Java HttpClient PostMethod

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
import org.junit.Test;

/**
 * @author ceshi
 * @Title: JunitTest
 * @ProjectName test
 * @Description: TODO
 * @date 2018/6/1416:39
 */
public class JunitTest {
    @Test
    public void test(){
        HttpClientPostMethod("http://localhost:8080/test/api","你好");
    }


    public String  HttpClientPostMethod(String url,String data){
        //1.创建 HttpClient
        HttpClient httpClient = new HttpClient();
        // 2.构造PostMethod的实例
        PostMethod postMethod = new PostMethod(url);
        //3.请求参数
        postMethod.addParameter("data", data);
        String responseMsg = "";
        try {
            httpClient.executeMethod(postMethod);
            responseMsg = postMethod.getResponseBodyAsString().trim();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 4.释放连接
            postMethod.releaseConnection();
        }
        return  responseMsg;
    }

}
