基于 Guzzle, PHP HTTP client 实现请求时，当响应非 20x 时，无法获取到 $response 变量

1、基于 Guzzle, PHP HTTP client 实现请求时，当响应非 20x 时，无法获取到 $response 变量。如图1

$response = $this->client->request('POST', $this->nlsApiUrl, [
	'json' => array_merge($input, [
		'appkey' => $this->nlsAppKey,
		'token' => $token
	])
]);

        ]
    }
}

2、现阶段需要针对 响应中的字段 status 的值进行判断，以做后续的逻辑处理。参考：https://docs.guzzlephp.org/en/stable/request-options.html#http-errors 。设置成 false 来禁用HTTP协议抛出的异常(如 4xx 和 5xx 响应)，默认情况下HTPP协议出错时会抛出异常。调整代码如下

$response = $this->client->request('POST', $this->nlsApiUrl, [
	'json' => array_merge($input, [
		'appkey' => $this->nlsAppKey,
		'token' => '39f03ee9a79445d4b2f714b61227b388'
	]),
	'http_errors' => false
]);

$contents = $response->getBody()->getContents();

print_r($contents);exit;

3、当服务端响应 400 时，不再抛出异常 GuzzleHttp\Exception\ServerException。符合预期。如图2
