调研方向
从 lib/SystemStatistics.php 中 workaround 所引用的 getAppsInfo() 调用开始，然后跟踪 /apps/serverinfo/update 请求以及针对 https://apps.nextcloud.com/api/v1/apps.json 的 appstoreFetcher 日志条目。在监控与 apps.nextcloud.com 的连通性的同时复现该请求。完成标准是：打开 serverinfo 不再导致 appstore 连接被阻止或受到影响。
由索引模型根据 Issue 内容生成。
描述
I reported this already in the appstore issue-tracker: https://github.com/nextcloud/appstore/issues/1137
I'm posting this here, because I observed this behavior only when the AppstoreFetcher is called by serverinfo.
Steps to reproduce
- make sure apps.nextcloud.com is accessible:
serverprompt:~# echo -e "\nResponse-Code: $(curl -Lo /dev/null -w "%{http_code}" apps.nextcloud.com)\n==================\n"
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 320 100 320 0 0 8396 0 --:--:-- --:--:-- --:--:-- 8421
100 301k 100 301k 0 0 271k 0 0:00:01 0:00:01 --:--:-- 319k
Response-Code: 200
==================
- tail -f your logfile:
tail -F $(nextcloud logfile) | jqand keep it open - open serverinfo in a browser tab
- whait for log message as below.
- close serverinfo tab, since the message repeates every 5 minutes.
- recheck accessibility as under 1:
serverprompt:~# echo -e "\nResponse-Code: $(curl -Lo /dev/null -w "%{http_code}" apps.nextcloud.com)\n==================\n"
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0
curl: (7) Failed to connect to apps.nextcloud.com port 80 after 22 ms: Connection refused
Response-Code: 000
==================
Expected behaviour
no impairments in the connection to apps.nextcloud.com
Actual behaviour
The affected IP get banned/blocked by apps.nextcloud.com.
Since it is my home network, I can easily fetch a new IP but every time a serverinfo tab is opened (no matter what instance, even newly setup in a virtual machine) it get banned again.
Because in my case it's the WAN Ip of my home network, i can not reach the appstore in my browser eather.

coment this line: https://github.com/nextcloud/serverinfo/blob/544bacf952cc94ea0d6ec1a828e1de4971acbb94/lib/SystemStatistics.php#L74
// 'apps' => $this->getAppsInfo()
