Java 使用httpClient 发送post请求 携带四个参数 String domainId,String tableName,String date,String keyword

可以使用以下代码发送post请求并携带四个参数：

import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClients;

import java.io.IOException;

public class HttpClientExample {
    public static void main(String[] args) throws IOException {
        HttpClient httpClient = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost("http://example.com");

        // 设置参数
        String domainId = "your_domain_id";
        String tableName = "your_table_name";
        String date = "your_date";
        String keyword = "your_keyword";

        String json = String.format("{\"domainId\":\"%s\",\"tableName\":\"%s\",\"date\":\"%s\",\"keyword\":\"%s\"}",
                domainId, tableName, date, keyword);
        httpPost.setEntity(new StringEntity(json));

        // 发送请求
        httpClient.execute(httpPost);
    }
}

其中，`http://example.com` 是你要发送请求的地址，`domainId`、`tableName`、`date`、`keyword` 是要携带的四个参数。将这些参数放到一个 JSON 对象中，然后将这个对象作为请求体发送。
