httpclient发送get请求Headers传参数

使用Apache HttpClient发送GET请求时，Headers可以通过设置请求对象的addHeader方法来传递参数。下面是示例代码：

import java.io.IOException;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;

public class HttpClientGetHeadersExample {
    public static void main(String[] args) throws IOException {
        CloseableHttpClient client = HttpClients.createDefault();
        HttpGet httpGet = new HttpGet("https://www.example.com");
        httpGet.addHeader("header1", "value1");
        httpGet.addHeader("header2", "value2");
        CloseableHttpResponse response = client.execute(httpGet);
        // 处理响应结果
        response.close();
        client.close();
    }
}

在这个例子中，我们创建了一个HttpGet对象，并通过addHeader方法设置了两个header参数。使用CloseableHttpClient执行请求后，可以处理响应结果。
