	//创建httpclient对象
    HttpClient httpClient = new HttpClient();

    //创建http发送方式
    HttpPost httpPost = new HttpPost(url);
    //创建发送实体，KV结构
    MutipartEntity reqEntity = new MutipartEntity();
    File myfile = new File("\\xx\xx\x.jpg");
    FileBody fileContent = new FileBody(myfile);
    
    reqEntity.addPart("myfile",fileContent);
    StringBody content = new StringBody("sss.jpg", charset);
    reqEntity.addPart("token", contenttoken);
    
    httppost.setEntity(reqEntity);
    //执行httppost对象
    HtttpResponse reponse = httpClient.execute(httppost);
    HttpEntity resEntity = response.getEntity();
    
    String resString = EntityUtils.toString(resEntity);
