php - 本地调用豆瓣API

Question

调用豆瓣的API，报错
XMLHttpRequest cannot load https://api.douban.com/v2/book/search?q=%E7%94%B5%E6%9C%BA%E5%AD%A6&count=10. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://mytest' is therefore not allowed access.
刚开始学PHP，求大腿帮忙解决

页面

<input type="text">
<button id="go">搜索</button>
<hr />
<p id="showbook"></p>

js

$('#go').click(function(){
        if($('input').val()==''){
            alert("请输入关键词");
        }else{
            var sq=$('input').val();
            $.ajax({
                type:"GET",
                url:"https://api.douban.com/v2/book/search",
                dataType:"json",
                data:{
                    q:sq,
                    count:10
                },
                success:function(data){
                    $.each(data.books, function(i,book) {
                        $("#showbook").append("<p><img src='" +book.image+ "' /></p>");
                    });
                },
            });
        }
        
    });

刚才我搜了一下没事ajax跨域问题，具体现在我想到的就是用jsonp格式，然后在server端加上
header("Access-Control-Allow-Origin: *"); # 跨域处理
