java調用百度接口

jeecms框架系統調用百度統計接口
1.創建一個能調用https的工具類

package com.jeecms.common.util;
import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
// 先寫一個能調用https的工具類
public class HttpUtils {
    private static class TrustAnyTrustManager implements X509TrustManager {

        public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // TODO Auto-generated method stub

        }

        public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // TODO Auto-generated method stub

        }

        public X509Certificate[] getAcceptedIssuers() {
            // TODO Auto-generated method stub
            return null;
        }

    }

    private static class TrustAnyHostnameVerifier implements HostnameVerifier {

        public boolean verify(String arg0, SSLSession arg1) {
            // TODO Auto-generated method stub
            return false;
        }
    }

    /**
     * post方式請求服務器(https協議)
     *
     * @param url
     *            請求地址
     * @param content
     *            參數
     * @param charset
     *            編碼
     * @return
     * @throws NoSuchAlgorithmException
     * @throws KeyManagementException
     * @throws IOException
     */
    public static String  post(String url, String content, String charset)
            throws NoSuchAlgorithmException, KeyManagementException,
            IOException {
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, new TrustManager[] { new TrustAnyTrustManager() },
                new java.security.SecureRandom());

        URL console = new URL(url);
        HttpsURLConnection conn = (HttpsURLConnection) console.openConnection();
        conn.setSSLSocketFactory(sc.getSocketFactory());
        conn.setHostnameVerifier(new TrustAnyHostnameVerifier());
        conn.setDoOutput(true);
        conn.connect();
        DataOutputStream out = new DataOutputStream(conn.getOutputStream());
        out.write(content.getBytes(charset));
        // 刷新、關閉
        out.flush();
        out.close();
        InputStream is = conn.getInputStream();
        if (is != null) {
            ByteArrayOutputStream outStream = new ByteArrayOutputStream();
            byte[] buffer = new byte[1024];
            int len = 0;
            while ((len = is.read(buffer)) != -1) {
                outStream.write(buffer, 0, len);
            }
            byte data[] = outStream.toByteArray(); 
            String str = new String(data,charset); //解決輸出中文亂碼
            outStream.close();
            is.close();
            return str.toString();
        }
        return null;
    }
}

2. 調用 https://api.baidu.com/json/tongji/v1/ReportService/getData接口獲得siteId的列表
   body中method參數和metrics參數，這兩個參數官方文檔中有這裏是鏈接：
   http://tongji.baidu.com/open/api/more?p=tongjiapi_getData.tpl

package com.jeecms.cms.api.admin.main;

import com.jeecms.common.util.HttpUtils;
import org.json.JSONObject;

@Controller
public class BaiduApiContent {
    public static final String username = "";//用戶名
    public static final String password = "";//密碼
    public static final String token = "";//token值的獲取方式：百度統計頁面 -- 管理模塊 --- 數據導出服務 -- 開通token-- 獲取token值
    public static final String siteId = "";//網站地址上面就有siteid
    public static final String urlStr = "https://api.baidu.com/json/tongji/v1/ReportService/getData";
    public static final String charset = "utf-8";
    @RequestMapping(value = "/getTimeTrendRpt/list")//趨勢分析
    @ResponseBody
    public String  getTimeTrendRpt() throws Exception{
        String method="trend/time/a";
        String metrics="pv_count,visitor_count,ip_count";
        Calendar cal=Calendar.getInstance();
        cal.add(Calendar.DATE,-1);
        Date time=cal.getTime();
        String startDate=new SimpleDateFormat("yyyyMMdd").format(time);

        JSONObject header = new JSONObject();
        header.put("username", username);//用戶名
        header.put("password", password);//用戶密碼
        header.put("token", token);//申請到的token
        header.put("account_type", "1");
        JSONObject body = new JSONObject();
        body.put("siteId", siteId);
        body.put("method", method);//需要獲取的數據
        body.put("start_date", startDate);
        body.put("end_date", endDate);
        body.put("metrics", metrics); //指標，數據單位
        JSONObject params = new JSONObject();
        params.put("header", header);
        params.put("body", body);
      //  String  s = HttpUtils.post(urlStr, params.toString(), charset);
      //  String s = new String(res);
      /*      System.out.println(s);*/
        return HttpUtils.post(urlStr, params.toString(), charset);
    }
    @RequestMapping(value = "/getCommonTrackRpt/list")//來源網站、搜索詞、入口頁面、受訪頁面
    @ResponseBody
    public String  getCommonTrackRpt() throws Exception{

        String metrics="pv_count";
        Calendar cal=Calendar.getInstance();
        cal.add(Calendar.DATE,-1);
        Date time=cal.getTime();
        String startDate=new SimpleDateFormat("yyyyMMdd").format(time);
        String endDate=new SimpleDateFormat("yyyyMMdd").format(new Date());
        JSONObject header = new JSONObject();
        header.put("username", username);//用戶名
        header.put("password", password);//用戶密碼
        header.put("token", token);//申請到的token

        JSONObject body = new JSONObject();
        body.put("siteId", siteId);
        body.put("method", method);//需要獲取的數據
        body.put("start_date", startDate);
        body.put("end_date", endDate);
        body.put("metrics", metrics); //指標，數據單位
        JSONObject params = new JSONObject();
        params.put("header", header);
        params.put("body", body);
       // byte[] res = HttpUtils.post(urlStr, params.toString(), charset);
       // String s = new String(res);
           /* System.out.println(s);*/
        return HttpUtils.post(urlStr, params.toString(), charset);
    }
    @RequestMapping(value = "/getDistrictRpt/list")//地域分佈)
    @ResponseBody
    public String  getDistrictRpt() throws Exception{
        String method="overview/getDistrictRpt";
        String metrics="pv_count";
        Calendar cal=Calendar.getInstance();
        cal.add(Calendar.DATE,-1);
        Date time=cal.getTime();
        String startDate=new SimpleDateFormat("yyyyMMdd").format(time);
        String endDate=new SimpleDateFormat("yyyyMMdd").format(time);
            JSONObject header = new JSONObject();
            header.put("username", username);//用戶名
            header.put("password", password);//用戶密碼
            header.put("token", token);//申請到的token
            header.put("account_type", "1");

            body.put("siteId", siteId);
            body.put("method", method);//需要獲取的數據
            body.put("start_date", startDate);

            body.put("metrics", metrics); //指標，數據單位
            JSONObject params = new JSONObject();
            params.put("header", header);
            params.put("body", body);
           //byte[] res = HttpUtils.post(urlStr, params.toString(), charset);
           // String s = new String(res);
           /* System.out.println(s);*/
        return HttpUtils.post(urlStr, params.toString(), charset);
    }

}

3.配置xml文件

<bean id="baiduApiContent" class="com.jeecms.cms.api.admin.main.BaiduApiContent"/>

4.vue獲取接口返回的json數據進行數據截取 並在頁面展示出來
