URL 解析器


What is a URL Parser?

A URL (Uniform Resource Locator) has a well-defined structure with multiple components: protocol/scheme (https://), username and password (for authenticated URLs), hostname (example.com), port (:8080), path (/blog/article), query string (?id=123&page=2), and fragment (#section). Parsing a URL breaks it apart into these components, making it easy to inspect, modify, or debug. This is useful when debugging API requests, understanding redirect chains, inspecting tracking URLs, or when you need to programmatically extract parts of a URL.

How to Use the URL Parser

  1. Paste any URL into the input field.

  2. The tool parses and displays each component: protocol, host, port, path, query parameters, and fragment.

  3. Query parameters are shown both as a list of key-value pairs and as formatted JSON.

  4. Copy individual components as needed.

This URL parser runs entirely in your browser using the built-in URL API — no data is sent to any server. Handles all URL formats including URLs with authentication, non-standard ports, IPv6 addresses, and complex query strings. Useful for API debugging, security analysis, and URL construction.

常见问题

在这里解码敏感数据是否安全? 是的。所有解码都在您的浏览器中使用JavaScript进行。没有数据被传输到任何服务器,因此您的编码字符串完全保持私密。

Base64和URL安全Base64之间的区别是什么? 标准Base64使用+和/字符,这些是URL中的特殊字符。URL安全Base64将其替换为-和_,这样字符串可以在URL和文件名中安全使用,无需进行百分比编码。

为什么我解码的输出看起来像乱码? 如果原始数据是二进制文件(如图像、PDF或压缩文件),解码的输出将不是可读文本。在这种情况下,Base64字符串代表二进制文件,而不是文本字符串。

Base64是一种加密形式吗? 不是。Base64是编码方案,不是加密。任何人都可以在没有密钥的情况下解码Base64字符串。它不应该用于保护敏感数据——应使用适当的加密。
