如何在WebSocket中代理到多个服务器

由 发布于

我在芭蕾舞女演员中编程了一个代理，该代理从用户接收对Web套接字的请求，并通过另一个Web套接字将其发送到处理该请求的服务。当前，当服务向我发送响应时，芭蕾舞女演员脚本将该响应返回给用户。我希望在收到服务响应后将其发送到另一个服务，以执行第二次处理，并且当该服务响应并将其返回给用户时，我想这样做。

我有以下代码：

import ballerina/http;
import ballerina/log;


final string ASSOCIATED_CONNECTION = "EXTRACTOR CONNECTION";
final string EXTRACTOR = "ws://192.168.10.248:8081";



@http:WebSocketServiceConfig {
    path: "/api/ws"
}

service RequestService on new http:Listener(9091) {

  resource function onOpen(http:WebSocketCaller caller) {

        http:WebSocketClient wsClientEp = new(
            EXTRACTOR,
            {callbackService: ClientService,
            readyOnConnect: false,
            maxFrameSize: 2147483648
        });

        wsClientEp.setAttribute(ASSOCIATED_CONNECTION, caller);
        caller.setAttribute(ASSOCIATED_CONNECTION, wsClientEp);

        var err = wsClientEp->ready();
        if (err is http:WebSocketError) {
            log:printError("Error calling ready on client", err);
        }
    }

    resource function onText(http:WebSocketCaller caller, string text, boolean finalFrame) {

        http:WebSocketClient clientEp = getAssociatedClientEndpoint(caller);
        var err = clientEp->pushText(text, finalFrame);
        if (err is http:WebSocketError) {
            log:printError("Error occurred when sending text message", err);
        }
    }


    resource function onError(http:WebSocketCaller caller, error err) {

       http:WebSocketClient clientEp = getAssociatedClientEndpoint(caller);
       var e = clientEp->close(statusCode = 1011, reason = "Unexpected condition");
       if (e is http:WebSocketError) {
           log:printError("Error occurred when closing the connection", e);
       }
       _ = caller.removeAttribute(ASSOCIATED_CONNECTION);
       log:printError("Unexpected error hence closing the connection", err);
   }

   resource function onClose(http:WebSocketCaller caller, int statusCode, string reason) {

       http:WebSocketClient clientEp = getAssociatedClientEndpoint(caller);
       var err = clientEp->close(statusCode = statusCode, reason = reason);
       if (err is http:WebSocketError) {
           log:printError("Error occurred when closing the connection", err);
       }
       _ = caller.removeAttribute(ASSOCIATED_CONNECTION);
   }
}

service ClientService = @http:WebSocketServiceConfig {} service {

    resource function onText(http:WebSocketClient caller, string text, boolean finalFrame) {
        http:WebSocketCaller serverEp = getAssociatedServerEndpoint(caller);
        var err = serverEp->pushText(text, finalFrame);
        if (err is http:WebSocketError) {
            log:printError("Error occurred when sending text message", err);
        }
    }

    resource function onError(http:WebSocketClient caller, error err) {
        http:WebSocketCaller serverEp = getAssociatedServerEndpoint(caller);
        var e = serverEp->close(statusCode = 1011, reason = "Unexpected condition");
        if (e is http:WebSocketError) {
            log:printError("Error occurred when closing the connection", err = e);
        }
        _ = caller.removeAttribute(ASSOCIATED_CONNECTION);
        log:printError("Unexpected error hense closing the connection", err);
    }

    resource function onClose(http:WebSocketClient caller, int statusCode, string reason) {
        http:WebSocketCaller serverEp = getAssociatedServerEndpoint(caller);
        var err = serverEp->close(statusCode = statusCode, reason = reason);
            if (err is http:WebSocketError) {
                log:printError("Error occurred when closing the connection", err);
            }
        _ = caller.removeAttribute(ASSOCIATED_CONNECTION);
    }
};

function getAssociatedClientEndpoint(http:WebSocketCaller ep) returns (http:WebSocketClient) {
    http:WebSocketClient wsClient = <http:WebSocketClient>ep.getAttribute(ASSOCIATED_CONNECTION);
    return wsClient;
}

function getAssociatedServerEndpoint(http:WebSocketClient ep) returns (http:WebSocketCaller) {
    http:WebSocketCaller wsEndpoint = <http:WebSocketCaller>ep.getAttribute(ASSOCIATED_CONNECTION);
    return wsEndpoint;
}

我做了以下管道： 客户端->芭蕾舞女演员代理->服务1->芭蕾舞女演员代理->客户端

我想要： 客户端->芭蕾舞女演员代理->服务1->芭蕾舞女演员代理->服务2->芭蕾舞女演员代理->客户端
