Question

当我使用APNS通知的属性调用Worklight过程时出现错误，特别是声音。

Eclipse中的错误：

[错误] FWLSE0099E：调用过程时发生错误 [project ExamplePushTags] PushTagAdapter / sendNotificationFWLSE0100E：参数：[project ExamplePushTags] TypeError：无法设置属性＆＃34; APNS＆＃34;未定义到＆＃34; [对象对象]＆＃34; （PushTagAdapter-impl.js＃30）

在导航器（safari）中显示：

{
       "errors": [
          "Ecma Error: TypeError: Cannot set property \"apns\" of undefined to \"[object Object]\" (PushTagAdapter-impl.js#30)"
       ],
       "info": [
       ],
       "isSuccessful": false,
       "warnings": [
       ]
    }

我的适配器PushTagAdapter-impl.js中的函数代码：

var applicationId = "ExamplePushTags";

function sendNotification (tag, notificationText, url) {

    var notification = {};

    notification.message = {};
    notification.message.alert = notificationText;

    notification.target = {};
    notification.target.tagNames = [tag];

    //set notification properties for APNS
    //error in this lines of code
    notification.settings.apns = {};
    notification.settings.apns.sound = 'sounds-865-fallin.mp3';


    WL.Server.sendMessage(applicationId, notification);
    WL.Logger.info("Notificacion enviada exitosamente " + JSON.stringify(notification));
    return { result: "Notification sent"};
}

注意：如果我对此行发表评论，我就不会遇到问题并且通知有效但我在每个通知中都需要声音。

我正在使用Worklight 6.2

您遗漏了notification.settings作为对象的定义

var applicationId = "ExamplePushTags";

function sendNotification (tag, notificationText, url) {

    var notification = {};

    notification.message = {};
    notification.message.alert = notificationText;

    notification.target = {};
    notification.target.tagNames = [tag];

    // missing this
    notification.settings = {};

    //set notification properties for APNS
    //error in this lines of code
    notification.settings.apns = {};
    notification.settings.apns.sound = 'sounds-865-fallin.mp3';
    // APNS payload here
    notification.settings.apns.payload = {};


    WL.Server.sendMessage(applicationId, notification);
    WL.Logger.info("Notificacion enviada exitosamente " + JSON.stringify(notification));
    return { result: "Notification sent"};
}

无法从未定义的Adapter-impl.js读取属性\“apns \”
