Graph API 使用 Powershell 发送电子邮件，并在 html 正文中使用 & 符号

我试图发送图形API电子邮件与html正文有一个href URL，其中有&符号。

尝试编码&如%26和电子邮件收到的%26在它，当点击它抛出404错误。

尝试将内容类型更改为"application/x-www-form-urlencoded"但这样就不会触发电子邮件了。

示例代码:

我有$toJsonAddress作为数组。

$htmlhead="<html>
<style>
body {
font-family: 'verdana';font-size: 16px;
}
h1 {
font-family: 'verdana';font-size: 18px;color: grey;
}
h2 {
font-family: 'verdana';font-size: 18px;color: #2596be;
}
h3 {
font-family: 'verdana';font-size: 16px;color: black;
}
</style>"
#Header for the message
$HtmlBody = "<body>
<h1>test</h1>
<p>request <a href=""https://www.somedomain/help?id=sc_cat_item&amp;sys_id=12345"">here.</a></p>
"
$content = "</body></html>" + $HtmlHead + $HtmlBody | ConvertTo-Json
Write-Output "content is -->> $content"
$URLsend = "https://graph.microsoft.com/v1.0/users/$MailSender/sendMail"
$BodyJsonsend = @"
{
"message": {
"subject": "$mailSubject",
"body": {
"contentType": "HTML",
"content": "$content "
},
"toRecipients": [
$toJsonAddress
]
},
"saveToSentItems": "false"
}
"@
Invoke-RestMethod -Method POST -Uri $URLsend -Headers $headers -Body $BodyJsonsend -ContentType "application/x-www-form-urlencoded"

JSON被转换打印，收到如下错误:

content is -->> "</body></html><html>rn<style>rntbody {rnttfont-family: 'verdana';font-size: 16px;rnt}rnth1 {rnttfont-family: 'verdana';font-size: 18px;color: grey;rnt}rnth2 {rnttfont-family: 'verdana';font-size: 18px;color: #2596be;rnt}rnth3 {rnttfont-family: 'verdana';font-size: 16px;color: black;rnt}rn</style><body>rn     <h1>test</h1>rn<p>request <a href="https://www.somedomain/help?id=sc_cat_item&amp;sys_id=12345">here.</a></p>rn"

尝试使用字符&代替&。

另外href属性中的URL应该用双引号括起来

$HTMLBody = "<html><body><p>Portal: <a href=""https://sampledns/overview?ff=abc&amp;ln=xyz"">some text</a></p></body></html>"
