在 PowerShell 中进行 Http post 调用时,将 JSON 正文中的字段设置为文件中的内容

setting the field in the JSON body to contents in a file while making a Http post call in PowerShell

我正在尝试安装由 digicert CA 颁发的证书。首先,我使用 Powershell 脚本生成 CSR(证书签名请求)。我将生成的 CSR 放在一个 txt 文件中,并删除所有换行符、空格和回车 returns。我正在使用以下脚本来执行此操作:

$CSR > C:\Scripts\CSR.txt
$path = "C:\Scripts\CSR.txt"
(Get-Content $path -Raw).Replace("`r`n","") | Set-Content $path -Force
(Get-Content $path -Raw).Replace(" ","") | Set-Content $path -Force
(Get-Content $path -Raw).Replace("`r`n","") | Set-Content $path -Force -NoNewline

之后,我想对 digiCert 进行 http post 调用以获取证书 ID。为此,我正在使用以下脚本:

[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"
$body = @"
{
 "profile_name": "XXX",
 "common_name": "XX",
 "additional_dns_names": [
   "XX",
   "XX"
 ],
 "csr":$CSRWithNoCRLF,

 "signature_hash": "sha256",
 "validity": {
   "months": 36
 },
 "organization": {
   "name": "XXX",
   "units": [

   ]
 }
}
"@


$header = @{
 "Accept"="application/json"
 "KEY"="XXXX"
 "Content-Type"="application/json"
} 

$response = Invoke-WebRequest -Uri "https://www.digicert.comXXXX" -Method Post -Body $body -Headers $header 
$Content = $response.Content

对于JSON正文中的csr字段,我想直接复制C:\Scripts\CSR.txt文件的内容。我尝试了以下方法,但它不起作用。

$CSRWithNoCRLF = Get-Content $path

并使用 $CSRWithNoCRLF 作为 csr 的值。但是 Get-Content 正在添加换行符和回车 returns 并使 CSR 值变形。所以这是行不通的。关于如何解决这个问题的任何想法?

Get-Content is adding line breaks

多种方式,每一种都是完整的解决方案:

$CSRWithNoCRLF = Get-Content $path -Raw     # requires PSv3+

Get-Content $path | Out-String

(Get-Content $path) -join "`n"       # use "`r`n" for Windows-style line-endings

Edit

检查您发送的内容。试试这个:

[regex]::Escape($Body)

如果您使用 (Get-Content $path) -join "n"`,那么 CSR 部分将不会有 \r\n 行结尾。但是,您为什么要手工制作 JSON?如果您这样做windows 框,您的 JSON 字符串中会有 Windows 行结尾。

试试这个:

$Body = [pscustomobject]@{
    profile_name = "XXX"
    common_name = "XX"
    additional_dns_names = @(
        "XX",
        "XX"
    )
    csr = (Get-Content $Path) -join "`n"
    signature_hash = "sha256"
    validity = [pscustomobject]@{
        months = 36
    }
    organization = [pscustomobject]@{
        name = "XXX"
        units = @()
    }

} | ConvertTo-Json -Compress

请注意,我使用的是 Compress

> [regex]::Escape($Body) -match '\r'
False

试一试。

试试这个:

$CSRWithNoCRLF = (Get-Content $path -Raw).Replace("`r`n","").Replace(" ","")
$body = @"
{
 "profile_name": "XXX",
 "common_name": "XX",
 "additional_dns_names": [
   "XX",
   "XX"
 ],
 "csr":"$CSRWithNoCRLF",

 "signature_hash": "sha256",
 "validity": {
   "months": 36
 },
 "organization": {
   "name": "XXX",
   "units": [

   ]
 }
}
"@
$header = @{
 "Accept"="application/json"
 "KEY"="XXXX"
 "Content-Type"="application/json"
} 

$response = Invoke-WebRequest -Uri "https://www.digicert.comXXXX" -Method Post -Body $body -Headers $header 
$Content = $response.Content

我看修改后不需要将证书存回文件。
