安装goex库

go get

go get github.com/nntaoli-project/goex

建议go mod 管理依赖

require (
          github.com/nntaoli-project/goex latest
)

注意事项

  1. 推荐使用GoLand开发。
  2. 推荐关闭自动格式化功能,代码请使用go fmt 格式化.
  3. 不建议对现已存在的文件进行重新格式化，这样会导致commit特别糟糕。
  4. 请用OrderID2这个字段代替OrderID
  5. 请不要使用deprecated关键字标注的方法和字段，后面版本可能随时删除的
