java实现新浪微博Oauth接口发送图片和文字的方法

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。
