【问题描述】:
所以我使用 Chrome,Django 版本 1.9.6,python 2.7.13。
我正在尝试将原始数据(音频文件)从 html/js 发送到 django 服务器以从 .mp3 转换为 .wav 格式。
但是,它甚至无法访问未设置 CSRF cookie 的 views.py。错误。
我已经尝试了几乎所有可以在网上找到的东西。
我有以下views.py和index.html。
index.html

obfuscateButton.innerHTML = "Proccessing...";
var xhr = new XMLHttpRequest();

var method = 'POST';
xhr.onreadystatechange = function() {

xhr.open(method, url, true);
xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
var formData = new FormData();

xhr.send(formData);

view.py
from django.http import HttpResponse
from django.shortcuts import render
from django.views.decorators.csrf import ensure_csrf_cookie
from subprocess import call
from django.core.files import File
from .forms import UploadFileForm
from django.views.decorators.csrf import csrf_exempt
import subprocess
def index(request):
return render(request, 'obfuscator/index.html')
#@csrf_exempt
def obfuscate(request):
print("HI")
if request.method == 'GET':
return HttpResponse("Hi")
if request.method == 'POST':
print("files: " + str(request.FILES))
print("posts: " + str(request.POST))
if len(request.POST) > 0:
handle_uploaded_file(request.FILES['audio_file'])
return HttpResponse("The form was valid!")
def handle_uploaded_file(f):
with open('temp.mp3', 'wb+') as destination:
for chunk in f.chunks():
destination.write(chunk)
subprocess.check_call("ffmpeg -y -i temp.mp3 temp.wav", shell=True)
我真的不知道为什么这在我的计算机 (mac OS X) 上不起作用。 每次它给我(CSRF cookie not sets)错误,而不是(CSRF token 丢失或不正确。)错误。
我可以将它与 csrf_exempt 一起使用,但我想将它与 csrf 保护一起使用。
请帮忙!
谢谢。
