在Go语言中构建数组的切片。

Construct Array from Slices in Go

问题

给定以下代码:

var positionTitles []string
var positionRelationships []string
var positionInstitutions []string

positionTitles = ["Director" "Provost" "Assistant Provost"]
positionRelationships = ["Tenured Professor" "Lecturer" "Adjunct Professor"]
positionInstitutions = ["UCSC" "UCB" "USC"]

如何构建一个类似下面的数组:

Positions :=
 [{
   PositionTitle: "Director",
   PositionRelationships: "Tenured Professor",
   PositionInstitution: "UCSC",
  },
  {
   PositionTitle: "Provost",
   PositionRelationships: "Lecturer",
   PositionInstitution: "UCB",
  },
  {
   PositionTitle: "Assistant Provost",
   PositionRelationships: "Adjunct Professor",
   PositionInstitution: "USC",
  }]

目标是遍历 Positions。

我已经在 Go Playground 上开始了一个示例:
http://play.golang.org/p/za_9U7eHHT

英文:

Given the following:

var positionTitles []string
var positionRelationships []string
var positionInstitutions []string

positionTitles = ["Director" "Provost" "Assistant Provost"]
positionRelationships = ["Tenured Professor" "Lecturer" "Adjunct Professor"]
positionInstitutions = ["UCSC" "UCB" "USC"]

How would I construct an array that looks like such:

Positions :=
 [{
   PositionTitle: "Director",
   PositionRelationships: "Tenured Professor",
   PositionInstitution: "UCSC",
  },
  {
   PositionTitle: "Provost",
   PositionRelationships: "Lecturer",
   PositionInstitution: "UCB",
  },
  {
   PositionTitle: "Assistant Provost",
   PositionRelationships: "Adjunct Professor",
   PositionInstitution: "USC",
  }]

The goal is to iterate over the Positions.

你可以创建一个类型来保存所有的片段,并迭代这些片段,例如:

type Position struct {
    Title, Relationship, Institution string
}

positions := make([]Position, len(positionTitles))
for i, title := range positionTitles {
    positions[i] = Position{
        Title:        title,
        Relationship: positionRelationships[i],
        Institution:  positionInstitutions[i],
    }
}

然而,如果你只需要进行迭代,不需要创建一个类型。可以参考for循环的主体部分。

英文:

You can create a type that would hold all the pieces and iterate over the slices such that

type Position struct {
    Title, Relationship, Institution string
}

positions := make([]Position, len(positionTitles))
for i, title := range positionTitles {
	positions[i] = Position{
		Title:        title,
		Relationship: positionRelationships[i],
		Institution:  positionInstitutions[i],
	}
}

However, if you need it only to iterate, you don't need to create a type. See body of the for.

我会创建一个包含所需信息的Position结构体:

type Position struct {
    PositionTitle         string
    PositionRelationships string
    PositionInstitution   string
}

然后创建一个该结构体的数组(或切片),以便对它们进行迭代。这里有一个可工作的示例:http://play.golang.org/p/s02zfeNJ63

英文:

I would create a Position struct containing the informations you need :

type Position struct {
PositionTitle         string
PositionRelationships string
PositionInstitution   string
}

and create an array (or slice) of those structs to iterate over them. Here is a working example : http://play.golang.org/p/s02zfeNJ63
