Php laravel软件包中的paypal_link=null:srmklive/laravel paypal

我对laravel软件包中的paypal_url有一个问题：返回null

我正在使用这个软件包：

这是变量$response的输出：

`array:3 [▼
  "type" => "error"
  "message" => ""
  "paypal_link" => null
]`

以及$provider的另一个输出，返回所有我的配置：

我不知道我做了什么不好，只是我遵循的文件包。但有些事情应该是错的。有人可以帮我吗？

在本地主机上测试签出时，必须将此选项标记为false：

'validate_ssl'   => false

否则它会给你这个错误。

看起来好像某个地方有个错误：“type”=>“error”？这可能就是你没有链接的原因，但我已经设置了返回url和取消url以及相应的url…在本地主机中不起作用，但在服务器上起作用。。。谢谢…我在自适应支付模式下面临同样的问题，成功交易后我什么也得不到。您是否知道中的自适应支付不应在本地主机中。。。应该是在线的，可以上网的。。。
