Curl
wget: 伺服器返回錯誤: HTTP/1.1 401 Unauthorized from BusyBox
我知道應該在軸開發人員社區論壇上提出 Axis 相機 API 特定問題，但是這個問題對於 http 網路訪問來說似乎是通用的，所以試圖在這裡獲得一些幫助
我將 Axis IP 攝影機連接到本地網路。我在通過 BusyBox 中的 wget/curl 命令訪問相機 API 時遇到問題（同一本地網路中的嵌入式板）
從視窗 cygwin 的 wget 命令通過其 API 訪問相機時，它給了我有效的響應：
admin@LAPTOP /cygdrive/c/axis $ wget -O imageformat.txt 'http://root:pass@192.168.0.90/axis-cgi/param.cgi?action=list&group=Properties.Image.Format' --2021-06-30 11:13:07-- http://root:*password*@192.168.0.90/axis-cgi/param.cgi?action=list&group=Properties.Image.Format Connecting to 192.168.0.90:80... connected.

Version on windows machine: admin@LAPTOP /cygdrive/c/axis $ wget --version GNU Wget 1.21.1 built on cygwin. Version on busybox machine: root@admin:~# wget BusyBox v1.24.1 (2019-02-19 13:37:55 IST) multi-call binary.
因此，如果有一天它可以幫助某人，我將發布自己查詢的答案…
wget（v1.18）附帶busybox（v1.24.1）不是全功能的wget，它安裝了最少的開關，所以將wget配方更新到v1.21.1解決了這個問題。
