HttpClient 模拟登录搜狐微博

第一次遇到一个这样的问题，"PKIX path building failed" 异常

 

详解异常: http://www.cnblogs.com/aurawing/articles/1899217.html

 

大概意思是，证书出问题了，服务器不信任我们自己创建的证书。

两种解决方法

     1.请求时添加代码忽略证书信任问题

          我用httpClient，简单明了的两句代码(支持SSL，也就是以https://开头的，一般是http://)

                  Protocol myhttps = new Protocol("https", new MySecureProtocolSocketFactory(), 443);

                  Protocol.registerProtocol("https", myhttps);

     2.代码控制证书生成，导入，再请求

 

 

成功例子：

      private static void testLogin()

      {

            try

            {

                  String callback_url = "http://www.wedfvd.com";

                  

                  TSohu tsohu = new TSohu(AConstants.TSOHU_APP_KEY,AConstants.TSOHU_APP_KEY_SECRET);

                  

                  TSohuOAuthClient oc = new TSohuOAuthClient();//OAuth认证授权以及签名相关

                  TSohuOAuth requestOAuth = oc.requestToken(tsohu);

                  //hd=default&

//                String authorizeUrl = "http://api.t.sohu.com/oauth/authorize?oauth_token="

//                            + requestOAuth.getOauth_token() + "&oauth_callback=" + callback_url;

                  

                  HttpClient httpClient = new HttpClient();

                  

                  String loginUrl = "https://passport.sohu.com/sso/login.jsp?appid=1073&persistentcookie=1&s="+new Date().getTime()+"&b=6&w=1024&pwdtype=1&v=26";

                  loginUrl += "&userid="+URLEncoder.encode("zzzzzzzzzzzz@sohu.com", "utf-8")+"&password="+MD5Util.encrypt("123456");

                  

                  Protocol myhttps = new Protocol("https", new MySecureProtocolSocketFactory(), 443);

                  Protocol.registerProtocol("https", myhttps);

                  

                  GetMethod get = new GetMethod(loginUrl);

                  int status = httpClient.executeMethod(get);

//                System.out.println(status+" "+get.getResponseBodyAsString());

                  

                  PostMethod post = new PostMethod("http://api.t.sohu.com/oauth/authorize");

                  post.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler());

                  post.getParams().setParameter("http.protocol.cookie-policy", CookiePolicy.BROWSER_COMPATIBILITY);

                  post.getParams().setParameter("http.protocol.single-cookie-header", true);

                  

                  NameValuePair[] params = new NameValuePair[]{

                              new NameValuePair("oauth_token", requestOAuth.getOauth_token()),

                              new NameValuePair("oauth_callback", callback_url)

                  };

                  post.setRequestBody(params);

                  

                  int statusCode = httpClient.executeMethod(post);

//                String response = post.getResponseBodyAsString();

//                System.out.println(statusCode+" "+response);

                  

                  if (post.getResponseHeader("Location") != null) {

                        String location = post.getResponseHeader("Location").getValue();

                        String oauthVerifier = StringUtils.substringAfter(location, "oauth_verifier=");

//                      System.out.println(oauthVerifier);

                        

                        requestOAuth.setOauth_verifier(oauthVerifier);

                        TSohuOAuth accessOAuth = oc.accessToken(requestOAuth);

                        

                        TSohuAccessToken accessToken = new                TSohuAccessToken(accessOAuth.getOauth_token(),accessOAuth.getOauth_token_secret());

                        tsohu.setToken(accessToken);

                        

                        User user = tsohu.verify_credentials();

                        

                        accessToken.setUserid(Long.valueOf(user.getId()));

                        accessToken.setScreen_name(user.getScreenName());

                        

                        System.out.println("搜狐微博用户"+user.getScreenName()+"授权码：");

                        System.out.println("token："+accessToken.getToken());

                        System.out.println("tokenSecret："+accessToken.getTokenSecret());

                  } else {

                        if (statusCode != 200) {

                              throw new RuntimeException("访问网络资源出现问题，错误码为： " + statusCode);

                        }

                  }

            } catch (Exception e)

            {

                  e.printStackTrace();

            }

      }
