以 关闭订单 POST 方法为例：
$promise = $instance
->v3->pay->transactions->outTradeNo->_out_trade_no_->close
->post([
// 请求消息
'json' => ['mchid' => '1xx98216'],
// 变量名 => 变量值
'out_trade_no' => 'O7302615137356d1722326151',
]);
print_r($promise);
实际输出

请求是成功了，只是对GuzzleHttp\Psr7\Response的处理，用print_r是不够的，例如：
<?php print_r( (string) $promise->getBody() );xi详细可阅读： https://docs.guzzlephp.org/en/stable/psr7.html#responses
As described earlier, you can get the body of a response using the
getBody()method.$body = $response->getBody(); echo $body; // Cast to a string: { ... } $body->seek(0); // Rewind the body $body->read(1024); // Read bytes of the body
