Send-SendGridEmail @splat

例如，在蔚蓝的Powershell Runbook上，将html正文减少到仅一行时，就发生这种情况

<table>
<tr>
<td align="left">
<p>Hello,</p>
<p>Test message</p> 
</td>
</tr>
</table>
"@

确实有效。

Answer 1

Send-SendGridEmail：Invoke-RestMethod出错，远程服务器返回错误：（415）不支持的媒体类型。

这会使Authorization标头之后的所有标头被视为消息正文，并被有效地忽略。通过简单的trim传递即可解决此问题：

$apiKey = trim($apiKey);
