使用Golang REST API创建数组

使用Gin框架创建REST API来返回包含4个标题和4个列表的内容，可以这样实现：

package main

import (
	"net/http"
	"time"
	
	"github.com/gin-gonic/gin"
)

type Job struct {
	ID    int       `db:"id" json:"id"`
	Title string    `db:"title" json:"title"`
	Body  string    `db:"body" json:"body"`
	Date  time.Time `db:"date" json:"date"`
}

type JobDetail struct {
	ID          int      `json:"id"`
	Title       string   `json:"title"`
	Description string   `json:"description"`
	Sections    []Section `json:"sections"`
}

type Section struct {
	SectionTitle string   `json:"sectionTitle"`
	Items        []string `json:"items"`
}

func main() {
	r := gin.Default()
	
	// 获取职位列表
	r.GET("/jobs", func(c *gin.Context) {
		jobs := []Job{
			{ID: 1, Title: "高级Go开发工程师", Body: "负责后端API开发", Date: time.Now()},
			{ID: 2, Title: "前端开发工程师", Body: "负责React前端开发", Date: time.Now()},
			{ID: 3, Title: "DevOps工程师", Body: "负责CI/CD流程", Date: time.Now()},
			{ID: 4, Title: "产品经理", Body: "负责产品规划", Date: time.Now()},
		}
		c.JSON(http.StatusOK, jobs)
	})
	
	// 获取职位详情，包含4个标题和4个列表
	r.GET("/jobs/:id", func(c *gin.Context) {
		id := c.Param("id")
		
		// 根据ID返回对应的职位详情
		jobDetail := JobDetail{
			ID:          1,
			Title:       "高级Go开发工程师",
			Description: "负责微服务架构设计和开发",
			Sections: []Section{
				{
					SectionTitle: "职位要求",
					Items: []string{
						"3年以上Go开发经验",
						"熟悉Gin/Echo框架",
						"了解微服务架构",
						"熟悉Docker和Kubernetes",
					},
				},
				{
					SectionTitle: "工作职责",
					Items: []string{
						"设计和开发RESTful API",
						"编写高质量可维护的代码",
						"参与系统架构设计",
						"性能优化和问题排查",
					},
				},
				{
					SectionTitle: "技术要求",
					Items: []string{
						"精通Go语言",
						"熟悉MySQL/PostgreSQL",
						"了解消息队列(RabbitMQ/Kafka)",
						"熟悉Git工作流",
					},
				},
				{
					SectionTitle: "福利待遇",
					Items: []string{
						"五险一金",
						"年度体检",
						"带薪年假",
						"技术培训机会",
					},
				},
			},
		}
		
		c.JSON(http.StatusOK, jobDetail)
	})
	
	r.Run(":8080")
}

如果需要从数据库获取数据，可以这样实现：

func getJobDetails(c *gin.Context) {
	id := c.Param("id")
	
	var job Job
	// 从数据库获取基础职位信息
	db.Where("id = ?", id).First(&job)
	
	// 构建包含4个标题和4个列表的详情
	jobDetail := JobDetail{
		ID:          job.ID,
		Title:       job.Title,
		Description: job.Body,
		Sections: []Section{
			{
				SectionTitle: "职位要求",
				Items:        getJobRequirements(job.ID),
			},
			{
				SectionTitle: "工作职责",
				Items:        getJobResponsibilities(job.ID),
			},
			{
				SectionTitle: "技术要求",
				Items:        getTechnicalRequirements(job.ID),
			},
			{
				SectionTitle: "福利待遇",
				Items:        getBenefits(job.ID),
			},
		},
	}
	
	c.JSON(http.StatusOK, jobDetail)
}

// 从数据库获取各项内容的辅助函数
func getJobRequirements(jobID int) []string {
	var requirements []string
	db.Table("job_requirements").Where("job_id = ?", jobID).Pluck("requirement", &requirements)
	return requirements
}

func getJobResponsibilities(jobID int) []string {
	var responsibilities []string
	db.Table("job_responsibilities").Where("job_id = ?", jobID).Pluck("responsibility", &responsibilities)
	return responsibilities
}

func getTechnicalRequirements(jobID int) []string {
	var techRequirements []string
	db.Table("technical_requirements").Where("job_id = ?", jobID).Pluck("requirement", &techRequirements)
	return techRequirements
}

func getBenefits(jobID int) []string {
	var benefits []string
	db.Table("benefits").Where("job_id = ?", jobID).Pluck("benefit", &benefits)
	return benefits
}

前端可以通过访问 /jobs 获取职位列表，点击具体职位时访问 /jobs/1 获取包含4个标题和4个列表的详细信息。
