Question

当我加载我的网站时，我收到错误400，我检查了所有内容，似乎没有任何结果。感谢

错误：

错误请求

浏览器（或代理）发送了此服务器无法理解的请求。

代码的作用：它需要用户输入，然后保存在文件中，以便跟踪用户从饮料机订购的内容

import flask
from flask import request
@app.route('/Half1File', methods=['POST']) 
def Half1File():
    print(request.form['projectFilepath'])
    Name = request.form['projectFilepath']
    print(Name)
    file = open("Tab.txt", "a")
    file.write('\n'+Name + ", Drink1Half")
    return
    print (Name)

@app.route("/Half1Tab") 
def Half1Tab():
    return """<html>
    <form action="/Half1File" method="post">
    Project file path: <input type="text" name="Name"><br>
    <input type="submit" value="Submit">
    </form>
    </html>"""

您必须修复表单中传递给request的值的名称，并在return语句中提供一个视图（我使其 easy ）。

import flask
from flask import request
app = flask.Flask(__name__)

@app.route('/Half1File', methods=['POST'])
def Half1File():
    print(request.form)
    print(request.form['Name'])
    Name = request.form['Name']
    print(Name)
    file = open("Tab.txt", "a")
    file.write('\n'+Name + ", Drink1Half")
    return """<html><div>OK : {} </div></html>""".format(Name)

@app.route("/Half1Tab")
def Half1Tab():
    return """<html>
    <form action="/Half1File" method="post">
    Project file path: <input type="text" name="Name"><br>
    <input type="submit" value="Submit">
    </form>
    </html>"""
