func Test() (core.Client,error) {
client, err := ecommerce.NewClient(&core.ClientConf{

ApiV3Key: "${APIKEY}",
ApiCert: &core.ApiCert{
ApiSerialNo: "${APISerialNo}",

// 该项是可选项，获取平台证书前可不填
PlatCert: &core.PlatformCert{
PlatformSerialNo: "${PlatformSerialNo}",
PlatformCertKey: "${platformPublicCert}",
},
HttpClient: nil,
})
if err != nil {
return nil, err
}
return client, nil
