可以自己从开奖数据网站上抓取，然后自己制作接口，php代码如下：

$url = "https://kaijiang.aicai.com/cqssc/";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
//curl_setopt($ch, CURLOPT_GET, 1);
$result = curl_exec($ch);
$result = mb_convert_encoding($result, 'utf-8', 'GBK,UTF-8,ASCII');
curl_close($ch);

preg_match('/<div class=\"kj_ball lot_i\">[\s\S]*?<\/div>/',$result,$matchResult);

$matchResultHandled = str_replace('<','',$matchResult[0]);
$matchResultHandled = str_replace('>','',$matchResultHandled);
$matchResultHandled = str_replace('"','',$matchResultHandled);
$matchResultHandled = str_replace('div','',$matchResultHandled);
$matchResultHandled = str_replace('kj_ball lot_i','',$matchResultHandled);
$matchResultHandled = str_replace('class=','',$matchResultHandled);
$matchResultHandled = str_replace('i','',$matchResultHandled);
$matchResultHandled = str_replace('/','',$matchResultHandled);

echo $matchResultHandled;

如果以上代码跑不起来，可以打开php.ini 把关于curl和ssl的组件打开。
