时间信息实现

由于每次访问都有获取token，所以就写了一个工具类

String getToken(String xh,String pwd) 获取token值

import net.sf.json.JSONObject;
import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
import java.net.URISyntaxException;

public class Data {

    public String getToken(String xh,String pwd) throws URISyntaxException, IOException {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        URIBuilder uriBuilder = new URIBuilder("http://zswxyjw.minghuaetc.com/znlykjdxswxy/app.do");
        uriBuilder.setParameter("method","authUser").setParameter("xh",xh).setParameter("pwd",pwd);
        HttpGet httpGet = new HttpGet(uriBuilder.build());
        CloseableHttpResponse response = httpClient.execute(httpGet);
        String s = null;
        if(response.getStatusLine().getStatusCode()==200){
            HttpEntity entity = response.getEntity();
            s = EntityUtils.toString(entity, "utf-8");
        }
        JSONObject obj = new JSONObject();
        obj = obj.fromObject(s);
        Object token = obj.get("token");
        return  token.toString();
    }

}

　　

数据的获取

强智的API返回的是一个JOSN文件，通过火狐浏览器可以直接解析

• 代码实现
  1.导入jar包
  2.代码实现

if(response.getStatusLine().getStatusCode()==200){
            HttpEntity entity = response.getEntity();
            s = EntityUtils.toString(entity, "utf-8");
        }
        JSONObject obj = new JSONObject();
        obj = obj.fromObject(s);
        Object token = obj.get("token");

　　

我创建的是Maven项目，所以jar包只需要在配置文件中加入配置信息即可

时间信息的具体实现

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.IOException;
import java.net.URISyntaxException;

public class Test2 {
    public static void main(String[] args) throws URISyntaxException, IOException {
        String token = new Data().getToken("学号","密码");

        CloseableHttpClient httpClient = HttpClients.createDefault();
        URIBuilder uriBuilder = new URIBuilder("http://zswxyjw.minghuaetc.com/znlykjdxswxy/app.do");
        uriBuilder.setParameter("method","getCurrentTime").setParameter("currDate","2019-05-27");//YYYY-MM_DD  这里特别注意，MM DD一定要两位数，不足前面补零
        HttpGet httpGet = new HttpGet(uriBuilder.build());
        httpGet.setHeader("token",token);
        CloseableHttpResponse response = httpClient.execute(httpGet);
        String s = null;
        if(response.getStatusLine().getStatusCode()==200){
            HttpEntity entity = response.getEntity();
            s = EntityUtils.toString(entity, "utf-8");
            System.out.println(s);
        }
    }
}
