在IIS服务器部署Codeigniter项目后无法获取视频的问题咨询

Hey there, let's figure out why your videos in the assets folder aren't loading while images work fine. I've dealt with similar IIS + CodeIgniter quirks before, so here are the most common fixes to try:

1. Missing MIME Types in IIS #

IIS doesn't come pre-configured with all video format MIME types by default. If your videos are in formats like .mp4, .mov, or .avi, IIS might not recognize how to serve them. Here's how to add them:

• Open IIS Manager, navigate to your CodeIgniter site
• Double-click the MIME Types feature
• Click Add in the right-hand actions pane
• For each video format, enter the extension (e.g., .mp4) and corresponding MIME type (e.g., video/mp4)
• Save the changes and restart your site

2. CodeIgniter Rewrite Rules Blocking Static Assets #

If your .htaccess or routing config is redirecting all requests to index.php, video requests might be getting caught by CodeIgniter's router instead of being served directly. Update your .htaccess to exclude the assets folder from rewrites:

RewriteEngine On
# Exclude assets folder from CI routing
RewriteCond %{REQUEST_URI} !^/assets/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

3. Incorrect File Permissions #

Even though images load, video files might have different permission settings. Make sure the IIS application pool user has read access to your assets folder and its video files:

• Right-click the assets folder → Properties → Security tab
• Click Edit → Add
• Enter IIS_IUSRS (or your specific app pool identity, like DefaultAppPool) and click Check Names
• Grant the user Read & execute permissions, then apply the changes

4. Case Sensitivity Mismatch #

While Windows is case-insensitive, IIS can sometimes throw errors if the URL's file name doesn't exactly match the actual file's case (e.g., video.mp4 vs Video.MP4). Double-check that your video URLs use the exact same case as the files stored in assets.

5. IIS Request Filtering Blocking Video Files #

IIS might be configured to block requests for certain video file extensions. Verify this isn't the case:

• In IIS Manager, go to your site and open Request Filtering
• Switch to the File Name Extensions tab
• Look for your video extensions (e.g., .mp4) — if they're in the "Denied" list, remove them
• If they aren't listed at all, click Allow Extension and add them manually

Try these steps one by one, and odds are one of them will get your videos loading properly. Let me know if you hit any snags!
