Question

我正在尝试将网页发送到Chrome扩展程序，该扩展程序会在用户访问网站时触发（例如google）

的manifest.json

{
  "manifest_version": 2,
  "name": "Test Addon",
  "version": "0.01",
  "icons": { "16": "icon-16.ico" },

  "browser_action": {
  "default_icon" : "icon-16.ico",
  "default_popup" : "popup.html"
  },

   "content_scripts": [
    {
      "matches": ["*://*.google.com/*"  ],
      "js": ["cs.js"]
    }
  ],

  "externally_connectable": {
  "matches": ["*://*.mywebsite.com/*"]
}


}

cs.js

chrome.runtime.onMessageExternal.addListener(
  function(request, sender, sendResponse) {
    alert("world");
  });

mywebsite.com/testpage.php

// The ID of my chrome extension (In developer mode)
var editorExtensionId = "cjgeckgdpfhnedenpkaanpehddchlkle";

// Send a message
chrome.runtime.sendMessage("Hello");

</script>

据我所知，内容脚本可以访问onMessage和sendMessage但我在访问google时没有收到提醒

根据docs，扩展ID应该是调用sendMessage()时的第一个参数。你只是省略了这个参数第二个问题是来自外部网页的消息只能接收后台脚本。查看onMessageExternal() // The ID of my chrome extension (In developer mode) var editorExtensionId = "cjgeckgdpfhnedenpkaanpehddchlkle"; // Send a message chrome.runtime.sendMessage(editorExtensionId, "Hello"); 使用此代码将消息发送到后台扩展脚本：

import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;


public class MainActivity extends AppCompatActivity {

@SuppressLint("ShowToast")
@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
    setSupportActionBar(myToolbar);

邮件从外部网页传递到chrome插件
