搞curl上传图片，需要用到字节流上传，就是用file_get_content转成base64还是不行，参考下边的方法可以搞定

/**

     * 上传图文消息内的图片获取URL

     *

     */

    public function uploadImg(Request $request) {

        $data = [

            'media'=>'@C:\Users\shuxiaoyuan\Pictures\22222.jpg', // PHP 5.5 之前用法

            'media' =>new \CURLFile(realpath('C:\Users\shuxiaoyuan\Pictures\22222.jpg')) // PHP 5.5 之后用法

        ];

        return $this->wechat->uploadimg($data);

    }

    /**

     * 上传图文消息内的图片获取URL

     * @param array $data  PHP 5.5 之前采用 @ 符号来表示上传资源, PHP 5.5 之后采用 new \CURLFile(realpath('222.jpg'))

     * @param type 类型：图片:image 语音:voice 视频:video 缩略图:thumb

     * @return string

     *

     */

    public function uploadimg($data) {

        $url = self::API_URL_PREFIX . '/media/uploadimg?access_token=' . $this->AccessToken;

//        $url .= '&type=image';

        return $this->httpPost($url, $data, true);

    }

    /**

     * POST 请求

     *

     * @param string $url

     * @param array $param

     * @param boolean $post_file 是否文件上传

     * @return string content

     */

    private function httpPost($url, $param, $post_file = false) {

        $oCurl = curl_init();

        if (stripos($url, "https://") !== FALSE) {

            curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, FALSE);

            curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, false);

            curl_setopt($oCurl, CURLOPT_SSLVERSION, 1); //CURL_SSLVERSION_TLSv1

        }

        if (is_string($param) || $post_file) {

            $strPOST = $param;

        } else {

            $aPOST = array();

            foreach ($param as $key => $val) {

                $aPOST[] = $key . "=" . urlencode($val);

            }

            $strPOST = join("&", $aPOST);

        }

        curl_setopt($oCurl, CURLOPT_URL, $url);

        curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1);

        curl_setopt($oCurl, CURLOPT_POST, true);

        curl_setopt($oCurl, CURLOPT_POSTFIELDS, $strPOST);

        curl_setopt($oCurl, CURLOPT_TIMEOUT, 10);

        $sContent = curl_exec($oCurl);

        $aStatus = curl_getinfo($oCurl);

        curl_close($oCurl);

        if (intval($aStatus["http_code"]) == 200) {

            return $sContent;

        } else {

            return false;

        }

    }

我自己的实际用法：

$imgurl = dirname(__FILE__)."/images/123.jpg";

$data = array(

    'material_file' => new \CURLFile(realpath($imgurl)),

);

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $uploadUrl);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$res = curl_exec($ch);

curl_close($ch);
