【问题描述】：
我正在尝试使用 Paypal 沙盒从 localhost 测试我的 Paypal 集成，但每当我尝试从 Paypal 获取访问令牌时，都会返回以下错误：
{
"error": "invalid_client",
"error_description": "Client Authentication failed"
}
我用 curl 提出请求：
curl -v https://api.sandbox.paypal.com/v1/oauth2/token \
-H "Accept: application/json" \
-H "Accept-Language: en_US" \
-u "clientId:secret" \
-d "grant_type=client_credentials"
显然我在请求中使用了实际的客户端 ID 和密码，并且我确定我在沙盒环境中使用了正确的客户端 ID 和密码（我仔细检查了）。
Curl 的详细日志如下所示：
curl -v https://api.sandbox.paypal.com/v1/oauth2/token \
> -H "Accept: application/json" \
> -H "Accept-Language: en_US" \
-u "clientId:secret" \
> -d "grant_type=client_credentials"

问题似乎出在这里：
ALPN, server did not agree to a protocol
我不知道这意味着什么。这可能与我从 localhost 进行测试的事实有关吗？我该如何解决这个问题？

不不，我改了。原始日志中包含实际的 clientId。
