# Query Parameters and String Validations { #query-parameters-and-string-validations }

**FastAPI** allows you to declare additional information and validation for your parameters.

Let's take this application as example:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

    val address = factory.newAddress()
    assertThat(address.toString())
      .isEqualTo("Address{example.com:80, proxySelector=RecordingProxySelector}")
  }

  @Test fun addressWithProxyToString() {
    val address = factory.newAddress(proxy = Proxy.NO_PROXY)
    assertThat(address.toString())
      .isEqualTo("Address{example.com:80, proxy=${Proxy.NO_PROXY}}")
  }

- Choice of erasure set size is automatic based on the number of drives available, let's say for example if there are 32 servers and 32 drives which is a total of 1024 drives. In this scenario 16 becomes the erasure set size. This is decided based on the greatest common divisor (GCD) of acceptable erasure set sizes ranging from *4 to 16*.

* `allow_origins` - Cross-origin request yapmasına izin verilmesi gereken origin’lerin listesi. Örn. `['https://example.org', 'https://www.example.org']`. Herhangi bir origin’e izin vermek için `['*']` kullanabilirsiniz.
* `allow_origin_regex` - Cross-origin request yapmasına izin verilmesi gereken origin’lerle eşleşecek bir regex string’i. Örn. `'https://.*\.example\.org'`.

For that, you can use the `WSGIMiddleware` and use it to wrap your WSGI application, for example, Flask, Django, etc.

## Using `WSGIMiddleware` { #using-wsgimiddleware }

/// info

This requires installing `a2wsgi` for example with `pip install a2wsgi`.

///

You need to import `WSGIMiddleware` from `a2wsgi`.

Then wrap the WSGI (e.g. Flask) app with the middleware.
