研究方向

Start by tracing the NuGet v2 API handling for FindPackagesById() and the IsLatestVersion filter, comparing the reported request with and without a leading space. Reproduce the response for Microsoft.PowerShell.PSResourceGet and inspect the code and tests that build the feed XML. Done means the API returns one package entry for the filtered package ID, with valid feed structure.

描述

Prerequisites
  • Write a descriptive title.
  • Make sure you are able to repro it on the latest version
  • Search the existing issues.
Steps to reproduce
  • Call FindPackagesById() for package JiraPS via the PSGallery NuGet v2 API - example API call: https://www.powershellgallery.com/api/v2/FindPackagesById()?id=%27JiraPS%27&$filter=IsLatestVersion
  • Repeat the same API call for package Microsoft.PowerShell.PSResourceGet - example call: https://www.powershellgallery.com/api/v2/FindPackagesById()?id=%27Microsoft.PowerShell.PSResourceGet%27&$filter=IsLatestVersion
  • Repeat the same API call for package Microsoft.PowerShell.PSResourceGet, but this time add a space to the front of the filter string: https://www.powershellgallery.com/api/v2/FindPackagesById()?id=%27Microsoft.PowerShell.PSResourceGet%27&$filter=%20IsLatestVersion
Expected behavior
All 3 API calls return one and only one package (with the latest version) for their respective package IDs
Actual behavior
API call #2 returns invalid NuGet XML response, but calls 1 and 3 work as expected

XML response from API call number 2 is:

Of particular interest is:

  • <m:count>1</m:count> suggests one <entry> should be present, but there are none.
  • <author> should be under an <entry>, not the <feed>. (It's also null for some reason?)
