如何使用Volley使用多部分/表单数据上传文件

Question

我的一个API使用multipart/form-data在请求正文中上传文件和文本。如何像Postman这样编码？

Answer 1

VolleyMultipartRequest multipartRequest = new VolleyMultipartRequest(Request.Method.POST, url, new Response.Listener<NetworkResponse>() {
    @Override
    public void onResponse(NetworkResponse response) {
        String resultResponse = new String(response.data);

    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {                
        error.printStackTrace();
    }
}) {
    @Override
    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<>();
        params.put("api_token", "gh659gjhvdyudo973823tt9gvjf7i6ric75r76");
        params.put("name", "Angga");
        return params;
    }

    @Override
    protected Map<String, DataPart> getByteData() {
        Map<String, DataPart> params = new HashMap<>();
        params.put("imageName", new DataPart("file_image.jpg", AppHelper.getFileDataFromDrawable(getBaseContext(), mAvatarImage.getDrawable()), "image/jpeg"));
        return params;
    }
};

VolleySingleton.getInstance(getBaseContext()).addToRequestQueue(multipartRequest);
