Question

我上传了一个带有collectionFS的csv文件，然后我需要解析这个文件。

我就是这样做的：

Template.fsbanks.events "change .myFileInput": (event, template) ->
  FS.Utility.eachFile event, (file) ->
    Fsbanks.insert file, (err, fileObj) ->
      if err
        Notifications.danger err
      else
        console.log "File saved"
        console.log fileObj
    Meteor.call "importTransactions", file, (error, result) ->

然后我想要一些流星方法：

Meteor.methods

  importTransactions: (file) ->
    reader = new FileReader
    console.log file
    reader.readAsText file
    reader.onload = (event) ->
      data = $.csv.toObjects(event.target.result)
      console.log "File read #{data}"
      _.map data, (transaction) ->
        console.log transaction
        t = {}
        date = transaction["Value date"]
        date_array = date.split("/")
        new_date = date_array[2] + "-" + date_array[1] + "-" + date_array[0]
        #          console.log new_date
        t["account_nbr"] = transaction["Account number"]
        t["value_date"] = new Date new_date
        t["amount"] = transaction["Amount in the currency of the account"].replace(/\s/g, '')
        #          console.log t["amount"]
        t["description"] = transaction["Description"]
        Meteor.call "createTransaction", t, t["Entry number"], (error, entry_nbr) ->
          if error
            console.log error
          else
            console.log id

  createTransaction: (transaction, entry_nbr) ->

    Transactions.upsert
      entry_nbr: entry_nbr
    ,
      $set: transaction

    return entry_nbr

当我这样做时，collectionFS插入工作正常。

但是我遇到了insertTransaction服务器方法的问题：

Failed to execute 'readAsText' on 'FileReader': The argument is not a Blob.

如果我运行完全相同的代码客户端，它就可以工作。

运行代码服务器端应该更改什么？

这是我结束的代码。它很实用，但我真的不知道为什么......

在我的模型中（共享客户端/服务器）：

Meteor.methods

  importTransactions: (file) ->
    reader = new FileReader
    console.log file
    reader.readAsText file
    reader.onload = (event) ->
      data = $.csv.toObjects(event.target.result)
      console.log "File read #{data}"
      _.map data, (transaction) ->
        console.log transaction
        t = {}
        selectValues = {}
        date = transaction["Value date"]
        date_array = date.split("/")
        new_date = date_array[2] + "-" + date_array[1] + "-" + date_array[0]
        #          console.log new_date
        selectValues["account_nbr"] = transaction["Account number"]
        selectValues["value_date"] = new Date new_date
        selectValues["entry_nbr"] = parseInt transaction["Entry Number"]
        t["amount"] = transaction["Amount in the currency of the account"].replace(/\s/g, '')
        #          console.log t["amount"]
        t["description"] = transaction["Description"]
        Meteor.call "createTransaction", t, selectValues, (error, entry_nbr) ->
          if error
            console.log error
          else
            console.log id

在服务器上：

Meteor.methods
  createTransaction: (values, upsertValues) ->
    if upsertValues
      console.log "upserting transaction"
      console.log "transaction: #{values}"
      console.log "Values: #{upsertValues["entry_nbr"]}"
      Transactions.upsert upsertValues
      ,
        $set: values
      , (err, nbr) ->
        if err
          console.log err
        else
          console.log "upsert successful #{nbr}"
    else
      Transactions.insert values
      , (err, nbr) ->
        if err
          console.log err
        else
          console.log "insert successful #{nbr}"

Meteor方法filereader：参数不是blob
