我正在尝试使用此background.js获取cookie值
var myUrl = "https://cookiedomain.com/";
chrome.cookies.get({url: myUrl, name: 'email'}, function(cookie) {
var email = cookie.value;
chrome.runtime.sendMessage({ data: email });
});
chrome.cookies.get({url: myUrl, name: 'password'}, function(cookie) {
var password = cookie.value;
chrome.runtime.sendMessage({ data: password });
});
并在content.js中获取电子邮件,密码作为变量
chrome.runtime.onMessage.addListener(
function(request, sender, sendResponse) {
var email = request.email;
var password = request.password;
});
....
document.getElementById('id').value = email;
document.getElementById('id1').value = password ;
但似乎不起作用,任何人都可以帮助我吗?
谢谢大家。
你的代码中有几个问题:chrome.tabs.sendMessage应该与tab标签一起使用,两个document.getElementById行应该在onMessage回调中,你的后台脚本是在里面发送一个带有data
属性的对象,但是内容脚本期待email
和password
。
有一种更简单的方法:反转流程并让内容脚本向后台脚本发出请求,后台脚本将获取两个cookie并将其发送回一个响应中。
后台脚本:
chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
if (msg.topic === 'getAuth') {
chrome.cookies.get({url: msg.url, name: 'email'}, ({value: email}) => {
chrome.cookies.get({url: msg.url, name: 'password'}, ({value: password}) => {
sendResponse({email, password});
});
});
// keep sendResponse channel open
return true;
}
});
内容脚本:
chrome.runtime.sendMessage({
topic: 'getAuth',
url: location.href,
}, ({email, password}) => {
document.getElementById('id').value = email;
document.getElementById('id1').value = password;
});
