PHP¶

The examples in this section use the server-side scripting language PHP, a popular language for dynamic webpages. PHP has cURL functions , as well as XML functions, making it a convenient method for performing batch processing through the Geoserver REST interface. The following scripts execute single requests, but can be easily modified with looping structures to perform batch processing.

POST with PHP/cURL¶

The following script attempts to add a new workspace.

<?php
    // Open log file
    $logfh = fopen("GeoserverPHP.log", 'w') or die("can't open log file");

    // Initiate cURL session
    $service = "http://localhost:8080/geoserver/"; // replace with your URL
    $request = "rest/workspaces"; // to add a new workspace
    $url = $service . $request;
    $ch = curl_init($url);

    // Optional settings for debugging
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //option to return string
    curl_setopt($ch, CURLOPT_VERBOSE, true);
    curl_setopt($ch, CURLOPT_STDERR, $logfh); // logs curl messages

    //Required POST request settings
    curl_setopt($ch, CURLOPT_POST, True);
    $passwordStr = "admin:geoserver"; // replace with your username:password
    curl_setopt($ch, CURLOPT_USERPWD, $passwordStr);

    //POST data
    curl_setopt($ch, CURLOPT_HTTPHEADER,
              array("Content-type: application/xml"));
    $xmlStr = "<workspace><name>test_ws</name></workspace>";
    curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlStr);

    //POST return code
    $successCode = 201;

    $buffer = curl_exec($ch); // Execute the curl request

    // Check for errors and process results
    $info = curl_getinfo($ch);
    if ($info['http_code'] != $successCode) {
      $msgStr = "# Unsuccessful cURL request to ";
      $msgStr .= $url." [". $info['http_code']. "]\n";
      fwrite($logfh, $msgStr);
    } else {
      $msgStr = "# Successful cURL request to ".$url."\n";
      fwrite($logfh, $msgStr);
    }
    fwrite($logfh, $buffer."\n");

    curl_close($ch); // free resources if curl handle will not be reused
    fclose($logfh);  // close logfile

?>

The logfile should look something like:

* About to connect() to www.example.com port 80 (#0)
*   Trying 123.456.78.90... * connected
* Connected to www.example.com (123.456.78.90) port 80 (#0)
* Server auth using Basic with user 'admin'
> POST /geoserver/rest/workspaces HTTP/1.1
Authorization: Basic sDsdfjkLDFOIedlsdkfj
Host: www.example.com
Accept: */*
Content-type: application/xml
Content-Length: 43

< HTTP/1.1 201 Created
< Date: Fri, 21 May 2010 15:44:47 GMT
< Server: Apache-Coyote/1.1
< Location: http://www.example.com/geoserver/rest/workspaces/test_ws
< Content-Length: 0
< Content-Type: text/plain
<
* Connection #0 to host www.example.com left intact
# Successful cURL request to http://www.example.com/geoserver/rest/workspaces

* Closing connection #0

If the cURL request fails, a code other than 201 will be returned. Here are some possible values:

Code	Meaning
0	Couldn’t resolve host; possibly a typo in host name
201	Successful POST
30x	Redirect; possibly a typo in the URL
401	Invalid username or password
405	Method not Allowed: check request syntax
500	Geoserver is unable to process the request, e.g. the workspace already exists, the xml is malformed, ...

For other codes see cURL Error Codes and HTTP Codes.

GET with PHP/cURL¶

The script above can be modified to perform a GET request to obtain the names of all workspaces by replacing the code blocks for required settings, data and return code with the following:

<?php
    // Required GET request settings
    // curl_setopt($ch, CURLOPT_GET, True); // CURLOPT_GET is True by default

    //GET data
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Accept: application/xml"));

    //GET return code
    $successCode = 200;
?>

The logfile should now include lines like:

> GET /geoserver/rest/workspaces HTTP/1.1

< HTTP/1.1 200 OK

DELETE with PHP/cURL¶

To delete the (empty) workspace we just created, the script is modified as follows:

<?php
    $request = "rest/workspaces/test_ws"; // to delete this workspace
?>

<?php
    //Required DELETE request settings
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
    $passwordStr = "admin:geoserver"; // replace with your username:password
    curl_setopt($ch, CURLOPT_USERPWD, $passwordStr);

    //DELETE data
    curl_setopt($ch, CURLOPT_HTTPHEADER,
              array("Content-type: application/atom+xml"));

    //DELETE return code
    $successCode = 200;
?>

The log file will include lines like:

> DELETE /geoserver/rest/workspaces/test_ws HTTP/1.1

< HTTP/1.1 200 OK
