原生PHP接收$_POST的几种方式

Posted 2021-01-28

• > HTTP 常见 Content-Type

  > application/x-www-form-urlencoded
  > multipart/form-data
  > application/json

• > $_POST 默认只能接收到 Content-Type: application/x-www-form-urlencoded 的数据

• > 如果Content-Type: application/json 需要用到php://input 处理输入流

  > 请求内容 {"account": "123456"}
  > $tmpData = strval(file_get_contents("php://input"));
  > $DataArray = json_decode($tmpData, true);
  > $account = $DataArray[‘account‘];

• > Content-Type: multipart/form-data

  > $tmpData = strval(file_get_contents("php://input"));
  > public function parseData($data) {
  > $list = explode(" ", $data);
  > foreach($list as $value) {
  > if($value) {
  > if(strstr($value, ‘--‘)) continue;
  > if(strpos($value, ‘-‘)) {
  > $key = str_replace(‘"‘, ‘‘, strchr($value, ‘"‘));
  > continue;
  > };
  > if($value) {
  > $array[$key] = $value;
  > }
  > }
  > }
  > return $array;
  > }
  > $DataArray = $this->parseData($tmpData);
  > $DataArray[‘account‘];
