### 10.4 错误日志 [测试过程中的错误日志汇总] ================================================ FILE: go/README.md ================================================ # Re-movery (Go版本) Re-movery是一个强大的安全漏洞扫描工具，用于检测代码中的潜在安全问题。Go版本提供了高性能的扫描能力和多种接口选项。 ## 功能特点 - 支持多种编程语言（目前支持Python和JavaScript） - 提供命令行、Web界面和API接口 - 生成HTML、JSON和XML格式的报告 - 支持并行扫描和增量扫描 - 与CI/CD工具集成（GitHub Actions、GitLab CI） - VS Code扩展支持 ## 安装 ### 从源码安装 ```bash git clone https://github.com/re-movery/re-movery.git cd re-movery/go go install ./cmd/movery ``` ### 使用Go工具安装 ```bash go install github.com/re-movery/re-movery/cmd/movery@latest ``` ## 使用方法 ### 命令行扫描 ```bash # 扫描单个文件 movery scan --file path/to/file.py # 扫描目录 movery scan --dir path/to/directory # 排除特定文件或目录 movery scan --dir path/to/directory --exclude "node_modules,*.min.js" # 生成HTML报告 movery scan --dir path/to/directory --output report.html # 启用并行处理 movery scan --dir path/to/directory --parallel # 启用增量扫描 movery scan --dir path/to/directory --incremental ``` ### 启动Web界面 ```bash # 默认配置（localhost:8080） movery web # 自定义主机和端口 movery web --host 0.0.0.0 --port 8080 # 启用调试模式 movery web --debug ``` ### 启动API服务器 ```bash # 默认配置（localhost:8081） movery server # 自定义主机和端口 movery server --host 0.0.0.0 --port 8081 # 启用调试模式 movery server --debug ``` ### 生成集成文件 ```bash # 生成GitHub Actions工作流文件 movery generate github-action # 生成GitLab CI配置文件 movery generate gitlab-ci # 生成VS Code扩展配置文件 movery generate vscode-extension ``` ## API文档 ### 扫描代码 ``` POST /api/scan/code Content-Type: application/json { "code": "代码内容", "language": "python", "fileName": "example.py" } ``` ### 扫描文件 ``` POST /api/scan/file Content-Type: multipart/form-data file: [文件内容] ``` ### 扫描目录 ``` POST /api/scan/directory Content-Type: application/json { "directory": "/path/to/directory", "excludePatterns": ["node_modules", "*.min.js"], "parallel": true, "incremental": false } ``` ### 获取支持的语言 ``` GET /api/languages ``` ## 配置 Re-movery可以通过命令行参数或配置文件进行配置。配置文件支持YAML、JSON和TOML格式。 ```yaml # re-movery.yaml scanner: parallel: true incremental: true confidenceThreshold: 0.7 web: host: localhost port: 8080 debug: false server: host: localhost port: 8081 debug: false ``` ## 开发 ### 构建 ```bash cd go go build -o movery ./cmd/movery ``` ### 测试 ```bash go test ./... ``` ### 贡献 欢迎提交Pull Request和Issue。请确保您的代码符合Go的代码规范，并通过所有测试。 ##
