用OkHttp在Java中实现网址编码

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

import java.io.IOException;
import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;

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

        try {
            // 原始 URL
            String baseUrl = "https://example.com/search?q=";
            String query = "Java 编程";

            // 对查询参数进行 URL 编码
            String encodedQuery = URLEncoder.encode(query, StandardCharsets.UTF_8.toString());

            // 构建完整的 URL
            String url = baseUrl + encodedQuery;

            // 创建请求
            Request request = new Request.Builder()
                    .url(url)
                    .build();

            // 发送请求并获取响应
            try (Response response = client.newCall(request).execute()) {
                if (response.isSuccessful()) {
                    System.out.println(response.body().string());
                } else {
                    System.out.println("请求失败: " + response.code());
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
