OkHttp ate MimeCraft

Last year, during Square's 7 days of open source, we announced Mime Craft, which makes it easy to build browser-style HTTP request bodies.

With this week's OkHttp 2 release candidate, we've promoted that MimeCraft code into OkHttp itself. You can encode a form request:

RequestBody formBody = new FormEncodingBuilder()
  .add("search", "Jurassic Park")
  .build();
Request request = new Request.Builder()
  .url("https://en.wikipedia.org/w/index.php")
  .post(formBody)
  .build();

Response response = client.newCall(request).execute();

Or a multipart request:

RequestBody requestBody = new MultipartBuilder()
  .type(MultipartBuilder.FORM)
  .addPart(
    Headers.of("Content-Disposition", "form-data; name=title"),
    RequestBody.create(null, "Logo"))
  .addPart(
    Headers.of("Content-Disposition", "form-data; name=image"),
    RequestBody.create(MEDIA_TYPE_PNG, new File("logo.png")))
  .build();
    
Request request = new Request.Builder()
  .header("Authorization", "Client-ID " + IMGUR_CLIENT_ID)
  .url("https://api.imgur.com/3/image")
  .post(requestBody)
  .build();

Response response = client.newCall(request).execute();

It's quite satisfying to build a multipart RequestBody from other RequestBody values. Yo dawg.

Complete examples are on the OkHttp recipes page.
