目標：利用django實現上傳檔案功能
1，先設定路由系統
urls.py
from django.conf.urls import url,includefrom django.contrib import adminfrom app01 import viewsurlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘^upload/$‘, views.upload),]
2，配置html模板檔案(前端頁面展示)
templates/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"> <p><input type="file" name="f1"></p> <p><input type="text" name="hostname"></p> <input type="submit" value="upload"></form></body></html>
3,開始寫上傳邏輯
views.py
#_*_ coding:utf-8 -*-
from django.shortcuts import render,HttpResponse
from django.views.generic.list import ListView
def index(request):
return HttpResponse("haha")
def upload(request):
if request.method == "POST": #判斷接收的值是否為POST
inp_files = request.FILES #上傳檔案的接收方式應該是request.FILES
file_obj = inp_files.get(‘f1‘) #通過get方法擷取upload.html頁面提交過來的檔案
f = open(file_obj.name,‘wb‘) #將用戶端上傳的檔案儲存在伺服器上，一定要用wb二進位方式寫入，否則檔案會亂碼
for line in file_obj.chunks(): #通過chunks分區上傳儲存在伺服器記憶體中,以64k為一組，迴圈寫入到伺服器中
f.write(line)
f.close()
return render(request,‘upload.html‘) #將處理好的結果通過render方式傳給upload.html進行渲染
4,上傳功能全部完成，比較簡單，我們來進行驗證
上傳本地一個png的圖片，然後點擊upload提交
點擊提交後，在伺服器上看到了剛剛上傳的檔案“django流程圖”
通過Django實現分區上傳檔案成功。
