无参数

## 示例代码

```kotlin
val request = WMPFLaunchWxaAppByQRCodeRequest()
request.baseRequest = WMPFBaseRequestHelper.checked()
request.baseRequest.clientApplicationId = ""
request.rawData = rawData // rawData from qrcode

Log.i(
    TAG, "launchWxaApp: " + "hostAppID = " +
            BuildConfig.HOST_APPID + ", deviceId = " + DeviceInfo.deviceId
)

val result = WMPFIPCInvoker.invokeAsync(
    request,
    IPCInvokerTask_LaunchWxaAppByQrCode::class.java
) { response ->
    if (isSuccess(response)) {
        it.onSuccess(response)
    } else {
        it.onError(TaskErrorException(createTaskError(response)))
    }
}

if (!result) {
    it.onError(Exception("invoke launchWxaAppByScan fail"))
}

// 还可以通过 launchWxaByScanUI 接口实现带有 UI 交互的扫码拉起小程序功能
LaunchWxaAppByScanInvoker.launchWxaByScanUI(this, request)
```
