Json 调用RestMethod Powershell V3内容类型

我能够使用powershell v5中的JIRA rest API。但是，相同的代码在powershell v3中抛出以下错误

WARNING: Remote Server Response: The 'Content-Type' header must be modified using the appropriate property or method.

源代码

$basicAuth = "Basic " + [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes("$($Username):$Password"))
    $headers = @{
        "Authorization" = $basicAuth
        "Content-Type"="application/json"
    }

 $response = Invoke-RestMethod -Uri $requestUri -Method POST -Headers $headers -Body $body

---

Invoke Restmethod有一个-ContentType参数，因此错误似乎表明您应该使用它来指定内容类型，而不是通过headers参数传递它：

$basicAuth = "Basic " + [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes("$($Username):$Password"))
    $headers = @{
        "Authorization" = $basicAuth
    }

 $response = Invoke-RestMethod -Uri $requestUri -Method POST -Headers $headers -Body $body -ContentType 'application/json'
