jenkins 执行可执行jar包测试中，请求乱码解决办法

自动化脚本在eclipse中执行，没有问题。jenkins构建打包自动化脚本，在执行脚本时，遇到了脚本中发送的请求的参数为乱码，实现了如下一些解决办法：

1、设置操作系统环境JAVA_TOOL_OPTIONS   = -Dfile.encoding=UTF-8

2、jenkins 系统管理> 系统设置 设置全局变量

3、修改代码，代码中把请求参数在使用前变成uft8 格式。响应输出流也专换成utf-8

para = new String(para.toString().getBytes(), "utf-8");   使用参数

 in = new BufferedReader( new InputStreamReader(conn.getInputStream(),"utf-8"));   响应输出流也专换成utf-8

  public static String sendPost(String url, String param,String wexinsession) {
　　　　para = new String(para.toString().getBytes(), "utf-8"); 
        PrintWriter out = null;
         BufferedReader in = null;
        String result = "";
        try {
            URL realUrl = new URL(url);
            // 打开和URL之间的连接
            URLConnection conn = realUrl.openConnection();
            // 设置通用的请求属性  addRequestHeader("Content-Type","text/html;charset=UTF-8"); 
            conn.setRequestProperty("Content-Type", "text/html;charset=UTF-8");
            conn.setRequestProperty("Host", PropsUtil.readValue("emdsServerHost"));
            conn.setRequestProperty("Accept", "application/json, text/javascript, */*; q=0.01");
            conn.setRequestProperty("Connection", "keep-alive");
            conn.setRequestProperty("X-Requested-With", "XMLHttpRequest");

            conn.setRequestProperty("Content-Length", "700");
            conn.setRequestProperty("Connection", "keep-alive");

            conn.setRequestProperty("Referer", "http://xxx.xxx.xxx/sss.ss");
        
            conn.setRequestProperty("Cookie", wexinsession);
            // 发送POST请求必须设置如下两行
            conn.setDoOutput(true);
            conn.setDoInput(true);
            // 获取URLConnection对象对应的输出流
            out = new PrintWriter(conn.getOutputStream());
            // 发送请求参数
            out.print(param);
            // flush输出流的缓冲
            out.flush();
            // 定义BufferedReader输入流来读取URL的响应
            in = new BufferedReader( new InputStreamReader(conn.getInputStream(),"utf-8"));
            String line;
            while ((line = in.readLine()) != null) {
                result += line;
            }

          //  System.out.println(result);
        } catch (Exception e) {
            System.out.println("发送 POST 请求出现异常！"+e);
            e.printStackTrace();
        }
        //使用finally块来关闭输出流、输入流
        finally{
            try{
                if(out!=null){
                    out.close();
                }
                if(in!=null){
                    in.close();
                }
            }
            catch(IOException ex){
                ex.printStackTrace();
            }
