我有一个python脚本main.py,它接受两个参数(2个文本文件)
我使用的是MAC OS X. Python 2.7
这可以在终端上轻松运行:
python main.py train.txt sample.txt
我现在使用带有非常小的HTML的Flask开发了一个小型前端,如下所示:
#front.py FLASK
from flask import Flask, render_template, request, redirect
app = Flask(__name__)
@app.route('/')
def hello_world():
return render_template('index.html')
@app.route('/signup', methods = ['POST'])
def signup():
email = request.form['email']
email1 = request.form['email1']
# command below is just for testing, I wish to implement the same as this would if this would be typed in terminal.
print("main.py " + email + " " + email1)
return redirect('/')
if __name__ == "__main__":
app.run()
和HTML
<!DOCTYPE html>
<html>
<head>
<title>T</title>
</head>
<body>
<form action="/signup" method="post">
<input type="text" name="email"></input>
<input type="text" name="email1"></input>
<input type="submit" value="Signup"></input>
</form>
</body>
</html>
这个HTML代码只是使用一个表单来接受2个参数(我发现这比JS更容易,因为我没有经验)。
我刚刚写了
print("main.py " + email + " " + email1)
以上命令进行测试,现在它没有任何实用程序。
参数的使用:
#main.py
from filter import Filter
import sys
# Get arguments from user
train = sys.argv[1]
messages = sys.argv[2]
# Open files for reading and writing
train_file = open(train, "rb")
messages_file = open(messages, "rb")
predictions_file = open("predictions.txt", "w")
# Create new filter and train it using the train-file
f = Filter()
f.train(train_file)
#filter the messages in messages_file, write results to predictions_file
f.filter(messages_file, predictions_file)
# Close all the files
train_file.close()
messages_file.close()
predictions_file.close()
我现在想通过这个烧瓶应用程序本身运行我的脚本main.py,并想知道这是怎么回事。
我正在使用import main和另一个app decorator说/ exec并手动将URL更改为127.0.0.2000到127.0.0.2000/exec但这是错误,因为main需要传递参数。
很抱歉,如果我在解释问题时不清楚,请告诉我是否可以更好地解释任何问题,以帮助您解决问题。
谢谢

您需要稍微修改此脚本。您应该像在Flask应用程序中那样将处理输入的所有代码放在name == '__main__'
块中,其余部分放在您从该块调用的函数中:
def do_stuff(train, messages):
# Open files for reading and writing
train_file = open(train, "rb")
...
predictions_file.close()
if __name__ == '__main__':
# Get arguments from user
train = sys.argv[1]
messages = sys.argv[2]
do_stuff(train, messages)
现在,您的Flask应用可以拨打main.do_stuff(email, email1)
。
