emlog评论添加一键获取QQ昵称和头像教程（附代码） 先放出方法一：转自http://wemcc.com/bk/43.html首先在module.php里面加以下代码：<?php //获取QQ信息 function getqqtx($qq){ $url="http://q.qlogo.cn/headimg_dl?bs=qq&amp;dst_uin=$qq&amp;src_uin=qq.feixue.me&amp;fid=blog&amp;spec=100"; return $url;} if(isset($_POST['qq'])){ $spurl = "http://r.pengyou.com/fcg-bin/cgi_get_portrait.fcg?uins={$_POST['qq']}"; $data = file_get_contents($spurl); $nc=explode('"',$data); $s=$nc[5]; $bm=mb_convert_encoding($s,'UTF-8','UTF-8,GBK,GB2312,BIG5'); if(empty($bm)){echo '<script>parent.document.getElementsByName("comname")[0].value = "QQ账号错误";parent.document.getElementsByName("commail")[0].value = "QQ账号错误";parent.document.getElementsByName("comurl")[0].value = "QQ账号错误";</script>';} else{echo '<script>parent.document.getElementsByName("comname")[0].value = "'.$bm.'";parent.document.getElementsByName("commail")[0].value = "'.$_POST['qq'].'@qq.com";parent.document.getElementsByName("comurl")[0].value = "http://user.qzone.qq.com/'.$_POST['qq'].'";parent.document.getElementById("toux").src="http://q.qlogo.cn/headimg_dl?bs=qq&amp;dst_uin='.$_POST['qq'].'&amp;src_uin=qq.feixue.me&amp;fid=blog&amp;spec=100";</script>';} } function getqqxx($qq){ $ssud=explode("@",$qq,2); if($ssud[1]=='qq.com'){ echo getqqtx($ssud[0]); }else{ echo MyGravatar($qq); }} ?>然后继续在module.php里面找到getGravatar($comment['mail'])这个替换成getqqtx($comment['mail'])一共有两个好像。反正都有的话就都换了然后在你的发表评论那些代码里加上以下代码，CSS什么的就自己写啦。这样下来就OK了。 <form action="" method="post" target="hiddenIframe"> <li> <input placeholder="选填" value="" type="text" name="qq"/> <label for="author"><i class="fa fa-qq"></i>QQ : </label> <button type="submit" id="hqziliao">获取信息</button> </li> </form>上面的代码，我没测试，但应该是可以的，dux大前端的评论就是这套代码下面放出本站，也就是我的方法：之前在别人博客看到效果，就自己想办法实现的。之前有人找我要，因为太散，今天整理一下，全部发出来，应该可以借助上面的方法优化的，但是，我懒得折腾了。直接给方法先说qq头像的获取方法：https://q1.qlogo.cn/g?b=qq&nk=" + qq + "&s=40 里面的qq换成你的qq号就是你的qq头像，后面的s是size大小昵称的获取，我是自己写了一个api：附代码：<?php header('Content-type: text/html; charset=gbk'); $id=isset($_REQUEST['id'])?$_REQUEST['id']:NULL; $url = 'http://users.qzone.qq.com/fcg-bin/cgi_get_portrait.fcg?get_nick=1&uins='.$id; $n = file_get_contents($url); $z = ',"'; $y = '",0]})'; echo getSubstr($n,$z,$y); function getSubstr($str, $leftStr, $rightStr) { $left = strpos($str, $leftStr); $right = strpos($str, $rightStr,$left); if($left < 0 or $right < $left) return ''; return substr($str, $left + strlen($leftStr), $right-$left-strlen($leftStr)); } ?>ajax发起请求传入qq应该就能拿到昵称了；现在说怎么添加到评论系统在module.php中找到发表评论部分，改造表单：<div class="tijiao" style="display: none;"> <p class="close2">评论信息框<a href="javascript:;" title="关闭"></a> <br> <?php if(ROLE == 'admin' || ROLE == 'writer'):?> 账户已登录，可直接发表评论！ <?php else:?> <span><i class="fa fa-question-circle"></i> 可使用QQ号实时获取昵称+头像</span></p> <p> <input onkeydown="if(event.keyCode==13){event.returnValue=false;}" class="tex" type="text" id="nickqq" name="comqq" maxlength="49" value="" size="22" tabindex="1" placeholder="选填"> <label id="qq" for="author"><img src="https://q1.qlogo.cn/g?b=qq&amp;nk=39784480&amp;s=40" class="emailavatar" style="display: none;"><i class="fa fa-qq" style="display: inline-block;"></i> QQ:</label> </p> <p> <input onkeydown="if(event.keyCode==13){event.returnValue=false;}" class="tex" type="text" id="nickname" name="comname" maxlength="49" value="<?php if(empty($ckname)){ echo "匿名";}else{echo $ckname;} ?>" size="22" tabindex="2" placeholder="必填"> <label for="author"><i class="fa fa-user"></i> 昵称:</label> </p> <p> <input onkeydown="if(event.keyCode==13){event.returnValue=false;}" class="tex" type="email" name="commail" id="email" maxlength="128" value="<?php echo $ckmail; ?>" size="22" tabindex="3" placeholder="选填"> <label id="email" for="email"><img src="http://blog.moxiaonai.cn/content/templates/moxiaonai/gravatar/default.jpg" class="emailavatar" style="display: none;"><i class="fa fa-envelope-square"></i> 邮箱:</label> </p> <p> <input onkeydown="if(event.keyCode==13){event.returnValue=false;}" class="tex" type="text" id="comurl" name="comurl" maxlength="128" value="<?php echo $ckurl; ?>" size="22" tabindex="4" placeholder="选填" pattern="((http|https)://|)+([\w-]+\.)+[\w-]+(/[\w- ./?%&amp;=]*)?"