curl to Java

Convert curl commands to Java OkHttp code. Supports headers, POST data, auth, and common flags.

curl command

Java (OkHttp)

import okhttp3.*;

public class Main {
    public static void main(String[] args) throws Exception {
        OkHttpClient client = new OkHttpClient();

        RequestBody requestBody = RequestBody.create(
            "{\"name\":\"Alice\",\"email\":\"alice@example.com\"}",
            MediaType.parse("application/json")
        );

        Request request = new Request.Builder()
            .url("https://api.example.com/users")
            .method("POST", requestBody)
            .addHeader("Content-Type", "application/json")
            .addHeader("Authorization", "Bearer token123")
            .build();

        Response response = client.newCall(request).execute();
        System.out.println(response.code());
        System.out.println(response.body().string());
    }
}

curl to Java OkHttp

OkHttp is the most widely used HTTP client for Java and Android. This converter maps curl flags to their OkHttp equivalents: -H becomes .addHeader(), -d maps to RequestBody.create(), and -u generates a Base64-encoded Authorization header. All processing runs entirely in your browser.
