大华视频监控对接

几种不同方案的兼容性表：

推荐使用：WSPlayer无插件播放器

wsplayer播放器demo下载地址：

 下载压缩包里面有一个对接文档，按对接文档的说明，因为跨域的问题，因此需要弄后台接口代理代理大华接口服务。

 下面是API文档的网页地址：

https://open-icc.dahuatech.com/#/home?url=%3Fnav%3Dwiki%2Fevo-oauth%2FuserPass.html&version=enterprisebase/5.0.16&blank=true

 关于后台接口的转发代理，不用自己写，大华给了java示例代码(c++的也有)，可以直接调用：

https://open-icc.dahuatech.com/#/home?url=%3Fnav%3Dwiki%2Fcommon%2Fquickstart.html%23%E9%89%B4%E6%9D%83%E8%AE%A4%E8%AF%81&version=enterprisebase/5.0.16&blank=true

将示例java代码移植到项目后台中去，然后配置大华平台服务的ip、端口、key等信息即可。

 只有调用部分是自己写的，代码如下：

总结一下和海康平台的区别：

海康：需要插件、不需要后台服务代理

大华：不需要插件，需要后台服务代理
