Package tika provides a client and server for downloading, starting, and using Apache Tika's (http://tika.apache.org) Server.
|
|
|
|
Start with basic imports:
|
|
|
|
import "github.com/google/go-tika/tika"
|
|
|
|
You will need a running Server to make API calls to. So, if you don't
|
|
have a server that is already running, and you don't have the Server
|
|
JAR already downloaded, you can download one. The caller is responsible
|
|
for removing the file when no longer needed.
|
|
|
|
Version is a custom type, and should be passed as such. There are constants in the code for these.
|
|
The following example downloads version 1.21 to the named JAR in the
|
|
current working directory.
|
|
|
|
err := tika.DownloadServer(context.Background(), tika.Version121, "tika-server-1.21.jar")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
If you don't have a running Tika Server, you can start one.
|
|
|
|
// Optionally pass a port as the second argument.
|
|
s, err := tika.NewServer("tika-server-1.21.jar", "")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
err := s.Start(context.Background())
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer s.Stop()
|
|
|
|
To parse the contents of a file (or any io.Reader), you will need to open the io.Reader,
|
|
create a client, and call client.Parse.
|
|
|
|
// import "os"
|
|
f, err := os.Open("path/to/file")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer f.Close()
|
|
|
|
client := tika.NewClient(nil, s.URL())
|
|
body, err := client.Parse(context.Background(), f)
|
|
|
|
If you pass an *http.Client to tika.NewClient, it will be used for all requests.
|
|
|
|
Some functions return a custom type, like Parsers(), Detectors(), and
|
|
MIMETypes(). Use these to see what features are supported by the current
|
|
Tika server.
