1、背景

需要同步数据到 u8v13.0，调用 u8 api 的 csharp dll 接口。
由于u8版本较老，要使用 visual studio 2008 编写 X86 的 dll，python 也需要是 32 为的。
为了较为方便的部署到 Windows server 2008，python 版本选择为 python27-32位的。

2、环境准备

2.1、安装 mini-conda

下载地址： https://docs.conda.io/en/latest/miniconda.html

2.2、 配置 conda 镜像

conda config —add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config —add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config —add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config —add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/

  1. # 查看版本
  2. PS D:\devTools\Python\virtual_env> conda --version
  3. conda 4.11.0
  4. PS D:\devTools\Python\virtual_env>
  5. PS D:\devTools\Python\virtual_env>
  6. # 添加清华镜像
  7. PS D:\devTools\Python\virtual_env> conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  8. PS D:\devTools\Python\virtual_env> conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  9. PS D:\devTools\Python\virtual_env> conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
  10. PS D:\devTools\Python\virtual_env> conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
  11. PS D:\devTools\Python\virtual_env>

2.3、创建 32 位的 python27

2.3.1、 先切换环境到 32 位

命令：set CONDA_FORCE_32BIT=1

2.3.2、创建 32 位的 python27 env

conda create —name python27-32

4.3、添加自己的应用模块

命令：python project下的manage.py startapp appName

  1. ## 进入项目
  2. (python27-32) D:\OtherProjects\action\practice-demo-python\python27-32>cd u8_test
  4. (python27-32) D:\OtherProjects\action\practice-demo-python\python27-32\u8_test>python ./manage.py startapp u8-v1
  5. CommandError: 'u8-v1' is not a valid app name. Please use only numbers, letters and underscores.
  6. ## 报错，一样的应用名称也不能有中划线
  8. (python27-32) D:\OtherProjects\action\practice-demo-python\python27-32\u8_test>python ./manage.py startapp u8V1
  10. ## 查看目录层级结构
  11. (python27-32) D:\OtherProjects\action\practice-demo-python\python27-32\u8_test>tree /F
  12. Folder PATH listing
  13. Volume serial number is 34D6-1340
  14. D:.

4.4、编写自己的业务代码

步骤：

  1. 1. 编写 view
  2. 2. 创建路由
  3. 3. 加入模块路由到总路由
  4. 4. 注册自己的模块

4.4.1、编写 view

打开 views.py ，位置：u8_test\u8V1\views.py
