MongoDB 保存正则表达式，如电子邮件地址、用户名 [英] MongoDB Save Regular Expressions like email address, username

问题描述

如何在mongodb中保存正则表达式模式

How to save regular expression patterns in mongodb.

示例:电子邮件地址模式

/[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+.[A-Za-z]{2,4}/(电子邮件地址)，

示例:用户名模式

/[A-Za-z0-9-\@.,_]{6,50}/(用户名).

这里我验证了用户类型，就像我需要根据模式验证电子邮件地址一样.

Here i validated for user type, in the same way i need to validate email address based on the pattern .

{
    "_id" : "Validation_rule",
    "flowId" : "String",
    "lineOfBusiness" : "String",
    "description" : "Invalid User type.It should be either of 'Admin', 'enduser'",
    "spelExprRecord" : {
        "className" : "com.my.Account.User",
        "booleanSpelExpression" : "(role.equalsIgnoreCase('admin') == true) || (role.equalsIgnoreCase('enduser') == true) "
    }
}

推荐答案

这是使用验证器创建的示例集合.只有满足验证器中指定的 3 个三个条件，才会插入/更新文档

Here's a sample collection created with validator. A document will be inserted / updated only if the 3 three conditions specified in the validators are satisfied

db.createCollection( "contacts",
   { validator: { $and:
      [
         { phone: { $type: "string" } },
         { email: { $regex: /@mongodb\.com$/ } },
         { status: { $in: [ "Unknown", "Incomplete" ] } }
      ]
   }
} )
