Java 推送程序无效签名：应为的HMAC SHA256十六进制摘要,java,javascript,pusher,Java,Javascript,Pusher,我在一个HTML文件中有JavaScript代码，从中调用服务器进行身份验证： <html> <script> <head> var options = { authEndpoint: "api/pusher.json?socket_id=9900&channel_name=presence-channel" } var pusher = new Pusher('98384343434343434', options); pus

我在一个HTML文件中有JavaScript代码，从中调用服务器进行身份验证：

<html>
<script>
<head>
    var options = { authEndpoint: "api/pusher.json?socket_id=9900&channel_name=presence-channel" }
    var pusher = new Pusher('98384343434343434', options);
    pusher.connection.bind('connected', function() {
        console.log("connected");
        socketId = pusher.connection.socket_id;
        console.log("socketId" + socketId);
    });

    var channel = pusher.subscribe('presence-channel');
</script>
</head>
<body></body>
</html>

从pusher.authenticate返回的

authBody

应该为您提供响应客户端请求所需的一切。您只需要确保

sendDataResponse

将

authBody

作为JSON作为响应的主体发送回来

我已经更新了您提供的示例，以删除不需要的行：

@Path("/api/pusher")
public class PusherAction extends BusinessApiAction {
    @POST

    @Produces({ "application/Json", "application/xml" })
    public Response pusher(@Context ServletContext context, @Context HttpServletRequest req, @Context HttpServletResponse res, @FormParam("socket_id") String socketId, @FormParam("channel_name") String channelName) throws Exception {
        System.out.println("\n\n===channel==> " + channelName + "\t socket id-->" + socketId);

        Pusher pusher = new Pusher(APP_ID, APP_KEY, APP_SECRET);
        String userId = "5433d5da97d88628ec000300";
        Map<String, String> userInfo = new HashMap<>();
        userInfo.put("name", "Phil Leggetter");

        String authBody = pusher.authenticate(socketId, channelName, new PresenceUser(userId, userInfo));

        return sendDataResponse(authBody);
    }

}

@Path（“/api/pusher”）

userInfo.put（“name”，“Phil Leggetter”）；
字符串authBody=pusher.authenticate（socketId，channelName，newpresenceuser（userId，userInfo））；
返回sendDataResponse（authBody）；
}
}

pusher rest java库自述文件显示了不需要的附加功能：

感谢@leggetter的回复，我尝试使用var options={authEndpoint:“api/pusher.json”}；但是我得到了错误参数[socketId]不应该为null。我遗漏了什么吗？应该是

socket\u id

，而不是

socketId

@Kamini你能更新这个问题，提供更多关于

pusher.json

处理代码的信息吗？e、 g.获取查询参数。@Kamini太棒了！你能把我的回答标记为答案吗？我只是想知道客户端对客户端的通信，现在每当我在服务器api/pusher Result=pusher.trigger（channelName，“client event”，authBody）中编写时，我就有2个html文件；并在client1.html中编写channel.bind（'client-event'，函数（data）{alert（“来自服务器api的数据-->”+数据）；}）；在这里，无论authbody发送什么数据，我都得到了警报，但我希望它通过客户端到客户端的通信来完成，我尝试在一个client2.html通道中使用触发器（'client-event'，{data:'hello client1'}）；但是没有在其他client1.html中获得警报，在那里我绑定了事件您已经共享了上面的应用程序机密。请确保在Pusher仪表板中重置应用程序机密，好吗？您可以从应用程序密钥->应用程序凭据部分执行此操作。
