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
- 下载地址
- 下载对应环境的安装包
- 解压安装包
- Windows下双击LiveQing.exe直接启动
- 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LiveQing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。
- 在后端业务代码中对接,如Java/PHP/Node.js 等
- 调用LiveQing登录接口,接口调用成功后会在请求Headers的cookie中写入sid
- 取出cookie里的sid
- 其它接口调用时在请求头cookies中传递sid
- Content-Type:application/x-www-form-urlencoded
- 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://cloud.liveqing.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<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]);
}
}
}
}
}
}
}
}
运行如下

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://cloud.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");
//这里传递上一步获得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());
}
}
运行如下
2.2 token方式
- 调用登录接口获取token
- 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());
}
}

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";

sbf.append(strRead);
sbf.append("\r\n");
}
reader.close();
System.out.println(sbf.toString());
}
}
