changing `.java` files.

 * **Kotlin source compatibility** is the ability to upgrade Kotlin uses of OkHttp 3.x to 4.x
   without changing `.kt` files.

With a few small exceptions (below), OkHttp 4.x is both binary- and Java source-compatible with
OkHttp 3.x. You can use an OkHttp 4.x .jar file with applications or libraries built for OkHttp 3.x.

    * Numaralar (`int`, `float`) maksimum ve minimum gibi sınırlandırmalar yaparken.

* Bunlar gibi en egzotik typelarla bile doğrulama yapabiliyorsunuz.:
    * URL.
    * Email.
    * UUID.
    * ...ve diğerleri.

Bütün doğrulama olayları çok güçlü bir kütüphane sayesinde yapılıyor, **Pydantic**.

### Güvenlik ve kimlik doğrulama

!!! note
    Notice that most of the code is the standard `SQLAlchemy` code you would use with any framework.

    The **FastAPI** specific code is as small as always.

## ORMs

**FastAPI** works with any database and any style of library to talk to the database.

A common pattern is to use an "ORM": an "object-relational mapping" library.

    <example>${fe:formatCode("L", "prettyprint", doc.mimetype, doc.content_description)}</example>
  </function>

  <function>
    <description>Mask e-mail address.</description>
    <name>maskEmail</name>
    <function-class>org.codelibs.fess.taglib.FessFunctions</function-class>
    <function-signature>java.lang.String maskEmail(java.lang.String)</function-signature>

    // Wrong public key.
    assertThat(okHttpCertificate.checkSignature(certificate.keyPair.public)).isFalse()
  }

  /**
   * We don't have API support for rfc822Name values (email addresses) in the subject alternative
   * name, but we don't crash either.
   */
  @Test
  fun `unsupported general name tag`() {
    val certificateByteString =
      (

pkg net/http, type Transport struct, ProxyConnectHeader Header
pkg net/http, var ErrAbortHandler error
pkg net/http, var ErrServerClosed error
pkg net/http, var NoBody noBody
pkg net/mail, func ParseDate(string) (time.Time, error)
pkg net, method (*Buffers) Read([]uint8) (int, error)
pkg net, method (*Buffers) WriteTo(io.Writer) (int64, error)

### Synchronous Get ([.kt][SynchronousGetKotlin], [.java][SynchronousGetJava])

Download a file, print its headers, and print its response body as a string.

The `string()` method on response body is convenient and efficient for small documents. But if the response body is large (greater than 1 MiB), avoid `string()` because it will load the entire document into memory. In that case, prefer to process the body as a stream.
