Creating a proper MultipartBuilder Http Request with OKHttp

Question

ild like to recode my project and use okHttp instead of the default HttpClient implemented in Android.

I\'ve downloaded the latest source of the okhttp-main release.

Answer 1

Uploading file in multipart using OkHttp

private static final String IMGUR_CLIENT_ID = "...";
private static final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");

private final OkHttpClient client = new OkHttpClient();

public void run() throws Exception {
  // Use the imgur image upload API as documented at https://api.imgur.com/endpoints/image
  RequestBody requestBody = new MultipartBuilder()
      .type(MultipartBuilder.FORM)
      .addPart(
          Headers.of("Content-Disposition", "form-data; name=\"title\""),
          RequestBody.create(null, "Square Logo"))
      .addPart(
          Headers.of("Content-Disposition", "form-data; name=\"image\""),
          RequestBody.create(MEDIA_TYPE_PNG, new File("website/static/logo-square.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();
  if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

  System.out.println(response.body().string());
}

This worked for me using okHttp3:

            OkHttpClient client = new OkHttpClient();
            File file = new File(payload);

            RequestBody formBody = new MultipartBody.Builder()
                    .setType(MultipartBody.FORM)
                    .addFormDataPart("file", "image.jpg",
                            RequestBody.create(MediaType.parse("image/jpg"), file))

                    .build();

            Request request = new Request.Builder().url(url).post(formBody).build();

            Response response = client.newCall(request).execute();
            if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

I modified Dr. Enemy's answer:

 MultipartBody.Builder builder =new MultipartBody.Builder().setType(MultipartBody.FORM);

for (Object aMData : dataClass.getData().entrySet()) {
        Map.Entry mapEntry = (Map.Entry) aMData;
        String keyValue = (String) mapEntry.getKey();
        String value = (String) mapEntry.getValue();
        builder.addPart(keyValue, value);
}

for (DataPackage dataPackage : dataClass.getDataPackages()) {
        builder.addPart("upfile[]", dataPackage.getFile());
}

Start adding the formDataPart to builder and at end create RequestBody

RequestBody requestBody = builder.build();

you can perform above actions with

 compile 'com.squareup.okhttp3:okhttp:3.4.1'
