* Einem Query-Parameter.
    * Einem Header.
    * Einem Cookie.
* `http`: Standard-HTTP-Authentifizierungssysteme, einschließlich:
    * `bearer`: ein Header `Authorization` mit dem Wert `Bearer` plus einem Token. Dies wird von OAuth2 geerbt.
    * HTTP Basic Authentication.
    * HTTP Digest, usw.
* `oauth2`: Alle OAuth2-Methoden zum Umgang mit Sicherheit (genannt „Flows“).

    * A query parameter.
    * A header.
    * A cookie.
* `http`: standard HTTP authentication systems, including:
    * `bearer`: a header `Authorization` with a value of `Bearer ` plus a token. This is inherited from OAuth2.
    * HTTP Basic authentication.
    * HTTP Digest, etc.
* `oauth2`: all the OAuth2 ways to handle security (called "flows").

    * <a href="https://fastapi.tiangolo.com/features/" class="external-link" target="_blank">**Et bien d'autres fonctionnalités**</a> comme la validation automatique, la sérialisation, l'authentification avec OAuth2 JWT tokens, etc.
* Hashage de **mots de passe sécurisé** par défaut.
* Authentification par **jetons JWT**.
* Modèles **SQLAlchemy** (indépendants des extensions Flask, afin qu'ils puissent être utilisés directement avec des *workers* Celery).

But that will only allow certain types of communication, excluding everything that involves credentials: Cookies, Authorization headers like those used with Bearer Tokens, etc.

So, for everything to work correctly, it's better to specify explicitly the allowed origins.

## Use `CORSMiddleware` { #use-corsmiddleware }

set WRAPPER_LAUNCHER=org.apache.maven.wrapper.MavenWrapperMain

set DOWNLOAD_URL="https://repo.maven.apache.org/maven2/io/takari/maven-wrapper/0.5.6/maven-wrapper-0.5.6.jar"

FOR /F "tokens=1,2 delims==" %%A IN ("%MAVEN_PROJECTBASEDIR%\.mvn\wrapper\maven-wrapper.properties") DO (
    IF "%%A"=="wrapperUrl" SET DOWNLOAD_URL=%%B
)

# Length of API access token.
api.access.token.length=60
# Whether API access token is required.
api.access.token.required=false
# API access token request parameter.
api.access.token.request.parameter=
# Permissions for API admin access.
api.admin.access.permissions=Radmin-api
# Accepted referers for API search.

    @Throws(IOException::class)
    fun parse(responseHeaders: Headers): WebSocketExtensions {
      // Note that this code does case-insensitive comparisons, even though the spec doesn't specify
      // whether extension tokens and parameters are case-insensitive or not.

      var compressionEnabled = false
      var clientMaxWindowBits: Int? = null
      var clientNoContextTakeover = false
      var serverMaxWindowBits: Int? = null

Mas isso só permitirá certos tipos de comunicação, excluindo tudo que envolva credenciais: cookies, cabeçalhos de autorização como aqueles usados ​​com Bearer Tokens, etc.

Então, para que tudo funcione corretamente, é melhor especificar explicitamente as origens permitidas.

## Usar `CORSMiddleware`

Você pode configurá-lo em sua aplicação **FastAPI** usando o `CORSMiddleware`.

	req, err := http.NewRequestWithContext(ctx, http.MethodPost, endpoint, bytes.NewReader(buf))
	if err != nil {
		return err
	}

	if token != "" {
		req.Header.Set("Authorization", token)
	}
	req.Header.Set("Content-Type", "application/json")

	clnt := http.Client{Transport: getRemoteInstanceTransport()}
	resp, err := clnt.Do(req)
	if err != nil {
		return err
	}

	xhttp.DrainBody(resp.Body)
