我试图运行tabs.sendMessage()
MDN page上给出的示例代码。所以我的代码是:browser.tabs.sendMessage():错误:接收结束不存在
manifest.json的:
{
"manifest_version": 2,
"name": "test1",
"version": "1.0",
"description": "test",
"icons": {
"48": "icons/Ruler48.png"
},
"permissions": [
"notifications",
"tabs",
"activeTab"
],
"browser_action": {
"default_icon": "icons/Ruler48.png",
"default_title": "test"
},
"content_scripts": [{
"matches": ["*://*/"],
"js": ["content-script.js"]
}],
"background": {
"scripts": ["bgS.js"]
}
}
bgS.js:
function onError(error) {
console.error(`Error: ${error}`);
}
function sendMessageToTabs(tabs) {
for (let tab of tabs) {
console.log(tab.id);
browser.tabs.sendMessage(
tab.id,
{greeting: "Hi from background script"}
).then(response => {
console.log("Message from the content script:");
console.log(response.response);
}).catch(onError);
}
}
browser.browserAction.onClicked.addListener(() => {
browser.tabs.query({
currentWindow: true,
active: true
}).then(sendMessageToTabs).catch(onError);
});
内容的script.js:
browser.runtime.onMessage.addListener(request => {
console.log("Message from the background script:");
console.log(request.greeting);
return Promise.resolve({response: "Hi from content script"});
});
我与网络的内线运行运行它,点击浏览器的操作按钮,在控制台后,我得到这个消息:Error: Error: Could not establish connection. Receiving end does not exist.

这,什么浏览器控制台中,第一条消息出现在我安装它之前。我的意思是它在安装之前就已经存在了,所以它会默默安装。点击按钮后,我得到了最后的两个消息,第一个从该行给出tab.id
console.log(tab.id)
然后错误:

“浏览器控制台”(https://developer.mozilla.org/en-US/docs/Tools/Browser_Console)(Ctrl-Shift-J或Cmd-Shift- J在OSX上)当您尝试安装和使用扩展? – Makyen
单击浏览器动作按钮时,活动选项卡是否包含以“http://”或“https://”开头的URL的页面?你是否正在使用类似'about:addons'的URL来查看标签,'about:debugging'等?你是否试图在[AMO](https://addons.mozilla.org/)的页面上使用它? – Makyen
不知道你要求什么,但是当我运行它与网络分机运行--verbose我得到这个。我更新了问题。 – someNameJustToAnswer
