I'm getting a (TypeError: expected string or bytes-like object) while working with pytube library

Question

python

from flask import Flask, request, render_template
from pytube import YouTube
import pytube

app = Flask(__name__)


@app.route("/", methods=["POST", "GET"])
def find():
    search1 = request.form.get("search")
    print(search1)
    print(type(search1))
    subt = pytube.YouTube(search1)  # <-- Error occurs in this line.
    print(subt)
    cap = subt.captions.get_by_language_code('en')
    print("Video english subtitle")
    print(cap.generate_srt_captions())
    return render_template("sub.html")


if __name__ == "__main__":
    app.run(debug=True)

错误： TypeError：预期的字符串或类似字节的对象

结果 = regex.search（字符串）

类型错误：预期的字符串或类字节对象

Answer 1

from flask import Flask, request, render_template
from pytube import YouTube
import pytube

app = Flask(__name__)

@app.route("/", methods=["GET"])
def index():
    return render_template("sub.html")


@app.route("/test", methods=["POST"])
def find():
    search1 = request.form.get("search")
    print(search1)
    print(type(search1))
    subt = pytube.YouTube(search1)
    cap = subt.captions.get_by_language_code('en')
    print("Video english subtitle")
    print(cap.generate_srt_captions())
    return render_template("sub.html", cap=cap)


if __name__ == "__main__":
    app.run(debug=True)
