去项目目录配置
开发环境解决admin无css样式问题
vim entrypoint.sh
# 执行 collectstatic 收集静态文件
python manage.py collectstatic --noinput
vim settings.py
import os
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
vim urls.py
from django.contrib import admin
from django.urls import path
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
]
if settings.DEBUG:
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
生产环境
拷贝staticfiles目录到代理nginx，增加以下代理，修改setting.py中DEBUG = True的True为False
location /static/ {
root /usr/share/nginx/html/lbu_api/;
access_log off;
expires 30d;
}
------------------------------------------------
允许域名登录，不加登录admin后台报错

安装mysql及驱动
旧版本mysqlclient
pip install mysqlclient==2.1.1
新版本mysqlclien，安装容易失败
pip install mysqlclient -i https://mirrors.aliyun.com/pypi/simple/
或者安装pymysql
pip install pymysql
vim /data/lab_api/lab_django/lab_django/settings.py
import pymysql
pymysql.install_as_MySQLdb()
生产环境通常用Gunicorn来运行Django
pip install gunicorn
gunicorn --workers 4 --bind 0.0.0.0:8000 lab_django.wsgi:application
------------------------------------------------

创建合并代码app，git_operations
cd lab_django
python manage.py startapp git_operations
lab_web后端代码
安装paramiko库
pip install paramiko
将以下代码放到app目录git_operations/views.py
import paramiko
from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
import json
@csrf_exempt
def merge_branch(request):
if request.method == "POST":

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.close()

else:
return JsonResponse({"message": "No action needed for this platform."})
except json.JSONDecodeError:
return JsonResponse({"error": "Invalid JSON"}, status=400)
return JsonResponse({"error": "Invalid request method"}, status=405)
在git_operations/urls.py添加路由
from django.urls import path
from .views import merge_branch
urlpatterns = [
path("merge_branch/", merge_branch, name="merge_branch"),
]
在lab_django/lab_django/urls.py注册api/路由
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path("admin/", admin.site.urls),
path("api/", include("git_operations.urls")),
]
在lab_django/lab_django/settings.py注册git_operations
INSTALLED_APPS = [
...
"git_operations",
]
------------------------------------------------
curl请求测试
curl -X POST "http://10.10.10.2:8000/api/merge_branch/" -H "Content-Type: application/json" -d '{"platform": "lei", "source_branch": "develop", "target_branch": "master"}'
设置环境变量
export GITLAB_PRIVATE_TOKEN=osbxMgMpocGpChQkLxZL
echo $GITLAB_PRIVATE_TOKEN
------------------------------------------------
1.多个vue子页面
npm install vue-router
2.定义路由
vim ./src/router/index.js
import { createRouter, createWebHistory } from 'vue-router';
import Home from '../views/Home.vue';
import About from '../views/About.vue';
const routes = [
{ path: '/', component: Home }, // 主页
{ path: '/about', component: About }, // 关于页
];
const router = createRouter({
history: createWebHistory(),
routes,
});
export default router;
3.引入路由
vim src/main.js
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
const app = createApp(App);
app.use(router);
app.mount('#app');
4.App中配置
vim src/App.vue
<template>
<div id="app">
<nav>
<router-link to="/">首页</router-link> |
<router-link to="/about">关于</router-link>
</nav>
<router-view></router-view>
</div>
</template>
<style>
nav {
margin-bottom: 20px;
}
</style>
5.在src/views目录下建两个vue组件
src/views/Home.vue
<template>
<div>
<h1>首页</h1>
<p>欢迎来到首页！</p>
</div>
</template>
src/views/About.vue
<template>
<div>
<h1>关于我们</h1>
<p>这里是关于页面。</p>
</div>
</template>
------------------------------------------------
