在开发环境中正常工作时，产品上的音频无法正常工作（Angular 7）。
产品配置（VPS）：
AudioService：
export class AudioService {
audio = new Audio();
constructor() { }
isPlaying() {
return this.audio.currentTime > 0 && !this.audio.paused && !this.audio.ended && this.audio.readyState > 2;
}
play(name: string): void {
this.audio.src = `assets/audio/${name}`;
this.audio.crossOrigin = 'anonymous';
this.audio.load();
if (!this.isPlaying()) {
this.audio.play();
}
}
pause(): void {
if (this.isPlaying()) {
this.audio.pause();
}
}
}
CORS在Node.js端启用（使用Nestjs）。 main.ts：
app.enableCors();
Chrome日志：
未捕获（承诺）的DOMException：无法加载，因为没有找到了受支持的源。
Firefox日志：
NotSupportedError：src属性指示的媒体资源或分配的媒体提供者对象不合适。
查看网络控制台，我们可以看到带有：的myaudio.wav：
状态码：206部分内容
注意：加载图像效果很好！
编辑：
Nginx配置/ etc / nginx / sites-available / mywebsite：
# Redirection
server {
# if ($host = mywebsite.com) {
# return 301 https://$host$request_uri;
# } # managed by Certbot
listen 80;
listen [::]:80;
server_name mywebsite.com www.mywebsite.com;
return 301 https://$host$request_uri;
#return 404; # managed by Certbot
}
# Config
server {
server_name mywebsite.com www.mywebsite.com;
root /home/foo/mywebsite/gui;

}
if ($host = 'www.mywebsite.com') {
return 301 https://mywebsite.com$request_uri;
}
listen [::]:443 ssl ipv6only=on; # managed by Certbot

ssl_certificate_key /etc/letsencrypt/live/mywebsite.com/privkey.pem; # managed by Certbot
}
在开发环境localhost：4200 / assets / audio / myaudio.wav上运行正常
在生产环境https://mywebsite.com/assets/audio/myaudio.wav→返回主页上
虽然https://mywebsite.com/assets/image.jpg→正常工作
仅音频不起作用。
