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";女装品牌排行榜
