Inconsistencies in the way az rest parses ' and " between regular and interactive CLI

[DavyJonesStockings]

Describe the bug

Hi all,

While investigating the following issue that I encountered with az consumption budget create: #29950
I came across a strange inconsistency in the way commands are parsed in the interactive CLI and the regular CLI. One commentor suggested a fix of using az rest and adjusting the body, and this kind of ended up fixing the issue.

Related command

The following command works in the interactive CLI but not the regular CLI. In the regular CLI, it throws an error (the az prefix is excluded in interactive mode).

az rest --method PUT --url 'https://management.azure.com/subscriptions/2a62e50d-4f3d-432d-8627-5acbe1680c8c/providers/Microsoft.Consumption/budgets/monthlyBudget?api-version=2023-05-01' --body '{"properties":{"amount":10.0,"category":"cost","filter":{},"timeGrain":"monthly","timePeriod":{"endDate":"2027-01-01T05:00:00.000Z","startDate":"2026-06-01T04:00:00.000Z"}}}'

The error attached can be remedied if the user replaces all single quotes with double quotes and instead uses \" to escape double quotes within the command.

Errors

The command failed with an unexpected error. Here is the traceback:
No connection adapters were found for "'https://management.azure.com/subscriptions/2a62e50d-4f3d-432d-8627-5acbe1680c8c/providers/Microsoft.Consumption/budgets/monthlyBudget?api-version=2023-05-01'"

Based on the traceback, the error seems to stem from the fact that the --url parameter is not parsed properly in the regular CLI, thus leading to a URL submitted between single quotes to remain underneath single quotes.

Your CLI is up-to-date.

Additional context

There seems to be a number of similar bugs that stem from strange parsing between single and double quotes; in the regular CLI, another one I found during this process involved wrapping only the --url in double quotes but leaving the --body in single quotes (with double quotes inside for the json). This led to the api request body in debug mode appearing as being entirely wrapped in double quotes (as in, double quotes AROUND the json object) and also having stripped all of the double quotes from inside of the json (which somehow led to an authorization error...?). I'm unsure if these are all related to one single parsing issue, but one step at a time :)

Thank you for opening this issue, we will look into it.

[DavyJonesStockings]

After looking a bit closer, there's important details here. I was running commands from cmd.exe, treating it like a Unix shell. This is a form of user error because single quotes are treated differently by the command prompt; the command prompt shell is why they're being passed into the argument itself as a literal character. However, this is still an inconsistency that might be worth looking at for the sake of convenience; many of the docs use examples with single quotes, as well as the discrepancy between it working in the interactive CLI but not the regular CLI (ie you could run a command in the interactive CLI, put it in a .sh script, and have it fail when run).

[azclibot]

Thanks for the detailed report and the follow-up clarification!

Issue Summary:
On Windows cmd.exe, single quotes are treated as literal characters (unlike bash/zsh), so a command like:

az rest --method PUT --url 'https://...' --body '{...}'

passes the URL as 'https://...' (with literal single quotes) to the CLI. This causes az rest to fail with No connection adapters were found for "'https://...".

However, the interactive CLI (az interactive) strips the surrounding single quotes before parsing, making the same command work there — creating an inconsistency.

Root cause area: azure/cli/core/util.py → send_raw_request (or argument pre-processing in interactive mode via azext_interactive).

Suggested investigation:

1. Check how az interactive pre-processes arguments before dispatching — it likely strips surrounding single quotes from values.
2. Evaluate whether az rest (and possibly all commands) should normalize arguments that have mismatched/unnecessary surrounding single quotes on Windows, or at least emit a clear warning.
3. Consider adding a user-friendly error message when the URL contains leading/trailing quotes (e.g., "It looks like your URL contains surrounding quotes — if you're using cmd.exe, replace single quotes with double quotes").

Repro environment: Windows 11, cmd.exe, Azure CLI 2.87.0 (MSI), az rest command.

Thanks for the detailed report! This issue involves an inconsistency in how az rest handles single-quoted arguments between regular CLI (e.g., cmd.exe on Windows) and the interactive CLI (az interactive).

Root cause summary:

• On Windows cmd.exe, single quotes are not shell metacharacters and are passed through literally to the CLI process. So --url 'https://...' passes the URL string with the surrounding single quotes included.
• The az interactive mode appears to strip single quotes during its own argument parsing, so the same command works there.

What to fix:
The send_raw_request function in azure/cli/core/util.py (or the az rest argument parsing in azure/cli/command_modules/util/custom.py) should strip surrounding single quotes from --url and --body arguments on Windows, OR the interactive CLI's extra quote-stripping should be reconciled with the regular CLI to produce consistent behavior.

Key files to investigate:

• src/azure-cli-core/azure/cli/core/util.py — send_raw_request function
• src/azure-cli/azure/cli/command_modules/util/custom.py — rest_call / argument handling

The fix should handle both --url and --body parameters consistently across platforms.
