UPS追踪API未返回postalCode与Weight，请求排查原因

问题背景 #

根据UPS官方文档，调用getSingleTrackResponseUsingGET接口时，响应应包含postalCode（目的地邮编）和Weight（包裹重量）字段，但实际执行请求后，这两个字段并未出现在返回结果中。

实际执行的请求命令 #

curl -i -X GET \
  'https://onlinetools.ups.com/api/track/v1/details/1Z0088XW0360412370?locale=en_US&returnSignature=true' \
  -H 'Authorization: Bearer ......' \
  -H 'Content-Type: application/json' \
  -H 'transId: test123' \
  -H 'transactionSrc: prod'

实际获取的响应内容 #

疑问 #

为什么响应里没有返回postalCode和Weight字段？是不是请求时漏掉了必要的参数？
