手动改个版本号解决 $agent .= ' GuzzleHttp/7.0';//.\GuzzleHttp\Client::VERSION;

GuzzleHttp 7版本与6版本有一些Breaking Changes https://github.com/guzzle/guzzle/blob/7.0.0/UPGRADING.md

Constant GuzzleHttp\ClientInterface::VERSION is removed. Added GuzzleHttp\ClientInterface::MAJOR_VERSION instead.

wechatpay-guzzle-middleware这边近期会更新兼容GuzzleHttp 7，在此之前可以将 \GuzzleHttp\Client::VERSION 修改为 \GuzzleHttp\Client::MAJOR_VERSION做临时处理。

GuzzleHttp的引用比较广泛，版本是不可控的

这个地方拼接的内容，意义不是特别大，建议写死吧
