此工具的功能
OAuth 回调 URL；强调 localhost 需公网 HTTPS。
The Query Param Quchong helps you work faster during local API and webhook development. Paste input directly into the panel above and get immediate feedback without installing desktop software or sending secrets to a remote server.
开发者何时使用
OAuth 回调 URL；强调 localhost 需公网 HTTPS。
Reach for this tool when debugging webhook payloads, validating headers, formatting JSON, or preparing HTTP snippets before you wire up a tunnel for live provider callbacks. It is especially useful when staging is unavailable or too slow for quick iteration.
浏览器内操作步骤
OAuth 回调 URL；强调 localhost 需公网 HTTPS。
Open the tool panel and paste your payload, URL, headers, or token material. Review formatted output, validation messages, or generated snippets. Copy results into your app, tests, or API client. When a provider requires a public HTTPS URL, run npx portpreview 3000 and register the tunnel URL.
输入/输出示例

Start with realistic webhook or API samples from your provider docs. The query param quchong highlights syntax errors, missing fields, and encoding issues so you can fix problems before events hit your local server.
常见错误与修复
OAuth 回调 URL；强调 localhost 需公网 HTTPS。
Wrong encoding: ensure raw body vs parsed JSON matches what your signature verifier expects. Missing headers: webhook providers often require specific header names — compare against official docs. Localhost-only URLs: external services cannot call 127.0.0.1 ; use an HTTPS tunnel for delivery tests.
安全与隐私（客户端处理）

Processing happens in your browser tab. PortPreview does not store pasted secrets unless you separately use tunnel or account features. Avoid pasting production credentials; use test-mode keys and rotate anything accidentally exposed.
