I am having trouble with a Go Buffalo web app I am trying to build. I basically have a standard form on the front end that, when clicked, is supposed to send a tweet to the Users twitter account. I get a "500: CSRF Not found" when doing so. I am using the Go Buffalo framework for the web app and go-twitter to handle the twitter API.
I have little to no experience with CSRF so was hoping somebody could help me in this specific case.
The tweet.HTML:
<h3>Tweet tweet!</h3>
<form action="/tweet" method="POST">
<div class="form-group">
<label for="tweet">Your tweet:</label>
<input type="text" name="tweet" class="form-control" id="tweet" placeholder="Tweet body"
value="">
</div>
<button type="submit" class="btn btn-primary">Send</button>
</form>
The router:
app.POST("/tweet", SendHandler)
Tweet.go (Contains SendHandler function):
package actions
import (
"fmt"
"log"
"os"
"twitapp/twitter"
"github.com/gobuffalo/buffalo"
)
var creds = twitter.Credentials{
AccessToken: os.Getenv("ACCESS_TOKEN"),
AccessTokenSecret: os.Getenv("ACCESS_TOKEN_SECRET"),
APIKey: os.Getenv("API_KEY"),
APISecret: os.Getenv("API_SECRET"),
}
type TweetForm struct {
TweetBody string
}
// TweetHandler is the handler for the Tweet page
func TweetHandler(c buffalo.Context) error {
return c.Render(200, r.HTML("tweet.html"))
}
//SendHandler Function used by tweet.html to send the tweet/
//Takes in variables from twitter/server.go
func SendHandler(c buffalo.Context) error {
var form TweetForm
body := form.TweetBody
fmt.Printf("%+v\n", creds)
//Gets the client from the twitter package
client, err := twitter.GetClient(&creds)
if err != nil {
log.Println("Error getting Twitter Client")
log.Println(err)
}
//Sending the actual tweet. Body from the form
tweet, resp, err := client.Statuses.Update(body, nil)
if err != nil {
log.Println(err)
}
log.Printf("%+v\n", resp)
log.Printf("%+v\n", tweet)
return c.Redirect(302, "/tweet/confirm")
}
There is also a GetClient function that is called from the SendHandler function but I cant imagine the problem is in there as it standard code that sets up the twitter client for the call. Appreciate any help/pointing in the right direction. I dont have enough knowledge of CSRF to apply it to this at the moment.
After looking through the GoBuffalo docs, and in particular THIS part of the forms page, All i had to do was add this line of code to my form (tweet.html) to handle the authenticity token.
<input name="authenticity_token" type="hidden" value="<%= authenticity_token %>">
