Lines 111 to 118 in b7398ef

	$endpoint = $instance->chain('v2/mmpaymkttransfers/promotion/transfers');
	// samples howto control the `HandlerStack`, only effect this request
	$stack = clone $endpoint->getDriver()->select(ClientDecoratorInterface::XML_BASED)->getConfig('handler');
	/** @var HandlerStack $stack */
	$stack->remove('transform_response');
	// yes, start with `@` to prevent the internal `E_USER_DEPRECATED`
	@$endpoint->postAsync(['xml' => [ 'mchid' => $mchid, ], 'handler' => $stack])->then(static function(ResponseInterface $res) {

参考上述测试用例覆盖，用 @$endpoint->postAsync 可屏蔽掉提示。。。
