的系统或服务器上使用.

那么这个错误是什么意思?那我该怎么办?

So what does this error mean? And what should I do?

我什至从此讨论中复制并运行此没有任何问题的代码" /a>，但仍显示相同的授权错误.我在做什么错了?

I even copied and run this "work without any problems" code from this discussion, but the same Authorization error still shows up. What am I doing wrong?
