How is it possible to append params to an OkHttp Request.builder?
//request
Request.Builder requestBuilder = new Request.Builder()
.url(url);
You can use this lib: https://github.com/square/mimecraft:
FormEncoding fe = new FormEncoding.Builder()
.add("name", "Lorem Ipsum")
.add("occupation", "Filler Text")
.build();
Multipart content:
Multipart m = new Multipart.Builder()
.addPart(new Part.Builder()
.contentType("image/png")
.body(new File("/foo/bar/baz.png"))
.build())
.addPart(new Part.Builder()
.contentType("text/plain")
.body("The quick brown fox jumps over the lazy dog.")
.build())
.build();
