如何输出原始 JSON？还是格式化？

Answer 1

您可以获得如下原始响应

(Invoke-WebRequest http://ipinfo.io/json ).rawcontent

或者解析 JSON 然后 select 您感兴趣的属性：

Invoke-WebRequest http://ipinfo.io/json | ConvertFrom-Json

Answer 2

您可以使用 WebClient 将 JSON 下载为字符串：

$wc = New-Object System.Net.WebClient
$json = $wc.DownloadString("http://ipinfo.io/json")

要使用 WebResponse，您需要 ex。 a StreamReader 阅读回复。例如：

$request = [System.Net.WebRequest]::Create("http://ipinfo.io/json")
#GET is default
#$request.Method = "GET"
$response = $request.GetResponse()
$reader = New-Object -TypeName System.IO.StreamReader -ArgumentList $response.GetResponseStream(), $response.CharacterSet

#Get JSON response
$JSON = $reader.ReadToEnd()

#Cleanup
$reader.Close()
$response.Close()
