Types

type DefaultEncoder

type DefaultEncoder struct {
}

func (*DefaultEncoder) EncodeBytes

func (encoder *DefaultEncoder) EncodeBytes(buffer *bytes.Buffer, data []byte, opts *SignOptions) ([]byte, error)

func (*DefaultEncoder) EncodeValues

func (encoder *DefaultEncoder) EncodeValues(buffer *bytes.Buffer, values url.Values, opts *SignOptions) ([]byte, error)

EncodeValues 1、将参数名及其对应的值进行升序排序 2、将排序后的参数名及参数名使用等号进行连接，例如：a=10 3、将组合之后的参数使用&号进行连接，例如：a=10&b=20&c=30&c=31

type Encoder

type Encoder interface {
