Python 請求適用於 PowerShell，但不適用於 WSL

Question

我正在嘗試執行：

r = requests.post( url, headers=headers, data = payload, cert=(ca_cert,ca_key))

在 PowerShell 中它可以工作，但是當我嘗試使用 WSL 時，我得到：

   Traceback (most recent call last):

這是DNS的問題。 我修復它在 WSL 上運行此功能：

vpn() {
[ -s /run/resolvconf/resolv.conf -a -L /etc/resolv.conf ] && sudo cp --remove-destination /run/resolvconf/resolv.conf /etc/resolv.conf
local sudo="sudo"
if [ -w /etc/resolv.conf ]; then sudo=""; fi
$sudo ed -s /etc/resolv.conf <<'EOF'
H
a
#EOF
.
kx
g/^nameserver /d
.-1r !/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe -Command '$x = Get-NetAdapter | Group-Object -AsHashtable -Property ifIndex; Get-DnsClientServerAddress -AddressFamily ipv4 | where {$x[$_.InterfaceIndex].Status -eq "Up"} | Select-Object -ExpandProperty ServerAddresses | foreach {"nameserver " + $_}' | sed 's/\r//g'

wq
EOF
}
