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(); } } } } /** * 销毁图片文件 */ 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。

httpmime-4.3.2.jar

httpcore-4.3.1.jar

有些镜像貌似打不开，页面上可以可以选择国内的 .cn 后缀的域名镜像服务器来下载

直接上代码了：

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() ") + " =>" + content; } else { content = post.post("http://192.168.1.6/test.php"); content = "POST数据：isPost" + (post.isPost() ") + " =>" + 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);
