php post json参数的传递和接收处理方法


            页面1 ，php传递json参数的页面：

1.php





<? 

function http_post_data($url, $data_string) { 

 

  $ch = curl_init(); 

  curl_setopt($ch, CURLOPT_POST, 1); 

  curl_setopt($ch, CURLOPT_URL, $url); 

  curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); 

  curl_setopt($ch, CURLOPT_HTTPHEADER, array( 

   'Content-Type: application/json; charset=utf-8', 

   'Content-Length: ' . strlen($data_string)) 

  ); 

  ob_start(); 

  curl_exec($ch); 

  $return_content = ob_get_contents(); 

  //echo $return_content."<br>"; 

  ob_end_clean(); 

 

  $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); 

  // return array($return_code, $return_content); 

  return $return_content; 

 } 

 

$url = "http://127.0.0.1/2.php"; 

$data = json_encode(array('a'=>"weqweqwe", 'b'=>2));  

 

//list($return_code, $return_content) = http_post_data($url, $data); 

$aaa = http_post_data($url, $data); 

//print_r($aaa); 

echo $aaa; 

 

$ccc=json_decode($aaa); 

print_r($ccc); 

echo $ccc->b; 

 

echo "<hr>"; 

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; 

var_dump(json_decode($json,true)); 

　 

?> 



页面2，参数接收处理：

2.php





<? 

$postData = file_get_contents('php://input'); 

echo $postData; 

$data = json_encode(array('a'=>" 234 ", 'b'=>2)); 

echo $data; 

?>
