我正在使用Phonegap和Phonegap Build开发应用程序。该应用程序已基本完成,但我没有处理推送通知。
我很难让设备甚至完全注册。我已将以下插件添加到我的项目中(在配置中为phonegap构建添加)https://github.com/phonegap/phonegap-plugin-push
我添加了插件并在我的javascript文件中有以下内容。
var app = {
// Application Constructor
initialize: function () {
this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function () {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
//
// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicitly call 'app.receivedEvent(...);'
onDeviceReady: function () {
app.receivedEvent('deviceready');
var push = PushNotification.init({
"android": {
"senderID": "1234567890"
},
"ios": { "alert": "true", "badge": "true", "sound": "true" },
"windows": {}
});
push.on('registration', function (data) {
console.log("registration event");
//document.getElementById("regId").innerHTML = data.registrationId;
alert(data.registrationId)
console.log(JSON.stringify(data));
});
push.on('notification', function (data) {
console.log("notification event");
console.log(JSON.stringify(data));
var cards = document.getElementById("cards");
var card = '<div class="row">' +
'<div class="col s12 m6">' +
' <div class="card darken-1">' +
' <div class="card-content black-text">' +
' <span class="card-title black-text">' + data.title + '</span>' +
' <p>' + data.message + '</p>' +
' </div>' +
' </div>' +
' </div>' +
'</div>';
cards.innerHTML += card;
push.finish(function () {
console.log('finish successfully called');
});
});
push.on('error', function (e) {
console.log("push error");
});
},
// Update DOM on a Received Event
receivedEvent: function (id) {
var parentElement = document.getElementById(id);
var listeningElement = parentElement.querySelector('.listening');
var receivedElement = parentElement.querySelector('.received');
listeningElement.setAttribute('style', 'display:none;');
receivedElement.setAttribute('style', 'display:block;');
console.log('Received Event: ' + id);
}
};
function successHandler(result) {
alert('result = ' + result); //Here you will get your device id.
}
function errorHandler(error) {
alert('error = ' + error);
}
所以,我不确定从哪里开始。我已经使用推送向导设置了一个帐户,并创建了其他证书,但这并没有提取任何设备,因为我认为没有设置为接收通知的设备。
所以我猜我的主要问题是,我是否遗漏了一些愚蠢的事情,比如注册阶段,我的设备已注册接收通知?

您没有正确使用this
上下文。这是一个常见的错误。 Javascript this
不像Java this
那样工作。
它不起作用的原因是因为this
在运行时而不是汇编时间(或编译时)得到解决)。触发事件后,this
将解析为全局this
,因为您的app
对象现已超出范围。该事件会在app
对象的* *之外触发。
快速解决方法是执行app.onDeviceReady
而非 您可以通过将this.onDeviceReady
onDeviceReady()
设为全局函数并离开{{1到位。

所以有2个部分,首先是jesseMonroy提到的,我的代码没有被正确选取,我的js文件没有正常运行。
第二部分是我没有调用注册函数,它允许你获得device_token。
push.registerDevice({ alert: true, badge: true, sound: true }, function (status) {
app.myLog.value += JSON.stringify(['registerDevice status: ', status]) + "\n";
app.storeToken(status.deviceToken);
alert(status.deviceToken)
});
这就是我所缺少的。我的整个init部分看起来像这样;
var push = PushNotification.init({
"android": {
"senderID": "1234567890"
},
"ios": { "alert": "true", "badge": "true", "sound": "true" },
"windows": {}
});
push.on('registration', function (data) {
console.log("registration event");
//document.getElementById("regId").innerHTML = data.registrationId;
alert(data.registrationId)
console.log(JSON.stringify(data));
});
push.on('notification', function (data) {
console.log("notification event");
console.log(JSON.stringify(data));
var cards = document.getElementById("cards");
var card = '<div class="row">' +
'<div class="col s12 m6">' +
' <div class="card darken-1">' +
' <div class="card-content black-text">' +
' <span class="card-title black-text">' + data.title + '</span>' +
' <p>' + data.message + '</p>' +
' </div>' +
' </div>' +
' </div>' +
'</div>';
cards.innerHTML += card;
push.finish(function () {
console.log('finish successfully called');
});
});
push.on('error', function (e) {
console.log("push error");
});
// var pushNotification = window.plugins.PushNotification;
push.registerDevice({ alert: true, badge: true, sound: true }, function (status) {
app.myLog.value += JSON.stringify(['registerDevice status: ', status]) + "\n";
app.storeToken(status.deviceToken);
alert(status.deviceToken)
});
