# Recipes

We've written some recipes that demonstrate how to solve common problems with OkHttp. Read through them to learn about how everything works together. Cut-and-paste these examples freely; that's what they're for.

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

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

constraints.Max.message = {item} は {value} 以下にしてください。
constraints.Min.message = {item} は {value} 以上にしてください。
constraints.NotNull.message = {item} は未入力です。
constraints.Null.message = {item} は null でなければなりません。
constraints.Past.message = {item} は過去の値にする必要があります。
constraints.Pattern.message = {item} が 「{regexp}」 に一致しません。
constraints.Size.message = {item}のサイズは {min} 文字から {max} 文字の範囲にしてください。

  (`I only wish it was,' the March Hare said to itself in a
whisper.)

  `That would be grand, certainly,' said Alice thoughtfully:
`but then--I shouldn't be hungry for it, you know.'

  `Not at first, perhaps,' said the Hatter:  `but you could keep
it to half-past one as long as you liked.'

 *  **This release deletes the long-deprecated `OkUrlFactory` and `OkApacheClient` APIs.** These
    facades hide OkHttp's implementation behind another client's API. If you still need this please
    copy and paste [ObsoleteUrlFactory.java][obsolete_url_factory] or
    [ObsoleteApacheClient.java][obsolete_apache_client] into your project.

 *  **OkHttp now supports duplex calls over HTTP/2.** With normal HTTP calls the request must finish

- Fixed the wrong hierarchical structure for both the child span and the parent span (i.e. `SerializeObject` and `List`). In the past, some children's spans appeared parallel to their parents.
