Gemini 辅助网络安全漏洞分析

以下代码示例展示如何利用 Gemini API（假设为模拟接口）辅助识别常见漏洞（如 SQL 注入）并提供修复建议：

csharp 复制代码

using System;
using System.Net.Http;
using System.Threading.Tasks;
using Newtonsoft.Json;

public class GeminiSecurityHelper
{
    private const string GeminiApiEndpoint = "https://api.gemini-mock.com/analyze";
    
    public async Task<string> AnalyzeVulnerability(string codeSnippet)
    {
        var payload = new 
        {
            code = codeSnippet,
            context = "web_application"
        };

        using (var client = new HttpClient())
        {
            var response = await client.PostAsJsonAsync(GeminiApiEndpoint, payload);
            if (response.IsSuccessStatusCode)
            {
                var result = await response.Content.ReadAsStringAsync();
                var analysis = JsonConvert.DeserializeObject<GeminiResponse>(result);
                return FormatRecommendation(analysis);
            }
            return "API request failed";
        }
    }

    private string FormatRecommendation(GeminiResponse analysis)
    {
        return $"Detected: {analysis.VulnerabilityType}\n" +
               $"Risk Level: {analysis.RiskScore}/10\n" +
               $"Solution: {analysis.Recommendation}\n" +
               $"Code Example:\n{analysis.PatchedCode}";
    }
}

public class GeminiResponse
{
    public string VulnerabilityType { get; set; }
    public int RiskScore { get; set; }
    public string Recommendation { get; set; }
    public string PatchedCode { get; set; }
}

使用示例

csharp 复制代码

// 检测SQL注入漏洞
var vulnerableCode = "SELECT * FROM users WHERE username = '" + userInput + "'";
var analyzer = new GeminiSecurityHelper();
var result = await analyzer.AnalyzeVulnerability(vulnerableCode);
Console.WriteLine(result);

预期输出结构

复制代码

Detected: SQL Injection
Risk Level: 9/10
Solution: Use parameterized queries
Code Example:
var cmd = new SqlCommand("SELECT * FROM users WHERE username = @param");
cmd.Parameters.AddWithValue("@param", userInput);

扩展功能建议

添加漏洞模式缓存层减少API调用
集成OWASP Top 10漏洞数据库
支持多语言代码分析（需调整API参数）
添加严重性阈值自动告警功能

注意：实际实现需替换为真实的Gemini API端点并处理认证。此示例假设API返回结构化漏洞分析数据。
