javascript - 自定义域 WebSocket 握手错误

Question

我的服务器上不断出现此错误:[error] Could not check origin for Phoenix.Socket transport.

我在 myapp.herokuapp.com 上有一个在 heroku 上运行的 Phoenix 和 JS 应用程序，它使用了 channel 。

我关注了 heroku custom domain在将我的 prod.exs 配置更改为:url: [scheme: "https", host: "myapp.com", port: 443] 后，现在无法加载我的应用程序的 javascript
从: url: [方案: "https", 主机: "myapp.herokuapp.com", 端口: 443]


使用自定义域 myapp.com 访问应用程序时出现此 JS 错误:

WebSocket connection to 'wss://myapp.com/socket/websocket?token=undefined&vsn=1.0.0' failed: Error during WebSocket handshake: Unexpected response code: 400

当我将配置保留为 url: [scheme: "https", host: "myapp.herokuapp.com", port: 443] 访问 myapp.herokuapp.com 时我没有收到任何错误，但是当我访问 myapp.com 时，我在 JS 控制台中收到以下错误:

我尝试将 check_origin 设置为 false，但它也不起作用。访问 myapp.com 时，heroku 日志不再显示错误。

heroku[router]: at=info method=GET path="/socket/websocket?token=undefined&vsn=1.0.0" host=myapp.com request_id=379b61c9-94be-4a1c-ac43-419e9554ac51 fwd="2601:602:9301:2b00:3c91:6660:9593:ad2c,2601:0602:9301:2b00:3c91:6660:9593:ad2c,108.162.245.122" dyno=web.1 connect=1ms service=1ms status=400 bytes=119

但我仍然在 JS 控制台中得到这个:

WebSocket connection to 'wss://myapp.com/socket/websocket?token=undefined&vsn=1.0.0' failed: Error during WebSocket handshake: Unexpected response code: 400

我的应用端点的完整配置

config :my_app, MyApp.Endpoint,
  http: [port: {:system, "PORT"}],
  url: [scheme: "https", host: "myapp.com", port: 443],
  check_origin: false,
  force_ssl: [rewrite_on: [:x_forwarded_proto]],
  cache_static_manifest: "priv/static/manifest.json",
  secret_key_base: System.get_env("SECRET_KEY_BASE")

编辑:为了值得，我将 cloudflare 用于我的 dns，并将 ssl 选项设置为 full。

---

编辑 2:如果我在我的配置中保留 check_origin: false 并且我更改我的 socket.js 文件，我可以加载 myapp.com:

let socket = new Socket("/socket", {params: {token: window.userToken}})

到:

let socket = new Socket("wss://myapp.herokuapp.com/socket", {params: {token: window.userToken}})

因为我不想让 check_origin 保持错误，所以我尝试将其更新为:

url: [scheme: "https", host: "myapp.com", port: 443],
  check_origin: ["myapp.com", "myapp.herokuapp.com", "//myapp.com", "//myapp.herokuapp.com"],

使用这些新设置重新编译应用程序后，当我尝试访问 myapp.com 时，它在控制台中留下了这个 JS 错误:

WebSocket connection to 'wss://myapp.herokuapp.com/socket/websocket?token=undefined&vsn=1.0.0' failed: Error during WebSocket handshake: Unexpected response code: 503

Answer 1

第一个问题在于使用 heroku 和 cloudflare。 This article说它不能用自定义url来完成，你只能用默认的heroku url来使用它 https://support.cloudflare.com/hc/en-us/articles/205893698-Configure-Cloudflare-and-Heroku-over-HTTPS

也就是说，在没有使用 cloudflare 的情况下，我也遇到了问题。对我有用的是- 将 check_origin 参数设置为您正在访问的 url 的完整路径。对我来说，我也在使用 www，所以我的配置看起来像这样

url: [scheme: "https", host: "myapp.com", port: 443],
check_origin: [
  "https://myapp.com",
  "https://www.myapp.com"
],

(我的其他配置和你的一样)
