PHP 之上传网络图片到微信临时素材

一、简单代码

$fileImage = 'https://域名/202109/11/134923278422.png';
$imgPathInfo =pathinfo($fileImage);
$basename = $imgPathInfo['filename'].'png';
$filename = dirname(__FILE__) . '/cache/image/' . $basename;
//将网络图片保存到本地
file_put_contents($filename, file_get_contents($fileImage));

//判断是否支持curl_file_create函数
if (!function_exists('curl_file_create')) {
    function curl_file_create($filename, $mimetype = '', $postname = '')
    {
        return "@$filename;filename="
            . ($postname ?: basename($filename))
            . ($mimetype ? ";type=$mimetype" : '');
    }
}
$access_token = getAccessToken($company_info['corpId'], $company_info['secret']);
$url = "https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token=$access_token&type=image";
$ch = curl_init();
$minetype = 'image/png';
$curl_file = curl_file_create($filename, $minetype);
$postData = [
    'media' => $curl_file,
];
curl_setopt($ch, CURLOPT_URL, $url);
//curl结果不直接输出
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//发送post 请求
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
//允许 cURL 函数执行的最长秒数
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
//不输出header 头信息
curl_setopt($ch, CURLOPT_HEADER, 0);
//不验证证书 信任任何证书
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// 检查证书中是否设置域名,0不验证 0：不检查通用名称（CN）属性 1：检查通用名称属性是否存在  2：检查通用名称是否存在，是否与服务器的主机名称匹配
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
@curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$res = curl_exec($ch);
curl_close($ch);
@unlink($filename);
$upload_result = json_decode($res, true);
die($upload_result['media_id']);
