使用flask实现一个简单的提交表单至后台操作
本文后台以阿里云接口为例，前台填写表单提交至后台提交到阿里云SLB白名单

#!/usr/bin/env python
#coding=utf-8

#pip3 install aliyun-python-sdk-core
#pip3 install aliyun-python-sdk-slb
import sys
import json
import requests
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkslb.request.v20140515.AddAccessControlListEntryRequest import AddAccessControlListEntryRequest

def AclEntrys2(IP, rogin):
    AclEntrys2 = [{'entry': IP + '/32', 'comment': rogin}]
    Acljson = json.dumps(AclEntrys2)
    return Acljson

def addslb(AclEntrys,AclId='acl-xxxxxxxx'):
    client = AcsClient('access', 'access-key', 'cn-shanghai')
    request = AddAccessControlListEntryRequest()
    request.set_accept_format('json')
    request.set_AclId(AclId)
    request.set_AclEntrys(AclEntrys)
    add = client.do_action(request)
    return add

if __name__=='__main__':
    add1 = AclEntrys2(sys.argv[1],sys.argv[2])
    add2 = addslb(add1)

此事例是提交两个变量 IP和备注信息实现操作
python需要安装

from flask import Flask, render_template, request
import als
import requests
app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/result', methods=['POST','GET'])
def result():
    if request.method == 'POST':
        IP=request.form.get('IP')
        rogin=request.form.get('rogin')
        test1=als.AclEntrys2(IP,rogin)
        addip1=als.addslb(test1)
        print (addip1)
        A = 'is not an ip address'
        B = 'The specified aclEntry already exists'
        a1 = A in str(addip1)
        a2 = B in str(addip1)
        if a1 == True:
            return 'IP格式不正确'
        elif a2 == True:
           return 'IP已存在'
        else:
            return 'IP已添加成功'
    else:
        return render_template('index.html')
if __name__ == '__main__':
    app.run(port=8808)

此脚本为flask接收表单操作
