无法使用Java中的okHTTP多部分格式数据为我的android应用程序重新创建cURL POST请求

Question

我已经尝试了两天，现在了解如何复制一个curl请求，以添加一个图像到我的Craftar图像识别集合。我能够创建一个项目，但设置多部分数据代码的方法让我失败了。Craftar只提供如何发布图像文件以将其附加到集合项的cURL语句。

我尝试使用RequestB.in和Postman来查看在消息传输中可以看到的内容，但是okHTTP方法的组合似乎无法解决这个问题。我被难倒了。我尝试了“image/png”和“application/octet-stream”作为我的媒体类型。当我使用Postman发送测试请求时，RequestB.in显示了“application/octet-stream”。下面是它显示的消息信息。

下面是我试图用Java复制的cURL语句。

curl-x POST'https://my.craftar.net/api/v0/image/api_key=123456789abcdefghijk123456789abcdefghijk'-f“item=/api/v0/item/d05924dde1784787a3d6b815e2b1cd69/”-f“file=@back_cover.jpg”

下面是我的代码：

        public class OkHttpHandler extends AsyncTask<String, Void, String> {

        OkHttpClient client = new OkHttpClient();

        @Override
        protected String doInBackground(String... params) {

            File storageDir = Environment.getExternalStoragePublicDirectory(
                    Environment.DIRECTORY_PICTURES);
            File file = new File("/storage/emulated/0/Pictures/BlissBotSenderImages/kaytiandkristoffer.jpg");
            RequestBody requestBody = new MultipartBody.Builder()
                    .setType(MultipartBody.FORM)
                    .addFormDataPart("item", "/api/v0/item/d05924dde1784787a3d6b815e2b1cd69/")
                    .addFormDataPart("file","kaytiandkristoffer.jpg",
                    (RequestBody.create (MEDIA_TYPE_PNG, file)))
                    .build();

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

            try {
                Response response = client.newCall(request).execute();
                return response.body().string();
            } catch (Exception e) {
                e.printStackTrace();
            }

正如有时发生的那样，问题出在别处。在这一行的某个地方，我意外地在endpoint地址中插入了一个无关的字符。我修复了这一点，上面的代码工作只是查找。
