本文实例讲述了PHP7基于curl实现的上传图片功能。分享给大家供大家参考,具体如下:
根据php版本不同,curl模拟表单上传的方法不同
php5.5之前
1 2 3 4 5 6 7 8 9 10 11 12 | $curl = curl_init(); if (defined( 'CURLOPT_SAFE_UPLOAD' )) { curl_setopt( $curl , CURLOPT_SAFE_UPLOAD, false); } curl_setopt( $curl , CURLOPT_URL, $url ); curl_setopt( $curl , CURLOPT_POST, 1 ); curl_setopt( $curl , CURLOPT_POSTFIELDS, $data ); curl_setopt( $curl , CURLOPT_RETURNTRANSFER, 1); curl_setopt( $curl , CURLOPT_USERAGENT, "TEST" ); $result = curl_exec( $curl ); $error = curl_error( $curl ); |
php5.5之后,到php7
1 2 3 4 5 6 7 8 9 10 | $curl = curl_init(); curl_setopt( $curl , CURLOPT_SAFE_UPLOAD, true); $data = array ( 'file' => new \CURLFile( realpath ( $path ))); url_setopt( $curl , CURLOPT_URL, $url ); curl_setopt( $curl , CURLOPT_POST, 1 ); curl_setopt( $curl , CURLOPT_POSTFIELDS, $data ); curl_setopt( $curl , CURLOPT_RETURNTRANSFER, 1); curl_setopt( $curl , CURLOPT_USERAGENT, "TEST" ); $result = curl_exec( $curl ); $error = curl_error( $curl ); |
下面提供一个兼容的方法:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | $curl = curl_init(); if ( class_exists ( '\CURLFile' )) { curl_setopt( $curl , CURLOPT_SAFE_UPLOAD, true); $data = array ( 'file' => new \CURLFile( realpath ( $path ))); //>=5.5 } else { if (defined( 'CURLOPT_SAFE_UPLOAD' )) { curl_setopt( $curl , CURLOPT_SAFE_UPLOAD, false); } $data = array ( 'file' => '@' . realpath ( $path )); //<=5.5 } curl_setopt( $curl , CURLOPT_URL, $url ); curl_setopt( $curl , CURLOPT_POST, 1 ); curl_setopt( $curl , CURLOPT_POSTFIELDS, $data ); curl_setopt( $curl , CURLOPT_RETURNTRANSFER, 1); curl_setopt( $curl , CURLOPT_USERAGENT, "TEST" ); $result = curl_exec( $curl ); $error = curl_error( $curl ); |
其中:
$path:为待上传的图片地址
$url:目标服务器地址
例如
1 2 | $path = "/bg_right.jpg" |
upload.php示例:
1 2 3 4 5 6 | <?php file_put_contents (time(). ".json" , json_encode( $_FILES )); $tmp_name = $_FILES [ 'file' ][ 'tmp_name' ]; $name = $_FILES [ 'file' ][ 'name' ]; move_uploaded_file( $tmp_name , 'audit/' . $name ); ?> |
PHP7.0演示示例
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | /**xm编写php7.0模拟fomadata文件上传 * @param $url * @param $arr */ function curl_post_file($url,$arr){ $curl = curl_init(); curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true ); //$data = array('media' => new \CURLFile(realpath($p))); $data=$arr; curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_POST, 1 ); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_USERAGENT, "TEST" ); $result = curl_exec($curl); $error = curl_error($curl); return $result; } |

1 2 3 4 | $url = "https://api.weixin.qq.com/wxa/img_sec_check?access_token=" .$token; $p=str_replace( "\\" , "/" ,ROOT_PATH. "public" .$pic); //图片路径 $data = array( 'media' => new \CURLFile(realpath($p))); $mgan_json=curl_post_file($url,$data); |
