jdango 基于form与ajax发送文件

Views

# form表单文件上传
def file_put(request):
    print('------',request.FILES)
    if request.method == 'POST':
        file_obj = request.FILES.get('file')
        with open(file_obj.name,'wb') as f:
            for line in file_obj:
                f.write(line)
        return HttpResponse('ok')
    return render(request,'file.html')



# 基于ajax文件上传
def ajax_put_file(request):

    if request.method =='POST':
        file_obj = request.FILES.get('avator')
        with open(file_obj.name, 'wb') as f:
            for line in file_obj:
                f.write(line)
        return HttpResponse('OK')
    return render(request,'file.html')

HTML中

 <form action="" method="post" enctype="multipart/form-data">
        {% csrf_token %}
        用户名<input type="text" name="user" id="user">
        头像<input type="file" name="file">
        <input type="submit">
    </form>

    --------------<hr>------------


    用户名<input type="text"  id="user_aj">
    头像<input type="file"  id="avator">
    <input type="button" id="btn_aj" value="ajax提交">

　　

jquery

<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script> 

$('#btn_aj').click(function () {
        var formdata = new FormData();
        formdata.append('user',$('#user_aj').val());
        formdata.append('avator',$('#avator')[0].files[0]);

        $.ajax({
            url:'/ajax_put_file/',
            type:'post',
            data:formdata,
            contentType:false,
            processData:false,
            success:function (data) {
                console.log(data)
            }
        })
