  • Android学习笔记--客户端上传图片到PHP服务器(带PHP端代码)

    本人新手一枚,昨天下午五点多的时候公司让我做一个上传图片,表示一脸蒙蔽,但是还是要很淡定的说好,没问题,下班回家研究弄到了后半夜总算搞定了,今天上午来了把图片上传搞定又做了一些优化,比如质量压缩图片,和缩小尺寸 之后在上传到服务器,下面贴代码

    这里是裁剪图片保存到本地的,方法,scPath是你要上传图片的路径

     1     /**
     2      * 裁剪图片,保存到本地
     3      * @param srcPath
     4      */
     5     private  void compressPicture(String srcPath) {
     6         //上传到服务器的图片名字
     7         long times = System.currentTimeMillis();
     8         //设置图片保存的路径
     9         String dir = Environment.getExternalStorageDirectory().getAbsolutePath() + "/tencent/MicroMsg/WeiXin/"+times+".jpg";
    10         //File一年
    11         file=new File(dir);//将要保存图片的路径
    12         FileOutputStream fos = null;
    13         BitmapFactory.Options op = new BitmapFactory.Options();
    14 
    15         // 开始读入图片,此时把options.inJustDecodeBounds 设回true了
    16         op.inJustDecodeBounds = true;
    17         Bitmap bitmap = BitmapFactory.decodeFile(srcPath, op);
    18         op.inJustDecodeBounds = false;
    19 
    20         // 缩放图片的尺寸
    21         float w = op.outWidth;
    22         float h = op.outHeight;
    23         float hh = 500f;//
    24         float ww = 500f;//
    25         // 最长宽度或高度1024
    26         float be = 1.0f;
    27         if (w > h && w > ww) {
    28             be = (float) (w / ww);
    29         } else if (w < h && h > hh) {
    30             be = (float) (h / hh);
    31         }
    32         if (be <= 0) {
    33             be = 1.0f;
    34         }
    35         op.inSampleSize = (int) be;// 设置缩放比例,这个数字越大,图片大小越小.
    36         // 重新读入图片,注意此时已经把options.inJustDecodeBounds 设回false了
    37         bitmap = BitmapFactory.decodeFile(srcPath, op);
    38         int desWidth = (int) (w / be);
    39         int desHeight = (int) (h / be);
    40         bitmap = Bitmap.createScaledBitmap(bitmap, desWidth, desHeight, true);
    41         try {
    42             fos = new FileOutputStream(dir);
    43             if (bitmap != null) {
    44                 bitmap.compress(Bitmap.CompressFormat.JPEG, 30, fos);
    45             }
    46             //图片保存成功之后调用上传方法
    47             getSetImage();
    48         } catch (FileNotFoundException e) {
    49             e.printStackTrace();
    50         }
    51     }

    上传到服务器的方法 主要是就是调用了一个工具类中的方法,然后通过handler来通知是否成功

     1     /**
     2      * 上传图片到服务器
     3      */
     4     private     void getSetImage(){
     5         System.out.println("图片压缩成功");
     6         Message msg = Message.obtain();
     7         UploadUtil uu = new UploadUtil();
     8         Map<String, String> params = new HashMap<String, String>();
     9         params.put("app_uid", "100017");
    10         try {
    11             String result = uu.doPost(url, params, file);
    12             msg.what = 0;
    13             msg.obj = result;
    14             mHandler.sendMessage(msg);
    15         } catch (Exception e) {
    16             e.printStackTrace();
    17             msg.what = 1;
    18             msg.obj = "图片上传失败";
    19             mHandler.sendMessage(msg);
    20         }
    21     }
      String result = uu.doPost(url, params, file); 
     这句是核心代码 下载来看下

     8      * @throws Exception
     9      */
    10     public String doPost(String url, Map<String, String> param, File file) throws Exception {
    11         HttpPost post = new HttpPost(url);
    12 
    13         HttpClient client = new DefaultHttpClient();
    14         MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
    15         if (param != null && !param.isEmpty()) {
    16             for (Map.Entry<String, String> entry : param.entrySet()) {
    17                 entity.addPart(entry.getKey(), new StringBody(entry.getValue()));
    18 
    19                 Log.e(TAG, "key :: " + entry.getKey() + " | value :: " + entry.getValue());
    20 
    21             }
    22         }
    23         // 上传图片到服务器
    24         if (file != null && file.exists()) {
    25             entity.addPart("uploadedfile", new FileBody(file));
    26         }
    27         post.setEntity(entity);
    28         HttpResponse response = client.execute(post);
    29         int stateCode = response.getStatusLine().getStatusCode();
    30         StringBuffer sb = new StringBuffer();
    31         if (stateCode == HttpStatus.SC_OK) {
    32             HttpEntity result = response.getEntity();
    33             if (result != null) {
    34                 InputStream is = result.getContent();
    35                 BufferedReader br = new BufferedReader(new InputStreamReader(is));
    36                 String tempLine;
    37                 while ((tempLine = br.readLine()) != null) {
    38                     sb.append(tempLine);
    39                 }
    40             }
    41         }
    42         post.abort();
    43         return sb.toString();
    44     }

    270             msg.what = 0;
    271             msg.obj = result;
    272             mHandler.sendMessage(msg);
    273         } catch (Exception e) {

    275             msg.what = 1;
    276             msg.obj = "图片上传失败";
    277             mHandler.sendMessage(msg);
    278         }
    279     }
    280 
    281 
    282 }

     就先这些 上传图片就做完了,PHP代码

     1 <?php
     2 $target = "./upload/";//接受图片的目录
     3 $target_path = $target . basename( $_FILES['uploadedfile']['name']);
     4 //么有目录则创建一个
     5 if (!file_exists($target)){
     6     mkdir($target , 0777);
     7 }
     8 if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
     9     echo "上传成功";
    10 } else {
    11     echo "上传失败";
    12 }
    13 ?>

    把这个放到服务器上,上传的url就是你的服务器地址

    放一张图效果图


    上传完成 看看服务器那边

      


    打开地址试试

    OK已经上传成功了,下载附带一个apk地址,可以上传图片 成功返回图片地址 看看能否打开 如果能就是成功,不能就是失败

    下载地址为:www.aiboyy.pw/images/apk.apk 下载安装即可


    已经完成了 本人新手 说的不够详细,我的目的只是让一些不会用的人会用起来 用起来以后才能继续更深的研究,谢谢大家
