用Pycharm創建一個django項目。目錄如下：
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>upload</title> 6 </head> 7 <body> 8 {# 上傳文件的form表單必須要加上enctype="multipart/form-data" #} 9 <form action="/upload/" method="post" enctype="multipart/form-data"> 10 <input type="file" name="upload_files"> 11 <input type="submit" value="提交"> 12 </form> 13 </body> 14 </html>
1 from django.shortcuts import render,HttpResponse 2 3 # Create your views here. 4 5 # CBV方式（class base views） 6 from django.views import View 7 class Upload(View): 8 def post(self,request): 9 ''' 10 保存上傳文件前，數據需要存放在某個位置。默認當上傳文件小於2.5M時，django會將上傳文件的全部內容讀進內存。從內存讀取一次，寫磁盤一次。 11 但當上傳文件很大時，django會把上傳文件寫到臨時文件中，然后存放到系統臨時文件夾中。 12 :param request: 13 :return: 14 ''' 15 # 從請求的FILES中獲取上傳文件的文件名，file為頁面上type=files類型input的name屬性值 16 filename = request.FILES['upload_files'].name 17 # 在項目目錄下新建一個文件 18 with open(filename,'wb') as f: 19 # 從上傳的文件對象中一點一點讀 20 for chunk in request.FILES['upload_files'].chunks(): 21 # 寫入本地文件 22 f.write(chunk) 23 return HttpResponse('上傳ok') 24 25 def get(self,request): 26 return render(request, 'uploadFiles.html')

注意settings.py中的這一行要注釋掉
'django.middleware.csrf.CsrfViewMiddleware',
點擊運行，文件會上傳到項目的根目錄下面。
