【问题描述】：

我正在尝试使用 Django 和 Vue.js 制作聊天应用程序。为此，我开始创建一个 Django 项目，在其中使用 pip 安装了 Django REST 框架和 djoser，并在 urls.py 中添加了相应的 url。

但是当我尝试使用 [curl -X POST http://127.0.0.1:8000/auth/users/create/ --data] 创建用户时，我得到的是 "curl: ( 7) 无法连接到 127.0.0.1 端口 8000：连接被拒绝”。以下是所需的脚本。

urls.py：

    """chatire URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/3.1/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))

【问题讨论】：

你如何运行你的项目？ Connection Refused 错误表明没有进程正在侦听该端口。

使用下面的命令我正在运行项目-python manage.py runserver，我运行它时没有收到错误，但是当我运行它时----> curl -X POST @ 987654321@ --data ，我收到了这个错误

你确定 Django 正在监听那个端口吗？如果您使用的是 Linux，请尝试 sudo netstat -ntlp 并查看您的应用使用的端口。

没有端口不在监听。我已经使用 netstat -a 进行了检查。顺便说一句，我正在使用Windows。我在项目中使用 8000 端口，但是当使用 netstat 命令检查时，我无法找到 8000 端口监听。

嗯，你是使用 WSL 来运行 django 还是 curl？

【参考方案1】：

打开 settings.py 文件并进行这些更改

DEBUG = False
 
ALLOWED_HOSTS = ['*']
