func NewClient

func NewClient(merchantId, serialNumber, appSecret, certFile, keyFile string) (cli *Client, err error)

实例化一个客户端

func (*Client) DoGet

func (cli *Client) DoGet(url string, needVerify ...bool) (resp []byte, err error)

GET一个API

func (*Client) DoPost

func (cli *Client) DoPost(url, body string, needVerify ...bool) (resp []byte, httpCode int, err error)

POST一个API

func (*Client) GetWechatCertificate

func (cli *Client) GetWechatCertificate() (err error)

获取微信支付平台证书 平台证书会周期性更换。建议商户定时通过API下载新的证书 可以弄个Cronjob线程周期执行这个方法
