Question

IO error: .../LOCK: No further details.

(IO错误：... / LOCK：无更多详细信息。)

popup.js

(popup.js)

$(document).ready(function() {

 var access_token;

  // Send message to background.js
  chrome.runtime.sendMessage({msg: "getToken"}, function(token) {
    if(token) {
      access_token = token;
      userLoggedIn();
    } else {
      showLoginPage();
    }
  });

  chrome.storage.onChanged.addListener(function (changes,areaName) {
    if(changes.token.newValue) {
      access_token = changes.token.newValue;
      userLoggedIn();
    } else {
      showLoginPage();
    }

  });

 // When clicked on login button, this will launch an oauth window and save token in storage. This is working fine.
 $('#login-btn').click(function() {
   chrome.extension.getBackgroundPage().getAccessToken();
 });

 // When user logs out, this will revoke the oauth token, this is working fine.
 $('#logout-btn').click(function() {
   chrome.extension.getBackgroundPage().revokeAccessToken(access_token);
 });

});

background.js

(background.js)

var token;

// Check for token in storage
function checkAccessToken() {
  chrome.storage.sync.get("token", function(result){

    if(chrome.runtime.lastError) {
      console.log(chrome.runtime.lastError.message); // Error here
    } else {
      if('token' in result) {
        token = result.token;
      }

    }
  });
}

checkAccessToken();

// Listen to messages from popup.js
chrome.runtime.onMessage.addListener(
 function(request, sender, sendResponse) {
   if (request.msg === "getToken") {
     sendResponse(token);
   }
 });

function getAccessToken() {
  // code
}

function revokeAccessToken(token) {
  // code
}
