laravel10接入支付宝支付alipaysdk/openapi问题Class "AlipayTradePagePayRequest" not found

这是因为v2版本的sdk是没有命名空间，composer无法正常导入，

解决方法：修改composer.json

"autoload": {
        "psr-4": {
            "App\\": "app/",
            "Database\\Factories\\": "database/factories/",
            "Database\\Seeders\\": "database/seeders/"
        },
        "classmap": [
            "vendor/alipaysdk/openapi/v2/aop"
        ]
    },

然后，运行composer dumpautoload，即可正常运行。
