我正在尝试在代理后面的 Windows 上安装 chocolatey:
@powershell -ExecutionPolicy unrestricted
在 power shell 中我正在执行
$wc=new-object net.webclient;
$wc.Proxy=new-object system.net.WebProxy('<myproxy-ip>:8012',$true);
$wc.Proxy.Credentials = new-object system.net.NetworkCredential('<myusername>','<mypass>');
iex ($wc.DownloadString('https://chocolatey.org/install.ps1'));
我收到以下错误
Exception calling "DownloadString" with "1" argument(s): "The remote server returned an error: (407) Proxy Authentication Required."
At line:1 char:1
+ iex ($wc.DownloadString('https://chocolatey.org/install.ps1'));
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : WebException
我使用的用户名/密码与启动 Firefox/iexplorer 时必须输入的用户名/密码相同(见图)。代理没有配置默认用户名/密码,因为我必须始终输入它们。
更多细节(在 Firefox 的私人窗口中使用检查元素)

答案1
看https://github.com/chocolatey/chocolatey/wiki/Proxy-Settings-for-Chocolatey
在 powershell 中定义函数
function Create-Proxy($proxyHost,$proxyPort,$proxyUsername,$proxyPassword){
#$proxy = [System.Net.WebRequest]::GetSystemWebProxy()
$proxyUrl = $proxyHost+":"+$proxyPort;
Write-Host "proxy url [$proxyUrl]";
$proxy = New-Object System.Net.WebProxy($proxyUrl, $true);
$passwd = ConvertTo-SecureString $proxyPassword -AsPlainText -Force; ## Website credentials
$proxy.Credentials = New-Object System.Management.Automation.PSCredential ($proxyUsername, $passwd);
return $proxy;
}
称之为
$wc=new-object net.webclient;
$wc.UseDefaultCredentials = $true
$wc.Proxy = Create-Proxy "<proxy-host>" "<proxy-port>" "<proxy-username>" "<proxy-clear-pass>"
$wc.DownloadString('https://chocolatey.org/install.ps1');
我发现实际的下载有效,但是安装程序的执行却无效,因为它使用了自定义构建的代理。
因此iex ($wc.DownloadString("https://chocolatey.org/install.ps1"));
失败是因为下载的install.ps1

无法测试它(没有可用的类似代理),所以我实际上不知道这是否可行,但您可以尝试以下方法:
$wc = new-object net.webclient;
$proxyUri = new-object system.uri("http://<myproxy-ip>:8012");
$wc.Proxy = new-object system.net.WebProxy($proxyUri, $true);
$cachedCredentials = new-object system.net.CredentialCache;
$netCredential = new-object system.net.NetworkCredential("<myusername>", "<mypass>");
$cachedCredentials.Add($proxyUri, "Basic", $netCredential);
$wc.Proxy.Credentials = $cachedCredentials.GetCredential($proxyUri, "Basic");
iex ($wc.DownloadString("https://chocolatey.org/install.ps1"));
目的是使用 CredentialCache 对象强制凭证使用“基本”身份验证模式。

你可以用这个。对我有用。 https://github.com/chocolatey/choco/wiki/Proxy-Settings-for-Chocolatey
显式代理设置
Chocolatey 从 0.9.9.9 开始明确支持代理。
您只需配置 1 或 3 个设置,Chocolatey 就会使用代理服务器。proxy 是必需的,是代理服务器的位置和端口。proxyUser 和 proxyPassword 是可选的。用户/密码的值仅在两者存在时才用于凭据。
choco config set proxy <locationandport>
choco config set proxyUser <username>
choco config set proxyPassword <passwordThatGetsEncryptedInFile>
例子
在0.9.9.9中运行以下命令:
choco config set proxy http://localhost:8888
choco config set proxyUser bob
choco config set proxyPassword 123Sup#rSecur3
