java实现新浪微博Oauth接口发送图片和文字的方法

本文实例讲述了java实现新浪微博Oauth接口发送图片和文字的方法。分享给大家供大家参考。具体如下：

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，很多人卡在了这一布。现将代码呈上，希望能帮到一些朋友。

/**
* 发表带图片的微博
* @param token
* @param tokenSecret
* @param aFile
* @param status
* @param urlPath
* @return
*/
public String uploadStatus(String token, String tokenSecret, File aFile, String status, String urlPath) {
 httpOAuthConsumer = new DefaultOAuthConsumer(consumerKey,consumerSecret);
 httpOAuthConsumer.setTokenWithSecret(token,tokenSecret);
 String result = null;
 try {
  URL url = new URL(urlPath);
  HttpURLConnection request = (HttpURLConnection) url.openConnection();
  request.setDoOutput(true);
  request.setRequestMethod("POST");
  HttpParameters para = new HttpParameters();
  para.put("status", URLEncoder.encode(status,"utf-8").replaceAll("\\+", "％20"));
  String boundary = "---------------------------37531613912423";
  String content = "--"+boundary+"\r\nContent-Disposition: form-data; name=\"status\"\r\n\r\n";
  String pic = "\r\n--"+boundary+"\r\nContent-Disposition: form-data; name=\"pic\"; filename=\"image.jpg\"\r\nContent-Type: image/jpeg\r\n\r\n";
  byte[] end_data = ("\r\n--" + boundary + "--\r\n").getBytes();
  FileInputStream stream = new FileInputStream(aFile);
  byte[] file = new byte[(int) aFile.length()];
  stream.read(file);
  request.setRequestProperty("Content-Type", "multipart/form-data; boundary="+boundary); //设置表单类型和分隔符
  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
  httpOAuthConsumer.setAdditionalParameters(para);
  httpOAuthConsumer.sign(request);
  OutputStream ot = request.getOutputStream();
  ot.write(content.getBytes());
  ot.write(status.getBytes());
  ot.write(pic.getBytes());
  ot.write(file);
  ot.write(end_data);
  ot.flush();
  ot.close();
  request.connect();
  if (200 == request.getResponseCode()) {
   result = "SUCCESS";
  }
 } catch (FileNotFoundException e1) {
  e1.printStackTrace();
 } catch (IOException e) {
  e.printStackTrace();
 } catch (OAuthMessageSignerException e) {
  e.printStackTrace();
 } catch (OAuthExpectationFailedException e) {
  e.printStackTrace();
 } catch (OAuthCommunicationException e) {
  e.printStackTrace();
 }
 return result;
}

希望本文所述对大家的java程序设计有所帮助。
