Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

pomelo 客户端的百度小程序实现

安装

npm install pomelo-baidu-client

或者使用单文件版,移步releases

单文件版无需使用 npm,支持 AMD/CMD 等打包方式,可以直接 require

使用

const pomelo = require("pomelo-baidu-client");

// 普通模式,用于生产环境,会生成wss://example.com/ws/3005类似的地址,需要nginx支持
pomelo.init(
  {
    host: host,
    port: port
  },
  function() {
    console.log("success");
  }
);

// 调试模式,用于本地开发,生成普通链接ws://example.com:3005
pomelo.init(
  {
    host: host,
    port: port,
    debugMode: true
  },
  function() {
    console.log("success");
  }
);

// 浏览器调试模式,用于本地开发,使用浏览器原生WebSocket,生成普通链接ws://example.com:3005
pomelo.init(
  {
    host: host,
    port: port,
    debugMode: true,
    browserWS: true
  },
  function() {
    console.log("success");
  }
);

// 如果需要多个连接实例,可以用newInstance方法生成
const pomelo2 = pomelo.newInstance();

具体使用方法见官方的websocket版本客户端说明

额外增加的功能:

全局监听消息(排除已用 request 设置回调的消息)

pomelo.on("onMessage", data => {
  console.log("onMessage", data);
});

特别说明

百度仅支持 wss 连接(https)并且不支持自定义端口号,因此在服务器端进行额外的处理

例如以下代码:

pomelo.init({
  host: "example.com",
  port: 3005
});

实际上连接的是wss://example.com/ws/3005/

需要在服务器端将以上连接转换为ws://example.com:3005

这里提供 nginx 的例子:

server
{
    listen       443 ssl http2 default_server;
    listen       [::]:443 ssl http2 default_server;
    server_name example.com;
    ssl on;
    #证书文件
    ssl_certificate     /etc/ssl/certs/ssl-cert.crt;
    #私钥文件
    ssl_certificate_key /etc/ssl/private/ssl-cert.key;

    ssl_session_timeout 5m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers AESGCM:ALL:!DH:!EXPORT:!RC4:+HIGH:!MEDIUM:!LOW:!aNULL:!eNULL;
    ssl_prefer_server_ciphers on;

    location /ws/3005/ {
        proxy_pass http://127.0.0.1:3005;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
