Invoke-WebRequest 一个返回 json 字符串的 API 返回整数列表？

Question

在 Chrome DevTools 的网络选项卡中，我右键单击请求并选择“Copy => Copy as PowerShell”并获得以下脚本。请求的“响应”是一个 json 字符串。

$session = New-Object Microsoft.PowerShell.Commands.WebRequestSession
 $session.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.81 Safari/537.36"
 $session.Cookies.Add((New-Object System.Net.Cookie("INGRESSCOOKIE", "1661198715.885.38.892935", "/", "xx.com")))
 $response = Invoke-WebRequest -UseBasicParsing -Uri "https://xx.com/api/v1/xxx?filter[reportDate]=2022-08-24&filter[forceReload]=true" `
 -WebSession $session `
 -Headers @{
 "method"="GET"
   "authority"="xx.com"
   "scheme"="https"
   "path"="/api/v1/sum? Filter[reportDate]=2022-08-24&filter[forceReload]=true"
   "sec-ch-ua"="`"Chromium`";v=`"94`", `"Google Chrome`";v=`"94`", `";Not A Brand`";v=`"99`""
   "accept"="application/vnd.api+json"
   "authorization"="Bearer $($token. Token)"
   "sec-ch-ua-mobile"="?0"
   "sec-ch-ua-platform"="`"Windows`""
   "origin"="https://xx.com"
   "sec-fetch-site"="same-site"
   "sec-fetch-mode"="cors"
   "sec-fetch-dest"="empty"
   "referrer"="https://xx.com/"
   "accept-encoding"="gzip, deflate, br"
   "accept-language"="en-US,en;q=0.9"
 } `
 -ContentType "application/vnd.api+json"

但是，Write-Output $response.Content得到的是整数列表而不是 json 字符串？

这$response.RawContent是

如何解码响应内容？

Answer 1

更改"accept-encoding"="gzip, deflate, br"为"accept-encoding"="gzip, deflate"(no br) 解决了问题。
