//网站路径
'web_path' => '/网站所在的路径/'

If The website is installed in the root directory (such as virtual host www, public_html, htdocs and other directories), then it should be set to: 'web_path' => '/'; if it is installed in the directory /blog/, Then it should be set to: 'web_path' => '/blog/' .

Method 3: Check the encoding format of the configuration file

Mainly check whether the file encoding of cache/configs/system.php and api/checkcode.php is consistent, for example, the program version is utf -8 version, then select utf-8 encoding format when saving.

When modifying these files, it is recommended to use professional text editors such as editplus, EmEditor, Sublime Text, etc. to avoid using text as the default text editor.
