Django简单上传文件例子

from django.conf.urls import url
from app01 import views

urlpatterns = [
    url(r‘^upload/‘, views.upload),

]

<form action="" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    <input type="file" name="file">
    <input type="submit">
</form>

import os
from django.conf import settings
def upload(request):
    if request.method == "POST":
        filename = request.FILES["file"].name
        #判断名字是否存在
        if os.path.exists(os.path.join(settings.BASE_DIR, filename)):
            #假设文件后缀和文件名以"."区分
            name, suffix = filename.split(".")
            #存在同名文件处理方法
            name += "1"
            filename = name + "." +suffix
        with open(filename, "ab") as f:
            #chunks() 可以指定每次读取的具体大小
            for chunk in request.FILES["file"].chunks():
                f.write(chunk)
        return HttpResponse("OK")
    return render(request, "file.html")
