我正在尝试抓取网页以查找包含两个关键字的商品链接。我遇到了一个问题,当脚本应该检查两个时,脚本会导航到包含两个关键字之一的第一个链接。
这是代码:
from flask import Flask, render_template, url_for, redirect, request, session
app = Flask(__name__)
@app.route('/', methods=["POST", "GET"])
def purchase():
try:
if request.method == "POST":
email = request.form["email"]
# Query the data base to find the exact amount and name of buyer
session["user"] = email
return redirect(url_for("proceed"))
else:
return render_template("index.html",logged_in=True)
except Exception as e:
return(str(e))
@app.route("/confirm")
def proceed():
# Get information and create another form
if "user" in session:
return f"""<h1>{session["user"]}</h1>"""
else:
return f"""<h1>No email found</h1>"""
if __name__ == "__main__":
app.run()
如何获取实际检查两个关键字的信息?还是这样正确,而我的问题出在其他地方?
谢谢。
