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。

Windows PowerShell 中,您**_必须_使用 try / catch**:

while (
 429 -ne 
 $(try { $null=Invoke-WebRequest @req } catch { $_.Exception.Response.StatusCode })
) { }

PowerShell (Core) 7+ 中,您可以使用 -SkipHttpErrorCheck 开关:

while (429 -ne (Invoke-WebRequest -SkipHttpErrorCheck @req).StatusCode) { }

有关详细信息,请参阅此答案

英文:

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) { }
