# Settings and Environment Variables { #settings-and-environment-variables }

In many cases your application could need some external settings or configurations, for example secret keys, database credentials, credentials for email services, etc.

Most of these settings are variable (can change), like database URLs. And many could be sensitive, like secrets.

For this reason it's common to provide them in environment variables that are read by the application.

// Get returns the sets representation of the endpoints
// this function also intelligently decides on what will
// be the right set size etc.

 *  Breaking: Replace `SocketPolicy` with a new type, `SocketEffect`. It splits triggers (request
    start, response body, etc.) from effects (closing the socket, closing the stream, etc.).

 *  Breaking: Rename `RecordedRequest.sequenceNumber` to `exchangeIndex` and introduce
    `connectionIndex` on that type. These properties may be useful when testing features like

     * Equivalence<@Nullable Number>. That can still produce wrappers of various types --
     * Wrapper<Number>, Wrapper<Integer>, Wrapper<@Nullable Integer>, etc. If we used just
     * Equivalence<? super T> below, no type could satisfy both that bound and T's own
     * bound. With this type, they have some overlap: in our example, Equivalence<Number>
     * and Equivalence<Object>.

### Tóm lại

Bạn khai báo **một lần** kiểu dữ liệu của các tham số, body, etc là các tham số của hàm số.

Bạn định nghĩa bằng cách sử dụng các kiểu dữ liệu chuẩn của Python.

Bạn không phải học một cú pháp mới, các phương thức và class của một thư viện cụ thể nào.
