How to write an interface for phpcms api

How to write an interface for phpcms api?

I recently developed a CRM system by myself. I was thinking that if it can be sold in the future, I can dynamically call the recommended information of my website through the interface. It can be regarded as a kind of advertising! So I tried to use phpcms to develop a simple api interface

phpcms v9 develops a simple api interface (for novices!)

The api interfaces of phpcms v9 are all stored in api folder, the access path is http://www.XXX.com/api.php?op=count&...., the other op=count are your specific api files, so I started based on this rule Develop!

(1) Step 1: Create the file demo.php in the api folder of the website, code:

<?php
defined(&#39;IN_PHPCMS&#39;) or exit(&#39;No permission resources.&#39;);
if($_GET[&#39;catid&#39;] && $_GET[&#39;num&#39;]) {
$catid = intval($_GET[&#39;catid&#39;]); //用来接收请求的栏目id
$num = intval($_GET[&#39;num&#39;]); //用来接收获取数量
}
$modelid =1; //设置你要调用栏目的模型id
$db = pc_base::load_model(&#39;content_model&#39;);//引入content模型
$db->set_model($modelid); //设置模型id，如果是其他非文章模型可以不需要设置这个
$arr = $db->select(array(&#39;catid&#39; => $catid),&#39;*&#39;,$num); /调用所请求栏目id下的文章
$r = json_encode($arr); //转换为json类型
//jsonp请求的固定写法，可以解决跨域问题，引入callback回调函数
echo $_GET[&#39;jsoncallback&#39;] . "(".$r.")";
?>

(2) Use ajax to send the request on the requesting page

<script>
$(function(){
$.ajax({
url:&#39;http://www.XXX.com/api.php?op=demo&catid=28&num=10&#39;,
dataType:&#39;jsonp&#39;, //jsonp类型
jsonp:"jsoncallback", //回调
type:&#39;get&#39;,
success:function(data){
var data=eval(data); //转化为json对象
$.each(data, function(index, p){
html = "<li>";
html += "<a href=&#39;"+ p.url +"&#39; target=&#39;_blank&#39;>"+ p.title +"</a>";
html += "</li>";
$("#test").append(html); //追加到id=test的div里边
})
},
error : function() {
console.log(&#39;fail&#39;);
}
});
});
</script>

ok Done! In this way, you can call things in your own website across domains!
