错误：自签名证书尝试使用 vscode 扩展连接到 vis WSS

Question

我正在尝试连接到 wss。

var WebSocket = require('ws');
var webSocket = new WebSocket('wss://localhost:8443/cart'); 

它与正常的 javascript 连接没有错误。 但是当我试图用 vscode 扩展连接到这个时，它会给出一个错误，比如

events.js:167
      throw er; // Unhandled 'error' event
      ^

Error: self signed certificate
    at TLSSocket.onConnectSecure (_tls_wrap.js:1049:34)
    at TLSSocket.emit (events.js:182:13)
    at TLSSocket._finishInit (_tls_wrap.js:631:8)
Emitted 'error' event at:
    at ClientRequest.req.on (/home/project/node_modules/ws/lib/websocket.js:554:15)
    at ClientRequest.emit (events.js:182:13)
    at TLSSocket.socketErrorListener (_http_client.js:391:9)

    at emitErrorAndCloseNT (internal/streams/destroy.js:50:3)
    at process._tickCallback (internal/process/next_tick.js:63:19)

Answer 1

可能您需要一些版本选项。 我用于自签名证书 tthis 选项。 试试看嘛。

var WebSocket = require('ws');
var options = {
    ssl: true,
    rejectUnauthorized: false,
    protocolVersion: 8,
    handshakeTimeout: 60000
};
var webSocket = new WebSocket('wss://localhost:8443/cart', options);

Answer 2

const ws = new WebSocket('wss://localhost:8443/cart', { rejectUnauthorized: false });

这有效
