Android应用中拍照后获取照片路径并上传的实例分享

Activity 中的代码，我只贴出重要的事件部分代码

public void doPhoto(View view) 
{ 
  destoryBimap(); 
  String state = Environment.getExternalStorageState(); 
  if (state.equals(Environment.MEDIA_MOUNTED)) { 
    Intent intent = new Intent("Android.media.action.IMAGE_CAPTURE"); 
    startActivityForResult(intent, 1); 
  } else { 
    Toast.makeText(MainActivity.this, "没有SD卡", Toast.LENGTH_LONG).show(); 
  } 
} 
@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{ 
  Uri uri = data.getData(); 
  if (uri != null) { 
    this.photo = BitmapFactory.decodeFile(uri.getPath()); 
  } 
  if (this.photo == null) { 
    Bundle bundle = data.getExtras(); 
    if (bundle != null) { 
      this.photo = (Bitmap) bundle.get("data"); 
    } else { 
      Toast.makeText(MainActivity.this, "拍照失败", Toast.LENGTH_LONG).show(); 
      return; 
    } 
  } 
  FileOutputStream fileOutputStream = null; 
  try { 
    // 获取 SD 卡根目录 
    String saveDir = Environment.getExternalStorageDirectory() + "/meitian_photos"; 
    // 新建目录 
    File dir = new File(saveDir); 
    if (! dir.exists()) dir.mkdir(); 
    // 生成文件名 
    SimpleDateFORMat t = new SimpleDateFormat("yyyyMMddssSSS"); 
    String filename = "MT" + (t.format(new Date())) + ".jpg"; 
    // 新建文件 
    File file = new File(saveDir, filename); 
    // 打开文件输出流 
    fileOutputStream = new FileOutputStream(file); 
    // 生成图片文件 
    this.photo.compress(Bitmap.CompressFormat.JPEG, 100, fileOutputStream); 
    // 相片的完整路径 
    this.picPath = file.getPath(); 
    ImageView imageView = (ImageView) findViewById(R.id.showPhoto); 
    imageView.setImageBitmap(this.photo); 
  } catch (Exception e) { 
    e.printStackTrace(); 
  } finally { 
    if (fileOutputStream != null) { 
      try { 
        fileOutputStream.close(); 
      } catch (Exception e) { 
        e.printStackTrace(); 
      } 
    } 
  } 
} 
 
private void destoryBimap() 
{ 
  if (photo != null && ! photo.isRecycled()) { 
    photo.recycle(); 
    photo = null; 
  } 
}

其中的上传工具类我们下面一起来看：
Android 发送HTTP GET POST 请求以及通过 MultipartEntityBuilder 上传文件

全部使用新的方式 MultipartEntityBuilder 来处理了。

在 Activity 中的使用方法（这里我还是只写主体部分代码）：
MainActivity.java

public void doClick(View view) 
{ 
  ZHttpRequest get = new ZHttpRequest(); 
  get 
      .setCharset(HTTP.UTF_8) 
      .setConnectionTimeout(5000) 
      .setSoTimeout(5000); 
  get.setOnHttpRequestListener(new ZHttpRequest.OnHttpRequestListener() { 
    @Override 
    public void onRequest(ZHttpRequest request) throws Exception { 
    } 
    @Override 
    public String onSucceed(int statusCode, ZHttpRequest request) throws Exception { 
      return request.getInputStream(); 
    } 
    @Override 
    public String onFailed(int statusCode, ZHttpRequest request) throws Exception { 
      return "GET 请求失败：statusCode "+ statusCode; 
    } 
  }); 
  ZHttpRequest post = new ZHttpRequest(); 
  post 
      .setCharset(HTTP.UTF_8) 
      .setConnectionTimeout(5000) 
      .setSoTimeout(10000); 
  post.setOnHttpRequestListener(new ZHttpRequest.OnHttpRequestListener() { 
    private String CHARSET = HTTP.UTF_8; 
    private ContentType TEXT_PLAIN = ContentType.create("text/plain", Charset.forName(CHARSET)); 
    @Override 
    public void onRequest(ZHttpRequest request) throws Exception { 
      // 设置发送请求的 header 信息 
      request.addHeader("cookie", "abc=123;456=爱就是幸福;"); 
      // 配置要 POST 的数据 
      MultipartEntityBuilder builder = request.getMultipartEntityBuilder(); 
      builder.addTextBody("p1", "abc"); 
      builder.addTextBody("p2", "中文", TEXT_PLAIN); 
      builder.addTextBody("p3", "abc中文cba", TEXT_PLAIN); 
      if (picPath != null && ! "".equals(picPath)) { 
        builder.addTextBody("pic", picPath); 
        builder.addBinaryBody("file", new File(picPath)); 
      } 
      request.buildPostEntity(); 
    } 
    @Override 
    public String onSucceed(int statusCode, ZHttpRequest request) throws Exception { 
      return request.getInputStream(); 
    } 
    @Override 
    public String onFailed(int statusCode, ZHttpRequest request) throws Exception { 
      return "POST 请求失败：statusCode "+ statusCode; 
    } 
  }); 
  TextView textView = (TextView) findViewById(R.id.showContent); 
  String content = "初始内容"; 
  try { 
    if (view.getId() == R.id.doGet) { 
      content = get.get("http://www.baidu.com"); 
      content = "GET数据：isGet: " + (get.isGet() ? "yes" : "no") + " =>" + content; 
    } else { 
      content = post.post("http://192.168.1.6/test.PHP"); 
      content = "POST数据：isPost" + (post.isPost() ? "yes" : "no") + " =>" + content; 
    } 
  } catch (IOException e) { 
    content = "IO异常：" + e.getMessage(); 
  } catch (Exception e) { 
    content = "异常：" + e.getMessage(); 
  } 
  textView.setText(content); 
} 

其中 picPath 为 SD 卡中的图片路径 String 类型，我是直接拍照后进行上传用的

至于服务端我用的 php ，只是简单的输出获取到的数据而已

<?php 
echo 'GET:<br>'. "\n"; 
//print_r(array_map('urldecode', $_GET)); 
print_r($_GET); 
echo '<br>'. "\n". 'POST:<br>'. "\n"; 
//print_r(array_map('urldecode', $_POST)); 
print_r($_POST); 
echo '<br>'. "\n". 'FILES:<br>'. "\n"; 
print_r($_FILES); 
echo '<br>'. "\n". 'COOKIES:<br>'. "\n"; 
print_r($_COOKIE);
