Table Extraction Tool Guide
Note：Before learning how to use different functions, we recommend that read the Request Workflow to know a basic PDF processing process. When using different functions, you can set their own special parameters when uploading files. Other basic steps are consistent.

import okhttp3.*;
public class main {
public static void main(String []args) throws IOException{
OkHttpClient client = new OkHttpClient().newBuilder()
.build();
MediaType mediaType = MediaType.parse("text/plain");
RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM)
.addFormDataPart("file","{{file}}",
RequestBody.create(MediaType.parse("application/octet-stream"),
new File("<file>")))
.addFormDataPart("language","{{language}}")
.addFormDataPart("password","")
.addFormDataPart("parameter","{ \"lang\": 8 }")
.build();
Request request = new Request.Builder()
.url("https://api-server.compdf.com/server/v1/process/documentAI/tableRec")
.method("POST", body)
.addHeader("x-api-key", "{{apiKey}}")
.build();
Response response = client.newCall(request).execute();
}
