## OpenID Connect

OpenID Connect - это еще один протокол, основанный на **OAuth2**.

Он просто расширяет OAuth2, уточняя некоторые вещи, не имеющие однозначного определения в OAuth2, в попытке сделать его более совместимым.

Например, для входа в Google используется OpenID Connect (который под собой использует OAuth2).

Но вход в Facebook не поддерживает OpenID Connect. У него есть собственная вариация OAuth2.

## استاندارد OpenID Connect

استاندارد OpenID Connect، مشخصه‌ای دیگر است که بر پایه **OAuth2** ساخته شده است.

این مشخصه، به گسترش OAuth2 می‌پردازد و برخی مواردی که در OAuth2 نسبتاً تردید برانگیز هستند را مشخص می‌کند تا سعی شود آن را با سایر سیستم‌ها قابل ارتباط کند.

به عنوان مثال، ورود به سیستم گوگل از OpenID Connect استفاده می‌کند (که در زیر از OAuth2 استفاده می‌کند).

        }
        else -> {
          events += "plan $id TCP connected"
          connectState = ConnectState.TCP_CONNECTED
          ConnectResult(this)
        }
      }
    }

    override fun connectTlsEtc(): ConnectResult {
      check(connectState == ConnectState.TCP_CONNECTED)
      events += "plan $id TLS connecting..."

 2. It attempts to retrieve a connection with that address from the **connection pool**.
 3. If it doesn't find a connection in the pool, it selects a **route** to attempt. This usually means making a DNS request to get the server's IP addresses. It then selects a TLS version and proxy server if necessary.

    val connect1 = server.takeRequest()
    assertThat(connect1.requestLine).isEqualTo("CONNECT android.com:443 HTTP/1.1")
    assertThat(connect1.headers["Proxy-Authorization"]).isNull()
    val connect2 = server.takeRequest()
    assertThat(connect2.requestLine).isEqualTo("CONNECT android.com:443 HTTP/1.1")
    assertThat(connect2.headers["Proxy-Authorization"]).isEqualTo("password")
