如何用PHP获取无字段的json数据
1、如何用PHP获取json数据?
解决这个问题,通常的解决方式是这样的:
$jsonData = $_POST[‘jsonstr’];
此方式需要客户端提交一个jsonstr的参数过来,里面含的数据是json字符串,然后在服务端解析。
2、客户端直接传json数据过来
如果客户端直接传json数据过来,而没有上述jsonstr的参数。使用$_GET,$_POST 和 $_REQUEST是获取不到数据的。
解决的办法就是使用使用$GLOBALS这个全局变量,$GLOBALS[‘HTTP_RAW_POST_DATA’]就能获取客户端传来的json数据了。
下面给出Thinkphp中控制器的使用curl提交数据代码:
class CcAction extends Action { public function getjson(){ echo json_encode($GLOBALS['HTTP_RAW_POST_DATA']);//这里就能获取到testcurl传来的$json_string } public function testcurl(){ $header = array('Accept:application/json', 'Content-Type:application/json'); $patoken = array( 'name' => 'phpjyz', 'age' => '23', ); $json_string = json_encode($patoken); $ch = curl_init(); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_USERAGENT, 'SSTS Browser/1.0'); curl_setopt($ch, CURLOPT_ENCODING, 'gzip'); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1); curl_setopt($ch, CURLOPT_URL, 'http://www.scutephp.com/api.php/cc/getjson'); curl_setopt($ch, CURLOPT_POSTFIELDS, $json_string); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); $ret = curl_exec($ch); print_r(json_decode($ret, true)); } }
返回的数据和$json_string是一模一样的。

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.
