django 基于form表单上传文件和基于ajax上传文件

一、基于form表单上传文件

1、html里是有一个input type="file" 和 ‘submit’的标签

2、vies.py

def fileupload(request):
    if request.method == ‘POST‘:
        print(request.POST)
        print(request.FILES)
        # from django.core.files.uploadedfile import InMemoryUploadedFile
        print(type(request.FILES.get(‘myfile‘)))
        myfile = request.FILES.get(‘myfile‘)
        name = myfile.name
        print(name)
        with open(name,‘wb‘) as f:
            # for line in myfile.chunks():
            #     f.write(line)
            for line in myfile:
                f.write(line)
        return HttpResponse(‘文件上传成功‘)

二、基于JSON上传文件

 $("#ajax_button").click(function () {
        var formdata=new FormData()
        formdata.append(‘name‘,$("#id_name2").val())
        formdata.append(‘myfile‘,$("#myfile")[0].files[0])
        $.ajax({
            url:‘‘,
            type:‘post‘,
            processData:false, //告诉jQuery不要去处理发送的数据
            contentType:false,// 告诉jQuery不要去设置Content-Type请求头
            data:formdata,
            success:function (data) {
                console.log(data)

            }

        })
    })

def fileupload(request):
    if request.method == ‘POST‘:
        print(request.POST)
        print(request.FILES)
        # from django.core.files.uploadedfile import InMemoryUploadedFile
        print(type(request.FILES.get(‘myfile‘)))
        myfile = request.FILES.get(‘myfile‘)
        name = myfile.name
        print(name)
        with open(name,‘wb‘) as f:
            # for line in myfile.chunks():
            #     f.write(line)
            for line in myfile:
                f.write(line)
        return HttpResponse(‘文件上传成功‘)

三、综上所述

　　基于form表单上传文件和基于ajax上传文件后端view界面一样的不需要改动，前台需呀改动
