尝试在Chrome扩展程序中发送ajax请求。我已经确认请求返回200响应，它应该只是console.log来测试＆＃39;。我不确定这里是否存在异常问题？我已经阅读了Chrome扩展程序＆＃39; addListener＆＃39;文档。
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"
