gunicorn + Nginx

uwsgi + Nginx

• 问题1：uwsgi的默认监听进程的数量100
  

  解决： 之前由于只知道启动uwsgi worker的数量，不管怎么调worker的数量，并发都很低，
  配置listen参数解决，根据服务器配置和访问来决定，目前我开的是20000

• 问题2：supervisor没有办法优雅的重启uwsgi worker，导致服务器资源被重启的uwsgi进程占满
  

  解决：配置no-orphans参数

• 配置范例
  

  master = true
  processes = 8
  thread = 100
  thread-stacksize = 512
  stats = 127.0.0.1:9194
  buffer-size = 65535
  enable-threads = true
  http-timeout = 60
  socket-timeout = 60
  chmod-socket = 666
  harakiri = 60
  max-requests = 20000
  listen = 20000
  no-orphans

获取PID和32位KEY

使用该接口

• 使用该接口需要实现两个工具函数:
  
  1. 构造支付宝的支付链接，如果链接请求成功会生存支付宝的支付页面。
  2. 支付成功后需要验证支付宝返回的结果是否正确，如果正确就做相应的订单更新。
• 实现构造支付链接
  

  注意事项：

  1. 传给支付宝的url参数需要字母顺序排序，且不能含有空格，空值。
  2. 验证，使用MD5验证，构造除了sign和sign_type的url参数和key做md5。
• 实现验证支付宝返回数据的验证
  

  验证支付宝请求return_url和notify_url的数据
  注意事项

  1. 支付宝的notify_id在一分钟后会实效。
  2. 支付宝异步请求如果没有收到success的话会间隔发请求，直到获取到success，或者超过24小时。

  代码： 一个配置类AlipayConfig
  一个工具类AlipayUtils
  

  AlipayConfig代码：
