第四百零三节,python网站在线支付,支付宝接口集成与远程调试,
windows系统安装Python虚拟环境
首先保证你的系统已经安装好了Python
安装virtualenv
C:WINDOWSsystem32>pip3 install virtualenv Collecting virtualenv Downloading virtualenv-15.1.0-py2.py3-none-any.whl (1.8MB) 100% |████████████████████████████████| 1.8MB 110kB/s Installing collected packages: virtualenv Successfully installed virtualenv-15.1.0 C:WINDOWSsystem32>
安装virtualenvwrapper
virtualenvwrapper是virtualenv的一个方便管理虚拟环境的管理器
pip3 install virtualenvwrapper
指定虚拟环境,保存路径
首先在要保存虚拟环境的地方创建一个Evns目录,然后将这个目录添加到系统环境变量,以后创建的虚拟环境就会保存在这个目录,重启系统后生效
创建虚拟环境,创建后会自动进入虚拟环境
mkvirtualenv 虚拟环境名称
[root@192 xu_ni_huan_jing]# mkvirtualenv jxiou Using base prefix '/usr/local' New python executable in /usr/xu_ni_huan_jing/jxiou/bin/python3.5 Also creating executable in /usr/xu_ni_huan_jing/jxiou/bin/python Installing setuptools, pip, wheel...done. virtualenvwrapper.user_scripts creating /usr/xu_ni_huan_jing/jxiou/bin/predeactivate virtualenvwrapper.user_scripts creating /usr/xu_ni_huan_jing/jxiou/bin/postdeactivate virtualenvwrapper.user_scripts creating /usr/xu_ni_huan_jing/jxiou/bin/preactivate virtualenvwrapper.user_scripts creating /usr/xu_ni_huan_jing/jxiou/bin/postactivate virtualenvwrapper.user_scripts creating /usr/xu_ni_huan_jing/jxiou/bin/get_env_details (jxiou) [root@192 xu_ni_huan_jing]#
5.退出虚拟环境
deactivate
(jxiou) [root@192 xu_ni_huan_jing]# deactivate [root@192 xu_ni_huan_jing]#
6.查看有哪些虚拟环境
workon
[root@192 /]# workon jxiou2 jxiou [root@192 /]#
7.进入一个指定的虚拟环境
workon jxiou(虚拟环境名称)
[root@192 /]# workon jxiou (jxiou) [root@192 /]#
8.虚拟环境创建好后,创建Django项目,创建好数据库,开始本地调试支付请求
支付宝接口集成 ,本地环境调试支付请求
1。首先登录 蚂蚁金服网站,也就是支付宝开发者平台
登录蚂蚁金服开发者平台后,创建沙箱应用
也就是支付宝给开发者提供的调试环境应用
注意这里我们一定选择RSA2(SHA256)密钥(推荐),这个是比较安全的方式,
2.我们设置应用公钥
设置公钥,访问https://docs.open.alipay.com/291/105971/ 这个网址
下载生成公钥的工具
下载解压后
生成公钥
生成公钥后会得到两个文件
注意:这两个文件很重要一定要保存好
生成公钥后,将公钥填写到信息配置里
当我们填写好公钥保存后,会自动给我们生成支付宝公钥
将生成的支付宝公钥,复制下载写在一个TXT文件里
这样我们就有了3个秘钥
将3个秘钥修改成英文或者拼音名称后,放到网站项目中
在秘钥txt文件里,秘钥内容的头部和结尾加上两行字符串,注意所有秘钥都要加
-----BEGIN PRIVATE KEY-----
秘钥内容....
-----END PRIVATE KEY-----
3.支付宝,支付集成代码

4.生成支付URL后,我们用这个URL模拟支付一下
注意:沙箱环境,支付的时候要用沙箱账号里提供的支付账号才可以支付
支付成功后已经,跳转到我们设置的同步处理页面
5.支付宝支付成功后通知接口验证

远程测试支付成功后返回服务器验证
首先准备一台服务器,将开发环境和项目同步到服务器上,并且在服务器上配置好python虚拟环境和所需python插件包
项目同步到服务器上,也就是将本地项目,上传到服务器进行同步
配置服务器信息
2
上传项目
数据上传后,在服务器配置数据库访问权限,和配置python环境
配置远程调试
1,在阿里云后台,开放8000端口
2,在服务器开发8000端口
vim /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT #添加配置项 -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 8000 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT
重启防火墙
service iptables restart
设置当前,使用的数据库用户,可以任意ip访问
让数据库用户可以从外部登陆和本地登陆
1
grant all privileges(除授权外的所有权限) on *.*(表示所有数据库的所有表) to 'test_user(授权的用户名)'@'localhost(授权ip)' identified by 'test_user(用户密码)';
grant all privileges on *.* to 'test_user'@'localhost' identified by 'test_user';
2
grant all privileges(除授权外的所有权限) on *.*(表示所有数据库的所有表) to 'test_user(授权的用户名)'@'%(所有ip)' identified by 'test_user(用户密码)';
grant all privileges on *.* to 'test_user'@'%' identified by 'test_user';
配置项目的settings.py文件
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', #配置数据库引擎名称 'NAME': 'jxiou', #数据库名称 'USER': 'test_user', #数据库用户名 'PASSWORD': 'test_user', #数据库密码 'HOST': '47.52.39.160', #数据库链接地址,为服务器ip 'PORT': '3306', #数据库端口 } }
2
# SECURITY WARNING: don't run with debug turned on in production! DEBUG = True ALLOWED_HOSTS = ['*'] # 允许任意ip访问项目
开始远程调试
2
3
4
5
此时,就可以用服务器ip加8000端口,访问服务器网站了
前面,我们在本地调试了支付宝支付请求,这下我们要调试,支付宝支付成功后向我们服务器返回请求我们要验证返回的请求,,所以需要将远程服务器启动来,接收支付宝的返回
