Question

当客户端发送请求时，我想知道客户端请求数据的字段是什么。例如，

Sub InsertRev()
    Dim c As Range
    Set Rng = ActiveSheet.Range("d1:d5000")
    For dblCounter = Rng.Cells.Count To 1 Step -1
        Set c = Rng(dblCounter)
        If c.Value Like "*TOTAL*" Then
            c.EntireRow.Insert xlShiftDown, xlFormatFromLeftOrAbove
        End If
    Next dblCounter
End Sub

在上述请求中，客户端已请求用户的myApp.controller('SpicyController', ['$scope', '$http', 'userService', , function字段和{ user { name address } }字段。如何在执行查询时知道/获取这些指定的字段，即sangria-graphql Server中的名称和地址？

您必须在4th

中使用resolve()参数

resolve: (obj, args, auth, fieldASTs) => {
    /* all your fields are present in selections
       please check the fieldASTs JSON path it may vary if you are using relay
                                                                connections */
  const requiredFields = fieldASTs.fieldNodes[0].selectionSet.selections.map(
      (set) => set.name.value
   );
  // requiredFields will contain the name and address
}
/* fieldASTs contains fieldNames, fieldNodes and every details about your Schema 
 you can get your specified fields inside fieldNodes like */

知道GraphQL / Sangria-Graphql中服务器端的指定字段
