Im am trying to implement push integration using php and native zmq. I have successfully send send my message to server, but my problem is I cannot push the message to browser using js Websocket().

我正在尝试使用PHP和原生zmq实现推送集成。 我已经成功发送我的消息发送到服务器,但我的问题是我无法使用js Websocket()将消息推送到浏览器。 我说WebSocket连接到'ws://127.0.0.1:8080 /'失败:在WebSocket握手期间出错:无效的状态行 这里是我的客户端代码: <?php try { function send($data) { $context = new ZMQContext(); $push = new ZMQSocket($context, ZMQ::SOCKET_PUSH);
I have something similar to this: var a = (function () { return { b: 1, c: function () { console.log(this.b); } }; })(); So, a.c(); // = 1 But if I do b = 2; a.c.apply(this); // = 2 Is it possible to preserve the context of "this" inside "ac()" without changing (too much) the structure of "a" object? I don't h
我有类似的东西: var a = (function () { return { b: 1, c: function () { console.log(this.b); } }; })(); 所以, a.c(); // = 1 但如果我这样做 b = 2; a.c.apply(this); // = 2 是否可以在“ac()”内部保留“this”的上下文而不改变(太多)“a”对象的结构? 我没有控制函数的调用,所以我需要一个解决方法来处理这个对象本身。 更新 : 更具体地说,这是我的文件
Is it possible to inject dependencies into ES2015 modules like in other programming languages like C# or Java? If I import a module I create a hard dependency to it and can not change it later at runtime. For example I have following JavaScript code: import Animal from './dog'; class Person { feedAnimal() { new Animal().feed(); } } I am importing the dog module. But what if I want t
是否有可能将依赖关系注入ES2015模块,如其他编程语言(如C#或Java)? 如果我导入一个模块,我创建一个硬依赖关系,并且不能在运行时稍后改变它。 例如,我有以下JavaScript代码: import Animal from './dog'; class Person { feedAnimal() { new Animal().feed(); } } 我正在导入狗模块。 但是如果我想把它改成猫呢? 目前我必须手动修改第1行,但在某些情况下,我希望可以从外部对其进行配置,以便在某些情

Tech: WebGL / GL When I render 10k sprites (using spritebatch) immediately into back buffer everything is ok. 10k When I render it into render texture I gets some strange problem with alpha blending (I guess..). In places where texture has transparent pixels the alpha is calculated wrongly (IMO it should be cumulative). 10k 1k 200 with black background Blend config: gl.enable(gl.B
Tech:WebGL / GL 当我将10k精灵(使用spritebatch)立即渲染到后台缓冲区时,一切都很好。 10K 当我把它渲染成渲染纹理时,我得到了一些奇怪的问题与alpha混合(我想..)。 在纹理具有透明像素的地方,alpha的计算错误(IMO应该是累积的)。 10K 1K 200与黑背景 混合配置: gl.enable(gl.BLEND); gl.blendEquation(gl.FUNC_ADD); gl.blendFunc(gl.SRC_ALPHA, gl.ONE_MINUS_SRC_ALPHA); 这是我如何创建渲染缓冲
