使用javascript將mongo集合中的所有數據轉換為文本文件

Question

我有這種語法的Mongo集合。 如何將每個文件導出到包含數組的文本文件中？

{
      _id: 1,
      "author": [
        {
          "fname": "Petr",
          "lname": "Kocircurka"
        }
      ],
      "title": "On topological dynamics of Turing machines",
      "journal": "Theor. Comput. Sci.",
      "volume": "174",
      "pages": [
        {
          "FirstNumber": "203",
          "LastNumber": "216"
        }
      ],
      "year": "1997",
      "url": "http://www.sciencedirect.com/science/journal/03043975/"
    }{
      _id: 2,
      "author": [
        {
          "fname": "Aviezri",
          "lname": "Fraenkel"
        },
        {
          "fname": "Jamie",
          "lname": "Simpson"
        }
      ],
      "title": "The exact number of squares in Fibonacci words",
      "journal": "Theor. Comput. Sci.",
      "volume": "218",
      "pages": [
        {
          "FirstNumber": "95",
          "LastNumber": "106"
        }
      ],
      "year": "1999",
      "url": "http://www.sciencedirect.com/science/journal/03043975/"
    }

謝謝

Answer 1

mongoexport --db yourDbName --collection collectionName --out fileName.json -u userName -p yourPassword

Answer 2

如果創建數據庫時未使用用戶名和密碼，則可以使用以下命令，該命令將為您定義的每個集合提供json文件

 mongoexport --db databaseName --collection CollectionName --out fileName.json
