使用pm2部署Express应用程序

数据库是mongodb

使用命令运行app时:

NODE_ENV=production pm2 start app.js -i max

aften有错误:绑定EADDRINUSE,这是日志,当出错时,

枚举定义在 OrderTypesEnum.gql

enum OrderTypes {
  full_buy
  pink_buy
}

导入 OrderTypesEnum.gql 文件

import OrderTypes from '@/graphql/OrderTypesEnum.gql'`

但是，如何在代码中获取枚举？

我使用OrderTypes.full_buy 得到一些错误：

   self.$apollo.mutate({
        mutation: createOrder,
        variables: {
          subjectId: self.subject.id,
          types: OrderTypes.full_buy
        }
      })

Mutation createOrderMutation error: Invariant Violation: Schema type definitions not allowed in queries. Found: "EnumTypeDefinition"

OrderTypes 类型枚举的检查

venv ? which pg_config

例如:

我有一个二进制看起来像这样:

 bin1 = "2\nok\n3\nbcd\n\n"?

要么

 bin2 = "2\nok\n3\nbcd\n1\na\n\n"?

等等...

格式是

 byte_size  \n  bytes \n byte_size  \n  bytes \n  \n 

我想要解析二进制获取

  ["ok", "bcd"]

如何在Elixir或Erlang中实现？

去版本

Go版本解析了这个

func (c *Client) parse() []string {
    resp := []string{}
    buf := c.recv_buf.Bytes()
    var idx, offset int
    idx = 0
    offset = 0

    for {
        idx = bytes.IndexByte(buf[offset:], '\n')
        if idx == -1 {
            break
        }
        p := buf[offset : offset+idx]
        offset += idx + 1
        //fmt.Printf("> [%s]\n", p);
        if len(p) == 0 || (len(p) …
