我想听听各位如果现在新建一个项目，要不要做成单页

Ruby on rials?

是端口没映射

ports:
  - "80:80"
  - "3002:3002"

现在就差最后一步了，结果出来这么个报错NoMethodError (private methodwarn' called for nil:NilClass):`

现在 nginx 也生效了，我想试着绑在 3002 端口下看下效果，但是并没有反应，80 端口是好的

nginx

upstream bkfix {
    server bkfix:7000 fail_timeout=0;
  }

  server {
    listen 3002 default_server;

    root /var/www/bkfix/public;
    location ^~ /assets/ {
      gzip_static on;
      expires max;
      add_header Cache-Control public;
    }

docker-compose

    volumes:

我想让我的 nginx.conf 生效，但是我 nginx 只要加上command: nginx -c /etc/nginx/nginx.conf跑就会直接退出，不知道怎么回事，

我还想问下各位大佬，如果想用 docker 来部署 production，正确的流程应该是怎么样的，本地 Build 完，传上去，到服务器 Pull 下来跑，还是到服务器上 build，感觉比起一句mina deploy来说，docker 部署步骤还挺多的

现在又碰到一个问题，我 link 了一个 redis，但是我的 rails 默认找的是 127.0.0.1:6379，而 redis 在另一个容器里面，rails 容器得用 redis:6379 来访问，这个怎么处理比较妥一点

version: '3'
services:
  bkfix:
    build: .
    command: rails s -p 4000
    ports:
      - "3000:4000"
    volumes:
      - .:/app
    links:
      - mysql
      - redis
  mysql:
    image: mysql
    restart: always
    command: --character-set-server=utf8 --collation-server=utf8_general_ci
    ports:
      - '3306:3306'
    environment:
      - MYSQL_ROOT_PASSWORD=ad66544970123
      - MYSQL_DATABASE=bkfix_dev
    volumes:
      - ./data/mysql:/var/lib/mysql
  redis:
    image: redis:alpine
    command: redis-server
    volumes:
      - ./data/redis:/data

这样啊，那数据库呢，装在一起，还是新建一个容器 link

确实是因为服务器上没有application.rb，问题解决了

找到原因了 不是"AES-128-ECB" 是"AES-128-CBC"

顺便贴一下官方的 nodeJs 版本

var crypto = require('crypto')

function WXBizDataCrypt(appId, sessionKey) {
  this.appId = appId
  this.sessionKey = sessionKey
}

WXBizDataCrypt.prototype.decryptData = function (encryptedData, iv) {
  // base64 decode
  var sessionKey = new Buffer(this.sessionKey, 'base64')
  encryptedData = new Buffer(encryptedData, 'base64')
  iv = new Buffer(iv, 'base64')

  try {
     // 解密
    var decipher = crypto.createDecipheriv('aes-128-cbc', sessionKey, iv)
    // 设置自动 padding 为 true，删除填充补位
    decipher.setAutoPadding(true)
    var decoded = decipher.update(encryptedData, 'binary', 'utf8')
    decoded += decipher.final('utf8')

    decoded = JSON.parse(decoded)

  } catch (err) {
    throw new Error('Illegal Buffer')
  }

  if (decoded.watermark.appid !== this.appId) {
    throw new Error('Illegal Buffer')
  }

  return decoded
}

module.exports = WXBizDataCrypt

我想问下本地开发用 docker，容器外代码改了让容器内的 server 生效呢

加了 i 果然好了。

多谢大佬，话说这个项目就是借鉴了你的https://github.com/rails-engine/exception-track

赶紧把webpacker弄的好用一些才是正道啊

现在的趋势不就是一个网站就一个 tag 吗

target='_blank'

你换中文或者正常的单词试试

你们的网站里面用的都是英文吗，英文也很少有ss这种数据吧

accepts_nested_attributes_for

http://apidocjs.com/

果断升级到 high sierra，好了

dyld: mach-o, but built for simulator (not macOS)
Could not open library 'libfib.dylib': dlopen(libfib.dylib, 5): image not found

为什么我的扩展打不开。 macos 10.12 好像有坑，lz 版本多少

四斋蒸鹅心

把 IP 存起来，丢到 redis?

那那个OPTIONS请求是做什么用的

解决了， 写一个你需要被跨域访问时的OPTIONS路由

routes.rb

match '/api/v1/cards/:id', :controller => 'option_configs', :action => 'options', :via => :options

option_configs_controller.rb

class OptionConfigsController < ApplicationController
  def options
    headers['Access-Control-Allow-Origin'] = "*"
    headers['Access-Control-Allow-Methods'] = 'POST, GET, OPTIONS, PUT'
    headers['Access-Control-Allow-Headers'] = 'Content-Type'
    head :ok
  end
end

Vue 会把 html 文件弄得一团糟，相比 React 的 JSX 来说，Vue 用起来真的不是很舒服

我还以为是我水平不够才觉得难用的，看到管理员说这句话我就放心了。

我临时写了一个比较符合 ES 的

class MyDsl

  def initialize
    @hash = {}
  end

  def method_missing method_name, k=nil, v=nil, &block
    if block_given?
      new_container = self.class.new
      new_container.instance_eval(&block)
      @hash[method_name] = new_container.to_h
    else
      @hash[method_name] ||= {}
      @hash[method_name][k] = v
    end
  end

  def to_h
    @hash
  end
end

es = MyDsl.new
es.bool do
  must do
    match 'title', 'test'
  end
end

es.to_h
=> {:bool=>{:must=>{:match=>{"title"=>"test"}}}}
