Form表单上传文件

 

文件和其他的数据类型不一样，是一个二进制的形式
Form上传文件的时候切记要加上：enctype="multipart/form-data"

formupload.html

<form action="/formupload/" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    <p>姓名：<input type="text" name="username"></p>
    <p>密码：<input type="password" name="password"></p>
    <p>头像：<input type="file" name="file"></p>
    <p><input type="submit" value="提交"></p>
</form>

view.py

def formupload(request):
    if request.method == "POST":
        username = request.POST.get("username")
        password = request.POST.get("password")
        # file = request.FILES   #拿到的是一个句柄
        file_obj = request.FILES.get("file")
        print(file_obj,file_obj.name)
        print(type(file_obj),type(file_obj.name))   #<class 'django.core.files.uploadedfile.InMemoryUploadedFile'>   <class 'str'>
        with open(file_obj.name,"wb") as f:
            for i in file_obj:
                f.write(i)
        return HttpResponse("上传成功...")
    return render(request,"formupload.html")
