[开发测试]java模仿postman中body传值raw写法

public static String COM_GetProject(String crsCOMGetProjectUrl){
   	 URL url = null;
   	OutputStreamWriter out;
    BufferedReader in = null;
    String result = "";
        HttpURLConnection conn = null;
        try {
            //得到访问地址的URL
            url = new URL(crsCOMGetProjectUrl);
            //得到网络访问对象java.net.HttpURLConnection
            conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");
            conn.addRequestProperty("Content-Type", "application/json");
            conn.setRequestProperty("accept", "*/*");
            conn.setRequestProperty("connection", "Keep-Alive");
            conn.setRequestProperty("user-agent",
                    "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
            // 发送POST请求必须设置如下两行
            conn.setDoOutput(true);
            conn.setDoInput(true);
   
            conn.connect();
            out = new OutputStreamWriter( conn.getOutputStream(),"UTF-8");// utf-8编码

            out.write("{}");
