私有点播cdn切换前-测试总结

1，前cdn域名和后cdn域名列表

video.xx.com（前） xx.qiniu.cloudcdn.net（后）    audio.xx.com（钱） xx.qiniu.cloudcdn.net（后）

2，切换要测试条目

1.m3u8 不缓存；2.回源鉴权，返回缓存；3.过期、不争取token报 401

3，测试ping到的节点。方便加host来测试

liuhanlindemac:private yishiyaonie$ ping fcdbig.qiniu.cloudcdn.netPING c01.i07.ctlshqn2.lv3.cloudglb.com (122.228.193.89): 56 data bytes64 bytes from 122.228.193.89: icmp_seq=0 ttl=51 time=13.811 ms64 bytes from 122.228.193.89: icmp_seq=1 ttl=51 time=13.814 ms

可以看到ping到的节点是：122.228.193.89

4，首先测试m3u8不缓存。

这个测试起来简单。因为私有资源，每次签名时间变了。m3u8里面的链接也就改变了。相当于m3u8的内容改变了，看下是否是同一个etag就能验证。

生成一条下载链接测试：

liuhanlindemac:private yishiyaonie$ curl -I "http://122.228.193.89/141a1c9c213378e6310c23cc74acc918.m3u8?pm3u8/0/expires/14400&e=1442911336&token=TZyT059uJpbvYeklLS-WaJ4poi4SYia8_lm-nKV8:f-3MNFwe3t1SDVmyrA8dVNzh74Y=" -H "Host:audio.gaiavoicelight.com"HTTP/1.1 200 OKDate: Tue, 22 Sep 2015 07:45:59 GMTContent-Length: 32700Accept-Ranges: bytesContent-Type: application/x-mpegurlCache-Control: public, max-age=31536000Connection: Keep-AliveEtag: "ALjdCt13QvQ6zMWYZsvLtev_N2Ax"X-Private: 1Server: nginx/1.4.4Access-Control-Allow-Origin: *Access-Control-Max-Age: 2592000Content-Transfer-Encoding: binaryX-Log: mc.g;FOPAGENT;pm3u8.rsrc:2;pm3u8.rewrite:2;FFMPEG:5;FOPAGENT:7;FOPAGENT;pm3u8.rsrc:2;pm3u8.rewrite:2;FFMPEG:5;FOPAGENT:7;FOPG:8;FOPAGENT;IO:12X-Reqid: ghIAAM-hBO8kPQYUX-Qiniu-Zone: 0Fw-Via: Configured MISS from 122.228.193.86

可以看到：

Content-Length: 32700Etag: "ALjdCt13QvQ6zMWYZsvLtev_N2Ax"Fw-Via: Configured MISS from 122.228.193.86

然后我再生成一个链接

liuhanlindemac:private yishiyaonie$ curl -I "http://122.228.193.89/141a1c9c213378e6310c23cc74acc918.m3u8?pm3u8/0/expires/144000&e=1442911781&token=TZyT059uJpbvYeklLS-WaJ4poi4SYia8_lm-nKV8:_TJwf_xC11A0xjcKMk6ARg-s0Vc="  -H "Host:audio.gaiavoicelight.com"HTTP/1.1 200 OKDate: Tue, 22 Sep 2015 07:50:44 GMTContent-Length: 32700Accept-Ranges: bytesContent-Type: application/x-mpegurlCache-Control: public, max-age=31536000Connection: Keep-AliveEtag: "AICzgiNIVSTXEyuLwnDch4GNwqRI"X-Private: 1Server: nginx/1.4.4Access-Control-Allow-Origin: *Access-Control-Max-Age: 2592000Content-Transfer-Encoding: binaryX-Log: mc.g;FOPAGENT;pm3u8.rsrc:2;pm3u8.rewrite;FFMPEG:3;FOPAGENT:4;FOPAGENT;pm3u8.rsrc:2;pm3u8.rewrite;FFMPEG:3;FOPAGENT:4;FOPG:6;FOPAGENT;IO:9X-Reqid: Ul4AAPIDek1nPQYUX-Qiniu-Zone: 0Fw-Via: Configured MISS from 122.228.193.86

可以看到

Content-Length: 32700Etag: "AICzgiNIVSTXEyuLwnDch4GNwqRI"Fw-Via: Configured MISS from 122.228.193.86

所以确定m3u8不缓存。测试成功。

5，测试ts文件缓存（同样也是查etag）

结合上面测试方法中生成的两个url，分别curl下。找最后的ts文件测试，因为ts没变，链接的访问参数变了。所以应该是去问号缓存的。我们来看下etag。

liuhanlindemac:private yishiyaonie$ curl -I "http://122.228.193.89/UZMp6xzpSs1ftjq7tmK4HM8QT8Q=/ltfpFeYczqxynp3GasM3D_JWyZL-/000152.ts?e=1443052398&token=TZyT059uJpbvYeklLS-WaJ4poi4SYia8_lm-nKV8:86oim5GsmrBMI9XTGTGv5Teov40" -H "Host:7xigxg.com2.z0.glb.qiniucdn.com"HTTP/1.1 200 OKDate: Tue, 22 Sep 2015 07:57:33 GMTContent-Length: 10340Accept-Ranges: bytesContent-Type: video/mp2tLast-Modified: Mon, 25 May 2015 19:22:10 GMTCache-Control: public, max-age=31536000Connection: Keep-AliveEtag: "FklSMcFEocIO5iMHfdWsHbZU3o29"X-Private: 1Server: nginx/1.4.4Access-Control-Allow-Origin: *Access-Control-Max-Age: 2592000Content-Transfer-Encoding: binaryX-Log: mc.g;IO:1X-Reqid: EGoAAAxkcn7GPQYUX-Qiniu-Zone: 0Content-Disposition: inline; filename="000152.ts"Fw-Via: Configured MISS from 122.228.193.85, Configured MISS from 122.228.193.86

Etag: “FklSMcFEocIO5iMHfdWsHbZU3o29”

另外一个url：

liuhanlindemac:private yishiyaonie$ curl -I  "http://122.228.193.89/UZMp6xzpSs1ftjq7tmK4HM8QT8Q=/ltfpFeYczqxynp3GasM3D_JWyZL-/000152.ts?e=1442923164&token=TZyT059uJpbvYeklLS-WaJ4poi4SYia8_lm-nKV8:CCmrP8bFDt7Y3IFKJGLtkar6Gs0" -H "Host:7xigxg.com2.z0.glb.qiniucdn.com"HTTP/1.1 304 Not ModifiedDate: Tue, 22 Sep 2015 08:03:10 GMTConnection: CloseFw-Via: DISK HIT NOT MODIFIED from 122.228.193.83, Configured MISS from 122.228.193.86

结果出现304，这个是失败的。因为请求304，需要发请求的时候，告诉服务端已经有本地缓存了。用本地的缓存。需要带一个请求头告诉服务端才可以。
