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+"rnContent-Disposition: form-data; name="status"rnrn"; String pic = "rn--"+boundary+"rnContent-Disposition: form-data; name="pic"; filename="image.jpg"rnContent-Type: image/jpegrnrn"; byte[] end_data = ("rn--" + boundary + "--rn").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。
