最新排序的微信分享后端界面的一般过程(2)

根据access_token获取jsapiTicket

    /**
     * 微信分享，获取jsapiTicket
     */
    public String getShareJsapiTicket(String[] wxInfo) throws Exception {
        String access_Token = this.getWeiXinAccessToken(wxInfo);
        if (StringUtils.isEmpty(access_Token)) { // 获取 accessToken 失败
            //this.logger.warn(siteId + " accessToken is empty.");
            JsonObject jsonObject = new JsonObject();
            jsonObject.addProperty("errcode", "10000");
            jsonObject.addProperty("errmsg", "access_error");
            return jsonObject.toString();
        }
        String url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=" + access_Token + "&type=jsapi";
        String jsapiTicket = this.httpReqExecute(url);
        this.logger.warn(" from weixin api jsapiTicket is: " + jsapiTicket);
        if (StringUtils.isNotEmpty(jsapiTicket)) {
            return jsapiTicket;
        }
        return null;
    }

Http远程呼叫

    private String httpReqExecute(String url) {
        String result = "";
        DefaultHttpClient httpclient = null;
        try {
            httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(url);
            // 执行
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            if (entity != null && response.getStatusLine().getStatusCode() == 200) {
                result = EntityUtils.toString(entity, "UTF-8");
            }
        } catch (Exception e) {
            logger.error(" WeiXinShareAction 调用微信 API 失败！", e);
        } finally {// 关闭连接，释放资源
            httpclient.getConnectionManager().shutdown();
        }
        return result;
    }

返回成功
