Powershell-JSON格式到PAC文件的转换

Question

我使用了以下代码来显示JSON结果，但现在需要更改脚本以显示输出，而不是并排显示。我试过下面这样的脚本，但似乎无法实现我想要的。

我的问题是：

• 我想删除最后一个括号之前的||。if (shExpMatch(host, "*.lync.com") || shExpMatch(host, "*.teams.microsoft.com") || shExpMatch(host, "teams.microsoft.com") || )因此，它将是if (shExpMatch(host, "*.lync.com") || shExpMatch(host, "*.teams.microsoft.com") || shExpMatch(host, "teams.microsoft.com"))

• 我需要更改脚本以显示我想要的输出，而不是并排显示。

这是我的脚本：

$result = Invoke-WebRequest "https://endpoints.office.com/endpoints/worldwide?noipv6&ClientRequestId=b10c5ed1-bad1-445f-b386-b919946339a7"
$services = ConvertFrom-Json $result
$likeFilter = "12"
$services = $services | Where-Object { $_.id -like $likeFilter } 
$urls = [System.Collections.ArrayList]@()

$services




function add_url($url){
if(!$urls.Contains($url)){ $urls.Add($url); }
}



foreach($service in $services){

foreach($url in $service.urls){ add_url($url);
}
}

# OUTPUT
$txt_proxypacText += "// This PAC file will provide proxy config to Microsoft 365 services`r`n"
$txt_proxypacText += "//  using data from the public web service for all endpoints`r`n"
$txt_proxypacText += "function FindProxyForURL(url, host)`r`n"
$txt_proxypacText += "{`r`n"
$txt_proxypacText += "var direct = ""DIRECT"";`r`n"
$txt_proxypacText += "var proxyServer = ""PROXY 10.11.12.13:8080"";`r`n"
$txt_proxypacText += "host = host.toLowerCase();`r`n"
$txt_proxypacText += "if ("
foreach($url in $urls){
$txt_proxypacText += "shExpMatch(host, ""$url"") || "
}

$txt_proxypacText += ")`r`n"
$txt_proxypacText += "{`r`n"
$txt_proxypacText += "`r`n return direct;"
$txt_proxypacText += "`r`n}"
$txt_proxypacText += "`r`n return proxyServer;"
$txt_proxypacText += "`r`n}"

输出：

// This PAC file will provide proxy config to Microsoft 365 services
//  using data from the public web service for all endpoints
function FindProxyForURL(url, host)
{
var direct = "DIRECT";
var proxyServer = "PROXY 10.11.12.13:8080";
host = host.toLowerCase();
if (shExpMatch(host, "*.lync.com") || shExpMatch(host, "*.teams.microsoft.com") || shExpMatch(host, "teams.microsoft.com") || )
{
return direct;
}
return proxyServer;
}

我想要的输出：

// This PAC file will provide proxy config to Microsoft 365 services
//  using data from the public web service for all endpoints
function FindProxyForURL(url, host)
{
var direct = "DIRECT";
var proxyServer = "PROXY 10.11.12.13:8080";
host = host.toLowerCase();
if(shExpMatch(host, "*.lync.com")
|| shExpMatch(host, "*.teams.microsoft.com")
|| shExpMatch(host, "teams.microsoft.com"))
{
return direct;
}
return proxyServer;
}

Answer 1

我会使用带有一组预先格式化的shExpMatch(..)行的Here字符串。使用它还可以避免使用+=进行双引号和字符串串联

# demo urls
$urls = "*.lync.com", "*.teams.microsoft.com", "teams.microsoft.com"

$hostMatches = $(for ($i = 0; $i -lt $urls.Count; $i++) {
$prefix = if ($i -eq 0) { '' } else { '        || '}
'{0}shExpMatch(host, "{1}")'-f $prefix,  $urls[$i]
}) -join [Environment]::NewLine

$txt_proxypacText = @"
// This PAC file will provide proxy config to Microsoft 365 services
//  using data from the public web service for all endpoints
function FindProxyForURL(url, host)
{
var direct = "DIRECT";
var proxyServer = "PROXY 10.11.12.13:8080";
host = host.toLowerCase();
if ($hostMatches)
{
return direct;
}
return proxyServer;
}
"@
$txt_proxypacText

输出：

//此PAC文件将为Microsoft 365服务提供代理配置//为所有端点使用公共web服务中的数据函数FindProxyForURL(url，主机({var direct="direct"；var proxyServer="代理10.11.12.13:8080"；host=host.toLowerCase((；if(shExpMatch(主机，"*.lync.com"(||shExpMatch(主机，"*.teams.microsoft.com/"(||shExpMatch(主机，"teams.microsoft.com/"({直接退货；}return proxyServer；}

根据要求，我认为在代码的顶部，在数组列表中收集URL可以更容易地完成。

请注意：您使用的是一个带有字符串"12"的$likeFilter变量
在这种情况下，您可能会更好地使用-eq运算符，而不是更适合使用通配符进行筛选的-like运算符(即"12*"(。

目前，我假设您只想获得id与"12"完全匹配的服务。

$url    = "https://endpoints.office.com/endpoints/worldwide?noipv6&ClientRequestId=b10c5ed1-bad1-445f-b386-b919946339a7"
$filter = 12
# get an array of urls from the service(s) that get through the filter
$urls = ((Invoke-WebRequest $url | ConvertFrom-Json) | Where-Object { $_.id -eq $filter }).urls | Select-Object -Unique

Answer 2

# EXAMPLE prepare begin
$urls = @(
'microsoft.com',
'*.microsoft.com',
'teams.microsoft.com',
'*.teams.microsoft.com')
# EXAMPLE prepare End
$urlLines = $urls | 
ForEach-Object { return $_.Trim() } |
ForEach-Object { 
if($_.StartsWith('*.')) {
return "shExpMatch(host, '$($_)')"
} else { 
return "host == '$($_)'" 
}}

$innerIf = [String]::Join("`r`n" + (' ' * 8) + "|| ", $urlLines)
#// $txt_proxypacText += "    if ($($innerIf))"
Write-Host "    if ($($innerIf))"
# Output:
# if (host == "microsoft.com"
#    || shExpMatch(host, "*.microsoft.com")
#    || host == "teams.microsoft.com"
#    || shExpMatch(host, "*.teams.microsoft.com"))

Answer 3

我得到了这个-简单的计数器方法：

$counter = 0
foreach($url in $urls){
If ($counter -eq $urls.Count){
$txt_proxypacText += "shExpMatch(host, ""$url"") `r`n"
}else{
$txt_proxypacText += "shExpMatch(host, ""$url"") || `r`n"
}
$counter++
}

可能需要对标签字符进行一些整理。
