Android 前端之家
前端之家收集整理的这篇文章主要介绍了java – 如何通过在android中捕获到php来保存图像？，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

我们已经尝试了Android和PHP的这个代码.请看下面的代码.

Android的

  1. Scn.setOnClickListener(new OnClickListener() {
  2.             @Override
  3.             public void onClick(View v) {
  4.                 // TODO Auto-generated method stub
  5.                         // Open default camera
  6.                 Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  8.                 // start the image capture Intent
  9.                 startActivityForResult(intent,100);
  10.             }
  11.  }
  12.   protected void onActivityResult(int requestCode,int resultCode,Intent intent) {
  13.             if (requestCode == 100 && resultCode == RESULT_OK) {
  16.                  selectedImage = intent.getData();
  17.                     imageBitmap = (Bitmap) intent.getExtras().get("data");
  19.                 ByteArrayOutputStream baos = new ByteArrayOutputStream();
  20.                 imageBitmap.compress(Bitmap.CompressFormat.JPEG,40,baos);
  22.                 imageView1.setImageBitmap(imageBitmap);

  244.         }
  245. }

它返回解析字节串.它的价值太长了.

PHP

  1.  $base=$Data['images'];
  2.  $binary=base64_decode($base);
  3.  header('Content-Type: bitmaps; charset=utf-8');
  4.  header("Content-Length: " . mb_strlen($base,'8bit'));
  5.  $file = fopen('qr_code.jpeg','wb');
  6.  fwrite($file,$binary);
  7.  fclose($file);
  8.  echo 'Image upload complete!!,Please check your PHP file directory';

以上代码正在运行.但它有一些问题.图像在文件夹中成功保存,但图像将显示为已损坏.我们如何解决这个问题.

提前致谢.

最佳答案
请尝试此代码,此代码适合我.

  1. PHP
  3. // Path to move uploaded files
  4. $target_path = "uploads/";
  6. // array for final json respone
  7. $response = array();
  9. // getting server ip address
  10. $server_ip = gethostbyname(gethostname());
  12. // final file url that is being uploaded
  13. $file_upload_url = 'http://' . $server_ip . '/' . '/xyz/' . '/' . $target_path;
  16. if (isset($_FILES['image']['name'])) {
  17.     $target_path = $target_path . basename($_FILES['image']['name']);
  19.     // reading other post parameters
  20.     $email = isset($_POST['email']) ? $_POST['email'] : '';
  21.     $website = isset($_POST['website']) ? $_POST['website'] : '';
  23.     $response['file_name'] = basename($_FILES['image']['name']);
  24.     $response['email'] = $email;
  25.     $response['website'] = $website;
  27.     try {
  28.         // Throws exception incase file is not being moved
  29.         if (!move_uploaded_file($_FILES['image']['tmp_name'],$target_path)) {
  30.             // make error flag true
  31.             $response['error'] = true;
  32.             $response['message'] = 'Could not move the file!';
  33.         }
  35.         // File successfully uploaded
  36.         $response['message'] = 'File uploaded successfully!';
  37.         $response['error'] = false;
  38.         $response['file_path'] = $file_upload_url . basename($_FILES['image']['name']);
  39.     } catch (Exception $e) {
  40.         // Exception occurred. Make error flag true
  41.         $response['error'] = true;
  42.         $response['message'] = $e->getMessage();
  43.     }
  44. } else {
  45.     // File parameter is missing
  46.     $response['error'] = true;
  47.     $response['message'] = 'Not received any file!F';
  48. }
  50. // Echo final json response to client
  51. echo json_encode($response);
  52. ?>
