Question

我正在尝试将cur列表作为数据发送。

当我尝试通过bash变量解析数据时，Curl在数据字段中添加了空对象（这里是$ ips）。它在没有使用变量的情况下工作正常，但是，我需要使用它，因为IP的数量不是常数。以下是与输出一起使用的确切命令/语法：

mabosvgori-m2:Qualys_Auth_Scan vgori$ ips=`cat PRIVATE_IPs`
mabosvgori-m2:Qualys_Auth_Scan vgori$ echo "$ips"
["XX.XX.XX.XX", "YY.YY.YY.YY", "ZZ.ZZ.ZZ.ZZ",....]
mabosvgori-m2:Qualys_Auth_Scan vgori$ curl -v -H "Content-Type:application/json" -X "POST" -d "$ips" "https://aa.bb.info/TEST/APP/Scan" --trace-ascii /dev/stdout
Warning: --trace-ascii overrides an earlier trace/verbose option

我不能使用--data-urlencode或任何其他编码选项，因为服务器脚本不支持这些选项。

Answer 1

我真的认为它是curl，但我认为它是cat，这是罪魁祸首。

使用cat PRIVATE_IPs | tr -dc '[:digit:],."[]'解决了这个问题。

Answer 2

再次错了。我终于认为它是IP地址中的空字节本身就是问题所在。也就是说，如果IP地址包含XX.YY.100.ZZ之类的内容，则会抛出此错误。

curl通过bash变量解析时，curl在数据字段中发送空对象
