包含返回 false

Question

我做了一個從 GIT 克隆的項目，與機器人有關。

事實是，在某些時候，這個機器人使用了 contains 函數，但這不起作用。 使用谷歌我能夠放置日志，並看到實際上列表包含字符串，但它總是返回false。

這是函數：

var isFromUser = contains(cm.config.users, username, 'exists')

這是“日志”

username: 230592242
cm.config.bot.owner: 9587763
isFromOwner: false
cm.config.users: 230592242
isFromUser: false

如您所見，用戶在 registersd 用戶中，但返回 false。

這些是我在 NPE 中使用的庫：

包含功能：

// Compare item with filter or another item
var checkItem = function(item, itemOrFilter) {

  // Defining array of filters
  var filters = []
  if (!Array.isArray(itemOrFilter)) {
    if (itemOrFilter.key != undefined)
      filters.push(itemOrFilter)
  } else {
    filters = itemOrFilter
  }

  // Filtering
  if (filters.length > 0) {
    var i = 0
    var match = true
    while (match && i < filters.length) {
      match = (item[filters[i].key] === filters[i].value)
      i++
    }
    return match
  }

  // Matching
  else {
    return (JSON.stringify(item) === JSON.stringify(itemOrFilter))
  }
}

// Search item in array.
var searchInArray = function(array, itemOrFilter, mode) {
  var found = { "index": -1, "filtered": []}
  var i = 0
  var end = false
  while ( i < array.length && !end) {
    end = (mode != 'filter' && mode != 'repetitions' && found.index != -1)
    if (checkItem(array[i], itemOrFilter)) {
      found.index = i
      found.filtered.push(array[i])
    }
    i++
  }
  return found
}

// Search substring or char in string.
var searchInString = function(string, item, mode) {
  var filtered = string.match(new RegExp(item, 'g'))
  var index    = (filtered) ? string.indexOf(filtered[0]) : -1
  var found    = { "index": index
                 , "filtered": filtered || []
                 }
  return found
}

// Search digit or subnumber in number.
var searchInNumber = function(number, item, mode) {
  var strnumber = number.toString()
  return searchInString(strnumber, item)
}


// Main function
module.exports = function contains (container, item, mode) {

  mode = (mode || 'index')
  var found = { "index": -1, "filtered": []}

  // Searching in number
  if (typeof container == "number")
    found = searchInNumber(container, item, mode)

  // Searching in string
  else if (typeof container == "string" || container instanceof String)
    found = searchInString(container, item, mode)

  // Searching in array
  else if (Array.isArray(container))
    found = searchInArray(container, item, mode)
  else console.log("Container type not allowed")

  // TODO: Search into object's properties
  //else if (container instanceof Object)  found = searchInObject(container, item)

  if (mode == 'exists') return found.filtered.length > 0
  if (mode == 'index')  return found.index
  if (mode == 'filter') return found.filtered
  if (mode == 'repetitions') return found.filtered.length
  console.log("Mode not allowed")
  return null
}

這些是我執行的日志：

// Filtering Messages
  var filterMessages = function(message) {
    // Formating message and preparing variables
    var username = (!message.from.username) ? message.from.id : message.from.username
    var messageToLog = logger.prepareMessage(message)
    // Checking message
    console.log('username: ' + username)
    console.log('cm.config.bot.owner: ' + cm.config.bot.owner)
    var isFromOwner = (username == cm.config.bot.owner)
    console.log('isFromOwner: ' + isFromOwner)
    console.log('cm.config.users: ' + cm.config.users)
    var isFromUser = contains(cm.config.users, username, 'exists')
    console.log('isFromUser: ' + isFromUser)
    var isCommand = (message.text && message.text.charAt(0) == '/' && message.text.length > 1)
    var activeUser = cmm.getActiveUserIdx(username)

這是日志中的輸出：

Answer 1

更新：如評論中所述，您必須使用如下for循環，因為cm.config.users是一個數組。

var isFromUser = false;
for(var i = 0; i < cm.config.users.length; i++) {
   isFromUser = contains(cm.config.users[i], username, 'exists');
   if(isFromUser) break;
}

該功能按預期工作，沒有問題。 當我與相同值運行函數230592242中提到cm.config.users: 230592242 ，其回歸true預期。 當使用除此以外的值運行時，它返回false 。

我在下面給出了一個示例片段來確認這一點，您可以通過單擊底部的Run code snippet來Run code snippet 。

您必須檢查在contains(cm.config.users, username, 'exists')使用的username的值是contains(cm.config.users, username, 'exists')

由於使用的配置值是230592242 cm.config.users: 230592242行中的cm.config.users: 230592242 ，這似乎是您要檢查的“用戶 ID”而不是“用戶名”。

這就是為什么你得到false 。
