检查 URL 状态的脚本 [英] Script to check the status of a URL
问题描述
我看到过一些与此类似的问题，但没有找到适合我的情况的问题.
I have seen a few questions similar to this but have not found one that will work for my situation.
我有一个存储在文本文件中的 URL 列表，我需要运行该列表以查看它们是否返回 404 错误.我正在使用 powershell 并且一直在使用这里的示例:http://gallery.technet.microsoft.com/scriptcenter/Powershell-Script-for-13a551b3#content
I have a list of URL's stored in a text file that I need to run through to see if they return a 404 error. I am using powershell and have been using the example here: http://gallery.technet.microsoft.com/scriptcenter/Powershell-Script-for-13a551b3#content
我目前正在测试一个 Confluence 页面的链接，在 Chrome 中查看控制台我可以看到返回的第一个状态是 404 - Not Found，然后是 304、200 之后的十几个请求.
I am currently testing a link to a confluence page, watching the console in Chrome I can see the first status returned is a 404 - Not Found, then a dozen or so requests afterwards that are 304, 200.
我猜测第一个 404 之后的请求会影响我的结果，我需要脚本根据第一个响应返回.
I am guessing the requests after the first 404 are affecting my results, I need the script to return based on that first response.
到目前为止，我已经尝试过 powershell、php 和 javascript 解决方案，但都没有成功.
I have tried powershell, php and javascript solutions with no luck so far.
总而言之，有没有一种方法可以仅根据第一个响应返回答案?
So all in all is there a way to return an answer based on the first response alone?
脚本:
## The URI list to test
$URLListFile = "H:\xxx\xxx\urlList.txt"
$URLList = Get-Content $URLListFile -ErrorAction SilentlyContinue
$Result = @()
Foreach($Uri in $URLList) {
$time = try{
$request = $null
## Request the URI, and measure how long the response took.
$result1 = Measure-Command { $request = Invoke-WebRequest -Uri $uri }
$result1.TotalMilliseconds
}
catch
{
<# If the request generated an exception (i.e.: 500 server
error or 404 not found), we can pull the status code from the
Exception.Response property #>
$request = $_.Exception.Response
$time = -1
}
$result += [PSCustomObject] @{
Time = Get-Date;
Uri = $uri;
StatusCode = [int] $request.StatusCode;
StatusDescription = $request.StatusDescription;
ResponseLength = $request.RawContentLength;
TimeTaken = $time;
}
}
#Prepare email body in HTML format
if($result -ne $null)
{
$Outputreport = "<HTML><TITLE>Website Availability Report</TITLE><BODY background-color:peachpuff><font color =""#99000"" face=""Microsoft Tai le""><H2> Website Availability Report </H2></font><Table border=1 cellpadding=0 cellspacing=0><TR bgcolor=gray align=center><TD><B>URL</B></TD><TD><B>StatusCode</B></TD><TD><B>StatusDescription</B></TD><TD><B>ResponseLength</B></TD><TD><B>TimeTaken</B></TD</TR>"
Foreach($Entry in $Result)
{
if($Entry.StatusCode -ne "200")
{
$Outputreport += "<TR bgcolor=red>"
}
else
{
$Outputreport += "<TR>"
}
$Outputreport += "<TD>$($Entry.uri)</TD><TD align=center>$($Entry.StatusCode)</TD><TD align=center>$($Entry.StatusDescription)</TD><TD align=center>$($Entry.ResponseLength)</TD><TD align=center>$($Entry.timetaken)</TD></TR>"
}
$Outputreport += "</Table></BODY></HTML>"
}
$Outputreport | out-file H:\xxx\xxx\test.htm
Invoke-Expression H:\xxx\xxx\test.htm
推荐答案
如果你想让你的脚本在第一个错误后退出循环，你可以尝试这样的事情:
If you want your script to exit from the loop after the first error, you could try something like this:
Foreach($Uri in $URLList) {
$error.Clear()
$time = Measure-Command { $request = Invoke-WebRequest -Uri $uri } 2>$null
if ($error.Count -eq 0) {
$time.TotalMilliseconds
} else {
$error[0].Exception.Response
break
}
}
此处不需要 AFAICS try..catch.
AFAICS try..catch isn't needed here.
