Upload file to s3 using presigned post url

[Fernandez]

Hi,

I found the java routine below for uploading file using presigned post URL :

I have downloaded the package httpcomponents-client-5.3.1-bin.tar.gz for uploading the jar below : 

I uploaded the .jar in the project : 

Do you know why I get the errors as you can see in the first picture ?

The import org.apache.http cannot be resolved

HttpClient cannot be resolved to a type

Thanks for your help

Hi,

I found another script that is working : 

package routines;

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.OutputStream;

import java.net.HttpURLConnection;

import java.net.URL;

public class WebServices {

    public static void main(String[] args) {

        String presignedUrl = "YOUR_PRESIGNED_URL_HERE"; // Replace with your presigned URL

        String filePath = "path/to/your/file.txt"; // Replace with the path to your file

        try {

            uploadFile(presignedUrl, filePath);

            System.out.println("File uploaded successfully.");

        } catch (IOException e) {

            e.printStackTrace();

        }

    }

    public static void uploadFile(String presignedUrl, String filePath) throws IOException {

        File file = new File(filePath);

        if (!file.exists() || !file.isFile()) {

            throw new IOException("File does not exist or is not a valid file.");

        }

        URL url = new URL(presignedUrl);

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        connection.setRequestMethod("PUT");

        connection.setDoOutput(true);

        connection.setRequestProperty("Content-Type", "application/octet-stream");

        connection.setRequestProperty("Content-Length", String.valueOf(file.length()));

        try (FileInputStream fis = new FileInputStream(file);

             OutputStream os = connection.getOutputStream()) {

            byte[] buffer = new byte[4096];

            int bytesRead;

            while ((bytesRead = fis.read(buffer)) != -1) {

                os.write(buffer, 0, bytesRead);

            }

            os.flush();

        }

        int responseCode = connection.getResponseCode();

        if (responseCode != HttpURLConnection.HTTP_OK && responseCode != HttpURLConnection.HTTP_CREATED) {

            throw new IOException("Failed to upload file. HTTP response code: " + responseCode);

        }

    }

}
