如何初始化微信服务商模式Client

[rickycoder]

wechat.NewClientV3是否可以直传 appId和mchid，官方的例子只需要appId和 mchid

// NewClientV3 初始化微信客户端 v3
// mchid：商户ID 或者服务商模式的 sp_mchid
// serialNo：商户证书的证书序列号
// apiV3Key：apiV3Key，商户平台获取
// privateKey：私钥 apiclient_key.pem 读取后的内容
client, err = wechat.NewClientV3(MchId, SerialNo, APIv3Key, PrivateKey)
