我正在循环我的API响应并将其添加到这样的html模板,
// Following sends same information as above to the browser as html
t, err := template.New("TopMovies").Parse(`
{{define "TopMovies"}}
<html>
<ul>
{{$ImgUrl := "http://image.tmdb.org/t/p/w185" }}
{{range $movies := .Results}}
<li>{{$ImgUrl}}{{$movies.PosterPath}}</li>
<li>{{$movies.Adult}}</li>
<li>{{$movies.Overview}}</li>
<li>{{$movies.ReleaseDate}}</li>
<li>{{$movies.GenreIds}}</li>
<li>{{$movies.Id}}</li>
<li>{{$movies.OriginalTitle}}</li>
<li>{{$movies.OriginalLanguage}}</li>
<li>{{$movies.Title}}</li>
<li>{{$ImgUrl}}{{$movies.BackdropPath}}</li>
<li>{{$movies.Popularity}}</li>
<li>{{$movies.VoteCount}}</li>
<li>{{$movies.Video}}</li>
<li>{{$movies.VoteAverage}}</li>
{{end}}
</ul>
</html>
{{end}}
`)
err = t.ExecuteTemplate(w, "T", p) // This writes the client response
}
我的印象是我应该可以在我这样的html模板中调用它,
{{.TopMovies}}
但是当我运行应用程序时,数据不会显示在我调用它的html页面中.我在这里缺少什么?
我创建了这样的结构,
//A Page structure
type Page struct {
Title string
TopMovies string
}
然后我像这样创建我的手柄,
func TopMoviesHandler(w http.ResponseWriter, r *http.Request) {
res, err := http.Get(url)
if err != nil {
panic(err)
}
defer res.Body.Close()
body, err := ioutil.ReadAll(res.Body)
if err != nil {
panic(err)
}
var p Payload
err = json.Unmarshal(body, &p)
if err != nil {
panic(err)
}
// Following sends same information as above to the browser as html
t, err := template.New("TopMovies").Parse(`
{{define "TopMovies"}}
<html>
<ul>
{{$ImgUrl := "http://image.tmdb.org/t/p/w185" }}
{{range $movies := .Results}}
<li>{{$ImgUrl}}{{$movies.PosterPath}}</li>
<li>{{$movies.Adult}}</li>
<li>{{$movies.Overview}}</li>
<li>{{$movies.ReleaseDate}}</li>
<li>{{$movies.GenreIds}}</li>
<li>{{$movies.Id}}</li>
<li>{{$movies.OriginalTitle}}</li>
<li>{{$movies.OriginalLanguage}}</li>
<li>{{$movies.Title}}</li>
<li>{{$ImgUrl}}{{$movies.BackdropPath}}</li>
<li>{{$movies.Popularity}}</li>
<li>{{$movies.VoteCount}}</li>
<li>{{$movies.Video}}</li>
<li>{{$movies.VoteAverage}}</li>
{{end}}
</ul>
</html>
{{end}}
`)
err = t.ExecuteTemplate(w, "T", p) // This writes the client response
}
然后在main.go
http.HandleFunc("/TopPicks", TopMoviesHandler)
TopPicks.html
{{define "TopPicks"}}
{{template "header" .}}
<div class="content">
{{.TopMovies}}
</div>
{{template "footer" .}}
{{end}}
这是什么工作,
func aboutHandler(w http.ResponseWriter, r *http.Request) {
display(w, "about", &Page{Title: "About"})
}
我可以用与前面提到的相同的方式为页面添加标题但是使用display()
并在HTML模板中
<title>{{.Title}}</title>
我怎样才能为json响应做这项工作?
最佳答案 看起来你正在做{{define“body”}},但后来要求ExecuteTemplate执行“T”,它没有在任何地方定义.
我想你想:t.ExecuteTemplate(w,“body”,p)
总而言之,如果您只想使用多个模板,可以通过创建主顶级模板,然后将所有部件解析为子模板来实现.
这是一个例子(on Play).
轻松更改以遍历文件系统并加载所有模板,然后只需执行与http.Request路径匹配的模板.
package main
import "html/template"
import "os"
import "log"
var mainText = `
Normal page stuff
{{ template "_header_" . }}
{{ template "body" . }}
`
var bodyText = `
Body has: {{ .Thing }}
`
var headerText = `
I am header text
`
type Stuff struct {
Thing string
}
func main() {
t := template.New("everything")
// parse all templates you may want
template.Must(t.New("/").Parse(mainText))
template.Must(t.New("_header_").Parse(headerText))
template.Must(t.New("body").Parse(bodyText))
if err := t.ExecuteTemplate(os.Stdout, "/", Stuff{"I am a thing"}); err != nil {
log.Fatal("Failed to execute:", err)
}
}
