保存访问者微信头像至服务器
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);

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.