> <label for="url"><i class="fa fa-globe"></i> 网址:</label> </p><?php endif;?> <p> </p><div class="ajaxloading">吃奶的力气提交吐槽中...</div> <div class="error"></div> <p></p> <p> <button type="submit" id="usb" tabindex="5">发表评论</button> </p> <input type="hidden" name="pid" id="comment-pid" value="0" size="22" tabindex="1"> </div>关键就是js部分了，我封装成了两个函数：function get_emailinfo() { if ("" != jQuery("#email").val()) if ( - 1 != jQuery("#email").val().indexOf("qq.com")) { var a = jQuery("#email").val().replace("@qq.com", ""); isNum(a) ? ($("#email .emailavatar,#qq i").hide(), $("#email i,#qq .emailavatar").show(), $("#nickqq").val(a), jQuery("#qq .emailavatar").attr("src", "../content/templates/moxiaonai/images/pjax_loading.gif"), setTimeout(function() { jQuery("#qq .emailavatar").attr("src", "https://q1.qlogo.cn/g?b=qq&nk=" + a + "&s=40") }, 1E3)) : ($("#nickqq").val(""), $("#qq .emailavatar,#email i").hide(), $("#qq i,#email .emailavatar").show(), jQuery("#email .emailavatar").attr("src", "../content/templates/moxiaonai/images/pjax_loading.gif"), setTimeout(function() { jQuery("#email .emailavatar").attr("src", "http://secure.gravatar.com/avatar.php?gravatar_id=" + hex_md5(jQuery("#email").val())) + "&size=32&d=monsterid&r=G&default=http://blog.moxiaonai.cn/content/templates/moxiaonai/gravatar/default.jpg" }, 1E3)) } else "" != jQuery("#email").val() && ($("#nickqq").val(""), $("#qq .emailavatar,#email i").hide(), $("#qq i,#email .emailavatar").show(), jQuery("#email .emailavatar").attr("src", "../content/templates/moxiaonai/images/pjax_loading.gif"), setTimeout(function() { jQuery("#email .emailavatar").attr("src", "http://secure.gravatar.com/avatar.php?gravatar_id=" + hex_md5(jQuery("#email").val())) + "&size=32&d=identicon&r=G&default=http://blog.moxiaonai.cn/content/templates/moxiaonai/gravatar/default.jpg" }, 1E3)); else $("#email i").show(), $("#email .emailavatar").hide() } function get_qqinfo() { if ("" != jQuery("#nickqq").val()) { var a = jQuery("#nickqq").val(); isNum(a) ? ($("#qq i,#email .emailavatar").hide(), $("#qq .emailavatar,#email i").show(), jQuery("#qq .emailavatar").attr("src", "../content/templates/moxiaonai/images/pjax_loading.gif"), $("#usb").attr("disabled", "disabled"), $("#nickname").val("昵称获取中..."), $.ajax({ type: "GET", url: "/content/templates/moxiaonai/api/getqq_info.php?id=" + a, data: "", cache: !1, dataType: "html", success: function(b) { "" != b ? $("#nickname").val(b) : $("#nickname").val("匿名"); $("#usb").removeAttr("disabled") }, error: function(b, a, d) { $("#nickname").val("昵称获取失败"); $("#usb").removeAttr("disabled") } }), setTimeout(function() { jQuery("#qq .emailavatar").attr("src", "https://q1.qlogo.cn/g?b=qq&nk=" + a + "&s=40") }, 1E3), $("#email").val(a + "@qq.com"), $("#comurl").val("http://user.qzone.qq.com/" + a)) : ($("#email .emailavatar,#qq .emailavatar").hide(), $("#email i,#qq .i").show(), $("#nickqq").val("")) } else $("#qq i").show(), $("#qq .emailavatar").hide() } function isNum(a) { return /^[0-9]+$/.test(a) }上面的方法评论列表每次访问都会重新获取昵称跟头像，如果有一天接口不能访问了，那么结果可想而知， 我这里的做法是把头像存储到本地：当然，我模板里是ok的，移植的同学就需要注意路径了。 贴出函数：<?php //avatar缓存 function BYSB_getGravatar($email, $s = 44, $d = 'wavatar', $r = 'g') { if (empty($email)) { return TEMPLATE_URL.'gravatar/default.jpg'; } $f = md5($email); $emailArr = explode("@",$email); $n = $emailArr[0]; if(preg_match("/^\d*$/",$n)){ $t = 1296000; if (!empty($n)|| (time() - filemtime($e)) > $t ) { $m = TEMPLATE_URL.'gravatar/qq/'.$n.'.jpg'; $p = EMLOG_ROOT.'/content/templates/moxiaonai/gravatar/qq/'.$n.'.jpg'; if (!is_file($p)) { $q = "https://q1.qlogo.cn/g?b=qq&nk=".$n."&s=100"; copy($q,$p);$m = $q; } return $m; } }else{ $a = TEMPLATE_URL.'gravatar/'.$f.'.jpg'; $e = EMLOG_ROOT.'/content/templates/moxiaonai/gravatar/'.$f.'.jpg'; $t = 1296000; if (empty($email)) $a = TEMPLATE_URL.'gravatar/default.jpg'; if (!is_file($e) || (time() - filemtime($e)) > $t ) { $g = sprintf("http://secure.gravatar.com", (hexdec($f{0})%2)).'/avatar/'.$f.'?s='.$s.'&d='.$d.'&r='.$r; copy($g,$e); $a=$g; } if (filesize($e) < 500) copy($d,$e); return $a; } }?>然后在module.php中找到getGravatar($comment['mail'])这个替换成BYSB_getGravatar($value['mail'],44)，我模板中一共有三处。               如果觉得这篇文章对您有所帮助，不如请我喝杯咖啡！ 点击捐赠
