Re: [Geoserver-users] Create Directory of Shape files Datastore with REST API JSON
I've been dealing with this situation for a couple of days now and here's
what I found
First, your original question includes an example that WORKS if you POST it
to
/rest/workspaces/topp/datastores.json
with a header setting Content-type: application/json. It will create a
datastore of the type Shapefile even if your url parameters point to a
directory that holds a shapefile. (/I thought I should mention this because
the web interface only lets you create a Shapefile datastore if you point
'url' to an specific shapefile and won let you pick just a directory/).
Your example doesn't work if you POST it to
/rest/workspaces/myWorkspace/datastores/name because that's not the REST
endpoint for creating datastores.
This is the minimum object you should POST if you specifically want to
create a data store of the type Directory of spatial files (shapefiles)
instead of Shapefile datastore.
dataStore: {
name: name,
type: Directory of spatial files (shapefiles),
connectionParameters: {
url: file:data/shapefiles,
fstype: shape
}
}
What Andreas said is true.

REST API tells you something like
connectionParameters:{
entry:[
{@key:memory mapped buffer,$:false},
{@key:fstype,$:shape}
]
}
it means that what you have to POST for a new datastore is:
connectionParameters:{
memory mapped buffer:false,
fstype:shape
}
I think this is due to Geoserver or the REST module using a specific library
to convert to JSON objects that behaves in that way when serializing a JAVA
object

Re: [Geoserver-users] Create Directory of Shape files Datastore with REST API JSON
Andrea,
Thanks for the reply, you are usually very helpful with my queries to the
geoserver lists, but really that is not a very constructive reply today.
I have already tried many things before posting to the list and I looked at the
REST API in detail. It is not clear exactly how the description of the
datastore maps to the information to create it. Perhaps you have not looked
either, as existing shape file directories are described as below, but that
leaves much to be desired in understanding how to create. Please see the
comments after.
{
dataStore:{
name:myStore,
type:Directory of spatial files (shapefiles),
enabled:true,
workspace:{
name:myWs,
href:http:\/\/gis.mysite.com\/rest\/workspaces\/myws.json
},
connectionParameters:{
entry:[
{@key:memory mapped buffer,$:false},
{@key:timezone,$:Europe\/London},
{@key:fstype,$:shape},
{@key:create spatial index,$:true},
{@key:charset,$:ISO-8859-1},
{@key:filetype,$:shapefile},
{@key:cache and reuse memory
maps,$:false},
{@key:enable spatial index,$:true},
{@key:url,$:file:gisdata\/myData},
{@key:namespace,$:wheatstone}
]
},
_default:false,
featureTypes:http:\/\/gis.seaplanner.com\/rest\/workspaces\/myws\/datastores\/mystore\/featuretypes.json
}
}
For a start, name and workspace are specified in the POST url, so I guess those
are optional?
The href attributes as well, seem unnecessary for a create, so I guess these
should not be needed?
Posting type as Directory of spatial files (shapefiles) would also seem a bit
odd, is that really the way?
As far as connection parameters, are they really specified in this convoluted
format? And will it use defaults not set?
Same with “_default” why underscore? And is it Optional, default false?
featureTypes again, this is like the href attributes, seems inappropriate for a
create/post, presumably excluded.
So really, what I am still asking is as before, what should be the right data
structure?
The curl example, only seems to describe creation with name and workspace,
putting the file path in the body:
curl -v -u admin:geoserver -XPUT -H Content-type: text/plain
-d file:///data/shapefiles/
http://localhost:8080/geoserver/rest/workspaces/acme/datastores/shapefiles/external.shp?configure=all;
If I want a name, description it is not clear.

Re: [Geoserver-users] Create Directory of Shape files Datastore with REST API JSON
As you suggest, I was already checking the source code for this. From what I can tell, there’s no direct way to create a datasource like this from the body of a JSON request. Perhaps I am wrong, but it will take the author of the code to tell us how as it is quite a convoluted process to understand. For now the simplest way is make a PUT request as per: PUT: http://localhost:8080/rest/workspaces/WORKSPACENAME/datastores/DATASTORENAME/external.shp In this url, you have 2 parameters: First: external: refers to a file external to geoserver on your sever. url: Get the content from the url specified in the body of the put. file: directly upload a file in the body of your put. Second: shp: Shapefile format properties: java properties file h2: h2 database spatialite: spatialite database The body of your put will either be a string to the location of your files, e.g. file://var/lib/gisdata/file:///\\var\lib\gisdata\ (this refers to a directory, though you can point to a single shape file) or http://data.geoserver.com/shapes.shp Alternatively if you use the file option, you put your file in the post and it’s saved on the sever. Hopefully that will help a few people! Interestingly, there’s a start at a GeoServer javascript client API in github based on openlayers: https://github.com/geoserver/geoserver/tree/master/src/restconfig/src/client/javascript Checked in by aaime on 18 Jun 2011… Regards, Mark From: andrea.a...@gmail.com [mailto:andrea.a...@gmail.com] On Behalf Of Andrea Aime Sent: 06 June 2014 14:17 Thanks for the reply, you are usually very helpful with my queries to the geoserver lists, but really that is not a very constructive reply today.
