问题描述
我收到了此Python代码，并以某种方式收到了错误消息:
I got this Python Code, and somehow I get the Error Message:
File "/app/identidock.py", line 13, in mainpage
if request.method == 'POST':
NameError: name 'request' is not defined
但是我真的找不到我的错误.有人可以帮我吗?
But I really can't find my mistake. Can someone please help me with that?
from flask import Flask, Response
import requests
import hashlib
app = Flask(__name__)
salt = "UNIQUE_SALT"
default_name = 'test'
@app.route('/', methods=['GET', 'POST'])
def mainpage():
name = default_name
if request.method == 'POST':
name = request.form['name']
salted_name = salt + name
name_hash = hashlib.sha256(salted_name.encode()).hexdigest()
header = '<html><head><title>Identidock</title></head><body>'
body = '''<form method="POST">
Hallo <input type="text" name="name" value="{0}">
<input type="submit" value="Abschicken">
</form>
<p> Du siehst aus wie ein: </p>
<img src="/monster/{1}"/>
'''.format(name, name_hash)
footer = '</body></html>'
return header + body + footer
@app.route('/monster/<name>')
def get_identicon(name):
r = requests.get('http://dnmonster:8080/monster/' \
+ name + '?size=80')
image = r.content
return Response(image, mimetype='image/png')
if __name__ == '__main__':
app.run(debug=True, host='0.0.0.0')
推荐答案
您似乎忘记了导入flask.request 请求上下文 对象:
You appear to have forgotten to import the flask.request request context object:
from flask import request
