一、功能概述
DeepseekScanner实现了扫描源代码项目中的所有代码文件发送给deepseek进行安全审计的功能。具体细节包括扫描所有子目录中的代码文件，然后依次将代码文件切片发送到deepseek api进行智能代码审计。审计结果包含存在安全问题的代码文件、代码位置行数、安全漏洞问题名称、存在安全漏洞的代码块。最后将审计结果保存到文件中方便查阅。
二、具体功能介绍
扫描指定的代码项目目录代码语言：javascript代码运行次数：0运行复制<code class="javascript">//支持只扫描指定的文件后缀比如.php 只扫描.php文件 也可以扫描全部的文件类型def scan_directory(directory, file_types=None, scan_all=False): try: if scan_all: files_to_scan = [os.path.join(root, file) for root, _, files in os.walk(directory) for file in files] else: files_to_scan = [os.path.join(root, file) for root, _, files in os.walk(directory) for file in files if any(file.endswith(ft) for ft in file_types)] # Saving results to file scan_results = [] filename = f"scan_results.txt" directory = "./" filepath = os.path.join(directory, filename) for file_path in tqdm(files_to_scan, desc="Scanning files"): file_scan_results = scan_file(file_path, scan_results, directory) if file_scan_results is not None and len(file_scan_results) > 0: save_results_to_file(filepath, file_scan_results) except Exception as e: print(e)</code>
2.代码文件切片发送给deepseek做安全审计

四、总结
DeepseekScanner通过python+deepseek实现了python、php、java等语言项目代码审计，测试效果对于常见的安全问题甄别效果还是可以的，但可能也存在误报、错报等问题，需要再逐一帧对，不断完善。感兴趣的朋友可以在公众号回复"deepseekscanner"下载完整项目进行测试，包含代码项目和提供测试的漏洞代码项目。
