Chrome不直接打開本地文件是出於安全限制。現(xiàn)代瀏覽器如Chrome會阻止通過file:///路徑加載某些功能，以防止JavaScript讀寫文件、網(wǎng)頁訪問敏感數(shù)據(jù)或腳本異常運行等問題，導致出現(xiàn)“不允許加載本地資源”或空白頁面等情況。解決方法包括：1.使用本地服務(wù)器（如Python的http.server或VS Code擴展）通過http://localhost提供文件；2.將文件拖入Chrome而非通過路徑打開；3.臨時使用更寬鬆的瀏覽器如Firefox；4.以--allow-file-access-from-files標誌啟動Chrome（僅臨時使用）。該問題常見於學習HTML/CSS/JS、查看本地文檔或嵌入本地資源時。

Chrome doesn't open local files directly due to security restrictions. That's usually why when you try to access a file using the file:/// path, it either doesn't load or gives an error.

This is a common issue for people who are trying to preview HTML pages or other content stored locally on their machine. Let's break down what's going on and how to work around it.

Chrome Blocks Local File Access for Security

Modern browsers like Chrome restrict loading certain features from local files (using file:/// ) because of potential security risks. For example:

• JavaScript that tries to read or write files could be dangerous.
• Web pages might try to access sensitive data on your computer without permission.
• Extensions or scripts running in the page could act unexpectedly.

So even if you just want to view a simple HTML file, Chrome may block things like AJAX requests, local storage, or external resource loading.

If you see messages like:

• “Not allowed to load local resource”
• “Blocked by CORS policy”
• Or nothing loads at all

…it's likely due to these built-in protections.

How to Actually Open Local Files in Chrome

If you're working on web development or testing HTML/JS/CSS locally, here are some practical ways to get around the restriction:

• Use a local server
  Tools like Python's built-in HTTP server or VS Code extensions can serve your files over http://localhost , which Chrome treats as a normal website.

  For example, if you have Python installed:

   python -m http.server 8000

  Then go to http://localhost:8000 in Chrome.

• Drag-and-drop instead of opening via file path
  Sometimes dragging the file into Chrome works better than typing file:///path/to/file.html . It depends on what the file is doing under the hood.

• Use a browser that allows local file access (temporarily)
  Firefox is generally more lenient with local files, so you can test there if needed — though it's not recommended for regular browsing.

• Launch Chrome with flags (not ideal for daily use)
  You can technically disable security checks by starting Chrome with --allow-file-access-from-files , but this opens up vulnerabilities and should only be used temporarily.

When This Issue Usually Comes Up

People often run into this when:

• Learning HTML/CSS/JS and trying to preview pages
• Opening documentation or interactive tutorials saved locally
• Trying to embed local resources like images or JSON files in a webpage

It's especially confusing for beginners because double-clicking an .html file opens it in the browser — but not all features work as expected.

In short, Chrome blocks local file access for good reason, but there are easy workarounds. Running a local server is usually the cleanest solution for development purposes.

基本上就這些。
