Geoserver

geoserver Is a Go Package For Manipulating a GeoServer Instance via the GeoServer REST API.


How to install:

  • go get -v gopkg.in/hishamkaram/geoserver.v1
    • now you can import the package from gopkg.in/hishamkaram/geoserver.v1, example:
      import (
        ...
        "gopkg.in/hishamkaram/geoserver.v1"
        ...
      )
      

usage:

  • Create new Catalog (which contains all available operations):
    • gsCatalog := geoserver.GetCatalog("http://localhost:8080/geoserver13/", "admin", "geoserver")
  • Use catalog Methods to Perform a Geoserver REST Operation:
    • Create New workspace:
      created, err := gsCatalog.CreateWorkspace("golang")
      if err != nil {
        fmt.Printf("\nError:%s\n", err)
      }
      fmt.Println(strconv.FormatBool(created))
      

      output if created:

      true
      

      output if error:

  • Get Layers through GetLayers take workspace as paramter if empty workspace will be ignored and geoserver will return all public layers
    layers, err := gsCatalog.GetLayers("")
    if err != nil {
      fmt.Printf("\nError:%s\n", err)
    }
    for _, lyr := range layers {
      fmt.Printf("\nName:%s  href:%s\n", lyr.Name, lyr.Href)
    }
    

    output:

    INFO[31-03-2018 19:04:44] url:http://localhost:8080/geoserver13/rest/layers	response Status=200

    ......
    
  • Get Specific Layer from Geoserver:
    layer, err := gsCatalog.GetLayer("nurc", "Arc_Sample")
    if err != nil {
      fmt.Printf("\nError:%s\n", err)
    } else {
      fmt.Printf("%+v\n", layer)
    }
    

    output:
