Android编程：新浪微博采用Oauth发送图片和文字

 当前基于移动设计编程吸引了大量的编程人员，今天我就说说Android下发送图片和文字的问题...
基于网上很多人利用新浪api开发新浪微博客户端的时候遇到无法发图片的问题，很多人卡在了这一步。
现将代码呈上，希望能帮到一些朋友。
1 /**  2      * 发表带图片的微博  3      * @param token  4      * @param tokenSecret  5      * @param aFile     要上传的图片文件 6      * @param status    要发表的微博文字 7      * @param urlPath   对应的api地址 8      * @return  9      */  10     public String uploadStatus(String token, String tokenSecret, File aFile, String status, String urlPath) {  11         httpOAuthConsumer = new DefaultOAuthConsumer(consumerKey,consumerSecret);  12         httpOAuthConsumer.setTokenWithSecret(token,tokenSecret);  13         String result = null;  14         try {  15             URL url = new URL(urlPath);  16             HttpURLConnection request = (HttpURLConnection) url.openConnection();  17             request.setDoOutput(true);  18             request.setRequestMethod("POST");  19             HttpParameters para = new HttpParameters();  20             para.put("status", URLEncoder.encode(status,"utf-8").replaceAll("\\+", "%20"));  21             String boundary = "---------------------------37531613912423";  22             String content = "--"+boundary+"\r\nContent-Disposition: form-data; name=\"status\"\r\n\r\n";  23             String pic = "\r\n--"+boundary+"\r\nContent-Disposition: form-data; name=\"pic\"; filename=\"image.jpg\"\r\nContent-Type: image/jpeg\r\n\r\n";  24             byte[] end_data = ("\r\n--" + boundary + "--\r\n").getBytes();   25             FileInputStream stream = new FileInputStream(aFile);  26             byte[] file = new byte[(int) aFile.length()];  27             stream.read(file);  28             request.setRequestProperty("Content-Type", "multipart/form-data; boundary="+boundary); //设置表单类型和分隔符   29             request.setRequestProperty("Content-Length", String.valueOf(content.getBytes().length + status.getBytes().length + pic.getBytes().length + aFile.length() + end_data.length)); //设置内容长度 　　　　　　　　　　//下面的步骤是对请求进行签名。  30             httpOAuthConsumer.setAdditionalParameters(para);  31             httpOAuthConsumer.sign(request);  32             OutputStream ot = request.getOutputStream();  33             ot.write(content.getBytes());  34             ot.write(status.getBytes());  35             ot.write(pic.getBytes());  36             ot.write(file);  37             ot.write(end_data);  38             ot.flush();  39             ot.close();  40             request.connect();  41             if (200 == request.getResponseCode()) {  42                 result = "SUCCESS";  43             }  44         } catch (FileNotFoundException e1) {  45             e1.printStackTrace();  46         } catch (IOException e) {  47             e.printStackTrace();  48         } catch (OAuthMessageSignerException e) {  49             e.printStackTrace();  50         } catch (OAuthExpectationFailedException e) {  51             e.printStackTrace();  52         } catch (OAuthCommunicationException e) {  53             e.printStackTrace();  54         }  55         return result;  56     }
