Curl Request/signature

Signature Rules:

The first step,

Parameter name ASCII code from small to large sort (dictionary order);

When a validation call returns or proactively notifies the signature, the routed sign parameter does not participate in the signature, and the generated signature is verified with the sign Value.

Step two,

in the Stringa final stitching on App_secret get stringsigntemp string, and stringsigntemp MD5 operation, get sign

Code:

function Make_sign ($data, $Secret) {

      Ksort ($data);
$KV _arr = Array ();
      foreach ($data as $key = = $val) {
          if ($key = = "sign" | | $val = = ') {
      Continue
   }
          Array_push ($kv _arr, $key. ' = '. $val);
      }

$MD 5_string = implode (' & ', $kv _arr);
      $key _str = $md 5_string. ' &key= '. $Secret;

      return strtolower (md5 ($key _str));
  

To receive a JSON parameter request:

$req _param = Json_decode (file_get_contents (' php://input '), true);
