我想在我的应用中集成一个小型聊天/即时消息功能,需要一些启动辅助工具。 我已注册Google云消息传递帐户并收到配置文件(" google-services.json",其中包含项目ID)和服务器API密钥。
第一个问题是:我是否必须在我的Google帐户中进行进一步设置,以便应用获取讯息功能所需的所有信息?
接下来的问题是,如何在我的项目中集成messenging函数。
我做了什么(以及什么似乎不起作用):
在我的index.html文件中,我集成了以下代码(XXXXXXXXX已替换为我的发件人ID):
<script type="text/javascript" src="PushNotification.js"></script>
<script>
var pushNotification;
function onDeviceReady() {
alert('Device is ready');
try {
pushNotification = window.plugins.pushNotification;
alert('Registering ' + device.platform);
if(device.platform == 'android' || device.platform == 'Android' ||device.platform == 'amazon-fireos' ) {
pushNotification.register(
successHandler,
errorHandler,
{
"senderID":"XXXXXXXXXXX",
"ecb":"onNotification"
});
alert('Registered the Android device');
alert('regID = ' + e.regid);
} else {
pushNotification.register(tokenHandler, errorHandler, {"badge":"true","sound":"true","alert":"true","ecb":"onNotificationAPN"});
alert('Registered the iOS device');
}
}
catch(err)
{
txt="There was an error on this page.\n\n";
txt+="Error description: " + err.message + "\n\n";
//alert(txt);
alert('Error: ' + err.message);
}
}
// handle APNS notifications for iOS
function onNotificationAPN(e) {
if(e.alert) {
// showing an alert also requires the org.apache.cordova.dialogs plugin
navigator.notification.alert(e.alert);
}
if(e.sound) {
// playing a sound also requires the org.apache.cordova.media plugin
var snd = new Media(e.sound);
snd.play();
}
if(e.badge) {
pushNotification.setApplicationIconBadgeNumber(successHandler, e.badge);
}
}
// handle GCM notifications for Android
function onNotification(e) {
alert('EVENT -> RECEIVED:' + e.event);
switch( e.event )
{
case 'registered':
if( e.regid.length > 0 )
{
// Your GCM push server needs to know the regID before it can push to this device
// here is where you might want to send it the regID for later use.
console.log("regID = " + e.regid);
alert(' REGID = ' + e.regid);
}
break;
case 'message':
// if this flag is set, this notification happened while we were in the foreground.
// you might want to play a sound to get the user's attention, throw up a dialog, etc.
if(e.foreground) {
alert('--INLINE NOTIFICATION--');
// on Android soundname is outside the payload.
// On Amazon FireOS all custom attributes are contained within payload
var soundfile = e.soundname || e.payload.sound;
// if the notification contains a soundname, play it.
// playing a sound also requires the org.apache.cordova.media plugin
var my_media = new Media("/android_asset/www/"+ soundfile);
my_media.play();
} else {
// otherwise we were launched because the user touched a notification in the notification tray.
if(e.coldstart)
//$("#app-status-ul").append('<li>--COLDSTART NOTIFICATION--' + '</li>');
alert('--COLDSTART NOTIFICATION--')
else
alert('--BACKGROUND NOTIFICATION--')
}
alert('MESSAGE -> MSG: ' + e.payload.message);
//android only
alert('MESSAGE -> MSGCNT: ' + e.payload.msgcnt);
//amazon-fireos only
alert('MESSAGE -> TIMESTAMP: ' + e.payload.timeStamp);
break;
case 'error':
//$("#app-status-ul").append('<li>ERROR -> MSG:' + e.msg + '</li>');
alert('ERROR -> MSG' + e.msg);
break;
default:
//$("#app-status-ul").append('<li>EVENT -> Unknown, an event was received and we do not know what it is</li>');
alert('EVENT -> Unknown, an event was received and we do not know what it is');
break;
}
}
function tokenHandler (result) {
// Your iOS push server needs to know the token before it can push to this device
// here is where you might want to send it the token for later use.
alert('iOS Result = ' + result);
}
function successHandler (result) {
alert('Android Result = ' + result);
alert('RegID = ' + e.regid);
}
function errorHandler (error) {
alert('Error = ' + error);
}
document.addEventListener('deviceready', onDeviceReady, true);
alert('regID = ' + e.regid);
alert('Reg code completed');
</script>
当我使用Phonegab Build时,我已将以下行添加到我的config.xml文件
<gap:plugin name="com.phonegap.plugins.pushplugin" version="2.4.0" />
以下插件(也使用过)已经是配置文件的一部分:
<gap:plugin name="org.apache.cordova.dialogs" />
<gap:plugin name="org.apache.cordova.media" />
我的主要问题是:
我在哪里放置Server API密钥? 我在哪里放置google-services.json文件(在哪个目录中)以及该文件如何链接到index.html
进一步的问题: - GCM服务真的免费吗?因为在会员区有一个展示&#34;本月的预计费用:0,00€&#34; - &GT;费用会增加吗? - 如果用户从Play商店下载并安装我的应用程序:他如何获得发件人ID以及我是否要向他发送消息 - &gt;我怎么知道他的发件人ID才能开始与他交流?
原则上我还没有理解GCM这个东西。 谁能给我一点帮助?
祝你好运

答案 0 :(得分:0)
GCM服务本身是免费的,如here所述。
我不熟悉设置Phonegap项目,但google-services.json
文件旨在与Gradle的Google服务插件一起使用。 Gradle本身是Android Studio使用的构建工具。我不确定Phonegap是否有类似的插件,但如果没有,你需要的是项目编号/发件人ID。您注册了您的应用程序/客户端。更多内容如下。
您在服务器代码中使用服务器API密钥,该服务器代码是将向您的应用发送消息的应用服务器。
更多关于注册的信息。您需要查看一些Phonegap教程,因为GCM的新(和推荐)注册方式是Instance IDs。它仍然使用相同的发件人ID,但您需要与Google Play服务进行交互才能执行此操作。
