本文實例講述了java實現新浪微博Oauth接口發送圖片和文字的方法。分享給大家供大家參考。具體如下：
基於網上很多人利用新浪api開發新浪微博客戶端的時候遇到無法發圖片的問題，很多人卡在了這一布。現將代碼呈上，希望能幫到一些朋友。
/*** 發錶帶圖片的微博* @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); //設置表單類型和分隔符request.setRequestProperty("Content- Length", String.valueOf(content.getBytes().length + status.getBytes().length + pic.getBytes().length + aFile.length() + end_data.length)); //設置內容長度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;}希望本文所述對大家的java程序設計有所幫助。
