用户头像上传及缩略图

Posted 2020-10-04 chandb

实现用户在客户端更改头像，上传头像图片，自动生成缩略图显示。

前端代码：注意  enctype="multipart/form-data"

<form enctype="multipart/form-data" method="POST" action="{% url \'users:avatar_upload\'%}">{% csrf_token %}

            <input type="file" name="image"/>
            <div class="modal-body">
                <div class="cutimgbox">
                    <div class="btn-box-cutimg">
                        <input type="submit" class="btn btn-xxlg btn-micv5 btn-block" value="submit" />
                    </div>
                </div>
            </div>
        </form>

前端效果：

#视图函数修改头像

 

from PIL import Image
@login_required
# @csrf_exempt
def avatar_upload(request):
    if request.method == \'POST\':
        username = request.user.username
        user = UserProfile.objects.get(username=username)
        if \'image\' in request.FILES:
            image = request.FILES[\'image\']
 
            #缩略图
            s_img = Image.open(image)
            s_img.thumbnail((80, 80), Image.ANTIALIAS)
            if not os.path.exists(mini_img_path):
                os.makedirs(mini_img_path)
            img_url = mini_img_path + \'\\\\\' + username+ ".jpeg"
            s_img.save(img_url )
            user.avatar_small_thumbnall= r\'\\uploads\\avatar\\minipic\'+\'\\\\\' +username+ ".jpeg"
            user.save()
    return render(request,\'users/userinfo.html\',locals())
