我正在尝试在 scala 中执行 curl 命令。curl 命令从 easypost API 获取运费。下面是我正在使用的代码：
import sys.process._
val data="curl -X POST https://api.easypost.com/v2/shipments -u <Easypost Test API Key>: -d 'shipment[to_address][zip]=90277' -d 'shipment[from_address][zip]=94104' -d 'shipment[parcel][length]=20.2' -d 'shipment[parcel][width]=10.9' -d 'shipment[parcel][height]=5' -d 'shipment[parcel][weight]=65.9'".!!
println("Shipping data is "+data)
我正进入（状态 ：
Shipping data is {"error":{"code":"SHIPMENT.INVALID_PARAMS","message":"Unable to create shipment, one or more parameters were invalid.","errors":[]}}
但在终端它的响应如下：

我在这里做错了吗？请建议。
