嘗試在Chrome擴展程序中發(fā)送ajax請求。我已經確認請求返回200響應，它應該只是console.log來測試＆＃39;。我不確定這里是否存在異常問題？我已經閱讀了Chrome擴展程序＆＃39; addListener＆＃39;文檔。

content.js

chrome.runtime.sendMessage({greeting: "hello"}, function(response) {

console.log(response.farewell); //this is not working

return true;

});

background.js

require('./modules/communicate.js');

var communicate = new Communicate();

chrome.runtime.onMessage.addListener(

function(request, sender, sendResponse) {

if (request.greeting === "hello") {

response = communicate.talk('http://127.0.0.1:5000/test', 'GET');

sendResponse({

farewell: response

});

return true; //doing this correctly?

}

});

communicate.js

Communicate = function() {

this.talk = function(url, method) {

$.ajax({

url: url,

method: method,

success: function(result) {

return result;

}

});

};

};

的manifest.json

{

"manifest_version": 2,

"icons": { "128": "images/icon.png" },

"browser_action": {

"default_icon": "images/icon.png",

"default_popup": "html/popup.html"

},

"background": { "scripts": ["js/background.js"] },

"content_scripts": [{

"matches": [ "http://*/*", "https://*/*" ],

"js": [ "js/content.js" ]

}],

"permissions": [ "" ],

"web_accessible_resources": [ "js/*", "html/*", "css/*", "images/*" ],

"content_security_policy": "script-src 'self'; object-src 'self'"

}
