微信授权后用户头像保存到服务器实现方法

本文主要和大家分享微信授权后用户头像保存到服务器实现方法，最近做一个有关微信授权登录的项目，关于授权就不多说了，我获取到用户基本信息,格式如下：$user_info = '{"openid":"xx","nickname":"nice花椒.","sex":2,"language":"zh_CN","city":"杭州","province":"浙江","country":"中国","headimgurl":"http://wx.qlogo.cn/mmopen/vi_32/Q0j4TwGTfTJPpziaqOoIpGia9ZVj9fheAwLmTiavV4rxR40NQ1zPQPyiaMY58FEISDIfpn0q5VeeXliaKyiaiabgK2ZHg/0","privilege":[]}';直接把headimgurl入库保存，bug来了。

话不多说，进入正题：

微信返回的是json格式$user_arr = json_decode($user_info, true);获取用户openid对比数据库，判断是不是首次授权$mem_info= $member->getuserinfo(array('openid'=>$user_arr['openid']));首次授权或者头像链接地址与上次不同if(!$mem_info || $mem_info['wximage']!=$user_info['headimg']){$headimgurl = saveheadimgurl($user_arr['headimgurl']);$headimg ? 0 : $headimg='lib/avata.jpg' ;if($mem_info['wximage']!=$user_info['headimg']){unlink($mem_info['headimg']);}//快来写你的注册或者修改代码吧！}保存图片function saveheadimgurl($headimg){$header = array('User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:45.0) Gecko/20100101 Firefox/45.0','Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3','Accept-Encoding: gzip, deflate',);$curl = curl_init();curl_setopt($curl, CURLOPT_URL, $headimg);curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);curl_setopt($curl, CURLOPT_HTTPHEADER,$header);$dataimg = curl_exec($curl);$code = curl_getinfo($curl, CURLINFO_HTTP_CODE);curl_close($curl);if ($code == 200) {$imgBase64Code = "data:image/jpeg;base64," . base64_encode($dataimg);}$img_content=$imgBase64Code;if (preg_match('/^(data:s*image/(w+);base64,)/', $img_content, $result)){$type = $result[2];create(DOFILESPATH."head");$new_file = DOFILESPATH."head/".md5(uniqid(rand())).".{$type}";if (file_put_contents($new_file, base64_decode(str_replace($result[1],'', $img_content)))){return $new_file;}}return false;}指定位置创建文件function create($dir){if(is_dir($dir)){$temp = explode('/',$dir);$cur_dir = '';for($i=0; $i<count($temp); $i++){$cur_dir .= $temp[$i].'/';if(!is_dir($cur_dir)){@mkdir($cur_dir,777);}}}}希望对大家有用。
