php 新浪通行证登录 新浪微博登录 模拟登录 (浏览器版) 2016
由于需要项目需要管理微博平台内容，集成登录微博管理平台功能，所以在抓取网页基础上探索了一下浏览器模拟登录，已经实现登录功能，采用JQuery和php结合的方式实现的，其中需要注意跨域访问问题，还要注意下面是在phpcms中的，如果大家是单独php项目，把访问本地项目就是APP_PATH那个东西和index?m=x&c=xx&a=xx换成自己对应那个链接，a代表执行的方法，c代表执行的类，m代表模块。
新浪登录认证流程：
1.预登陆获取pubkey/nonce/rsak等用于加密用户信息(get)。返回json
2.login.php?client=ssologin对用户账号进行加密用户名采用base64加密，密码采用rsa2加密，rsa2加密是sina提供的js中加密方法(post)。返回json，cookie
3.第2步中返回的json包含若干个url，crossDomainUrl是用于SSO统一登录的，分别参照下面代码发送请求方式及参数将crossDomainUrl请求一次，获取cookie即可(get)。返回json，cookie
4.登录成功。
代码如下：
'login.sina.com.cn',
'User-Agent' => 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0',
'Accept' => '*/*',
'Accept-Language' => 'zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3',
'Accept-Encoding' => 'gzip, deflate',
'Referer' => 'http://login.sina.com.cn/',
'Connection' => 'keep-alive'
);
//base64加密后用户名
private $su = '';
//js加密后的密码
private $sp = '';
function __construct() {
}
//预登陆,浏览器直接访问该方法，登录方法入口，通过调用该方法来登录，该方法调用或间接调用了其他方法。
function pre_login() {
// 用户名称base64加密-用于预登陆
$this->su = base64_encode ( urlencode ( $this->username ) );
