豆瓣ISBN图书信息API接口独立部署

宝塔机新建一个网站：

网站根目录下新建一个index.php文件。

index.php源代码：
-

<?php
//剪切
function cut($content,$start,$end) {
$r = explode($start, $content);
if (isset($r[1])) {
$r = explode($end, $r[1]);
return $r[0];
}
return '';
}
//模拟get请求
function get($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.7 (KHTML, like Gecko) Chrome/20.0.1099.0 Safari/536.7 QQBrowser/6.14.15493.201');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$isbn = @$_GET['isbn'];
$surl = 'https://book.douban.com/isbn/'.$isbn.'/';
$headers = json_encode(get_headers($surl),true);
$headers = json_encode($headers,true);
$surl  = cut($headers,'Location: ','"');
$surl  = str_replace('\\','' ,$surl);//302地址
$data = get($surl);
$data_1=cut($data,'application/ld+json">','</script>');
$data_1 = json_decode($data_1,true);
$res['name'] = $data_1['name'];//书名
- $author = $data_1['author'];
if($author[0]==''){
$author[0]['name'] = '未知';
}
$res['author'] =$author[0]['name'];//作者
$res['photoUrl'] = cut($data,'data-pic="','"');//图标
$publishing = cut($data,'出版社:</span>','<br/>');
$publishing = cut($publishing,'">','</a>');
if($publishing==''){
$publishing ='未知';

GET API接口调试：

• 在线http post,get接口测试请求工具online,在线post,在线get,在线接口测试,api在线,生成文档,生成markdown文档,utf,gbk,转码-在线工具-postjson
• {:height 820, :width 837}

注意事项

• 在获取API返回数据的过程中，通过IOS的快捷指令，发现获取URL的词典值是空的。查看返回值JOSN格式的原始Response有问题。
• 

解决方式是在index.php代码的json_encode函数上增加JSON_UNESCAPED_UNICODE和JSON_UNESCAPED_SLASHES两个参数。
