java实现百度统计api调用

**公司需要调用百度统计的api，昨天搞了一天，先看了百度统计的官方文档 emmmmmmm 是真的没怎么看懂，然后在网上搜了各位大牛的实现，最后自己尝试了一下访问成功！**

思路大概是这样的
1、先写一个能调用https的 java类
2、调用 https://api.baidu.com/json/tongji/v1/ReportService/getSiteList 接口获得siteId的列表
3、调用 https://api.baidu.com/json/tongji/v1/ReportService/getData 获得你需要的统计数据

首先是访问https的类(网上找大牛copy的):
类名 HttpsUtil

package com.cutc.baiduapi;

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;

public class HttpsUtil {
    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方式请求服务器(https协议) 
     *  
     * @param url 
     *            请求地址 
     * @param content 
     *            参数 
     * @param charset 
     *            编码 
     * @return 
     * @throws NoSuchAlgorithmException 
     * @throws KeyManagementException 
     * @throws IOException 
     */  
    public static byte[] 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、关闭  
        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);  
            }  
            is.close();  
            return outStream.toByteArray();  
        }  
        return null;  
    }  

}

然后需要访问获得siteId的方法:

package com.cutc.baiduapi;

import org.json.JSONObject;

public class TjApi {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            JSONObject header = new JSONObject();
            header.put("username", "");//用户名
            header.put("password", "!");//用户密码
            header.put("token", "");//申请到的token
            header.put("account_type", "1");

            String urlStr = "https://api.baidu.com/json/tongji/v1/ReportService/getSiteList";
            String charset = "utf-8";

            JSONObject params = new JSONObject();
            params.put("header", header);

            byte[] res = HttpsUtil.post(urlStr, params.toString(), charset);
            String s = new String(res);
            System.out.println(s);    
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }

    }

}

返回的数据这样的:

{
    "header":{
        "desc":"success",
        "failures":[

        ],
        "oprs":1,
        "succ":1,
        "oprtime":0,
        "quota":1,
        "rquota":49992,
        "status":0
    },
    "body":{
        "data":[
            {
                "list":[
                    {
                        "status":0,
                        "create_time":"2017-04-26 17:25:10",
                        "domain":"tourforce.asia",
                        "site_id":10646729,
                        "sub_dir_list":[

                        ]
                    }
                ]
            }
        ]
    }
}

这里就可以获取到我们需要的site_id
然后再去请求这个site_id的数据:

package com.cutc.baiduapi;

import org.json.JSONObject;

public class TjApi {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            JSONObject header = new JSONObject();
            header.put("username", "");//用户名
            header.put("password", "");//用户密码
            header.put("token", "");//申请到的token
            header.put("account_type", "1");

//          String urlStr = "https://api.baidu.com/json/tongji/v1/ReportService/getSiteList";
            String urlStr = "https://api.baidu.com/json/tongji/v1/ReportService/getData";
            String charset = "utf-8";


            JSONObject body = new JSONObject();
            body.put("siteId","10646729");
            body.put("method","overview/getTimeTrendRpt");//需要获取的数据
            body.put("start_date","20171220");
            body.put("end_date","20171222");
            body.put("metrics","pv_count,visitor_count,ip_count");//指标,数据单位

            JSONObject params = new JSONObject();
            params.put("header", header);
            params.put("body", body);

            byte[] res = HttpsUtil.post(urlStr, params.toString(), charset);
            String s = new String(res);
            System.out.println(s);

        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }

    }

}

获取到的数据如下：

{
    "header":{
        "desc":"success",
        "failures":[

        ],
        "oprs":1,
        "succ":1,
        "oprtime":0,
        "quota":1,
        "rquota":49989,
        "status":0
    },
    "body":{
        "data":[
            {
                "result":{
                    "items":[
                        [
                            [
                                "2017/12/20"
                            ],
                            [
                                "2017/12/21"
                            ],
                            [
                                "2017/12/22"
                            ]
                        ],
                        [
                            [
                                17694,
                                8811,
                                8450
                            ],
                            [
                                17271,
                                8435,
                                7996
                            ],
                            [
                                17169,
                                8306,
                                8029
                            ]
                        ],
                        [

                        ],
                        [

                        ]
                    ],
                    "timeSpan":[
                        "2017/12/20 - 2017/12/22"
                    ],
                    "fields":[
                        "simple_date_title",
                        "pv_count",
                        "visitor_count",
                        "ip_count"
                    ]
                }
            }
        ]
    }
}

这样就获取到了PV,UV,IP
最后说一下body中method参数和metrics参数，这两个参数官方文档中有这里是链接：
