What’s wrong with this Flask request? [duplicate]

Solution

Go

  @app.route('/button', methods=["GET", "POST"])
  def button():
    if request.method == "GET":
        return render_template("index.html")
    if request.method == "POST":
      dlink = request.form.get("linkHolder")
      print(dlink)
      return render_template("index.html", dlink=dlink)
