javascript - Spring RSocket Security + RSocket-WebSocket-Client(浏览器)

Question

我正在尝试在 Vue 中创建一个站点并在 Spring 上创建后端。我想使用 rsocket 来传输数据，但是只要我在 spring 中添加 rsocket seurity，我就会得到:

'metadata is malformed'

想看看使用 jwt/simpleauth 的工作示例

Answer 1

我用 Simple Auth 解决了这个问题，现在我想将这个授权与 spring websecurity 同步。那些。以便 rsocket 中的路由通过网络安全检查授权。我知道这可以通过 jwt token 实现，即通过 rest 向客户端发送 jwt token ，但我如何在代码中执行此操作？ JS 客户端(浏览器)和 Spring，如何生成 userdetails token ？为了以防万一，我将留下一个简单验证实现的示例:

// METADATA BUILDER
    import {encodeRoute, encodeBearerAuthMetadata, encodeSimpleAuthMetadata, encodeAndAddCustomMetadata, encodeAndAddWellKnownMetadata, MESSAGE_RSOCKET_ROUTING, MESSAGE_RSOCKET_AUTHENTICATION} from "rsocket-core";
    
    export default class Metadata {
        constructor(json) {
            this.route = json['route'];
            this.auth = json['auth'];
        }
    
        toMetadata() {
            let metadata = Buffer.alloc(0);
            if (this.auth) {
                if (this.auth["type"] === 'bearer') {
                    metadata = encodeAndAddCustomMetadata(
                        metadata,
                        MESSAGE_RSOCKET_AUTHENTICATION.string,
                        encodeBearerAuthMetadata(this.auth["token"]),
                    );
                }
                if (this.auth["type"] === 'simple') {
                    metadata = encodeAndAddCustomMetadata(
                        metadata,
                        MESSAGE_RSOCKET_AUTHENTICATION.string,
                        encodeSimpleAuthMetadata(this.auth["username"], this.auth["password"]),
                    );
                }
            }
            if (this.route) {
                metadata = encodeAndAddWellKnownMetadata(
                    metadata,
                    MESSAGE_RSOCKET_ROUTING,
                    encodeRoute(this.route)
                );
            }
            return metadata;
        }
    }

// RSOCKET CLIENT CLASS
    import RSocketWebSocketClient from "rsocket-websocket-client";
    import {BufferEncoders, MESSAGE_RSOCKET_COMPOSITE_METADATA, RSocketClient,toBuffer} from "rsocket-core";
    import Metadata from "./metadata";
    
    
    export default class SpringClient {
        constructor(wsUrl, keepAlive = 60000, lifetime = 180000, dataMimeType = "application/json") {
            this.client = new RSocketClient({

// EXAMPLE, HOW TO USE

    import SpringClient from "./springclient";
    
    this.client = new SpringClient("ws://localhost:7000/", 5000, 15000, "text/plain");
    this.client.connect(
        (socket) => {
            console.log("got connection complete");
            this.socket = socket;
        },
        (error) => {
            console.log("got connection error");
            console.error(error);
        },
        (cancel) => {
            console.log("got connection subscribe");
            /* call cancel() to abort */
        }
    )
    this.client.simpleAuth("LOGIN", "PASSWORD");
    this.client.requestResponse("MESSAGE", "ROUTE",
        (data) => {
            console.log("got response with requestResponse");
            console.log(data.data);
        },
        (error) => {
    
            console.log("got error with requestResponse");
            console.error(error);
        },
        (cancel) => {
            console.log(message);
            /* call cancel() to stop onComplete/onError */
        }
    );
