请教关于EG91模快使用AT指令透过HTTP 并附加头请求进行 POST图片

我需要使用头请求后,再使用POST将图片上传到伺服器。
目前从官方curl的指令中只有主机位置:
https://staging.nordicgamekeeper.com/api/partner/v1/hardware/camera/89332401000017638129/image
和一个头请求:
Authorization: Basic a2luZ2hhdDplMnQwbjl0MHkzYjJvNGEwejdtOG80ZjB6M2sxejFiNQ’
下面是我使用EG91下AT命令
AT+QHTTPCFG=“contextid”,1

OK
AT+QHTTPCFG=“requestheader”,1

OK
AT+QHTTPCFG=“responseheader”,1

OK
AT+QHTTPCFG=“custom_header”,“Post /api/partner/v1/hardware/camera/89332401000017638129/image HTTP/1.1Host: staging.nordicgamekeeper.comAuthorization: Basic a2luZ2hhdDplMnQwbjl0MHkzYjJvNGEwejdtOG80ZjB6M2sxejFiNQContent-Type: application/json;charset=utf-8Content-Length: 72”
