Hello,
I want to publish a polyline shapefile to geoserver.
Sometimes it works, sometimes it does not. I do not understand why.
Here is my code to publish:
from geoserver.catalog import Catalog
def save_geoserver(data):
geoserver_uri = 'http://localhost:8080/geoserver'
from geoserver.workspace import ResourceInfo
cat = Catalog("http://localhost:8080/geoserver/rest";, username='admin',
password='geoserver')
wks_name = 'newWorkspaceName'
uri = geoserver_uri +"/"+ wks_name
store_name = 'newStore'
data = data
def check_workspace(workspace_name):
print("test for workspace")
check_workspace = False #create a variable to test if workspace
exists already
if(cat.get_workspaces(workspace_name)):
print("found workspace")
check_workspace = True #set the variable to true, if workspace
exists
return check_workspace
#check_workspace(wks_name)
check_store = False
# def create_data(store_name, data, data_name, wks_name):
# cat.create_featurestore(store_name, data, workspace=wks_name)
# cat.add_data_to_store(store=store_name, name=data_name,
data=data, workspace=wks_name)
# print(store_name.workspace)
if check_workspace(wks_name): # if workspace exists, create the
featurestore
# print("Workspace exists")
if(cat.get_store(store_name, workspace=wks_name)):
cat.add_data_to_store(store=store_name, name=store_name,
data=data, workspace=wks_name)
print("Store found. Data has been written.")
else:
print("Store does not exist. Store has been created. Data has
been written to the store.")
cat.create_featurestore(store_name, data, wks_name)
#create_data(store_name, data, "Test name", wks_name)
cat.add_data_to_store(store=store_name, name=store_name,
data=data, workspace=wks_name)
else: #if workspace does not exists, create the workspace and the
featurestore
cat.create_workspace(wks_name, uri)
#create_data(store_name, data, "Test name", wks_name)
cat.add_data_to_store(store=store_name, name=store_name, data=data,
workspace=wks_name)
print("Workspace does not exist. Workspace and store have been
created. Data has been written to the store.")
# try:
# cat.publish_featuretype(data, cat.get_store(store_name,
wks_name),"GCS_WGS_1984")
# except Exception as e:
# print("Error: ", e)
save_geoserver(r'C:\Users\this-pc\Documents\Navoi\Navoi.zip')
I can see the files saved in geoserver, however I cannot access them via
WMS, in JOSM.
I can see one of the files via WMS in JOSM, so I was able to do it. Perhaps
I may have made a change, but now it does not work.
The zip file contains the shp, .prj, .cpg, .dbf, .qpj, .shx files.
I was able to publish it previously, when also I was using a geojson, that
I imported to QGIS, saved as shapefile, then created an archive.
One of the reason I think it does not work is that i made a script to
create the shapefile from a json file automatically and save it to a zip
file, without making the steps manually in QGIS. I used the pyshp library.
You can see the code below.
def write_shp(input, output):
geometries = []
with shapefile.Writer(output) as w:
w.field('FID', 'C')
for i in input['features']:
try:
geometries.append(i['geometry']['coordinates'])
#print("geometry: ", i['geometry']['coordinates'])
except Exception as error:
print("Error appending line to geometries list: ", error)
#print(len(geometries))
try:
for i in geometries:
w.line(geometries)
w.record(geometries.index(i)+1)
except Exception as error:
print("Error adding lines: ", error )
w.close()
def createPrjFile(shpFile):
try:
prjFile = open(shpFile + '.prj', 'w')
prjStr = 'GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS
84",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]]'
prjFile.write(prjStr)
prjFile.close()
cpgFile = open(shpFile + '.cpg', 'w')
cpgStr = 'UTF-8'
cpgFile.write(cpgStr)
cpgFile.close()
qpjFile = open(shpFile + '.qpj', 'w')
qpjStr = 'GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS
84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4326"]]'
qpjFile.write(qpjStr)
qpjFile.close()
print("Additional files written succesfully.")
except Exception as error:
print("Error creating additional files: ", error)
def createZipFile(path):
zip_name = str(path.rsplit('\\', 1)[1])
print(zip_name)
files_list = []
for i in ['.dbf','.prj','.shx','.shp','.cpg','.qpj']:
files_list.append(zip_name+str(i))
#print(files_list)
try:
print("Creating a zip archive from shapefile and .dbf, .prj, .shx
files")
zipObj = ZipFile(path+'.zip', 'w')
for item in files_list:
zipObj.write(path.rsplit('\\', 1)[0]+'\\' + item, arcname =
item)
print("Shapefile has been archived to: ", path.strip() + ".zip")
zipObj.close()
except Exception as error:
print("Error saving to zip file: ", error)
Any help would be great.
