本文介绍了一个用于从51job和智联招聘抓取个人简历的小项目中的模拟登录实现方法。通过使用Java语言及Apache HttpClient库，文中提供了一段代码示例，展示了如何创建一个信任所有HTTPS证书的客户端，以便绕过安全验证进行模拟登录。

最近在写一个小项目，需要去51job和智联上抓取个人简历，所以就需要模拟登录。。真真是折腾了一番啊，不过对于http倒是多了一点了解。不多说，先copy代码，还要接着去写呢。

};
ctx.init(null, new TrustManager[] { tm }, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx);
ssf
.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", ssf, 443));
return new DefaultHttpClient(ccm, base.getParams());
} catch (Exception ex) {
ex.printStackTrace();
return null;
}
}
}
