百度统计接口:登录接口,其实在数据查询时并不需要进行登录接口调用,但是需要提供百度统计账户、数据导出token、ucid(首次登录获取后存储在数据库中即可),百度接口文档中一般称之为“用户相关”。
今天我们看一下如何进行登录接口调用以及获取ucid
首先,查询百度统计登录接口文档DR-API
DR-API挂接方发送的消息应该遵循如下规范: CLIENT ID ENCRYPT VERSION RESERVED RESERVED REAL DATA 每一个消息都包含了消息头和数据。消息头由8个字节组成,分成4个整数,每个整数包含2 个字节高位在前。 第一个整数表示client id,由DR-API统一分配。 第二个整数表示encrypt version,由DR-API统一分配。 第三个和第四个整数为保留整数,暂不使用。 消息头后面紧跟着消息数据。数据采用先压缩后加密的形式: ......
最初看到这个文档时,真的觉得很头大,不知道在干嘛,其中里面包含了三个接口方法,preLogin,verifyQuestion,doLogin,而我们只需要doLogin即可。参照官方提供的demo,我总结了以下几个步骤:
1. 注册百度统计账户,确保网站昨日PV大于100,开通数据导出服务获得Token(好像有冷却时间,开通后不能立即用);2. 设置公钥key(我在项目中胡写的,但一直这么用没出啥问题),并进行RSA工具类获取公钥;3. 按照文档要求构造请求参数对象req(DoLoginRequestImpl);4. 将请求参数转换为json,并使用Gzip进行压缩;
5. 通过RSA工具类用公钥加密数据,参数为第2步获取的公钥,第4步获取的string;
6. 通过HTTP请求进行登录,返回结果数据;
7. 解压返回结果。
分享测试代码:
/** * 登陆接口 * 将登陆用户信息进行压缩加密,然后登陆 * @author shy * @date 2016-11-15 下午01:08:44 */ public static DoLoginResponse doLogin(WebsiteUser site) { try { DoLoginRequestImpl req = new DoLoginRequestImpl(); req.setPassword(site.getPassword()); req.setUsername(site.getUserName()); req.setUuid(AppConstans.UUID); req.setToken(site.getToken()); req.setFunctionName(AppConstans.LOGIN_METHOD); Key publicKey = RSAUtil.getPublicKey(AppConstans.KEY); //System.out.println("publicKey:" + publicKey ); Gson gson = new Gson(); String json = gson.toJson(req); //System.out.println("json:" + json); byte[] bytes = RSAUtil.encryptByPublicKey(GZipUtil.gzipString(json), publicKey); //System.out.println("zip:" + bytes.length); String loginResult = HttpClientUtils.doHttpPost(AppConstans.HOME_LOGIN_ADDRESS, bytes, 10000, "utf-8"); DoLoginResponse resp = gson.fromJson(loginResult, DoLoginResponse.class); return resp; } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; }
HTTP请求也比较特殊
/** * 仅用于登陆的http post请求,登陆返回结果需要解压,然后才可以返回String或者obj * @param url * @param bytes * @param timeout * @param encode * @return * @author shy * @date 2016-11-15 下午01:26:48 */ public static String doHttpPost(String url, byte[] bytes, int timeout, String encode){ HttpClient httpClient = new HttpClient(new HttpClientParams(), new SimpleHttpConnectionManager()); httpClient.getParams().setContentCharset(encode); PostMethod postMethod = new PostMethod(url); InputStream inputStream = new ByteArrayInputStream(bytes, 0, bytes.length); RequestEntity requestEntity = new InputStreamRequestEntity(inputStream, bytes.length, "text/json; charset=utf-8"); postMethod.setRequestEntity(requestEntity); postMethod.addRequestHeader("Content-Type", "text/json; charset=utf-8"); postMethod.addRequestHeader("uuid", AppConstans.UUID); postMethod.addRequestHeader("account_type", "1"); //默认是百度账号 try { httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(timeout); int num = httpClient.executeMethod(postMethod); //System.out.println(num); if (num == AppConstans.SC_OK) { //System.out.println(postMethod.getResponseBodyAsString()); InputStream in = postMethod.getResponseBodyAsStream(); try { byte[] b = new byte[8]; if (in.read(b) != 8) { throw new ClientInternalException("Server response is invalid."); } if (b[1] != 0) { throw new ClientInternalException("Server returned an error code: " + b[0]+b[1]+b[2]+b[3]+b[4]+b[5]+b[6]+b[7]); } int total = 0, k = 0; b = new byte[AppConstans.MAX_MSG_SIZE]; while (total < AppConstans.MAX_MSG_SIZE) { k = in.read(b, total, AppConstans.MAX_MSG_SIZE - total); if (k < 0) break; total += k; } if (total == AppConstans.MAX_MSG_SIZE) { throw new ClientInternalException("Server returned message too large."); } byte[] zip = ArrayUtils.subarray(b, 0, total); zip = GZipUtil.unGzip(zip); //System.out.println(JacksonUtil.str2Obj(new String(zip, "UTF-8"), DoLoginResponse.class)); //return JacksonUtil.str2Obj(new String(zip, "UTF-8"), DoLoginResponse.class); return new String(zip, "UTF-8"); } catch (IOException e) { throw new ClientInternalException(e); } finally { if (in != null) { try { in.close(); } catch (IOException e) { throw new ClientInternalException(e); } } } } } catch (Exception e) { //logger.error(e.getMessage(), e); } finally { postMethod.releaseConnection(); } return ""; }
请求参数相关实体类DoLoginRequestImpl
请求参数相关实体类AbstractLoginRequest
两个官方提供的工具类 RSAUtil,GzipUtil
几个请求方法路径参数,两个胡写的key,uuid
