Question

WebSocket可以选择向请求添加标题，但您无法向其添加SecurityContext。 SecureSocket具有SecurityContext，因此我可以添加ssl证书但不能添加标头。对此有何想法？

更新我试图用SecurityContext对象创建一个websocket 因为我无法访问基础HttpClient，所以我试图使用 runZoned方法

 int i = 0;
  socket = await io.HttpOverrides.runZoned<Future<io.WebSocket>>(
  () => io.WebSocket.connect(uri, headers: headers),
  createHttpClient: (io.SecurityContext securityContext) {
    log.w('creating HttpClient ${i++}');
    return new io.HttpClient(context: options.securityContext);
  },
);

createHttpClient被调用大约3550次然后没有任何事情发生

它应该非常简单，因为websocket httpclient就在那里

Answer 1

解决方案是传递SecureSocket以创建WebSocket。

示例：

SecureSocket socket = await SecureSocket.connect("host", port);
WebSocket ws = new WebSocket.fromUpgradedSocket(socket);

希望有所帮助！

Answer 2

尝试

class MyHttpOverrides extends HttpOverrides {
  @override
  HttpClient createHttpClient(SecurityContext context) {
    return super.createHttpClient(context)
      ..badCertificateCallback =
          (X509Certificate cert, String host, int port) => true;
  }
}


// Run this code in main function
HttpOverrides.global = new MyHttpOverrides();

将标头添加到SecureSpocket或SecurityContext到WebSpcket
