安卓中，对图片用表单上传方式去上传到服务器，一直都是我心中的痛....开始的时候，在上传文本的http请求服务器的方式去提交，提交图片失败，后来，使用了第三方的框架去做这个事情成功了，再后来，回归到自己用原生的代码去写这个提交图片，今天当是做一个总结吧。把一件重要的事情记录下来，给它画上句号吧。

图片表单上传方法：

1、

// modified by LPY//表单方式上传图片及其它参数private void doUploadImage() {try {String url = RequestUrl.BASE_WEB_URL + "imageupload.do?";HttpClient client = new DefaultHttpClient();HttpPost post = new HttpPost(url);ContentBody fileBody = new FileBody(photoFile, "image/jpeg");MultipartEntity entity = new MultipartEntity();// TODO : mobile字符串该则么传要确认下entity.addPart("mobile", new StringBody(mobile));entity.addPart("key", new StringBody("WZDFKYT++"));entity.addPart("file", fileBody);post.setEntity(entity);HttpResponse response = client.execute(post);int statusCode = response.getStatusLine().getStatusCode();if (statusCode == HttpStatus.SC_OK) {String result = EntityUtils.toString(response.getEntity(), "utf-8");JSONObject jsonObject = new JSONObject(result);logo = jsonObject.getString("path");Log.i("LPY_DEBUG","拍照后上传返回的网络图片路径logo =  " + logo);Message msg = new Message();msg.what = jsonObject.getInt("result");msg.obj = jsonObject.getString("path");bindhandler.sendMessage(msg);} else {bindhandler.sendEmptyMessage(-1);}client.getConnectionManager().shutdown();} catch (Exception e) {bindhandler.sendEmptyMessage(-1);// e.printStackTrace();}}private Handler bindhandler = new Handler() {public void handleMessage(android.os.Message msg) {// progressDialog.dismiss();if (msg.what == 1) {}}}；

2、把方法提取出来

/** * 提交参数里有文件的数据 *  * @param url *            服务器地址 * @param param *            参数 * @return 服务器返回结果 * @throws Exception */public static String uploadSubmit(String url, Map<String, String> param,File file) throws Exception {HttpPost post = new HttpPost(url);MultipartEntity entity = new MultipartEntity();if (param != null && !param.isEmpty()) {for (Map.Entry<String, String> entry : param.entrySet()) {if (entry.getValue() != null&& entry.getValue().trim().length() > 0) {entity.addPart(entry.getKey(),new StringBody(entry.getValue()));}}}// 添加文件参数if (file != null && file.exists()) {entity.addPart("file", new FileBody(file));}post.setEntity(entity);HttpResponse response = httpClient.execute(post);int stateCode = response.getStatusLine().getStatusCode();StringBuffer sb = new StringBuffer();if (stateCode == HttpStatus.SC_OK) {HttpEntity result = response.getEntity();if (result != null) {InputStream is = result.getContent();BufferedReader br = new BufferedReader(new InputStreamReader(is));String tempLine;while ((tempLine = br.readLine()) != null) {sb.append(tempLine);}}}post.abort();return sb.toString();}
