私はこの問題に数日間取り組んでいます。 CORSリクエストにCookieを設定します。 XHRリクエストでwithCredentials
がtrueに設定されていて、サーバーが適切なヘッダーを送信している限り、ブラウザーはSet-Cookie
ヘッダー。しかし、私のテストではそうではありませんでした。
const http = require('http');
const fs = require('fs');
// Pretty colors
const colors = {
purple: '\033[95m',
orange: '\033[93m',
blue: '\033[97m',
underline: '\033[4m',
bold: '\033[1m',
reset: '\033[0m'
}
const server = http.createServer(function (req, res) {
//Console logs to verify what's getting hit.
console.log(colors.purple + colors.underline + 'Hit it!' + colors.reset);
console.log(colors.orange + colors.bold + 'url:' + colors.reset, req.url);
if (/\/cookie/.test(req.url)) {
console.log(colors.blue + 'We need to cook(ie) Jesse\n' + colors.reset);
// Generate a random string in a rather convoluted way.
var randomStr = Math.floor(Math.random() * Number.MAX_SAFE_INTEGER).toString(36) +
Math.floor(Math.random() * Number.MAX_SAFE_INTEGER).toString(36) +
Math.floor(Math.random() * Number.MAX_SAFE_INTEGER).toString(36);
randomStr = new Buffer(randomStr.toString(), 'binary').toString('base64');
// All .dev domains pointed to localhost via dnsmasq, though a hosts file
// Update should also do the trick.
res.writeHead(200, {
'Set-Cookie': 'ajaxTestCookie=cookie' + randomStr + '; Domain=.example.dev; HttpOnly',
'Access-Control-Allow-Origin': 'http://example.dev:3999',
'Access-Control-Allow-Credentials': 'true',
'Access-Control-Allow-Methods': 'GET, POST',
'Access-Control-Allow-Headers': 'Content-Type, Set-Cookie, *'
});
return res.end('OK!');
}
console.log(colors.blue + 'We\'re having fun at the HTML!\n' + colors.reset);
// Send out html file.
fs.readFile('./cookies.html', function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Failure to launch!');
}
res.end(data.toString());
});
});
server.listen(3999);

私はFirefox Developer EditionとChromeの両方でこれをテストしてみましたが、ページに直接アクセスしない限り、Cookieは設定されません。
CORSリクエストでCookieを機能させるために欠けているものはありますか?
すぐにはわからなかったのは、少なくともCORSリクエストで、そしておそらく(おそらく)すべてのリクエストでサーバーによって設定されたCookieがサーバーと同じドメインに制限されていることです。
