Question

我尝试使用php将图像上传到服务器。但是我收到了以下错误：

引起：java.lang.IllegalArgumentException：索引171处查询中的非法字符：我的服务器名称/ upload.php？sel_bar_code = ab12＆amp; text = hello＆amp; image = [编码图像到base64听到]

我在Android上没有收到此错误。下面是我的代码，它将图像上传到服务器。

if (isImage) {
            imgPreview.setVisibility(View.VISIBLE);
            vidPreview.setVisibility(View.GONE);
            // bimatp factory
            BitmapFactory.Options options = new BitmapFactory.Options();

            // down sizing image as it throws OutOfMemory Exception for larger
            // images
            options.inSampleSize = 8;

            bitmap = BitmapFactory.decodeFile(filePath, options);
            imgPreview.setImageBitmap(bitmap);

            ByteArrayOutputStream ByteStream=new  ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG,100, ByteStream);
            byte [] b=ByteStream.toByteArray();
            image_value=Base64.encodeToString(b, Base64.DEFAULT);

后台流程代码：

protected String doInBackground(Void... params) {
            return uploadFile();
        }

        @SuppressWarnings("deprecation")
        private String uploadFile() {
            String responseString = null;

            HttpClient httpclient = new DefaultHttpClient();
            List<NameValuePair> qparams = new ArrayList<NameValuePair>();
         // These params should ordered in key
            qparams.add(new BasicNameValuePair("sel_bar_code", product_id));

            HttpPost httppost = new HttpPost(Config.FILE_UPLOAD_URL+"sel_bar_code="+product_id+"&text="+text_value +"&image="+image_value);

            try {
                AndroidMultiPartEntity entity = new AndroidMultiPartEntity(
                        new ProgressListener() {

                            @Override
                            public void transferred(long num) {
                                publishProgress((int) ((num / (float) totalSize) * 100));
                            }
                        });

                File sourceFile = new File(filePath);

                // Adding file data to http body
                entity.addPart("image", new FileBody(sourceFile));

                // Extra parameters if you want to pass to server
                entity.addPart("website",
                        new StringBody("www.google.com"));
                entity.addPart("email", new StringBody("info@gmail.com"));

                totalSize = entity.getContentLength();
                httppost.setEntity(entity);

                // Making server call
                HttpResponse response = httpclient.execute(httppost);
                HttpEntity r_entity = response.getEntity();

                int statusCode = response.getStatusLine().getStatusCode();
                if (statusCode == 200) {
                    // Server response
                    responseString = EntityUtils.toString(r_entity);
                } else {
                    responseString = "Error occurred! Http Status Code: "
                            + statusCode;
                }

            } catch (ClientProtocolException e) {
                responseString = e.toString();
            } catch (IOException e) {
                responseString = e.toString();
            }

            return responseString;

        }

Answer 1

昨天我开发了相同的流程...

我的应用程序的差异需要逐个发送照片。另一方面，我发送图像字节为String，最后我遇到了Base64压缩问题，因为标志'Base64.DEFAULT'在我的情况下在字符串中添加了intros。我使用标志'Base64.NO_WRAP'来解决这个问题。为了省略此问题，您需要在发送之前将文件复制到公共目录以验证文件是否已损坏。
服务器具有可以发送的低大小文件也是可行的，服务器部分限制了接收文件的大小。

如果我能帮助你告诉我和好的节目！
