Sending file to Solr via HTTP POST

[Caroline Tan <ca...@gmail.com>]

Hi,
>From the Solr wiki on ExtractingRequestHandler tutorial, when it comes to
the part to post file to Solr, it always uses the curl command, e.g.
curl 'http://localhost:8983/*solr*/update/extract?literal.id=doc1&commit=true'
-F myfile=@tutorial.html

I have never used curl and i was thinking is  there any replacement to such
method?

Is there any API that i can use to achieve the same thing in a java
project without relying on CURL? Does SolrJ have such method? Thanks

Here is a brief example of how to use SolrJ with the
ExtractingRequestHandler:

          ContentStreamUpdateRequest req = new
ContentStreamUpdateRequest("/update/extract");
          req.addFile(fileToIndex);
          req.setParam("literal.id", getId(fileToIndex));
          req.setParam("literal.hostname", getHostname());
          req.setParam("literal.filename", fileToIndex.getName());

          try {
            getSolrServer().request(req);
          } catch (SolrServerException e) {
            e.printStackTrace();
          }

You'll need a request handler configured in solrconfig.xml:

  <!-- Solr Cell Wiki: http://wiki.apache.org/solr/ExtractingRequestHandler-->
  <requestHandler name="/update/extract"
class="org.apache.solr.handler.extraction.ExtractingRequestHandler"
startup="lazy">
    <lst name="defaults">
      <!-- All the main content goes into this field... if you need to
return
           the extracted text or do highlighting, use a stored field. -->
      <str name="map.content">text</str>
      <str name="lowernames">true</str>
      <str name="uprefix">ignored_</str>
    </lst>
  </requestHandler>

Note that the example also shows how to use the "literal.*" parameter to add
metadata fields of your choice to the document.

Hope that helps get you started.
