在 PowerShell 中处理 JSON 中的 html 字符串

Question

我有一个包含 HTML 字符串的 JSON 文件，并一直在使用 PowerShell 对其进行操作，但是每次我将其转换回 JSON 时，都会使 HTML 字符串不再相同。

确实需要一些帮助。谢谢！ 这是我的 JSON：

{
"count": 1,
"value": [
    {
        "id": 1,
        "fields": {
            
                       "System.Description": "<div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\"><div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\"><span style=\"font-family:Arial, sans-serif;background-color:rgb(255, 255, 255);display:inline !important;\">Decision has been made to use HLS video format</span><br></span></div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\"><span style=\"font-family:Arial, sans-serif;background-color:rgb(255, 255, 255);display:inline !important;\"><br></span></span></div><p style=\"margin:0cm 0cm 8pt;font-size:11pt;font-family:Calibri, sans-serif;margin-bottom:0cm;margin-bottom:.0001pt;text-autospace:none;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\">We\ncan’t use YouTube or Vimeo to serve the videos because analytics required.</span></p></div>We\nneed to use an HTML5 Player in the Desktop web app</span></div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\"><br></span></div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><br></div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><br></div></div><br>",

我假设问题是从自定义对象返回 json 时的编码字符。这是一个解决方法：

$json = @'
{
"count": 1,
"value": [
    {
        "id": 1,
        "fields": {
            
                       "System.Description": "<div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\"><div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\"><span style=\"font-family:Arial, sans-serif;background-color:rgb(255, 255, 255);display:inline !important;\">Decision has been made to use HLS video format</span><br></span></div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\"><span style=\"font-family:Arial, sans-serif;background-color:rgb(255, 255, 255);display:inline !important;\"><br></span></span></div><p style=\"margin:0cm 0cm 8pt;font-size:11pt;font-family:Calibri, sans-serif;margin-bottom:0cm;margin-bottom:.0001pt;text-autospace:none;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\">We\ncan’t use YouTube or Vimeo to serve the videos because analytics required.</span></p></div>We\nneed to use an HTML5 Player in the Desktop web app</span></div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><span style=\"font-size:10.0pt;font-family:&quot;Arial&quot;,sans-serif;\"><br></span></div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><br></div><div style=\"margin:0px 0cm 0.000133333px;font-size:11pt;font-family:Calibri, sans-serif;\"><br></div></div><br>"

        }

'@
$obj = $json | ConvertFrom-Json
# Manipulate $obj in here
[regex]::Replace(($obj | ConvertTo-Json -depth 10),'\\u[0-9a-f]{4}',{param ($m) [regex]::Unescape($m)})

您可以使用 Regex 类方法Unescape() 转换 unicode 字符代码。
