🇨🇳中文介绍

网络调试

概述

网络调试用于识别影响应用程序性能的连接问题、延迟问题和数据传输错误。

使用时机

加载时间缓慢
请求失败
间歇性连接
CORS 错误
SSL/TLS 问题
API 通信问题

快速开始

最小工作示例：

Chrome DevTools Network Tab:

Columns:
  - Name: Request file/endpoint
  - Status: HTTP status code
  - Type: Resource type (xhr, fetch, etc)
  - Initiator: What triggered request
  - Size: Resource size / transferred size
  - Time: Total time to complete
  - Waterfall: Timeline visualization

Timeline Breakdown:
  - Queueing: Waiting in queue
  - DNS: Domain name resolution
  - Initial connection: TCP handshake
  - SSL: SSL/TLS negotiation
  - Request sent: Time to send request
  - Waiting (TTFB): Time to first byte
  - Content Download: Receiving response

---
Network Conditions:

Throttling Presets:
  - Fast 3G: 1.6 Mbps down, 750 Kbps up
// ... (see reference guides for full implementation)

Failed requests
Intermittent connectivity
CORS errors
SSL/TLS issues
API communication problems
