Functions

func WithCancel

func WithCancel(parent context.Context) (IContext, CancelFunc)

func WithContext

func WithTimeout

func WithTimeout(goctx context.Context, d time.Duration) (IContext, CancelFunc)

Types

type CancelFunc

type CancelFunc = context.CancelFunc

type Context

type Context = IContext

type IContext

type IContext interface {
	context.Context
	Set(key string, value interface{})
	// SetMeta与Set的区别是 SetMeta设置的key在ctx.GetHeaderMap()时会返回
	// 而这个map通常是ddns client请求别的服务时需要透传过去的Header
	// 故如果你觉得这个key需要进行透传，请用SetMeta
	SetMeta(key string, value string)
	WithValue(key interface{}, val interface{}) IContext
	WithCancel() (IContext, CancelFunc)
	WithTimeout(d time.Duration) (IContext, CancelFunc)

	GetHeaders() http.Header

	Get(key string) (value interface{}, exists bool)

	GetString(key string) (v string)
	GetInt64(key string) (i int64)
	GetInt(key string) (i int)

	GetGoContext() context.Context
	GetAllKey() map[string]interface{}
	GetHttpRequest() *http.Request
	LogInfo(msg string, fields ...log.Field)
	LogError(msg string, fields ...log.Field)
}
