新浪微博采用Oauth发送图片和文字

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";
	        }
