1：python之上傳文件
1.1.url代碼
"""untitled1222 URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.1/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
from app01 import views
urlpatterns = [
path('admin/', admin.site.urls),
path('upload/',views.upload),
]
1.2.views代碼
from django.shortcuts import render
from django.shortcuts import HttpResponse
# Create your views here.
def upload(request):
if request.method=='GET':
return render(request,'upload.html')
else:
user=request.POST.get('user')
print(user)
#img是一個對象，包含文件名，文件大小、內容....
img=request.FILES.get('img')
print(img)
print(img.name)
print(img.size)
#上傳到本地服務器
f=open(img.name,'wb')
for line in img.chunks():
f.write(line)
f.close()
return HttpResponse('OK')
1.3.templates中upload.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="/upload/" method="post" enctype="multipart/form-data">
<input type="text" name="user">
<input type="file" name="img">
<input type="submit" value="提交">
</form>
</body>
</html>
1.4.效果顯示
2.上傳文件按鈕優化
2.1按鈕優化只需在原有upload.html文件中進行相關樣式設置即可，重點設置透明度：opacity:0
1
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="/upload/" method="post" enctype="multipart/form-data">
<input type="text" name="user">
<div style="position: relative;">
<a>上傳</a>
<input type="file" name="img" style="opacity: 0.2;position:absolute; top:0;left: 0;">
</div>
<input type="submit" value="提交">
</form>
<script src="/static/jquery-3.3.1.min.js"></script>
</body>
</html>
2.2.優化後的效果顯示：
3.python之Form組件文件上傳（與上述自定義上傳文件的區別在：form上傳文件多了驗證功能）

2 from django.shortcuts import HttpResponse

22 f = open(img.name, 'wb')
