脚本说明

• 该脚本用于批量修改mongodb字段,根据时间范围循环执行.

• 增加工作时间范围判断和mongodb 认证判断

• 增加日志输出

• 脚本代码

使用命令行批量进行替换修改操作

• 调整前结果

> db.fastdfs.find()
{ "_id" : ObjectId("65a9e4cb03febb56295304d4"),  "fastdfs_url" : "http://1.1.1.1:8099/g10/M00/39/D9/CmQA6WEJ5NGAEtsoAABqUGfXheo386.wav" }

• 详细命令如下

db.ent_record_fastdfs_url.find({ $or: [{ "fastdfs_url": { $regex: /1.1.1.1/ } }, { "original_url": { $regex: /1.1.1.1/ } }] }).forEach(function(doc) {
   db.ent_record_fastdfs_url.update(
      { "_id": doc._id },
      {
         $set: {
            "fastdfs_url": doc.fastdfs_url.replace(/jsdx.ccod.com/g, "2.2.2.2"),
            "original_url": doc.original_url.replace(/jsdx.ccod.com/g, "2.2.2.2"),
            // Add more fields here if needed
         }
      }
   );
});

• 调整后结果

> db.fastdfs.find()
{ "_id" : ObjectId("65a9e4cb03febb56295304d4"),  "fastdfs_url" : "http://2.2.2.2:8099/g10/M00/39/D9/CmQA6WEJ5NGAEtsoAABqUGfXheo386.wav" }
