如何使用Android Koush / ion动态形成请求

Question

尝试使用Android离子库将多个图像上传到服务器

 Ion.with(ProgressBarUpload.this)
                        .load(URL)
                        .uploadProgressBar(progressBar)
                        .uploadProgressHandler(new ProgressCallback() {
                            @Override
                            public void onProgress(long downloaded, long total) {
                                uploadCount.setText("" + downloaded + " / " + total);
                            }
                        })
                        .setMultipartFile("uploaded_file", f)
                        .setMultipartParameter("name", "andrew")
                        .asString().setCallback(new FutureCallback<String>() {
                    @Override
                    public void onCompleted(Exception e, String result) {
                        Toast.makeText(getBaseContext(), "" + result, Toast.LENGTH_SHORT).show();
                    }
                });
            }
        });

在此请求中，我需要根据用户选择的图像数量将setMultipartFile("uploaded_file", f)动态添加到请求中

要使文件上传为可选，请将其作为多部分添加，然后动态添加文件部分

ArrayList<Part> filesParts = new ArrayList<>();
fileParts.add(new FilePart("uploaded_file",new File(path))); //dynamically add 

然后将.addMultipartParts(filesParts)添加到请求中
