	Key   string
	Debug bool

	TLSClientConfig *tls.Config
}

func NewClient 

func NewClient(mchId, key string) *Client

NewClient creates a new client.

func (*Client) CreateOrder added in v1.1.0 

func (client *Client) CreateOrder(ctx context.Context, req CreateOrderRequest) (*CreateOrderResponse, error)

func (client *Client) MustSetCertificate(certPEM, keyPem string)

MustSetCertificate is like SetCertificate but panics if operation fails.

func (*Client) QueryOrder added in v1.1.0 

func (client *Client) QueryOrder(ctx context.Context, req QueryOrderRequest) (*QueryOrderResponse, error)

QueryOrder gets information of an order by Transaction ID or Trade No.

func (*Client) QueryRefundOrder added in v1.2.0 

func (client *Client) QueryRefundOrder(ctx context.Context, req QueryRefundOrderRequest) (*QueryRefundOrderResponse, error)
