我试图通过仅提供他们的邮政编码来获取从用户位置到仓库位置的运费。我必须在 scala 中实现它，所以我正在尝试使用他们的 Java API。下面是我正在使用的代码 -

var fromAddressMap:HashMap[String,Object]=new util.HashMap[String,Object]
fromAddressMap.put("zip",warehouse_zip)
var toAddressMap:HashMap[String,Object]=new util.HashMap[String,Object]
toAddressMap.put("zip",user_zip)
var parcelMap:HashMap[String,Object]=new util.HashMap[String,Object]
parcelMap.put("weight", "22")
parcelMap.put("height", "12")
parcelMap.put("width", "8")
parcelMap.put("length", "19")
val fromAddress:Address=Address.create(fromAddressMap)
val toAddress:Address=Address.create(toAddressMap)
val parcel:Parcel = Parcel.create(parcelMap)
val shipmentMap:HashMap[String,Object]=new util.HashMap[String,Object]
shipmentMap.put("to_address",toAddress)
shipmentMap.put("from_address",fromAddress)
shipmentMap.put("parcel", parcel)
val buyCarriers= new util.ArrayList[String]
buyCarriers.add("USPS")
val buyServices= new util.ArrayList[String]
buyServices.add("PriorityMailInternational")
var shipment = Shipment.create(shipmentMap)
shipment = shipment.buy(shipment.lowestRate(buyCarriers, buyServices))
println("Price is "+shipment.prettyPrint())

我得到的只是一个例外：

com.easypost.exception.EasyPostException: Unable to find lowest rate matching required criteria.

我什至尝试使用 curl 命令，例如：

curl -X POST https://api.easypost.com/v2/shipments \
  -u <Easypost api key>: \
  -d 'shipment[to_address][name]=Dr. Steve Brule' \
   -d 'shipment[to_address][street1]=179 N Harbor Dr' \
   -d 'shipment[to_address][city]=Redondo Beach' \
   -d 'shipment[to_address][state]=CA' \
   -d 'shipment[to_address][zip]=90277' \
   -d 'shipment[to_address][country]=US' \
   -d 'shipment[to_address][phone]=8573875756' \
   -d 'shipment[to_address][email]=dr_steve_brule@gmail.com' \
   -d 'shipment[from_address][name]=EasyPost' \
   -d 'shipment[from_address][street1]=417 Montgomery Street' \
   -d 'shipment[from_address][street2]=5th Floor' \
   -d 'shipment[from_address][city]=San Francisco' \
   -d 'shipment[from_address][state]=CA' \
   -d 'shipment[from_address][zip]=94104' \
   -d 'shipment[from_address][country]=US' \
   -d 'shipment[from_address][phone]=4153334445' \
   -d 'shipment[from_address][email]=support@easypost.com' \
   -d 'shipment[parcel][length]=20.2' \
   -d 'shipment[parcel][width]=10.9' \
   -d 'shipment[parcel][height]=5' \
   -d 'shipment[parcel][weight]=65.9'

它在他们的例子中给出。但我收到错误：

curl: (77) error setting certificate verify locations:
  CAfile: /etc/pki/tls/certs/ca-bundle.crt
  CApath: none

知道如何使它工作吗？

我收到了同样的错误，但使用 Java SDK 我getLowestRate()自己实现了一个方法，而不是使用EasyPost这里是一个 java 示例：

Rate selectedRate = null;
for(Rate r : shipment.getRates()) {
  if(selectedRate == null) {
    selectedRate = r;
  }
  if(r.getRate() < selectedRate.getRate()) {
    selectedRate = r;
  }
}

if(selectedRate == null) {
  log.error("Selected rate is null could not find any rates to iteRATE through...");
}

try {
  return shipment.buy(selectedRate);
} catch(EasyPostException e) {
  log.error("Failed to purchase a shipment at the lowest rate for shipment: {}", shipment);
}

正如您的错误消息所述，您的错误似乎是您的系统问题。尝试搜索该错误，可能是如何在尝试访问 HTTPS url 时使用 cURL 处理证书？
