If i use html template，How can I get response body(or HTML)？ not use HttpRequest Client，do anyone kown it?
Hello @caimingyi484,
You can already do that using the app.View method, after app.Build or Listen/Run. It accepts an io.Writer at its first argument, the rest parameters are the usual, the ones that ctx.View accepts.
In that io.Writer you can use w := new(bytes.Buffer) from standard import "bytes" package. Then w.String() to get its contents or w.Bytes() to get them as binary ([]byte). Actually there is an example which writes the template to the terminal(os.Stdout), take a look at: https://github.com/kataras/iris/blob/master/_examples/view/write-to/main.go
Let me write down a simple example for you:
import (
"bytes"
"github.com/kataras/iris/v12"
)
func main() {
// Register the views.
app.RegisterView(iris.HTML("./views", ".html"))
// [YOUR ROUTES HERE....]
// You need to call `app.Build` manually before using the `app.View` func,
// so templates are built in that state.
// If you are going to use `app.View` after `Listen` then you can SKIP this:
app.Build()
w := new(bytes.Buffer)
err := app.View(w, "template.html", "layout.html", map[string]interface{}{
"Title": "This is my e-mail title",
"Body": "This is my e-mail body",
})
if err!=nil{
app.Logger().Fatal(err)
}
templateAsBytes := w.Bytes()
// or
templateAsString := w.String()
// ...
app.Listen(":8080")
}
And since you can do that, you can also do that from inside a Handler through ctx.Application().View.
Note that, if you are not going to use
app.Viewfrom your main function, then you can remove theapp.Buildline.
func handler(ctx iris.Context){
app := ctx.Application()
w := new(bytes.Buffer)
err := app.View(w, "template.html", "layout.html", map[string]interface{}{
"Title": "This is my e-mail title",
"Body": "This is my e-mail body",
})
if err!=nil {
app.Logger().Warn(err)
// [...handle error]
}
templateAsBytes := w.Bytes()
// or
templateAsString := w.String()
// ...
}
Please don't forget to star Iris, this is all we ask.
Have fun! Gerasimos Maropoulos.
