Question

我有一个要输入到.txt文件的变量“ inputed_email”。但是，您将如何在Flask中完成此任务？任何帮助表示赞赏。谢谢！

@app.route('/', methods=['GET', 'POST'])
def my_form():
    inputed_email = request.form.get("email")
    if request.method == 'POST' and inputed_email:

        # code that writes "inputed_email" to a .txt file

        return render_template('my-form.html', email=inputed_email)
    return render_template('my-form.html')

写入文件与Flask无关。您可以学习如何读写文件here。请记住，写入大量数据很慢，并且会降低请求的速度。

if request.method == 'POST' and inputed_email:
    # open is a built-in function, w is for write-mode (default is read)
    with open('workfile', 'w') as f: 
         f.write(inputed_email)
    return render_template(....)
