How to return html on Gin?
问题
我正在尝试渲染一个已经存在于字符串中的HTML，而不是在Gin框架上渲染一个模板。
在GET("/")函数中，c.HTML函数期望渲染一个模板。
但是在POST("/markdown")中，我已经将HTML渲染到了一个字符串上。
我该如何在Gin上返回它？
package main
import (
"github.com/gin-gonic/gin"
"github.com/russross/blackfriday"
"log"
"net/http"
"os"
)
func main() {
router := gin.New()
router.Use(gin.Logger())
router.LoadHTMLGlob("templates/*.tmpl.html")
router.GET("/", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.tmpl.html", nil)
})
router.POST("/markdown", func(c *gin.Context) {
body := c.PostForm("body")
log.Println(body)
markdown := blackfriday.MarkdownCommon([]byte(c.PostForm("body")))
log.Println(markdown)
// TODO: 在返回时渲染markdown内容
})
router.Run(":5000")
}

I'm trying to render a HTML that's already on a string instead of rendering a template on Gin framework.
The c.HTML function on GET("/") function expects a template to be rendered.
But on POST("/markdown") I've rendered that HTML on a string already.
How can I return it on Gin?
package main
import (
"github.com/gin-gonic/gin"
"github.com/russross/blackfriday"
"log"
"net/http"
"os"
)
func main() {
router := gin.New()
router.Use(gin.Logger())
router.LoadHTMLGlob("templates/*.tmpl.html")
router.GET("/", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.tmpl.html", nil)
})
router.POST("/markdown", func(c *gin.Context) {
body := c.PostForm("body")
log.Println(body)
markdown := blackfriday.MarkdownCommon([]byte(c.PostForm("body")))
log.Println(markdown)
// TODO: render markdown content on return
})
router.Run(":5000")
}

你可以将处理过的 Markdown 字节数组作为 RAW Data 返回，并将 content-type 设置为 text/html; charset=utf-8。
以下是示例代码：
router.POST("/markdown", func(c *gin.Context) {
body, ok := c.GetPostForm("body")
if !ok {
c.JSON(http.StatusBadRequest, "badrequest")
return
}
markdown := blackfriday.MarkdownCommon([]byte(body))
c.Data(http.StatusOK, "text/html; charset=utf-8", markdown)
})
英文:
You can return the processed markdown byte array as a RAW Data and set content-type as text/html; charset=utf-8
This is how it may look like
router.POST("/markdown", func(c *gin.Context) {
body, ok := c.GetPostForm("body")
if !ok {
c.JSON(http.StatusBadRequest, "badrequest")
return
}
markdown := blackfriday.MarkdownCommon([]byte(body))
c.Data(http.StatusOK, "text/html; charset=utf-8", markdown)
})

你还可以使用常量来表示内容类型：
const (
ContentTypeBinary = "application/octet-stream"
ContentTypeForm = "application/x-www-form-urlencoded"
ContentTypeJSON = "application/json"
ContentTypeHTML = "text/html; charset=utf-8"
ContentTypeText = "text/plain; charset=utf-8"
)
c.Data(http.StatusOK, ContentTypeHTML, []byte("<html></html>"))
英文:
You can also use constants for content types:
const (
ContentTypeBinary = "application/octet-stream"
ContentTypeForm = "application/x-www-form-urlencoded"
ContentTypeJSON = "application/json"
ContentTypeHTML = "text/html; charset=utf-8"
ContentTypeText = "text/plain; charset=utf-8"
)
c.Data(http.StatusOK, ContentTypeHTML, []byte("<html></html>"))

将blackfriday.MarkdownCommon()的输出转换为template.HTML，如下所示：
markdown := blackfriday.MarkdownCommon([]byte(c.PostForm("body")))
c.HTML(http.StatusOK, "markdown.html", gin.H {
"markdown": template.HTML(markdown),
})
英文:
Convert the output of blackfriday.MarkdownCommon() to template.HTML like:
markdown := blackfriday.MarkdownCommon([]byte(c.PostForm("body")))
c.HTML(http.StatusOK, "markdown.html", gin.H {
"markdown": template.HTML(markdown),
})
