无法使用chrome.management API [英] Cannot use chrome.management API

问题描述

现在我想从一个chrome扩展中启动一个chrome应用程序（实际上，我想通过一个url启动chrome应用程序，但我不知道这一点）。
问题在这里。我添加了

 permissions：[
management
]，
  code> 

在扩展名清单中。但是，当我想通过使用

  chrome.management.launchApp（XXXX，function（）{}）启动应用程序时; 
  

，控制台说



未捕获TypeError：无法读取未定义的属性'launchApp'

所以我想知道为什么我不能使用chrome管理API。谢谢！

解决方案

一个解决方法可以在SO问题从网站按钮运行Chrome应用程序

• 在您想要调用Chrome应用程序的位置添加以下代码

    / /从网络传递给Chrome应用程序的数据
   chrome.runtime.sendMessage（'your_chrome_app_id'，{message：version}，
   function（reply）{
   if（reply）{
   if（reply.version）{
   //记录从chrome应用程序收到的响应
   console.log（reply.version）; 
  } 
  } 
   } 
  ）; 
    




• 在您的Chrome应用程序 manifest.json 中定义 externally_connectable url / url如下，
  
  

  {
  name：应用程序名称，
  description：App Desc，
  version：1，
  
  

    ... 
   
  externally_connectable：{
  matches：[*：// localhost：* /] 
  } 
  } 
    
   在应用程序 background.js 中设置一个侦听器，以便在从网页如下，
   
   
    chrome.runtime.onMessageExternal.addListener（
   function（request，sender，sendResponse）{ 
   if（request）{
   if（request.message）{
   if（request.message ==version）{
   
   // my chrome application initial加载屏幕是login.html 
   window.open（'login.html'）; 
   
   // if requi红色也可以将回复发回给网站。我在网站上记录了回复
   sendResponse（{version：'1.1.1'}）; 
  } 
  } 
  } 
  返回true; 
  }）; 
    
   
   
   

Now I want to start a chrome app from a chrome extension(in fact, I want to start chrome app through a url, which I have no idea to do). Here comes the question. I added

  "permissions": [
    "management"
  ],

in the manifest of extension. However, when I want to start app by using

chrome.management.launchApp("XXXX", function() {});

, the console says

Uncaught TypeError: Cannot read property 'launchApp' of undefined

So I wonder why I cannot use chrome management API. Thanks!

解决方案

A workaround for this is available at the SO question Run chrome application from a web site button

Copying Hasitha's answer here for direct reference.

• Add the following piece of code where you want to invoke the chrome app

                                                   //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);
              }
          }
      }
   );
  

• in your chrome application manifest.json define the externally_connectable url/ urls as follows,

  { "name": "App name", "description": "App Desc", "version": "1",

        ...
  
        "externally_connectable": {
          "matches": ["*://localhost:*/"]
        }
      }
  

• In your application background.js setup a listener to be invoked when a message is sent from the web page as follows,

  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;
    });
