C# java 中對http post傳參數請求

C#中

 //此處為http參數地區，可為普通拼接字串或json,xml等格式       string json ="{\"removeFloatingIp\" : {\"address\": \"172.26.80.118\"}}";       byte[] data = encoding.GetBytes(json);        //此處為為http請求url        var uri = new Uri("http://172.26.80.16:8774/v1.1/1/servers/36");        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);        //用此方法可以添加標準或非標準http請求，諸如conten-type ,accept,range等        request.Headers.Add("X-Auth-Token", HttpUtility.UrlEncode("openstack"));        //此處為C#實現的一些標準http要求標頭添加方法，用上面的方面也可以實現        request.ContentType = "application/json";        request.Accept = "application/xml";       // request.ContentLength = data.Length;        //此處添加標準http請求方面        request.Method = "POST";     System.IO.Stream sm = request.GetRequestStream();       sm.Write(data, 0, data.Length);       sm.Close();        HttpWebResponse response = (HttpWebResponse)request.GetResponse();        Stream streamResponse = response.GetResponseStream();        StreamReader streamRead = new StreamReader(streamResponse, Encoding.UTF8);        Char[] readBuff = new Char[256];        int count = streamRead.Read(readBuff, 0, 256);        //content為http響應所返回的字元流        String content = "";        while (count > 0)        {            String outputData = new String(readBuff, 0, count);            content += outputData;            count = streamRead.Read(readBuff, 0, 256);        }        response.Close();

JAVA中：HttpPost req=new HttpPost("http://172.26.80.15:35357/v2.0/tokens"); StringEntity entity = new StringEntity("{\"auth\":{\"passwordCredentials\":{\"username\": \"admin\", \"password\": \"openstack\"}}}");

//此處的entity可以定義為ByteArrayEntity,用以可以傳任意格式的參數

                 req.setEntity(entity); req.setHeader("Content-type", "application/json"); req.setHeader("X-Auth-Token", "openstack");      HttpResponse httpresponse = new DefaultHttpClient().execute(req);      System.out.println();      try{BufferedReader reader = new BufferedReader(new InputStreamReader(httpresponse.getEntity().getContent())); String line = reader.readLine(); //while (line != null) { //line = reader.readLine(); //} System.out.println(line);}catch (Exception e) {e.printStackTrace();}
