当应用程序未在后台运行时，不会触发电子"打开网址"事件

Question

当我在macOS上运行电子应用程序时，我想读取deeplinkingUrl附带的所有参数。当我的应用程序在Windows上通过协议调用时，我可以从process.argv中获得深度链接URL。但这在macOS上是不可能的，因为process.argv给出-psn...，并且在应用程序首次启动时只给出一次该参数。

当我的应用程序不在macOS后台运行时，我想通过从浏览器调用协议来触发open-url。但此事件仅在应用程序运行时触发。当应用程序未运行时，应用程序将显示，但它不会根据深度链接URL附带的操作进行导航。

我也在package.json:中写过这些

"protocols": {
"name": "My App",
"schemes": [
"myapp"
]
}

来自electron.js:的

let clickToCallObj = {};
let deeplinkingUrl;
let mainWindow;
app.on('open-url', (event, url) => {
event.preventDefault();
const isDefaultProtocolClientSet = app.isDefaultProtocolClient('myapp');
deeplinkingUrl = url;
clickToCallObj.operation = utils.getOperation(deeplinkingUrl); //e.g. myapp:/call/12345 -> operation: call
if (mainWindow && isDefaultProtocolClientSet) {
mainWindow.isMinimized() ? mainWindow.restore() : null;
mainWindow.focus();
sendClickToCallEvent(clickToCallObj, deeplinkingUrl); //takes the action with coming operation and deeplinkingUrl
}
});

那么，当我在macOS上调用我的应用程序时，当它不在后台运行时，我如何获得深度链接URL呢？

Answer 1

1. app.on('will-finish-launching', )事件应在app.on('ready', )之前捕获
2. isInvokedWhileAppIsNotRunning参数被设置为true，并且在应用程序加载完成之后被控制

3. Based on electron documentation, open-url event has used in will-finish-launching event regarding their occurrence order.

   // Protocol handler for osx while application is not running in the background.
   app.on ('will-finish-launching' , () => {
   app.on('open-url', (event, url) => {
   
   event.preventDefault();
   deeplinkingUrl = url;
   const isDefaultProtocolClientSet    = app.isDefaultProtocolClient(getProtocolName());
   clickToCallObj.operation            = utils.getOperation(deeplinkingUrl);
   if (isDefaultProtocolClientSet) {
   clickToCallObj.isInvokedWhileAppIsNotRunning = true;
   }
   });
   });
   // Protocol handler for osx while the app is running in the background
   app.on('open-url', (event, url) => {
   event.preventDefault();
   const isDefaultProtocolClientSet = app.isDefaultProtocolClient(getProtocolName());
   clickToCallObj.operation = utils.getOperation(url);
   if (mainWindow && isDefaultProtocolClientSet) {
   mainWindow.isMinimized() ? mainWindow.restore() : null;
   mainWindow.focus();
   sendClickToCallEvent(clickToCallObj, url);
   }
   });
