使用Powershell对http请求进行JSON对象格式化

我正在从事一个与Slack集成的项目，当我试图向API发送数据时遇到了一些问题，因为它需要格式化的块需要一个Json对象

使用Slack Block Builder，我知道它期望：

    "blocks": [        
        {
            "type": "section",
            "text": {
                "type": "mrkdwn",
                "text": "http://bar.com"
            }
        }
    ]

这就是我试图为

chat.postMessage

方法构造对象和参数以发送到API的方式

$messageText = 'http://bar.com'
$blocksDetailObj = [PSCustomObject]@{'type' = '"mrkdwn"'
                     'text' = $messageText}


$blocksObject = [PSCustomObject]@{ 'type' = '"section"'
                   'text' = $blocksDetailObj }

$blocksArray = @()

$blocksArray += $blocksObject

$queryStringParameters = @{ 'token' = $botToken 
                            'channel' = $channelID
                            'text' = 'fallback text'
                            'blocks' = $blocksArray 
                                     }

任何帮助或文档都将不胜感激。

您可能希望签出一个PS模块，以与Slack API交互，或者按照建议。你可以找到一篇很长的博客文章，上面给出了如何使用它的上下文

如果您不想直接使用这些模块，请查看：
