LiveQing流媒体服务器软件，包含云平台服务，云直播服务等，支持与LiveGBS的对接，支持设备RTMP推流，视频文件转码等功能java

集成二次开发

二次开发中，方式是在本身业务系统后端登陆接口中，调用流媒体的登陆接口，获取所需的sid或是token后端

1. 封闭内网使用

在业务使用，提供视频分发能力时，且不会对外公开接口端口10080(默认端口)，能够直接将接口鉴权关闭，具体服务器登陆 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。服务器

2. 业务系统对接(两种方式)

2.1 cookie方式

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

在后端业务代码中对接，如Java/PHP/Node.js 等app
调用LiveDSS登陆接口，接口调用成功后会在请求Headers的cookie中写入sid加密
取出cookie里的sidurl
其它接口调用时在请求头cookies中传递sid.net
Content-Type:application/x-www-form-urlencoded3d
接口请求路径示例：http://localhost:10080/logincode

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://dss.liveqing.com:10080/login");
        //发起POST请求，并传递username，password参数（须要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<String, List<String>> headerFields = conn.getHeaderFields();
        Set<String> headerFieldsSet = headerFields.keySet();
        Iterator<String> hearerFieldsIter = headerFieldsSet.iterator();

        while (hearerFieldsIter.hasNext()) {
            String headerFieldKey = hearerFieldsIter.next();

            if ("Set-Cookie".equalsIgnoreCase(headerFieldKey)) {
                List<String> 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]);
                            }
                       }
                    }
                }
          }
        }
    }
  }

运行以下

2.1.2 携带sid调用其它接口

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class RequestOtherAPI {

public static void main(String[] args) throws Exception {
        URL url = new URL("http://dss.liveqing.com:10080/live/list");
        HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setDoOutput(true);
        conn.setDoInput(true);
        conn.setRequestMethod("POST");     
        conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
      //这里传递上一步得到sid
        conn.setRequestProperty("Cookie","sid=s%3Ark-TEuVtm.WnWoXuDY%2FldJuEc64I6TXjd0Fq1eqByEd4ng1UwNb2I;");
            DataOutputStream out = new DataOutputStream(conn.getOutputStream()); 
            String content = "start=0&limit=10";
            out.writeBytes(content);
            out.flush(); 
            out.close();
            conn.connect();
            StringBuffer sbf = new StringBuffer();
            InputStream is = conn.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            String strRead = null;
            while ((strRead = reader.readLine()) != null) {
                sbf.append(strRead);
                sbf.append("\r\n");
            }
            reader.close();
            System.out.println(sbf.toString());
    }
  }

运行以下

2.2 token方式

调用登陆接口获取token，调用时传递 onlytoken=true
如： http://dss.liveqing.com:10080/login?username=admin&password=21232f29757a5a&onlytoken=true
Content-Type:application/x-www-form-urlencoded
其它接口调用时传递附加token入参

代码示例：Java

2.2.1 获取token

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class GetLoginToken {

public static void main(String[] args) throws Exception {
        URL url = new URL("http://localhost:10080/login");
        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();
            conn.connect();
            StringBuffer sbf = new StringBuffer();
            InputStream is = conn.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            String strRead = null;
            while ((strRead = reader.readLine()) != null) {
                sbf.append(strRead);
                sbf.append("\r\n");
            }
            reader.close();
            System.out.println(sbf.toString());
    }
  }

运行以下

2.2.2 携带token调用其它接口

其余接口调用时，附加token入参

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class RequestOtherAPIByToken {
public static void main(String[] args) throws Exception {
        URL url = new URL("http://localhost:10080/live/list");
        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 = "start=0&limit=10&token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1Mzc3NzExNTAsInB3IjoiMjEyMzJmMjk3YTU3YTVhNzQzODk0YTBlNGE4MDFmYzMiLCJ0bSI6MTUzNzY4NDc1MCwidW4iOiJhZG1pbiJ9.b1U-R-_HVKV9reWRD50327B1ztUqs3gowUGi_lDzlmU";
            out.writeBytes(content);
            out.flush(); 
            out.close();
            conn.connect();
            StringBuffer sbf = new StringBuffer();
            InputStream is = conn.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            String strRead = null;
            while ((strRead = reader.readLine()) != null) {
                sbf.append(strRead);
               sbf.append("\r\n");
            }
            reader.close();
            System.out.println(sbf.toString());
    }
}
