post | 如何自己写一个博客计数器 |
|
都怪LeanCloud,我得自己写计数器了!
事件起因
我之前用的博客计数器是用的LeanCloud作为后台制作的计数器,然后嘛……代码是抄的。结果最近LeanCloud凉了,这让我无法忍受,之前的代码我也看不懂,改也不会改……
那好吧,我只好自己写计数器了。
于是我花了很长时间,自己写了一个计数器,另外还得把原来的计数器信息转移过来……
使用方法
前端部分
主页显示点击数:
{% raw %}Hits: <span id="{{ post.url }}" class="visitors-index" >Loading...</span>{% endraw %}
内页显示点击数:
{% raw %} Hits: <span id="{{ page.url }}" class="visitors" >Loading...</span>{% endraw %}
JS代码:(需要Jquery)
var auxiliaryHost = "你的域名";
function showHitS(hits){
$.get(auxiliaryHost+"/counter.php?action=show&id="+hits.id,function(data){
hits.innerHTML=Number(data);
});
}
function showHitCount() {
var visitors=$(".visitors-index");
for(var i = 0; i < visitors.length; i++){
showHitS(visitors[i]);
}
}
function addCount() {
var visitors=$(".visitors");
$.get(auxiliaryHost+"/counter.php?action=add&id="+visitors[0].id,function(data){
visitors[0].innerHTML=Number(data);
});
}
if ($('.visitors').length == 1) {
addCount();
} else if ($('.visitors-index').length > 0){
showHitCount();
}

后端部分
MySQL建表:
CREATE TABLE `counter` (
`url` char(50) NOT NULL,
`counter` int(11) NOT NULL,
UNIQUE KEY `url` (`url`)
);
PHP:
<?php
header('Access-Control-Allow-Origin: *');
$con=mysqli_connect("MySQL地址","用户名","密码","数据库名");
if (mysqli_connect_errno($con))
{
die("连接 MySQL 失败: " . mysqli_connect_error());
}
$hid = md5($_GET['id']);
if ( $_GET['action'] == "show" ) {
$sql = "SELECT * FROM `counter` WHERE `url` = '".$hid."' ";
$result = $con->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
echo $row["counter"];
}
} else {
$sql = "INSERT INTO `counter` (`url`, `counter`)
VALUES ('".$hid."', '0')";
if ($con->query($sql) === TRUE) {
echo "0";
}else{
echo "Error";
}
}
} elseif ( $_GET['action'] == "add" ) {
$sql = "SELECT * FROM `counter` WHERE `url` = '".$hid."' ";
$result = $con->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$sql = "UPDATE `counter` SET `counter` = '".($row["counter"]+1)."' WHERE `url` = '".$hid."'";
$con->query($sql);
echo ($row["counter"]+1);
}
} else {
$sql = "INSERT INTO `counter` (`url`, `counter`)
VALUES ('".$hid."', '1')";
if ($con->query($sql) === TRUE) {
echo "1";
}else{
echo "Error";
}
}
} else {
header("HTTP/1.1 301 Moved Permanently");
header("Location: https://mabbs.github.io");
}
mysqli_close($con);
结果
看来还是自己写代码放心,至少服务是自己维护的,不像垃圾LeanCloud坏掉之后我就无能为力了……
不过说实话我根本不会JS(虽然我之前说我学这个),编写之中遇到了不少问题,所以在此感谢各位帮助我的各位大佬们,让我最终完成了这个计数器。
