这是一种简单的做法 不需要用到数据库
setting.py中需要配置3个地方
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'upLoadImg', ] TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, "templates")], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] STATIC_URL = '/static/' STATICFILES_DIRS=[os.path.join(BASE_DIR,'static')] MEDIA_ROOT=os.path.join(BASE_DIR,'static/media')
urls.py
from django.contrib import admin from django.urls import path # from myImg.uploadPic import views from upLoadImg import views urlpatterns = [ path('admin/', admin.site.urls), path('uploadPic/',views.uploadPic), path('uploadHandle',views.uploadHandle) ]
views.py
from django.shortcuts import render from django.conf import settings from django.http import HttpRequest,HttpResponse import os # Create your views here. def uploadPic(request): return render(request,'myImg/uploadPic.html') def uploadHandle(request): if request.method == "POST": f1 = request.FILES['pic1'] fname = os.path.join(settings.MEDIA_ROOT,f1.name) with open(fname,'wb+') as pic: for c in f1.chunks(): pic.write(c) return HttpResponse('<img src="/static/media/%s" width="500" height="500" alt="图片无法显示"/>'%f1.name) # 这里不给width和height会按图片本身分辨率显示 else: return HttpResponse("error") #下面这个是直接显示路径 # pic1 = request.FILES['pic1'] # picName=os.path.join(settings.MEDIA_ROOT,pic1.name) # return HttpResponse(picName)#/Users/liuwei/myImg/static/media/6.png #file:///Users/liuwei/myImg/static/media/6.png
upLoadPic.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form action="/uploadHandle" method="post" enctype="multipart/form-data"> {% csrf_token %} <input type="file" name="pic1"> <br> <input type="submit" value="上传"> </form> </body> </html>
那进入myImg/目录 运行
python3 manage.py runserver
在浏览器打开
http://127.0.0.1:8000/uploadPic/
碰到几个问题：
1. 图片显示不了 那是因为setting .py中没有
STATICFILES_DIRS=[os.path.join(BASE_DIR,'static')]
2.上传不了 是因为 要用wb+ ， 这个百度就可以了
with open(fname,'wb+') as pic:
