我尝试使用Flask创建webapp;
dicrectory tree是这样的:
online_service:
----应用:
--------forms.py
--------的初始化的.py
--------模板:
------------的index.html
------------的login.html
--------views.py
----run.py
和: run.py:
import os
import sys
from app import app
app.config['SECRET_KEY'] = 'any string'
app.run(host='0.0.0.0', port = 8889)
views.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os
import sys
from flask import render_template, flash, redirect
from app import app
from .forms import LoginForm
file_dir = os.path.split(os.path.realpath(__file__))[0]
os.chdir(file_dir)
cur_dir = os.getcwd()
back_end_dir = os.path.join(cur_dir, "./../../back_end")
sys.path.append(back_end_dir)
import main
@app.route('/')
@app.route('/index')
def index():
return render_template("index.html",
title = 'Home')
def process(url):
url_status = "Invalid"
res = ""
res = main.get_life_stage(url)
url_str = "Url: " + url
url_status = "valid"
url_status_str = "Url_status: " + url_status
ret_str = "\n".join([url_str, url_status_str, res])
return ret_str
@app.route('/search', methods = ['GET', 'POST'])
def login():
form = LoginForm()
if form.validate_on_submit():
url = form.openid.data
ret_str = ""
ret = process(url)
flash(ret_str)
return redirect('/index')
return render_template('login.html',
title = 'Sign In',
form = form)
在views.py中,ret = process(url)处理来自前面的数据,然后返回一个字符串,ret = process(url)在单元测试中运行良好,但在视图中不起作用
那么,如何显示进程函数的返回字符串? 任何提示,我都会感激。 谢谢!
答案 0 :(得分:1)
我认为你应该分配给/**
* Throw TypeError when val is invalid
* @param {JOIN_TYPES} type
* @param {Class|Function} cls
* @param {*} val
* @param {Object} options
* @param {String} options.wrongJoinTypeErrorMessage
* @param {Boolean} options.nullable
*/
function validateJoinSet(type, cls, val, options) {
//...
}
* @param {Class|Function} cls
因为您使用ret_str
-
我希望您在ret_str = process(url)
