我今天已经杀了3个小时而且不明白为什么?
我有简单的脚本:
$user = 'icm'
$pass = 'icm'
$pair = "$($user):$($pass)"
$url = 'http://####:15672/api/queues/%2f/ICM.Payments.Host.1'
$encodedCreds = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($pair))
$basicAuthValue = "Basic $encodedCreds"
$headers = @{
Authorization = $basicAuthValue
}
$request = Invoke-WebRequest -Uri $url -Headers $headers -ContentType "application/json"
$messages = ($request.Content | ConvertFrom-Json | Select -ExpandProperty messages)
$messages
所以,通过PS ISE它可以很好地工作,但是通过powershell.exe我看到下面的错误。
Invoke-WebRequest : {"error":"Object Not Found","reason":"\"Not Found\"\n"}
At C:\Temp\Untitled1.ps1:16 char:12
+ $request = Invoke-WebRequest -Uri $url -Headers $headers -ContentType ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest], WebException

ConvertFrom-Json : Cannot bind argument to parameter 'InputObject' because it is null.

证明attached。
答案 0 :(得分:0)
我对RabbitMQ也有同样的问题,原因是URL中%2f
的转义。
见Percent-encoded slash (“/”) is decoded before the request dispatch
通过上述答案的技巧,它可以在ISE和控制台中运行:
$urlFixSrc = @"
using System;
using System.Reflection;
public static class URLFix
{
public static void ForceCanonicalPathAndQuery(Uri uri)
{
string paq = uri.PathAndQuery;
FieldInfo flagsFieldInfo = typeof(Uri).GetField("m_Flags", BindingFlags.Instance | BindingFlags.NonPublic);
ulong flags = (ulong) flagsFieldInfo.GetValue(uri);
flags &= ~((ulong) 0x30);
flagsFieldInfo.SetValue(uri, flags);
}
}
"@
Add-Type -TypeDefinition $urlFixSrc -Language CSharp
$url = [URI]$url
Invoke-WebRequest -Uri $url -Headers $headers -ContentType "application/json"
