如题,PHP如何自动识别第三方Restful API的内容,自动渲染成 json、xml、html、serialize、csv、php等数据?
其实这也不难,因为Rest API也是基于http协议的,只要我们按照协议走,就能做到自动化识别 API 的内容,方法如下:
1、API服务端要返回明确的 http Content-Type头信息,如:
Content-Type: application/json; charset=utf-8 Content-Type: application/xml; charset=utf-8 Content-Type: text/html; charset=utf-8
2、PHP端(客户端)接收到上述头信息后,再酌情自动化处理,参考代码如下:
'xml', 'text/xml' => 'xml', 'application/json' => 'json', 'text/json' => 'json', 'text/csv' => 'csv', 'application/csv' => 'csv', 'application/vnd.php.serialized' => 'serialize' ); if (strpos($contentType, ';')) { list($contentType) = explode(';', $contentType); } $contentType = trim($contentType); if (array_key_exists($contentType, $autoDetectFormats)) { echo '_' . $autoDetectFormats[$contentType]($response); } //+++++++++++++++++++++++++++++++++++++++++++++++++++++++ // 常用 格式化 方法 //+++++++++++++++++++++++++++++++++++++++++++++++++++++++ /** * 格式化xml输出 */ function _xml($string) { return $string ? (array)simplexml_load_string($string, 'SimpleXMLElement', LIBXML_NOCDATA) : array(); } /** * 格式化csv输出 */ function _csv($string) { $data = array(); $rows = explode("\n", trim($string)); $headings = explode(',', array_shift($rows)); foreach( $rows as $row ) { // 利用 substr 去掉 开始 与 结尾 的 " $data_fields = explode('","', trim(substr($row, 1, -1))); if (count($data_fields) === count($headings)) { $data[] = array_combine($headings, $data_fields); } } return $data; } /** * 格式化json输出 */ function _json($string) { return json_decode(trim($string), true); } /** * 反序列化输出 */ function _serialize($string) { return unserialize(trim($string)); } /** * 执行PHP脚本输出 */ function _php($string) { $string = trim($string); $populated = array(); eval("\$populated = \"$string\";"); return $populated; }
