微信版本号是1.0.5 ，sdk 版本是 "@tencent/wechat_open_sdk": "1.0.11"

let fileObject = new WXFileObject()

fileObject.fileUri = UrlUtils.getUriFromPath(path)

let mediaMessage = new wxopensdk.WXMediaMessage()

mediaMessage.title = FileUtils.getFileName(path)

mediaMessage.mediaObject = fileObject

let req = new wxopensdk.SendMessageToWXReq()

req.scene = wxopensdk.SendMessageToWXReq.WXSceneSession

req.message = mediaMessage

WechatUtils.getWechatAPI().sendReq(getContext(this) as common.UIAbilityContext, req)
