使用HttpClient传递多个简单参数

java

import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
import java.util.ArrayList;
import java.util.List;
public class HttpClientExample {
    public static void main(String[] args) {
        // 创建HttpClient对象
        HttpClient httpClient = HttpClientBuilder.create().build();
        // 创建HttpPost对象
        HttpPost httpPost = new HttpPost("http://example.com/submit");
        // 设置参数
        List params = new ArrayList<>();
        params.add(new BasicNameValuePair("username", "admin"));
        params.add(new BasicNameValuePair("password", "123456"));
        params.add(new BasicNameValuePair("email", "admin@example.com"));
        try {
            httpPost.setEntity(new UrlEncodedFormEntity(params));
            // 执行请求
            HttpResponse response = httpClient.execute(httpPost);
            // 获取响应内容
            String responseBody = EntityUtils.toString(response.getEntity());
            System.out.println(responseBody);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
