小编ana*_*dan的帖子

有没有谷歌和解决方案是在apache中使用iptables或mod重定向？由于我的应用程序使用websockets,上面的解决方案破坏了我的websocket连接,我再次使用端口8080连接到我的websockets.有没有办法可以在端口80上运行glassfish本身,这样我的websockets也可以在端口80上运行更容易对于公司防火墙后面的用户访问应用程序,因为corparates可能阻止8080.

我也有root访问权限.

默认情况下,如果未指定,则docker使用shm大小为64m,但可以使用--shm-size = 256m在docker中增加

我应该如何增加kuberenetes容器的shm大小或在kuberenetes中使用--shm-size of docker.

我试图在打字稿中使用生成器函数.但编译器会抛出错误

error TS2339: Property 'next' does not exist on type

下面是我最接近的代码示例.

export default class GeneratorClass {
    constructor() {
        this.generator(10);
        this.generator.next();
    }
    *generator(count:number): Iterable<number | undefined> {
        while(true)
            yield count++;
    }   
}

这是同一个游乐场的链接

是什么KineticJS方法之间的区别layer.draw(),layer.drawScene()以及layer.drawHit()？

我正在尝试在我的vps中创建一个oracle xe数据库.

VPS OS:Cent OS.

当试图运行

/etc/init.d/oracle-xe configure

它会引发错误数据库容错失败并检查日志但日志只显示ORA-01034:ORACLE不可用

以下是历史......

我正在尝试用spring创建一个websocket端点.但每当我尝试从客户端连接时,我得到404.我也有一个Java实现

@ServerEndpoint(value = "/websocket")

这很好用.下面是我的spring实现的代码,它不起作用.我在这做错了什么？

package com.tlab.endpoint;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.WebSocketHandler;
import org.springframework.web.socket.config.annotation.EnableWebSocket;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;

@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(socketHandler(),"/socket");;
    }

    @Bean
    public WebSocketHandler socketHandler() {
        return new SocketHandler();
    }

}

下面是处理程序

package com.tlab.endpoint;

import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.handler.TextWebSocketHandler;


public class SocketHandler extends TextWebSocketHandler {

    @Override
    public void handleTextMessage(WebSocketSession session, TextMessage message) {

    }

}

在客户端代码我尝试了所有diff可能的组合

在处理程序中使用/ socket

var websocket = new WebSocket("ws://localhost:8080/tsim/socket");
var websocket …

1)是否有任何摘要完成事件,我可以用它来更新我的画布.我有一个角度应用程序,它具有画布对象的不同属性的视图.每当我更改属性时,一旦摘要完成,如果我可以获得摘要完成事件,我可以更新画布(使用kineticJs)重绘具有最新属性的图表.

目前我正在从视图中调用方法

2)我只是在打开对象设置时使用视图并将其路由到新视图.在这种情况下,网址也随着网页/ #view而改变.它只是弹出窗口,我不需要页面末尾的#view,但仍然使用路由和视图概念.还有别的吗？

我试图通过websocket发送使用协议缓冲区编码的二进制消息.我能够使用Glassfish 4.0成功发送.但是相同的代码在tomcat 8中失败,下面有例外.

无法使用角度js ng-style指令设置渐变..能够通过使用下面设置正常颜色

<span ng-style="{'background-color': slidercolor}">works</span>

但对于渐变它不起作用

下面是相同的jsfiddle.

<span ng-style="{'background-color':'-webkit-gradient(linear, left top, right top, color-    stop(0%,'slidercolor'), color-stop(100%,rgba(125,185,232,0)))'}">didnt work</span>

另外请告诉我哪些应该用引号括起来,哪些不应该...
