LiveQing二次开发接口对接说明示列

LiveQing云端流媒体服务软件，支持视频视频转码、RTMP推流直播、RTMP/HLS/HTTP-FLV直播分发、服务端录像、录像检索、时移回放；支持与LiveGBS对接，即将支持内网数据穿透及远程服务配置。

一、 快速安装

1. 下载地址
2. 下载对应环境的安装包
3. 解压安装包
4. Windows下双击EasyDSS.exe直接启动
5. Linux下解压目录执行./start.sh

注：路径中不能包含中文

二、 二次开发

二次开发中，方式是在自己业务系统后端登录接口中，调用流媒体的登录接口，获取所需的sid或是token

1. 封闭内网使用

在业务使用，如果只是使用EasyDSS提供视频分发能力，且不会对外公开接口端口10080(默认端口)，可以直接将接口鉴权关闭，具体服务器登录 http://localhost:10080 默认用户名/密码 admin/admin, 在 基础配置 页面，【接口鉴权】开关。

接口鉴权

2. 业务系统对接

2.1 cookie方式

注： HttpOnly = true 客户端API（例如JavaScript）无法访问仅限http的cookie。 此限制通过跨站点脚本（XSS）消除了cookie被盗的威胁。

1. 在后端业务代码中对接，如Java/PHP/Node.js 等
2. 调用EasyDSS登录接口，接口调用成功后会在请求Headers的cookie中写入sid
3. 取出cookie里的sid
4. 其它接口调用时在请求头cookies中传递sid
5. Content-Type:application/x-www-form-urlencoded
6. 接口请求路径示例：http://localhost:10080/login

代码示例：Java

2.1.1 获取sid

import java.io.DataOutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Set;

public class GetLoginSid {
 public static void main(String[] args) throws Exception {
        URL url = new URL("http://demo.easydss.com:10080/login");
        
        //发起POST请求，并传递username，password参数（需要md5加密）
        HttpURLConnection conn = (HttpURLConnection)url.openConnection();
        conn.setDoOutput(true);
        conn.setDoInput(true);
        conn.setRequestMethod("POST");      
        conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded"); 
        DataOutputStream out = new DataOutputStream(conn.getOutputStream());  
        String content = "username=admin&password=21232f297a57a5a743894a0e4a801fc3";
        out.writeBytes(content); 
        out.flush();  
        out.close();
        
        
        Map> headerFields = conn.getHeaderFields();
        
        Set headerFieldsSet = headerFields.keySet();
        
        Iterator hearerFieldsIter = headerFieldsSet.iterator();

        while (hearerFieldsIter.hasNext()) {

            String headerFieldKey = hearerFieldsIter.next();

            if ("Set-Cookie".equalsIgnoreCase(headerFieldKey)) {

                List headerFieldValue = headerFields.get(headerFieldKey);

                for (String headerValue : headerFieldValue) {                       
                    String[] fields = headerValue.split(";\\s*");
                    for (int j = 0; j < fields.length; j++) {
                        if (fields[j].indexOf('=') > 0) {
                            String[] f = fields[j].split("=");
                            if ("Expires".equalsIgnoreCase(f[0])) {                        
                                 System.out.println("Expires:" + f[1]);
                            }
                            else if ("Max-Age".equalsIgnoreCase(f[0])) {                   
                                 System.out.println("Max-Age:" + f[1]);
                            }else if ("sid".equalsIgnoreCase(f[0])) {   //获取sid     
                                 System.out.println("sid:" + f[1]);
                            }
                        }
                    }
                }
           }
        }
    }
   }
