获取Token接口

get方式

public String getToken() {
        try {
            // 获取token路径
            String tokenUrl = CodeRepositoryUtil.getSysConfigValue("identity.token");
            // 请求路径
            URIBuilder uriBuilder = new URIBuilder(tokenUrl);
            // 参数
            uriBuilder.addParameter("client_id", clientId);
            uriBuilder.addParameter("client_secret", clientSecret);
            // 创建一个连接
            CloseableHttpClient httpclient = HttpClients.createDefault();
            // get请求
            HttpGet get = new HttpGet(uriBuilder.build());
            // 执行请求
            CloseableHttpResponse Response = httpclient.execute(get);
            // 获取相应数据
            HttpEntity entity = Response.getEntity();
            // 转化字符
            String jsonStr = EntityUtils.toString(entity, "UTF-8");
            // 关闭请求
            Response.close();
            return JSONObject.parseObject(jsonStr).getString("accessToken");
        } catch (Exception e) {
            logger.error(e.getMessage());
        }

        return null;
    }

　　POST方式

public String getTokenNew() {
        // 获取token路径
        String tokenUrl ="";// CodeRepositoryUtil.getSysConfigValue("identity.token");
        try {
            // 请求路径
            Map<String,String> map = new HashMap<>();
            URIBuilder uriBuilder = new URIBuilder(tokenUrl);
            // 参数
            map.put("client_id", client_id);
            map.put("client_secret", client_secret);
            map.put("grant_type", grant_type);
            map.put("resource_provider_id", resource_provider_id);
            map.put("Content-Type", "application/json");
            HttpClient httpclient = new DefaultHttpClient();
            httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 15000);
            HttpPost httppost = new HttpPost(tokenUrl);
            httppost.addHeader("Content-type","application/json; charset=utf-8");

            StringEntity entity = new StringEntity(JSONObject.toJSONString(map).toString());
            httppost.setEntity(entity);
            HttpResponse resp = httpclient.execute(httppost);
            // 获取相应数据
            HttpEntity result = resp.getEntity();
            // 转化字符
            String jsonStr = EntityUtils.toString(result, "UTF-8");
            // 关闭请求
            httpclient.getConnectionManager().shutdown();;
            return JSONObject.parseObject(jsonStr).getString("access_token");
        } catch (Exception e) {
            logger.error(e.getMessage());
        }
        return null;
