Question

我打算使用django创建一个类似app的dropbox。我可以实现将文件上传到服务器并在浏览器上显示。我希望用户能够下载或查看它。我正在尝试将其用于音频文件。我附上了views.py和index.html文件

from django.shortcuts import render
from django.http import HttpResponse
from django.shortcuts import render_to_response
from polls.models import Files
from os import walk
from os.path import isfile, join
def index(request):
        return render(request,"index.html", {})

def upload(request):
    for x in request.FILES.getlist("files"):
        def process(f):
            with open(r'C:\Users\rdoshi\storage\%s ' %f.name , 'wb+') as destination:
                b = Files(file_name= f.name)
                b.save()
                for chunk in f.chunks():
                    destination.write(chunk)
        process(x)
    q = Files.objects.all()
    return render(request,  "index.html", {'q' : q})
def play_file(request) : 
    file=Files.objects.get(id=37)
    fsock = open(r'C:\Users\rdoshi\storage\%s' %file.file_name, 'r')
    response = HttpResponse(fsock, content_type='audio/mpeg')
    return response

的index.html

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
  //$("#playlink").click(function(e){
    //  e.preventDefault();
      $.ajax({
            method: 'GET',
            url: '/polls/play_file',
            //data: {'id': 37},
            success: function (recvd_file) {
                 //this gets called when server returns an OK response
                 console.log("success");
                var asd = '<audio id="myaudio" src="recvd_file.mp3" preload="auto"></audio>';
                document.write(asd);
            },
        });
    });
</script>
<table id='filetable' border = '1'>
{% for i in q  %}
   <tr>
   <td>{{i.id}}</td>
   <td>
   {{i.file_name}}
   <button type="button" id='playlink' value = 'Download'>Download</button>
   </td>
   </tr>
 {% endfor %}
</table>
<form method = "post" action="../upload/" enctype ="multipart/form-data">{% csrf_token %}
         <input type="file" name="files" multiple />
         <input type = "submit" value="Upload" />
</form>

因此尝试播放该文件会给我这个错误

UnicodeDecodeError：＆＃39; charmap＆＃39;编解码器不能解码位置159中的字节0x90：字符映射到我假设问题是在views.py中使用fsock ...有人可以帮我这个吗？感谢

You are opening the file in read mode, but the file is a binary file. ( Notice that you also write the file in wb+ mode )

change

fsock = open(r'C:\Users\rdoshi\storage\%s' %file.file_name, 'r')

to

fsock = open(r'C:\Users\rdoshi\storage\%s' %file.file_name, 'rb')

Also, have a look at this so question上的多项更改，以设置Content-Type和Content-Length
