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。
