将图像转换为文件并发送到 volley 和 json url

Question

我正在尝试使用 Volley 使用图像和其他详细信息更新个人资料。

我必须转换图像文件并将其作为参数发送到 url。

我还必须解析所有其他详细信息以更新配置文件。

如何更新个人资料图片？

               url = "http://192.168.1.30:1021/mobileapi/profile_update.html?&user_id="+user+"&firstname="+First.getText().toString()+

                        "&phonemobile="+mob.getText().toString()+"&aboutus="+work.getText().toString()+"&phonework="+phone.getText().toString()+
                        "&skypeid="+skypeid.getText().toString()+"&gender="+gender+"&smtp_password="+mpass.getText().toString()+"&image="+fos;

                url=url.trim().replaceAll("\\s+","");
                System.out.println("url" + url);

使用此代码..它适用于我。它发送多部分图像。

 private void saveProfileDetails() {
    // loading or check internet connection or something...
    // ... then
    String url = "http://51.76.27.90:8080/post/new/";
    VolleyMultipartRequest multipartRequest = new VolleyMultipartRequest(Request.Method.POST, url, new Response.Listener<NetworkResponse>() {
        @Override
        public void onResponse(NetworkResponse response) {
            System.out.println("statuscode is " + response.statusCode);
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            NetworkResponse networkResponse = error.networkResponse;
            String errorMessage = "Unknown error";
            if (networkResponse == null) {
                if (error.getClass().equals(TimeoutError.class)) {
                    errorMessage = "Request timeout";
                } else if (error.getClass().equals(NoConnectionError.class)) {
                    errorMessage = "Failed to connect server";
                }
            } else {
                String result = new String(networkResponse.data);
                try {
                    JSONObject response = new JSONObject(result);
                    String status = response.getString("status");
                    String message = response.getString("message");

                    Log.e("Error Status", status);
                    Log.e("Error Message", message);

                    if (networkResponse.statusCode == 404) {
                        errorMessage = "Resource not found";
                    } else if (networkResponse.statusCode == 401) {
                        errorMessage = message + " Please login again";
                    } else if (networkResponse.statusCode == 400) {
                        errorMessage = message + " Check your inputs";
                    } else if (networkResponse.statusCode == 500) {
                        errorMessage = message + " Something is getting wrong";
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
            Log.i("Error", errorMessage);
            error.printStackTrace();
        }
    }) {
        @Override
        protected Map<String, String> getParams() {
            Map<String, String> params = new HashMap<>();
            params.put("username", "a@a.com");
            params.put("category", "product");
            params.put("type", "product");
            params.put("title", "i am done ");
            params.put("content", "contentssssssssssssssssssssssss");
            params.put("location", "Bangalore");

            return params;
        }

        @Override
        protected Map<String, DataPart> getByteData() {
            Map<String, DataPart> params = new HashMap<>();
            // file name could found file base or direct access from real path
            // for now just get bitmap data from ImageView
            params.put("imageC", new DataPart("file_avatar.jpg", AppClass.getFileDataFromDrawable(getBaseContext(), colorImage.getDrawable()), "image/jpeg"));
            params.put("imageBW", new DataPart("file_cover.jpg", AppClass.getFileDataFromDrawable(getBaseContext(), blackAndWhiteImage.getDrawable()), "image/jpeg"));

            return params;
        }
    };

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

这是你的 VollySingleton 函数
