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:\WINDOWS\system32>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:\WINDOWS\system32>

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

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-----

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

重启防火墙

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
        }
    }
    # 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

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
