Ubuntu下用geoserver-restconfig创建Coverage Store报错500，求解决

环境信息 #

• 操作系统：Ubuntu 22.04.2 LTS
• Python版本：3.10.6
• 使用工具包：geoserver-restconfig

代码示例 #

from geoserver.catalog import Catalog
cat = Catalog(service_url='http://localhost:8080/geoserver/rest',
              username='FAKE_USERNAME',
              password='FAKE_PASSWORD')

# 创建工作区
cat.create_workspace(name='demo', uri='http://demo')

# 创建Coverage Store
path = 'indicators/coolingdd/rcp_2_6/ensemble/coolingdd_rcp26_multi-model-mean_-_-_20210101-20301230.tiff'
cat.create_coveragestore(name='NAME',
                         workspace='demo',
                         path=path,
                         type='GeoTIFF',
                         create_layer=True,
                         layer_name='TITLE',
                         upload_data=False)

说明：indicators目录与Python脚本在同一运行目录下

报错信息 #

Traceback (most recent call last):

    cat.create_coveragestore(name='NAME',

排查过程 #

更新1 #

已将GeoServer全局设置中的日志级别改为developer，但仍出现相同错误。

更新2 #

查看GeoServer日志文件，发现核心错误：

06 Mar 11:25:48 WARN   [gce.geotiff] - File /var/lib/tomcat9/webapps/geoserver/data/indicators/coolingdd/rcp_2_6/ensemble/coolingdd_rcp26_multi-model-mean_-_-_20210101-20301230.tiff does not exist.
org.geotools.data.DataSourceException: File /var/lib/tomcat9/webapps/geoserver/data/indicators/coolingdd/rcp_2_6/ensemble/coolingdd_rcp26_multi-model-mean_-_-_20210101-20301230.tiff does not exist.

结论 #

原本误以为create_coveragestore函数会自动将本地TIFF文件上传至GeoServer，但从日志可以看出，该函数会直接到GeoServer的数据目录（/var/lib/tomcat9/webapps/geoserver/data/）查找指定路径的文件。因此正确流程是：先将TIFF文件上传到GeoServer数据目录的对应路径下，再调用create_coveragestore并填写数据目录下的相对路径。
