Gin 渲染模板的方式
方式1：Go 标准库 “html/template”， template.ParseFiles()
方式2：“github.com/gin-gonic/gin”，gin.HTML()
一、Go 标准库 “html/template”
直接加载 login/inex.html
Handler.go
// GetIndex
// @Tags 首页
// @contact.name Allan
// @Success 200 {string} 首页
// @Router /index [get]
func (app *Config) GetIndex(c *gin.Context) {
idx, err := template.ParseFiles("login/index.html")
if err != nil {
panic(err)
}
idx.Execute(c.Writer, "首页")
}
login/index.html

二、“github.com/gin-gonic/gin”
c.HTML中的name必须与引用的tmpl文件内define定义的一致，直接使用chat/index.html不会加载内容。
Handler.go
// Chat
// @Tags 聊天
// @Description 聊天室
// @param userId query string false "用户ID"
// @param token query string false "Token"
// @contact.name Allan
// @Success 200 {string} success
// @Router /Chat [get]
func (app *Config) ChatRoom(c *gin.Context) {
session:= sessions.Default(c)
userId, _ := strconv.Atoi(c.Query("userId"))
token := c.Query("token")
if token != session.Get("loginToken") {
c.JSON(-1, gin.H{
"code": -1,
"message": "鉴权失败！",
})
return
}
user := models.User{}
user.ID = uint(userId)
user.Identity = token
c.HTML(http.StatusOK, "/chat/index.shtml", gin.H{
"code": 0,
"message": "success",
})
}
