我在使用Grails和SpringSecurity进行后端发送POST时遇到了一些问题。
我不知道为什么，但是当我发送ROLE_ADMIN方法时，它不起作用。我尝试对用户和密码进行编码，然后将其设置在请求 header 上，并尝试相同但不进行编码。
我真的开始对这个问题感到绝望。
这是我的POST代码:

public String POST2(String targetURL, String urlParameters, String user, 
            String clave) { 
        URL url; 
        String h = "http://"; 
        String u = h+targetURL; 
 
        HttpURLConnection connection = null; 
        try { // Create connection // 
            // targetURL = URLEncoder.encode(targetURL, "UTF-8"); 
            url = new URL(u); 
            connection = (HttpURLConnection) url.openConnection(); // cambiarlo 
                                                                    // luego al 
                                                                    // usuario q 
            String login = user + ":" + clave; 
            String encoding = new String(org.apache.commons.codec.binary.Base64 // 
                    .encodeBase64(org.apache.commons.codec.binary.StringUtils // 
                            .getBytesUtf8(login))); 
 
            connection.setRequestMethod("POST"); 
            connection.setRequestProperty("Authorization", "Basic " + login); 
            connection.setRequestProperty("Content-Type", "plain/text");// hace 
                                                                        // // q 
            // sirva // con // el // string // de // json 
 
            connection.setRequestProperty("Content-Length", 
                    "" + Integer.toString(urlParameters.getBytes().length)); 
            connection.setRequestProperty("Content-Language", "en-US"); 
 
            connection.setUseCaches(false); 
            connection.setDoInput(true); 
            connection.setDoOutput(true); 
            connection.setReadTimeout(120000); // Send 
            DataOutputStream wr = new DataOutputStream( 
                    connection.getOutputStream()); 
            wr.writeBytes(urlParameters); 
            wr.flush(); 
            wr.close(); 
 
            // Get Response  
            InputStream is = connection.getInputStream(); 
            BufferedReader rd = new BufferedReader(new InputStreamReader(is)); 
            String line; 
            StringBuffer response = new StringBuffer(); 
            this.setResponseCode(connection.getResponseCode()); 
            while ((line = rd.readLine()) != null) { 
                response.append(line); 
                response.append('\r'); 
            } 
            rd.close(); 
            return response.toString(); 
 
        } catch (Exception e) { 
 
            e.printStackTrace(); 
            return null; 
 
        } finally { 
 
            if (connection != null) { 
                connection.disconnect(); 
            } 
        } 
    } 

private class EntrenadorExecutioner extends AsyncTask<String, Void, String> { 
        private EntrenadorActivity activity = null; 
 
        public EntrenadorExecutioner(EntrenadorActivity activity) { 
            attach(activity); 
        } 
 
        private void attach(EntrenadorActivity activity) { 
            this.activity = activity; 
        } 
 
        @Override 
        protected void onPreExecute() { 
            super.onPreExecute(); 
            activity.startLoader(); 
        } 
 
        @Override 
        protected String doInBackground(String... params) { 
            String json = ""; 
 
            JSONObject jsonObject = new JSONObject(); 
 
            try { 
                jsonObject.accumulate("cedula", params[0]); 
                jsonObject.accumulate("nombre", params[1]); 
                jsonObject.accumulate("primerApellido", params[2]); 
                jsonObject.accumulate("segundoApellido", params[3]); 
 
                json = jsonObject.toString(); 
            } catch (JSONException je) { 
                je.printStackTrace(); 
            } 
 
            return rh.POST2(Constantes.GUARDAR_ENTRENADOR, json, 
                    Constantes.user.getUsername(), 
                    Constantes.user.getPassword()); 
        } 
 
        @Override 
        protected void onPostExecute(String response) { 
            activity.markAsDone(); 
            if (response.equals("")) { 
                // Refresh the list view then show success 
                Toast.makeText(getApplicationContext(), 
                        getString(R.string.successEntre), Toast.LENGTH_SHORT) 
                        .show(); 
            } else 
                Toast.makeText(getApplicationContext(), 
                        getString(R.string.err_unexp), Toast.LENGTH_LONG) 
                        .show(); 
        } 
    } 

请您参考如下方法:

我找到了解决方案!
我需要做的就是使用Grails用户 token ，并将其添加到 header 中，如下所示:

connection.setRequestProperty("Authorization", "Bearer " + Constantes.user.getToken()); // where get token returns the auth token
