发现一个比curl更好的方式进行post ``` $url = 'URL'; $data = array('field1' => 'value', 'field2' => 'value'); $options = array( 'http' => array( 'header' => "Content-type: application/x-www-form-urlencoded\r\n", 'method' => 'POST', 'content' => http_build_query($data), ) ); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); var_dump($result); curl版 $url = 'http://www.someurl.com'; $myvars = 'myvar1=' . $myvar1 . '&myvar2=' . $myvar2; $ch = curl_init( $url ); curl_setopt( $ch, CURLOPT_POST, 1); curl_setopt( $ch, CURLOPT_POSTFIELDS, $myvars); curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt( $ch, CURLOPT_HEADER, 0); curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1); $response = curl_exec( $ch ); ``` 来源：http://stackoverflow.com/questions/3080146/post-data-to-a-url-in-php post json数据 ``` function http_post_data($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(); ob_end_clean(); $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); return array($return_code, $return_content); } ```
