[英]AWS websocket server: 403 error when connecting from browser, fine from Python
I deployed a websocket server on an AWS EC2 instance. 我在AWS EC2实例上部署了websocket服务器。 I am able to connect to this websocket without any issues from a Python script (using websocket.create_connection), but I get a 403 error when running the Javascript line var ws = new Websocket(.....)
in Chrome: Error during WebSocket handshake: Unexpected response code: 403
. 我能够从Python脚本连接到此websocket,而没有任何问题(使用websocket.create_connection),但是在Chrome中运行Javascript行var ws = new Websocket(.....)
时出现403错误:发生Error during WebSocket handshake: Unexpected response code: 403
。
I made sure to change the security group on the EC2 instance to allow all inbound and outbound traffic. 我确保更改EC2实例上的安全组,以允许所有入站和出站流量。
All suggestions appreciated! 所有建议表示赞赏!
EDIT: Figured out what was going on here. 编辑:弄清楚这里发生了什么。 It was an issue with the default origin check function in my Go websocket server. 我的Go websocket服务器中的默认来源检查功能存在问题。
This was a server-side issue with the gorilla/websocket package. 这是大猩猩/ websocket软件包的服务器端问题。 Had to add this CheckOrigin function: 必须添加此CheckOrigin函数:
var upgrader = websocket.Upgrader{
ReadBufferSize: 1024,
WriteBufferSize: 1024,
CheckOrigin: func(r *http.Request) bool {return true},
}
