我正在尝试集成 Shippo API 来跟踪我的货件信息a,这是我发送的 CURL 请求
curl https://api.goshippo.com/v1/tracks/ -H "Authorization: ShippoToken <TOKEN>" -H "Content-Type: application/json" -d {"tracking_number":"<TRACKING_NUMBER>"}
但我发送如下回复
{"detail": "JSON parse error - Expecting property name enclosed in double quotes: line 1 column 2 (char 1)"}
谁能告诉我可能出了什么问题。
