home.html

<form action="" method="POST" enctype="multipart/form-data">
        {% csrf_token %}
        <input type="file" name = 'img' >
        <button type="submit"> Post On Facebook </button>
</form>

views.py

def home(request):
    if request.method == 'POST':
          # get the image absolute location 

    return render(request,'home.html')

我想要文件路径，这样我就可以使用graphapi将文件上传到facebook上。
