Code Review
本次代码变更主要是为企业CLA签署管理页面增加了通过邮箱或企业名称进行全局搜索的功能。整体实现思路清晰,通过在后端API中添加search参数,并在数据查询时根据参数内容构建不同的过滤条件来完成搜索。
我在代码中发现了一些可以改进的地方:
- 一个严重的安全漏洞:在
signing/infrastructure/repositoryimpl/corp_signing.go中,用户输入被直接用于构建正则表达式,这可能导致正则表达式拒绝服务(ReDoS)攻击。 - 搜索逻辑可以更完善:当前的搜索逻辑在某些边缘情况下(如企业名称恰好是邮箱格式)可能无法得到预期结果。
- 代码注释语言不统一:部分新增的代码注释使用了中文,建议统一为英文以提高代码库的可维护性。
具体的修改建议请见各文件的评论。

此处的搜索逻辑存在几个问题:
-
安全漏洞 (高危):直接使用
searchQuery作为正则表达式存在正则表达式拒绝服务(ReDoS)风险。恶意用户可以输入精心构造的正则表达式,导致服务器CPU占用过高。应使用regexp.QuoteMeta()对用户输入进行转义。 -
逻辑不完备:当前逻辑是“如果查询是邮箱格式,则按邮箱搜索,否则按企业名称搜索”。这会导致如果一个企业名称恰好是合法的邮箱格式(例如
email.com),则无法通过企业名称搜索到它。同时,如果用户输入部分邮箱地址,也无法进行搜索。更好的做法是同时在企业名称和邮箱两个字段中进行模糊搜索。 -
代码可维护性:代码中的注释是中文,为了方便团队中所有成员理解和维护,建议使用英文注释。
建议修改为使用 $or 操作符同时搜索企业名称和邮箱字段,并修复安全漏洞。请注意,此建议需要导入 regexp 包。
if searchQuery != "" {
// To prevent ReDoS, escape the search query for use in regex.
escapedQuery := regexp.QuoteMeta(searchQuery)
regexFilter := bson.M{"\$regex": escapedQuery, "\$options": "i"}
filter["\$or"] = bson.A{
bson.M{childField(fieldCorp, fieldName): regexFilter},
bson.M{childField(fieldRep, fieldEmail): regexFilter},
}

| adminAdded, sizeErr := ctl.GetBool("admin_added", false) | ||
| searchQuery := ctl.GetString("search") // 新增搜索参数 |

为了保持代码库语言一致性并提高可维护性,建议将此处的中文注释修改为英文。
| // 邮箱验证辅助函数 | |
| func isEmail(query string) bool { | |
| // 使用现有的邮箱验证逻辑 | |
| _, err := dp.NewEmailAddr(query) | |
| // isEmail is a helper function to validate an email address. | |
| func isEmail(query string) bool { | |
| // use the existing email validation logic | |
| _, err := dp.NewEmailAddr(query) |

需求背景:企业cla签署管理页面,新增分页功能后,数据查询时,数据检索范围仅为当前页,不支持全域检索,信息检索及确认难度大。
具体需求:申请在企业CLA签署管理系统 页面新增搜索框,且支持在全域通过邮箱地址或者企业名称进行信息搜索。
