The project lacked end-user documentation covering deployment, configuration, and common failure scenarios. Users struggle with build issues, credential configuration, ECS metadata service, and cross-platform compatibility without clear guidance.

Changes

  • Added 用户使用指南.md (1,585 lines): Complete Chinese user guide structured for rapid problem resolution

Document Structure

1. Project Overview

  • 10 credential types (AccessKey, STS, ECS RAM Role, OIDC, OAuth, etc.)
  • Default provider chain priority: env vars → OIDC → config file → ECS IMDS → URI

2. Prerequisites & Environment

  • Compiler requirements: GCC 4.9+, VS 2015+, Clang with C++11
  • Required: OpenSSL; Optional: nlohmann_json (enables JSON config format)
  • Platform-specific installation commands for all dependencies

3. Quick Start

  • 3 installation methods (Linux script, manual CMake, Windows GUI)
  • Environment variable vs config file setup (INI and JSON formats)
  • Complete code examples with compilation commands

4. FAQ (27 issues) - Core troubleshooting section organized by category:

  • Build: OpenSSL not found, Windows runtime mismatch (MT/MD), pthread linking
  • Configuration: Default chain failures, env var priority, file permissions (600)
  • ECS RAM Role: Metadata service 404/401, IMDSv2 token errors, credential expiration
  • Network: Timeout tuning, proxy setup, STS service failures
  • Security: AccessKey leakage cleanup, git history sanitization
  • Cross-platform: Path separators, macOS dylib loading, Docker networking
  • Runtime: Segfaults from null pointers, memory leaks, thread safety
  • Dependencies: Missing libssl.so / DLL resolution

Each FAQ follows: 现象 (symptom) → 根本原因 (root cause from code analysis) → 解决方案 (solution)

5. Best Practices

  • Use ECS RAM roles or OIDC in production (avoid long-term AccessKeys)
  • Enable IMDSv2 for metadata security hardening
  • Smart pointer lifecycle management to prevent leaks

6. Resources

  • Links to GitHub, AccessKey management console, RAM documentation

Example: Multi-environment credential management

Client createClient() {
    const char* env = std::getenv("APP_ENV");
    
    if (env && strcmp(env, "development") == 0) {
        Models::Config config;
        config.setType("access_key")
              .setAccessKeyId(getenv("DEV_AK"))
              .setAccessKeySecret(getenv("DEV_SECRET"));
        return Client(config);
    } else {
        // Production: use ECS RAM role (auto-refresh)
        Models::Config config;
        config.setType("ecs_ram_role");
        return Client(config);
    }
}

Technical Details

Documentation derived from comprehensive code analysis:

  • All credential providers (DefaultProvider, EcsRamRoleProvider, ProfileProvider, etc.)
  • Exception handling branches (network timeouts, file I/O, IMDS failures)
  • Test cases (test_edge_cases.cpp, test_integration_scenarios.cpp)
  • CMake build configuration (dependency resolution, runtime library conflicts)

FAQ scenarios extracted from:

  • EcsRamRoleProvider: IMDSv1/v2 fallback logic, 401/404 error paths
  • ProfileProvider: INI parsing, file permission checks
  • CMakeLists.txt: OpenSSL detection, Windows /MD enforcement, DLL copying
  • Test coverage: empty credentials, boundary conditions, concurrent access
Original prompt

请全面、深入地阅读当前项目的全部源代码(包括但不限于 README、配置文件、脚本、构建文件、测试用例等,不限于 PHP,可能包含 JavaScript、Go、Java、C++、Shell、YAML、JSON 等任意语言或格式),准确理解项目的功能逻辑、架构设计、依赖关系、运行机制及使用方式。

基于对代码的完整分析,请撰写一份面向终端用户的说明文档,核心目标是帮助用户在部署、配置和使用该项目时快速识别、理解并解决常见问题

文档需包含以下部分,并以 Markdown 格式输出:

  1. 项目简介
    简要说明项目用途、核心能力及典型应用场景。

  2. 使用前提与环境要求
    明确列出运行该项目所必需的:

    • 操作系统要求(如 Linux/macOS/Windows 版本)
    • 运行时环境(如 Node.js、Python、JDK、.NET、Docker 等)及其最低版本
    • 系统依赖(如特定库、命令行工具、内核特性等)
    • 网络或权限要求(如需要外网访问、root 权限、API 密钥等)
  3. 快速开始指南
    提供清晰、可复现的步骤,包括: a

    • 安装/构建方法(如 npm install、make、go build、docker-compose up 等)
    • 配置说明(如环境变量、配置文件模板)
    • 启动与验证命令(附带预期输出示例)
  4. 常见问题解答(FAQ) —— 重点部分
    请基于代码中所有可能引发失败或异常的逻辑路径,主动推断用户在真实使用中可能遇到的问题,并以问答形式详尽列出。每个问题应包含:

    • 问题现象:用户可能看到的错误信息、程序行为异常或日志内容(可引用具体报错)
    • 根本原因:结合代码逻辑说明为何会出现此问题(如:未处理空输入、配置字段缺失、文件路径硬编码、权限检查失败、超时阈值过小、特定平台不兼容等)
    • 解决方案或规避建议:提供具体、可操作的修复步骤或最佳实践

    特别注意:

    • 重点关注所有异常处理分支(如 try/catch、panic/recover、if err != nil、assert、错误码返回、日志警告等)
    • 分析边界条件、非法输入、缺失依赖、环境差异等易错场景
    • 即使官方文档或 README 未提及,只要代码中存在潜在使用陷阱,就必须纳入 FAQ
    • 测试test case通常也是为了验证代码及异常分支,也需要重点分析

文档语言应简洁明了、面向用户,避免堆砌技术细节,重点突出“问题—原因—解决”链条,确保非开发者也能理解并操作。

最终输出必须为结构清晰、排版规范的 Markdown 文档。
