使用okHttp上传图片 [英] Image upload using okHttp

问题描述

我想使用 okhttp 上传图片，但我找不到用于 Post Image 的 MultipartBuilder.我可以用什么来代替它.

i want to upload image using okhttp but i am not able to find MultipartBuilder for Post Image.What can i use instead of this.

这是我的代码

public static JSONObject uploadImage(File file) {

    try {

        final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");

        RequestBody req = new MultipartBuilder().setType(MultipartBody.FORM)
            .addFormDataPart("userid", "8457851245")
            .addFormDataPart(
                "userfile",
                "profile.png",
                RequestBody.create(MEDIA_TYPE_PNG, file)
            )
            .build();

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

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

        Log.d("response", "uploadImage:" + response.body().string());

        return new JSONObject(response.body().string());

    } catch (UnknownHostException | UnsupportedEncodingException e) {
        Log.e(TAG, "Error: " + e.getLocalizedMessage());
    } catch (Exception e) {
        Log.e(TAG, "Other Error: " + e.getLocalizedMessage());
    }
    return null;
}

提前致谢.
