## Project Overview

curl4j is a simple cURL-like Java HTTP client library providing a fluent API for building HTTP requests. It's designed to be minimal with only Apache Commons IO as a dependency.

## Directory Structure

git clone https://github.com/codelibs/fess-testdata.git
cd fess-testdata
git checkout f19176ab1b7ddc0a40393a8cbbb8d1c17b27c3ce
cd ..
popd >/dev/null

cat ${temp_log_file} ./fess-*/logs/*.log
curl -s "http://localhost:9201/_cat/indices?v"

Create NDJSON file with required Fess fields:

```json
{"url":"http://example.com/doc1","title":"Document 1","content":"Full text content...","mimetype":"text/html"}
{"url":"http://example.com/doc2","title":"Document 2","content":"More content...","mimetype":"application/pdf"}
```

**Step 3: Bulk Import**

```bash
curl -X PUT "http://localhost:8080/api/admin/documents/bulk" \

```java
import org.codelibs.curl.Curl;

Curl.post("https://api.example.com/items")
    .body("{\"name\":\"item1\"}")
    .header("Content-Type", "application/json")
    .execute(
        response -> System.out.println("Async status: " + response.getHttpStatusCode()),
        error -> error.printStackTrace());
```
