微博登录php
‘壹’ 用官网的php SDK做的微博登录API，登录后一直出现500错误，求解（下面是callback的代码）
500是服务端错误了
‘贰’ 如果用php语言获取新浪微博某一网址的源码
我试着用file_get_contents()来获取了一下，是能获取到源码的。
var_mp((file_get_contents('http://weibo.com/p/1005051893289714/')));不过确实显示的如你说的那样，只有页面title显示为“Sina Visitor System”，但是这个时候，因为使用了var_mp()来打印，可以看到页面上还显示了：string(5405) ""。
这说明file_get_contents返回了还是比较多的内容，再来查看一下源代码，发现返回的是一些js语句，这些语句当然是不会显示在页面上的，里面还有外部js，那么你获得源码之后，因为js路径不对(它使用的是相对地址)，所以也会引起js报错，而导致js没有运行：
<scripttype="text/javascript"src="/js/visitor/mini.js"></script>
正常情况下，我们打开http://weibo.com/p/1005051893289714/这个网页之后，看到的其实是这个js执行之后的跳转页面。
‘叁’ 如何获取新浪微博的登录参数
1、用Chrome的开发者工具或者Firefox的Firebug来进行抓包
找到login.php文件，就可以看到此文件的一些请求参数，

‘肆’ 新浪微博网站接入，怎么实现接入网站的
有一个代码，加进来就可以了，需要你程序员添加
‘伍’ php让用户使用新浪微博账号登录我的网站一般要保存那些参数到数据库
uid针对你的网站是固定的，access_token可以说不是固定的，但是有效期很长，他是用来确定用户授权的有效期，具体可参见官方文档。
access_token
用于调用access_token，接口获取授权后的access
token。
expires_in
access_token的生命周期，单位是秒数。
remind_in
access_token的生命周期（该参数即将废弃，开发者请使用expires_in）。
uid
，当前授权用户的UID。
