android上传图片和参数（属性）到服务器

先说明一下环境：

服务器是java ee 的servlet

客户端是android

客户端的核心代码：需要导入apache-mime4j-0.6和httpmime-4.0两个包。。。

  // 上传图片到服务器        HttpPost httpPost = new HttpPost(urlsString);     // 设置传递参数            MultipartEntity reqEntity = new MultipartEntity();            if (!file1.getAbsoluteFile().equals(""))            {                FileBody fileBody = new FileBody(file1);                reqEntity.addPart("pic", fileBody);            }            StringBody type = new StringBody("wish");            reqEntity.addPart("type", type);            if( type.equals("wish") )            {                StringBody temp = new StringBody(iWishID + "");                reqEntity.addPart("temp", temp);            }            else            {                StringBody temp = new StringBody(sUserName);                reqEntity.addPart("temp", temp);            }            httpPost.setEntity(reqEntity);            // 取得默认的HttpClient            HttpClient httpclient = new DefaultHttpClient();            // 取得HttpResponse            HttpResponse httpResponse = httpclient.execute(httpPost);            // HttpStatus.SC_OK表示连接成功            if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK)            {                // 取得返回的字符串                String strResult = EntityUtils.toString(httpResponse.getEntity());                System.out.println("yes!");            }            else            {                System.out.println("no!");            }

服务器的接收代码（POST）：需要commons-io.jar和commons-io.jar第三方包

 protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {          boolean isMultipart = ServletFileUpload.isMultipartContent(request);          if (isMultipart) {              FileItemFactory factory = new DiskFileItemFactory();              ServletFileUpload upload = new ServletFileUpload(factory);              try {                  List items = upload.parseRequest(request);                  Iterator iter = items.iterator();                  while (iter.hasNext()) {                      FileItem item = (FileItem) iter.next();                      if (item.isFormField()) {                          //普通文本信息处理                          String paramName = item.getFieldName();                          String paramValue = item.getString();                          System.out.println(paramName + ":" + paramValue);                      } else {                          //上传文件信息处理                          String fileName = item.getName();                          byte[] data = item.get();                          String filePath = getServletContext().getRealPath("/files") + "/" + fileName;                          FileOutputStream fos = new FileOutputStream(filePath);                          fos.write(data);                          fos.close();                      }                  }              } catch (FileUploadException e) {                  e.printStackTrace();              }          }          response.getWriter().write("UPLOAD_SUCCESS");      }
