我需要从网页按钮点击启动Chrome应用程序.我找到了以下资源,'
这建议使用external_connectable和url_handlers,但似乎不起作用.有没有正确的方法可以通过调用chrome app extension id来点击网页上的按钮来启动Chrome应用程序?
我是这个领域的新手,非常感谢你们专家给予的任何帮助:)
PS
我在网页上单击按钮时尝试了以下命令,
chrome.management.launchApp('app id');
这导致了错误Uncaught TypeError: Cannot read property 'launchApp' of undefined
.
我找到了如何实现这一目标,其他人遇到了这个问题.
在您的网页上点击按钮,例如,包含以下代码,
//data passed from web to chrome app
chrome.runtime.sendMessage('your_chrome_app_id', { message: "version" },
function (reply) {
if (reply) {
if (reply.version) {
//log the response received from the chrome application
console.log(reply.version);
}
}
}
);
Run Code Online (Sandbox Code Playgroud)在您的chrome应用程序manifest.json中定义externally_connectable
url/urls,如下所示,
{
"name": "App name",
"description": "App Desc",
"version": "1",
...
"externally_connectable": {
"matches": ["*://localhost:*/"]
}
}
Run Code Online (Sandbox Code Playgroud)在您的应用程序background.js中设置一个侦听器,当从网页发送消息时调用该侦听器,如下所示,
chrome.runtime.onMessageExternal.addListener(
function(request, sender, sendResponse) {
if (request) {
if (request.message) {
if (request.message == "version") {
//my chrome application initial load screen is login.html
window.open('login.html');
//if required can send a response back to the web site aswell. I have logged the reply on the web site
sendResponse({version: '1.1.1'});
}
}
}
return true;
});
