Oauth 2.0 401支付Paypal信用卡时发生未经授权的错误

我想让一个用户接受使用贝宝信用卡付款。因此，我已经从应用程序中授权用户，并按此链接中所述拨打电话

这是我从本地机器发出的卷曲请求

  curl -v https://api.sandbox.paypal.com/v1/payments/payment \

  -H "Content-Type:application/json" \
  -H "Authorization:Bearer 22SKUmLAeeKccfG-FmJdFiT97FLQnjSbeDHDN0hHdEQ" \
  -d '{
        "intent":"sale",
        "payer":{
        "payment_method":"credit_card",
        "funding_instruments":[
         {
           "credit_card":{
             "number":"4417119669820331",
             "type":"visa",
             "expire_month":11,

        "city":"Johnstown",
        "country_code":"US",
        "postal_code":"43210",
        "state":"OH"
      }
    }
  }
]
},
"transactions":[
{
  "amount":{

"total":"7.47",
    "currency":"USD",
    "details":{
      "subtotal":"7.41",
      "tax":"0.03",
      "shipping":"0.03"
    }
  },
  "description":"This is the payment transaction description."
  }
]
}'

我得到一个错误“401未授权”

谁能帮我一下我在上面的电话中遗漏了什么。或者进行信用卡支付需要任何其他范围。

尝试获取新的访问令牌，并将其作为通话的一部分：

401通常意味着您没有正确的访问令牌或它已过期
