说明:目前是通过授权获取访问者微信头像地址,并保存在数据库中,前台使用时则通过地址显示。
虽然访问者每次访问主页都会尝试更新昵称与头像地址,但在访问者修改头像直至再次访问主页时,其头像无法显示。
希望能将其微信头像保存至数据库,直接调用,避免以上情况发生。
微信头像在浏览器中能顺利打开,但无论是通过 curl 还是 get_file_contents() 都无法正常获取。
回复讨论(解决方案)
做过手机端微信和微博登陆接口
他们提供的图片地址是可以file_get_contents()的
然后直接file_put_content()保存在本地文件夹,至于路径和命名规则自己定
保存远程图片应该封装一个函数
然后把本地路径保存在服务器上
function put_file_from_url_content($url, $saveName, $path) {
// 设置运行时间为无限制
set_time_limit ( 0 );
$url = trim ( $url );
$curl = curl_init ();
// 设置你需要抓取的URL
curl_setopt ( $curl, CURLOPT_URL, $url );
// 设置header
curl_setopt ( $curl, CURLOPT_HEADER, 1 );
// 设置cURL 参数,要求结果保存到字符串中还是输出到屏幕上。
curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 );
// 运行cURL,请求网页
$file = curl_exec ( $curl );
// 关闭URL请求
curl_close ( $curl );
// 将文件写入获得的数据
$filename = $path . $saveName;
$write = @fopen ( $filename, "w" );
if ($write == false) {
return false;
}
if (fwrite ( $write, $file ) == false) {
return false;
}
if (fclose ( $write ) == false) {
return false;
}
}
put_file_from_url_content($userAvatar, $userOpenId.".jpg", $avatarPath);

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.
