【问题描述】：

我的原始流名称是7a0938b1a5e64c5597f959610cb219c9。我想在调用on_publish之后将我的流名称更改为testchannel1。但是在hls_path中，流名称仍然与以前相同。如何将我的配置文件更改为实现它。

nginx配置文件

application myapp 
    on_publish http://192.168.50.98:8080/auth/on_publish;
    on_publish_done http://192.168.50.98:8080/auth/live/on_connect;

    live on;
    hls on;
    hls_path /usr/share/nginx/html/live;
    hls_nested on;
    hls_fragment 2s;
    hls_playlist_length 6s;
    hls_fragment_naming system;

【参考方案1】：

解决方案

Nginx-RTMP 模块支持使用通常的 HTTP 重定向 301 或 302（永久或临时）的 on_publish 回调 URL 将流重定向到另一个。 （请注意，它仅适用于对 rtmp 服务器的请求，而不适用于 hls，因为它是由 http 服务器处理的）

例如在一个简单的烧瓶应用中

from flask import Flask, redirect
app = Flask('Hello')  

@app.route('/publish-check')
def publish_check():
    return redirect('rtmp://127.0.0.1/hls-live/testchannel1', code=302)

新的 HTTP 响应标头

HTTP/1.1 302
Location: rtmp://127.0.0.1/hls-live/testchannel1

新的nginx配置文件

application myapp 
    on_publish http://vm1.mysite.com/auth/on_publish;
    on_publish_done http://vm1.mysite.com/auth/live/on_connect;

    live on;
#   hls on;
#   hls_path /usr/share/nginx/html/live;
#   hls_nested on;
#   hls_fragment 2s;
#   hls_playlist_length 6s;
#   hls_fragment_naming system;
   
application hls-live 
    #on_publish http://vm1.chenshenglong.com;

    live on;
    hls on;
    hls_path /usr/share/nginx/html/live;
    hls_nested on;
    hls_fragment 2s;
    hls_playlist_length 6s;
    hls_fragment_naming system;
