Functions

func CheckErr

func CheckErr(err error)

CheckErr error

func DisableThroughLogFilter

func DisableThroughLogFilter(ctx context.Context) context.Context

DisableThroughLogFilter 将LogFilterTag设置到context中，用于跨服务传递

func ExtractCallThroughMethod

func ExtractCallThroughMethod(ctx context.Context) string

ExtractCallThroughMethod ctx获取到上游接口名

func ExtractRequestAttr

func ExtractRequestAttr(ctx context.Context, key string) (value string, ok bool)

ExtractRequestAttr 将context中的metadata中的key-value提取出来

func ExtractServiceMethod

func ExtractServiceMethod(ctx context.Context) string

ExtractServiceMethod ctx获取到上游接口名

func FlatMap2Array

func FlatMap2Array(params map[string]interface{}) []interface{}

FlatMap2Array 将map转化为key-value数组
