现在大部分获取昵称的接口都是用的QQ空间的，至于邮箱，直接在QQ号后面加上@qq.com就行了，今天分享一个WordPress网站评论时自动填写QQ邮箱与昵称教程。
先把下面的接口保存为PHP文件，放在你的网站中，确保能被访问，之所以写成接口是为了避免跨域请求。
<?php
header(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”content-Type:application/json; charset=utf-8\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”);
$type = @$_GET[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’type\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] ? $_GET[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’type\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] : \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;
if(empty($type)){
exit;
}
if($type == \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”getqqnickname\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”){
$qq = isset($_GET[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’qq\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’]) ? addslashes(trim($_GET[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’qq\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’])) : \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;
if(!empty($qq) && is_numeric($qq) && strlen($qq) > 4 && strlen($qq) < 13){
$qqnickname = file_get_contents(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’http://users.qzone.qq.com/fcg-bin/cgi_get_portrait.fcg?uins=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.$qq);
if($qqnickname){
$qqnickname = mb_convert_encoding($qqnickname, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”UTF-8\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”GBK\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”);
$str=explode(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”,$qqnickname);
$s=str_replace(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, $str[6]);
print_r(json_encode(array(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”nicek\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”=>$s)));
}
}
}
if($type == \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”getqqavatar\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”){
$qq = isset($_GET[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’qq\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’]) ? addslashes(trim($_GET[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’qq\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’])) : \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;
if(!empty($qq) && is_numeric($qq) && strlen($qq) > 4 && strlen($qq) < 13){
$qqavatar = file_get_contents(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’http://ptlogin2.qq.com/getface?appid=1006102&imgtype=3&uin=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.$qq);
if($qqavatar){
$str= str_replace(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”pt.setHeader\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”qqavatarCallBack\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”,$qqavatar);
echo substr($str,17,strlen($str)-18);
}
}
}
上面的接口中我只取了昵称这个数据，如果你需要头像链接也可以取出来，至于怎么取数据我就不多说了，方法多种多样，看自己喜好。需要注意的是头像也是QQ空间的头像。当然你也可以通过后面的接口取头像，这个就是QQ的头像。
然后在你的主题全局加载的js中写上下面的js代码。注意jquery选择器选择的HTML标签，根据你自己的改一下。
$(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”#comt-qq\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”).blur(function() {
var curValue = $(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”#comt-qq\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”).val();
if ($.trim(curValue) == \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”) {
//空值
} else {
$(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”#email\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”).val(curValue + \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”@qq.com\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”);
getQQnic(curValue);
}
});
function getQQnic(num) {
$.get(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”你的接口文件地址（就是上面的代码保存的文件）.php?type=getqqnickname&qq=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” + num, function(data) {
$(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”#author\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”).val(data.nicek);
});
}
只要没有语法问题，应该就可以看到效果了，填完QQ号之后，点击其它区域，取消掉输入QQ号的编辑框的焦点就会自动查询并填写相关资料。有的人需要把QQ号也存到评论信息里，不知道想干嘛，完全没有意义。当然要实现也很简单，使用wordpress的函数给评论增加一个字段，然后在评论提交处将评论数据中传来的QQ号一起提交就好了。
