* `allow_origin_regex` - Una cadena regex para coincidir con orígenes que deberían estar permitidos para hacer requests cross-origin. por ejemplo, `'https://.*\.example\.org'`.

For example, in the URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...the query parameters are:

* `skip`: with a value of `0`
* `limit`: with a value of `10`

As they are part of the URL, they are "naturally" strings.

But when you declare them with Python types (in the example above, as `int`), they are converted to that type and validated against it.

## Read env vars in Python { #read-env-vars-in-python }

You could also create environment variables **outside** of Python, in the terminal (or with any other method), and then **read them in Python**.

For example you could have a file `main.py` with:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

```JSON hl_lines="4-8"
{
    "openapi": "3.1.0",
    // More stuff here
    "servers": [
        {
            "url": "/api/v1"
        }
    ],
    "paths": {
            // More stuff here
    }
}
```

    /**
     * Creates an {@link java.io.OutputStream} for writing to a file
     * on an SMB server addressed by the URL parameter. See {@link
     * jcifs.smb1.smb1.SmbFile} for a detailed description and examples of
     * the smb URL syntax.
     *
     * @param url An smb URL string representing the file to write to
     * @throws SmbException if an SMB error occurs

```

### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

# Allow the root user to perform any action.
allow {
 input.owner == true
}

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install python-multipart
```

This is supported since FastAPI version `0.113.0`. 🤓
