通过GAE平台自动发布文章到百度空间

昨天写了一篇通过Java程序自动发送文章到百度空间，具体实现原理和代码请参照

《Java程序自动发布文章到百度空间》

 

今天把那版代码进行了更新，现在可以放置到GAE平台了，这样基于GAE平台环境搭建的个人博客就可以

很方便的将个人的博文同步到百度空间。

 

具体的实现原理现在不多说了，现在展示一下核心代码：

1. Config.Java  

    配置个人百度空间的账户名和密码

  

package com.carey.baidublog;public class Config {	public static final String USERNAME = "username";	public static final String PASSWORD = "password";}

2. GAEPublishBaiduActicleServlet.java

   用来处理GAE的servlet请求

  

package com.carey.gae.baidu;import java.io.IOException;import javax.servlet.http.*;import com.carey.baidublog.BDHttpClient;public class GAEPublishBaiduActicleServlet extends HttpServlet {	private static final long serialVersionUID = 1L;	public void doGet(HttpServletRequest req, HttpServletResponse resp)			throws IOException {		try {			BDHttpClient					.publishBlog("gae-title", "gae-content", "gae-category");		} catch (Exception e) {			e.printStackTrace();		}		resp.setContentType("text/plain");		resp.getWriter().println("成功发布一篇博文到百度空间");	}}

3.  BDHttpClient.java

  完成百度博文的发布

 

package com.carey.baidublog;import java.net.URL;import java.util.HashMap;import java.util.Set;import java.util.regex.Matcher;import java.util.regex.Pattern;import javax.servlet.http.HttpServletResponse;import com.google.appengine.api.urlfetch.HTTPHeader;import com.google.appengine.api.urlfetch.HTTPMethod;import com.google.appengine.api.urlfetch.HTTPRequest;import com.google.appengine.api.urlfetch.HTTPResponse;import com.google.appengine.api.urlfetch.URLFetchService;import com.google.appengine.api.urlfetch.URLFetchServiceFactory;public class BDHttpClient {	private static final String LOGIN_URL = "https://passport.baidu.com/?login";	private static final String CREATBLOG_URL = "http://hi.baidu.com/"			+ Config.USERNAME + "/creat/blog";	private static final String MODIFYCATEGORY_URL = "http://hi.baidu.com/"			+ Config.USERNAME + "/modify/category/0";	private static final String COMMITBLOG_URL = "http://hi.baidu.com/"			+ Config.USERNAME + "/commit";	private static final URLFetchService urlFetchService = URLFetchServiceFactory			.getURLFetchService();	private static final HashMap globalCookies = new HashMap();	public static void publishBlog(String title, String content, String category)			throws Exception {		// step 1, login baidu and get cookies		String cookies = LoginBaidu();		// step 2, get Bdstoken		String bdstoken = getBdstoken(cookies);		// step 3, publish article		if (bdstoken != null) {			postBlog(cookies, bdstoken, title, content, category);		} else {			throw new Exception("bdstoken == null");		}	}	private static String LoginBaidu() {		HashMap params = new HashMap();		params.put("username", Config.USERNAME);		params.put("password", Config.PASSWORD);		params.put("pwd", "1");		try {			httpPost(null, LOGIN_URL, generateQueryString(params));		} catch (Exception e) {			e.printStackTrace();		}		return globalCookies.get("set-cookie");	}	private static String getBdstoken(String cookies) {		try {			String res = httpGet(cookies, CREATBLOG_URL, null);			Pattern p = Pattern.compile("bdstoken=([0-9a-z]+)\\W");			Matcher m = p.matcher(res);			if (m.find()) {				return m.group(1);			}		} catch (Exception e) {			e.printStackTrace();		}		return null;	}	private static String createCategory(String cookies, String bdstoken,			String category) throws Exception {		HashMap params = new HashMap();		// bdstoken		params.put("bdstoken", bdstoken);		// create category		params.put("ct", "2");		params.put("cm", "1");		// Article category, such as "Android", "Google", "默认分类"		params.put("spBlogCatName", category);		params.put("spRefURL", MODIFYCATEGORY_URL);		return httpPost(cookies, COMMITBLOG_URL, generateQueryString(params));	}	private static String postBlog(String cookies, String bdstoken,			String title, String content, String category) throws Exception {		HashMap params = new HashMap();		// bdstoken		params.put("bdstoken", bdstoken);		// new blog		params.put("ct", "1");		params.put("cm", "1");		// add a new article		params.put("spBlogID", "");		params.put("edithid", "");		params.put("spBlogCatName_o", "");		// Article title		params.put("spBlogTitle", title);		// Article content		params.put("spBlogText", content);		// Article category, such as "Android", "Google", "默认分类"		params.put("spBlogCatName", category);		// Article view Permissions,		// 0 --> every one 1 --> only friend 3 --> only oneself		params.put("spBlogPower", "0");		// 0: forbidden comment 1: allow comment		params.put("spIsCmtAllow", "1");		// 0: allow share 1: forbidden share		params.put("spShareNotAllow", "0");		// verify code		params.put("spVcode", "");		params.put("spVerifyKey", "");		// first create category		createCategory(cookies, bdstoken, category);		return httpPost(cookies, COMMITBLOG_URL, generateQueryString(params));	}	private static String generateQueryString(HashMap params) {		StringBuffer sb = new StringBuffer();		if (params != null && !params.isEmpty()) {			Set keys = params.keySet();			for (String key : keys) {				sb.append(key);				sb.append("=");				sb.append(params.get(key));				sb.append("&");			}			// remove last &			sb.deleteCharAt(sb.length() - 1);		}		return sb.toString();	}	private static String httpGet(String cookies, String url, String queryString)			throws Exception {		String ret = null;		if (queryString != null && !queryString.equals("")) {			url += "?" + queryString;		}		final HTTPRequest request = new HTTPRequest(new URL(url));		if (cookies != null) {			request.setHeader(new HTTPHeader("Cookie", cookies));		}		try {			final HTTPResponse response = urlFetchService.fetch(request);			if (HttpServletResponse.SC_OK != response.getResponseCode()) {				System.err.println("HttpGet Method failed: "						+ response.getResponseCode());			}			ret = new String(response.getContent(), "UTF-8");		} catch (Exception e) {			throw new Exception(e);		}		return ret;	}	private static String httpPost(String cookies, String url,			String queryString) throws Exception {		String ret = null;		final HTTPRequest request = new HTTPRequest(new URL(url),				HTTPMethod.POST);		request.setHeader(new HTTPHeader("Content-Type",				"application/x-www-form-urlencoded"));		if (cookies != null) {			request.setHeader(new HTTPHeader("Cookie", cookies));		}		if (queryString != null && !queryString.equals("")) {			request.setPayload(queryString.getBytes("UTF-8"));		}		try {			final HTTPResponse response = urlFetchService.fetch(request);			if (HttpServletResponse.SC_OK != response.getResponseCode()) {				System.err.println("HttpPost Method failed: "						+ response.getResponseCode());			}			// Get site cookie			for (HTTPHeader header : response.getHeaders()) {				if (header.getName().equalsIgnoreCase("set-cookie")) {					globalCookies.put("set-cookie", header.getValue());				}			}			ret = new String(response.getContent(), "UTF-8");		} catch (Exception e) {			throw new Exception(e);		}		return ret;	}}

以上程序在GAE环境测试通过，运行过程序后会自动在百度空间发布一篇文章，截图如下：
