防火墙配置¶
If a project contains online layers (PostGIS, WMS, WFS, etc), QFieldCloud will try to establish a connection to these services. Sometimes these services are behind a firewall and the system administrators need to allowlist the QFieldCloud IP.
The hosted version on app.qfield.cloud will connect from the following ip addresses:
| 服务 | IP |
|---|---|
| app.qfield.cloud | 159.100.252.133 |
| app.qfield.cloud | 194.182.188.113 |
PostgreSQL配置¶
如果您的工程包含PostgreSQL (PostGIS) 图层，则需要配置PostgreSQL服务器，便于允许从 app.qfield.cloud IP 地址进行连接。
否则，将出现如下错误：
FATAL: no pg_hba.conf entry for host "185.203.114.168", user "qfc", database "mydb_test", SSL off
WARNING:QGIS_MSGLOG:1 unavailable layer(s) found:
To do so, you need to edit the pg_hba.conf file where your PostgreSQL server is hosted. For more information, refer to recommendations on StackOverflow questions.
