最近做一個有關微信授權登入的專案,關於授權就不多說了,我獲取到使用者基本資訊,格式如下:
$user_info = `{"openid":"xx","nickname":"nice花椒.","sex":2,"language":"zh_CN","city":"杭州","province":"浙江","country":"中國","headimgurl":"http://wx.qlogo.cn/mmopen/vi_32/Q0j4TwGTfTJPpziaqOoIpGia9ZVj9fheAwLmTiavV4rxR40NQ1zPQPyiaMY58FEISDIfpn0q5VeeXliaKyiaiabgK2ZHg/0","privilege":[]}`;
直接把headimgurl入庫儲存,bug來了。
話不多說,進入正題:
微信返回的是json格式
$user_arr = json_decode($user_info, true);
獲取使用者openid對比資料庫,判斷是不是首次授權
$mem_info= $member->getuserinfo(array(`openid`=>$user_arr[`openid`]));
首次授權或者頭像連結地址與上次不同
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`]);
}
//快來寫你的註冊或者修改程式碼吧!
}
儲存圖片
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 $new_file;
}
}
return false;
}
指定位置建立檔案
function create($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);
}
}
}
}
哈哈,我是一個專注介面的小菜鳥,多多指教!
