问题简述：aliyunmq/mq-http-sdk 最新版1.0.1 内部依赖问题导致的服务异常情况处理

目前使用的是aliyunmq/mq-http-sdk最新版1.0.1 依赖包 guzzlehttp/guzzle: >=6.0.0 https://packagist.org/packages/aliyunmq/mq-http-sdk 1.0.1 requires php: >=5.5.0 guzzlehttp/guzzle: >=6.0.0

但目前 guzzlehttp/guzzle 最新版是 7.2.0 https://packagist.org/packages/guzzlehttp/guzzle 7.2.0 requires php: ^7.2.5 || ^8.0 ext-json: * guzzlehttp/promises: ^1.4 guzzlehttp/psr7: ^1.7 psr/http-client: ^1.0

aliyunmq/mq-http-sdk composer.json { "name": "aliyunmq/mq-http-sdk", "type": "library", "description": "Aliyun Message Queue(MQ) Http PHP SDK, PHP>=5.5.0", "keywords": ["Aliyun","Alicloud", "MQ", "Message Queue", "Message", "Queue"], "homepage": "https://github.com/aliyunmq/mq-http-php-sdk", "license": "MIT", "require": { "php": ">=5.5.0", "guzzlehttp/guzzle": ">=6.0.0" }, "repositories": { "packagist": { "type": "composer", "url": "https://packagist.phpcomposer.com" } }, "autoload":{ "psr-4": { "MQ\\": "MQ/" } } }

aliyunmq/mq-http-sdk 1.0.1 不兼容 7.2.0 错误日志： [2020-10-16 16:27:28] production.ERROR: Symfony\Component\Debug\Exception\FatalThrowableError: Undefined class constant 'VERSION' in /data/op_db/vendor/aliyunmq/mq-http-sdk/MQ/Http/HttpClient.php:50

解决方法：

根据错误提示找到那一行： $this->agent = "mq-php-sdk/1.0.1(GuzzleHttp/" . \GuzzleHttp\Client::VERSION . " PHP/" . PHP_VERSION . ")"; 修改为： $this->agent = "mq-php-sdk/1.0.1(GuzzleHttp/" . \GuzzleHttp\Client::MAJOR_VERSION . " PHP/" . PHP_VERSION . ")";
