php接口方式上传和接受图片base64

转化base64图片远程或本地图片,通过接口方式传输

$base_64];$headers[] = "Content-Type: application/json; charset=utf-8";$res = http_post($url,json_encode($param),false,$headers,60);var_dump($res);exit; function img_base64($path){    //对path进行判断，如果是本地文件就二进制读取并base64编码    $img_data="";    if (substr($path,0,strlen("http")) === "http"){        $img_data= n_img_base_64($path);    }else{        $img_data=  imgToBase64($path);    }    return $img_data;} function n_img_base_64($img){    $imageInfo = getimagesize($img);    return 'data:' . $imageInfo['mime'] .

接受图片base64并保存图片

PHP$data=file_get_contents("php://input");$result=JSON_decode($data,true);$res=saveBase64Image($result['img'],'test');echo  json_encode($res);function saveBase64Image($base64_image_content,$fileName){    if (preg_match('/^(data:\s*image\/(\w+);base64,)/', $base64_image_content, $result)) {        //图片后缀        $type = $result[2];        if ($type == 'jpeg') {            $type = 'jpg';        }        //保存位置--图片名        $image_name = $fileName . '-' . date('Ymd') . date('His') . '-' . str_pad(mt_rand(1, 99999), 5, '0', STR_PAD_LEFT) . "." . $type;        $Absolute_Path = $_SERVER['SCRIPT_FILENAME'];        $Absolute_Path = substr($Absolute_Path, 0, -9);        $root = $_SERVER['DOCUMENT_ROOT'];        $image_url1 = $root.'/img/'.date('Ymd');        $image_url =$image_url1.'/'.$image_name;        $httpHost = $image_url1;        if(!is_dir(dirname($image_url1))){            if (!file_exists($image_url1)) {                mkdir($image_url1, 0777, true);            }        }        //解码        $decode = base64_decode(str_replace($result[1], '', $base64_image_content));        if (file_put_contents($image_url, $decode)) {            $data['code'] = '0';            $data['imageName'] = $image_name;            $data['image_url'] = $httpHost;            $data['type'] = $type;            $data['msg'] = '保存成功！';        } else {            $data['code'] = '1';            $data['imgageName'] = '';            $data['image_url'] = '';            $data['type'] = '';            $data['msg'] = '图片保存失败！';        }    } else {        $data['code'] = '1';        $data['imgageName'] = '';        $data['image_url'] = '';        $data['type'] = '';        $data['msg'] = 'base64图片格式有误！';    }    return $data;}
