众所周知（至少对于用百度作为第三方平台的人是的），百度账号登陆是真的很容易申请到一个id，但是，他有一个问题，就是：

很容易出错

我做这个东西的时候，至少弄出了不下十个错误。现在，我就告诉大家这些问题如何解决
1、百度开发者管理中心怎么进
回答：不要指望在百度上能直接找到连接，你只能点击下方链接进入，也不要指望在百度开发者中心主页进入，更不要指望着自己乱猜网址。
连接：http://developer.baidu.com/console#app/project点击此处跳转

（你要是乱打网址进去了，那么：欧皇，请受我一拜！）
2、怎么创建应用

点击创建工程（若按钮被百度隐藏，请点击此处或复制下方链接http://developer.baidu.com/console#app/create)

按提示填写相关信息
至此，创建工程就可以了

3、怎么登陆
这个问题可算是折腾我半天了。
1、初始设置

点击你要进入的工程

按图示填写信息，然后点击保存

====================
至此，你已经搞定了后台工作

====================
废话不多说，php代码直接上
1、注册（我是在注册时强制绑定百度账号的，但是如果你只是想作为一种第三方登陆工具，也可以参考，你可以只看获取code和access_token的部分

<?php//常量设置
header("charset=utf-8");//连接数据库$con = mysql_connect("localhost","这里填账号",这里填密码);if (!$con){die('Could not connect: ' . mysql_error());}mysql_select_db("sfydb_6273437", $con);//这说明是传回了code

}
?>

2、登陆

<?php//常量设置
$con = mysql_connect("localhost","这里填写账号",这里填写密码);
if (!$con)
{die('Could not connect: ' . mysql_error());
}
mysql_select_db("sfydb_6273437", $con);
Login();//主函数
function Login()
{$Password=decryptForDotNet($_GET['Password'],"AA");$Userid=$_GET['Userid'];$result = mysql_query("SELECT * FROM userlist where Userid = '".$Userid."'");$count=mysql_num_rows($result);if($count==0){die("NoUser");}$row = mysql_fetch_array($result);if($row['Password']!=$_GET['Password']){die("WrongPassword");}if($row['BaiduUid']==""){die("NoToken.PleaseUseRegister");}//生成Cookie$Cookie = '';for ($i=1;$i<=1024;$i++){    $randstr = chr(rand(97,122));$Cookie .= $randstr; }$Cookie =encryptForDotNet($Cookie,"t68[]a*G");mysql_query("UPDATE userlist SET Cookie = '.$Cookie.' WHERE Userid='".$Userid."'");die("=".$Cookie);
}
//加密
function encryptForDotNet($input, $key)
{$iv = $key;$addnum = 8 - ( strlen($input) % 8 );for ($i = 0; $i < $addnum; $i++){$input .= chr($addnum);}$output = mcrypt_encrypt(MCRYPT_DES, $key, $input, MCRYPT_MODE_CBC, $iv);return base64_encode($output);
}
//解密
function decryptForDotNet($input, $key)
{$iv = $key;$output = base64_decode($input);$output = mcrypt_decrypt(MCRYPT_DES, $key, $output, MCRYPT_MODE_CBC, $iv);for ($i = 0; $i <= 8; $i++){$output = str_replace(chr($i), "", $output);}return $output;
}
?>

至此，后端搞定

至此，前端搞定

好啦，现在你可以用百度账号登陆啦

4、根域名相同但是还是redirect_uri错误
回答：别想啦，根域名验证是没用的，只能通过校验回调页来搞

5、为什么没有uid
回答：很简单，百度的文档太久了，实际获得的是openid而不是uid

6、如何获得code
回答：这是通过将code追加在redir_uri之后并重定向到这个uri来实现，所以你需要一个页面来接受这个code

7、redir_uri后面能带参数吗
回答：能，这个百度还是做得到的，他会用&code=xxx的形式追加

8、如何获得code
回答：其实没有百度说的那么复杂，就是将内容直接发回给当前网址，你可以像发送POST或GET请求一样，直接获取返回的json包。但你需要注意，这里的redirect_uri必须和code中的redirect_uri的网址一样（不包括参数），建议直接将获取code与获取token放在一个网址中（我就是这么做的）

9、可以正常获取code，但是得不到token
回答：token中的redirect_uri必须是获取code时填写的uri
例如：在您获取code时输入http://sscczzjj.top/作为redirect_uri，那么在你获取token也要用http://sscczzjj.top作为redirect_uri，而不能用http://sscczzjj.top/1作为uri（即使你将他们都添加到回调uri中）

10、只能填一个授权回调地址
回答：很抱歉，我没研究出来这个问题如何解决，所以我干脆就只写一个，嘿嘿嘿。

11、授权回调地址要填参数吗
回答：不要填，也不需要，百度不会管这个回调地址后面的参数，他只关心地址
