在OkHttp中的请求之间交换cookies

import okhttp3.*;

class MyCookieJar implements CookieJar {
    private List<Cookie> cookies;

    @Override
    public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {
        this.cookies = cookies;
    }

    @Override
    public List<Cookie> loadForRequest(HttpUrl url) {
        if (cookies != null) {
            return cookies;
        }
        return new ArrayList<>();
    }
}

public class Main {
    public static void main(String[] args) {
        OkHttpClient client = new OkHttpClient.Builder()
                .cookieJar(new MyCookieJar())
                .build();

        // 发送请求
        Request request = new Request.Builder()
                .url("https://example.com")
                .build();

        try (Response response = client.newCall(request).execute()) {
            // 处理响应
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
