        public static void AddGrpcScoped<TService>(this IServiceCollection services) where TService : class

              var grpcChannel = GrpcChannel.ForAddress('http://url', new GrpcChannelOptions

使用：

   readonly IProductAppService _productAppService;

   public WeChatController(IProductAppService productAppService)
   { 

      _productAppService = productAppService;

   }


        /// <summary>
        /// 获取一个登录用的qrcode

        /// <returns></returns>
        [Route("test"), AllowAnonymous]
        public async Task<IActionResult> test()
        {
            try
            {
                var model = await _productAppService.GetListAsync();
                return new JsonResult(model);

            } catch (RpcException e)
            {

            }

         }
