Question

使用带有ColdFusion的Java Apple推送通知服务库（http://notnoop.github.io/java-apns/）测试推送通知时，我有奇怪/间歇的结果。

以下是有效的Payload字符串示例：

{"aps":{"alert":"dsfkjsdlfkjasdlfkjsdlfkjasdlkfjasldfkjasldkfjasdlkfjasldkfjasldkfjasdlkfjasldkfjasdlkfjasdlfkjasdlkfjasdlkfjasldkfjasldkfjasldkfjasldkfjasldkfjasldkfjasldkfjalsdkfjlasdkfjaslkdjf"},"ID":"431"}

当我发送包含其他自定义字段的通知时，＆＃34;短＆＃34;消息文本，它通过。样品：

{"ALERTTYPE":"Collection","ID":"427","ALERTVALUE":"50","aps":{"alert":"005 - Source: Eric Dev PC;"}}

然而，当我尝试用＆＃34;更长的＆＃34;发送通知时文字，通知不会通过。

例如，我发送了一个带有Link to Collection的通知，消息文本为“004 - Source：Eric Dev PC;”，我收到了它，但是，当我发送带有Link to Collection和消息的通知时文字“004 - 资料来源：Eric Dev PC;证书：ABC123;链接到收藏：收集123;“，它没有通过。在尝试推送它之前，我检查了“较长”的有效载荷，并且它不大 - 158字节（我相信最大值是2048字节）。我还使用isTooLong()方法检查有效负载并使用shrinkBody()将其缩短以确保有效负载不会太大。

{"ALERTTYPE":"Collection","ID":"427","ALERTVALUE":"50","aps":{"alert":"005 - Source: Eric Dev PC; Certificate: ABC123; Link to Collection: Collection 123;"}}

同样，此有效负载远低于阈值。

这是我的代码：

//  Create the ApnsService object
LOCAL.ApnsService =
    CreateObject("java", "com.notnoop.apns.APNS")
        .newService()
        .withCert(
            VARIABLES.ApnsCertificate["filePath"],
            VARIABLES.ApnsCertificate["password"]
            )
        .withProductionDestination()
        .build();

//  Start the Apns service
LOCAL.ApnsService.start();

//  Set default value for Connection Test status
LOCAL.ConnectionTestSuccess = true;

/*
    Test the connection - this will throw an exception if the Apple
    servers aren't reachable or the service cannot send
    notifications for now (attempt will be made at next scheduled
    time)
*/
try {
    LOCAL.ApnsService.testConnection();
}
catch (any error){
    LOCAL.ConnectionTestSuccess = false;
}

//  Connection Test worked, so attempt to send the Notification
if  (LOCAL.ConnectionTestSuccess) {
    /*
        Before attempting to send the push notification, retrieve
        and deactivate inactive device tokens to prevent issues
        with Apple
    */
    deleteInactiveDevices(apnsCert=VARIABLES.ApnsCertificate);

    //  Retrieve all User Device Tokens for this Push Notification
    LOCAL.qUserDeviceTokens = getUserDeviceTokens();

    LOCAL.aDeviceTokens =
        ListToArray(ValueList(LOCAL.qUserDeviceTokens.DEVICETOKEN));

    //  Generate a Payload Builder instance
    LOCAL.PayloadBuilder =
        CreateObject("java", "com.notnoop.apns.APNS")
            .newPayload();

    //  Add the alert body to the payload
    LOCAL.PayloadBuilder
        .alertBody(Trim(VARIABLES.MessageText));

    //  Build the Custom Fields object/structure
    LOCAL.CustomFields.id = VARIABLES.Id;

    //  Link to News Article
    if  (Len(Trim(VARIABLES.NewsArticleId))) {
        LOCAL.CustomFields.alertType = "News";
        LOCAL.CustomFields.alertValue = Trim(VARIABLES.NewsArticleId);
    }
    //  Link to Collection
    else if  (Len(Trim(VARIABLES.CollectionId))) {
        LOCAL.CustomFields.alertType = "Collection";
        LOCAL.CustomFields.alertValue = Trim(VARIABLES.CollectionId);
    }
    //  Link to Search Results
    else if (Len(Trim(VARIABLES.SearchText))) {
        LOCAL.CustomFields.alertType = "Search";
        LOCAL.CustomFields.alertValue = Trim(VARIABLES.SearchText);
    }

    //  Add Custom Fields to the Payload
    LOCAL.PayloadBuilder
        .customFields(LOCAL.CustomFields);

    /*
        Shrink the alert body so that the entire payload
        string will fit within Apple's byte limit
    */
    if  (LOCAL.PayloadBuilder.isTooLong()) {
        LOCAL.PayloadBuilder
            .shrinkBody("...");
    }

    LOCAL.PayloadJSONString =
        LOCAL.PayloadBuilder
            .build();

    /*
        Push the notification through Apple's APNS;
            Note: push() accepts a Java Collection and a Java
            String. ColdFusion Arrays are already typed as Java
            Collections, so there is no need to recast it
    */
    LOCAL.Notifications =
        LOCAL.ApnsService
            .push(
                LOCAL.aDeviceTokens,
                JavaCast("string", LOCAL.PayloadJSONString)
            );

//  Stop the Apns service
LOCAL.ApnsService.stop();

快速更新......我发送了一堆带有其他自定义字段的通知，并逐个减少了消息文本中的字符数。如果消息文本包含32个字符或更少（Payload字节长度= 107） - 它们似乎更多，并且没有收到通知。似乎是随意的......令人费解...
