注意: 由于您的代码在紧密循环中进行持续请求，应仅对 测试 Web 服务/站点运行它。
在 Windows PowerShell 中，您**_必须_使用 try / catch**：
while (
429 -ne
$(try { $null=Invoke-WebRequest @req } catch { $_.Exception.Response.StatusCode })
) { }
在 PowerShell (Core) 7+ 中，您可以使用 -SkipHttpErrorCheck 开关：
while (429 -ne (Invoke-WebRequest -SkipHttpErrorCheck @req).StatusCode) { }

Caveat: Given that your code makes ongoing requests in a tight loop, it should only be run against a test web service / site.
> I don't want to use do or try or catch methods.
In Windows PowerShell, you must use try / catch:
while (
429 -ne
$(try { $null=Invoke-WebRequest @req } catch { $_.Exception.Response.StatusCode })
) { }
In PowerShell (Core) 7+, you can use the -SkipHttpErrorCheck switch:
while (429 -ne (Invoke-WebRequest -SkipHttpErrorCheck @req).StatusCode) { }
