If the directory contains the q_login-qq_login.html file, this file is displayed.

If not, run index. php? Q_login-qq_login.html

If the directory contains the q_login-qq_login.html file, this file is displayed.

If not, run index. php? Q_login-qq_login.html

The q_login-qq_login.html exists, but the browser views the code only:

You cannot find the template file. THINKPHP project.

Due to this error, my QQ quick login (QQ internet) application has been rejected!
* Q * .html is not found in the template. besides login.html, other QQ login template files that seem to be associated with the preceding URLs are not found,
But login.html is not a template file for QQ login, which is really a headache!

?? Is thinkphp's. htaccess rewrite

RewriteCond % {REQUEST_FILENAME }! -D is not a category?
RewriteCond % {REQUEST_FILENAME }! -F is not a file either.
RewriteRule ^ (. *) $ index. php? /$1 [QSA, PT, L] redirect to index. php? Management

Hmm ~ How can I find the template file so that/q_login-qq_login.html displays the correct content?

Depressing ,,,,,

Now you can go to the QQ logon page, but the error message is: redirect uri is illegal (100010)
