开发一个文件下载功能,在页面上点下载按钮,可以下载一个文件,如excel,word,pdf等
前端页面写一个a标签,href地址对应接口下载接口地址:/downpdf
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>down file</title> </head> <body> <h3>下载文件功能开发</h3> <a href="/downpdf">点我下载</a> </body> </html>
待下载的文件放到static目录,如:python1.pdf
下载文件使用FileResponse,添加返回头部参数Content-Type和Content-Disposition
from MyDjango.settings import BASE_DIR from django.views import View from django.http import FileResponse, HttpResponse import os # 作者-上海悠悠 QQ交流群:717225969 # blog地址 https://www.cnblogs.com/yoyoketang/ class DownPage(View): def get(self, request): """访问web页面""" return render(request, 'downfile.html') class DownPDF(View): def get(self, request): """下载pdf接口""" # 文件路径 file_path = os.path.join(BASE_DIR, 'static', "python1.pdf") print("11111111111111111111111") print(file_path) file = open(file_path, 'rb') response = FileResponse(file) response['Content-Type'] = 'application/octet-stream' response['Content-Disposition'] = 'attachment;filename="python1.pdf"' return response
urls.py设置网页访问地址和文件下载地址
urlpatterns = [ url('^down$', views.DownPage.as_view()), url('^downpdf$', views.DownPDF.as_view()) ]
web页面访问
点击下载效果
在浏览器直接访问下载地址http://localhost:8000/downpdf
也可以下载
