django - 跨域请求

想要在django里面跨域的话，首先得有一个更换域名的操作

首先先进入

hosts文件里面 

最后的三个是要改的域名 

想要在网站访问的时候没有端口号只有域名的话

运行的时候 python manage.py runserver 80

加个80 就可以了

跨域操作的时候还得再setting文件里配置一下

#配置可跨域范围
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_ALLOW_ALL = True

然后再INSTALLED_APPS里面添加跨域

INSTALLED_APPS = [
    \'django.contrib.admin\',
    \'django.contrib.auth\',
    \'django.contrib.contenttypes\',
    \'django.contrib.sessions\',
    \'django.contrib.messages\',
    \'django.contrib.staticfiles\',
    \'mymac\',
    \'myapp\',
    \'myapp1\',
    #跨域
    \'corsheaders\',
    #异步
    \'djcelery\'
]   

MIDDLEWARE = [
    \'django.middleware.security.SecurityMiddleware\',
    \'django.contrib.sessions.middleware.SessionMiddleware\',
    #定义跨域中间件
    \'corsheaders.middleware.CorsMiddleware\',
    \'django.middleware.common.CommonMiddleware\',
    #\'django.middleware.csrf.CsrfViewMiddleware\',
    \'django.contrib.auth.middleware.AuthenticationMiddleware\',
    \'django.contrib.messages.middleware.MessageMiddleware\',
    \'django.middleware.clickjacking.XFrameOptionsMiddleware\',
]

然后再中间件里添加个跨域中间件就行了

这样就可以跨域访问啦
