In this guide, we'll show you how to convert raw HTML to PDF using Java and the HttpClient library.
Converting raw HTML content to PDF is useful when you have HTML content that isn't hosted on a web server.
```java
import java.net.http.*;
import java.net.URI;
import java.net.http.HttpRequest.BodyPublishers;
import java.net.http.HttpResponse.BodyHandlers;
import java.time.Duration;
// You can get an API key at https://pdfshift.io
String apiKey = "sk_xxxxxxxxxxxx";
HttpClient client = HttpClient.newBuilder()
.connectTimeout(Duration.ofSeconds(10))
.build();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("https://api.pdfshift.io/v3/convert/pdf"))
.header("X-API-Key", apiKey)
.header("Content-Type", "application/json")
.POST(BodyPublishers.ofString("{\n" +
" \"source\": \"Hello World
\"\n" +
"}"))
.build();
HttpResponse response = client.send(request, BodyHandlers.ofByteArray());
// Handle errors:
if (response.statusCode() >= 400) {
throw new RuntimeException("Request failed with status code " + response.statusCode());
}
java.nio.file.Files.write(java.nio.file.Paths.get("result.pdf"), response.body());
System.out.println("The PDF document was generated and saved to result.pdf");
```
This allows you to convert HTML content directly to PDF without needing a URL.
