django跨域问题解决

在django中，访问非同源网站（协议，域名，端口号）时，会出现：

 

解决方案：

1.安装 django-cors-headers

pip install django-cors-headers

2.修改 setting.py

INSTALLED_APPS = [
    ...
    'corsheaders'，
    ...
 ] 

# 添加中间件
MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',# 默认
    'django.contrib.sessions.middleware.SessionMiddleware', # 默认

    'corsheaders.middleware.CorsMiddleware',# 默认
    # 注意顺序，即在上一个的下面
    'django.middleware.common.CommonMiddleware', # 新增 ✔

    'django.middleware.csrf.CsrfViewMiddleware',# 默认
    'django.contrib.auth.middleware.AuthenticationMiddleware',# 默认
    'django.contrib.messages.middleware.MessageMiddleware', # 默认
    'django.middleware.clickjacking.XFrameOptionsMiddleware',# 默认
    'django.middleware.common.CommonMiddleware',# 默认
]

# 跨域增加忽略
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_ALLOW_ALL = True
CORS_ORIGIN_WHITELIST = (
    '*'
)
CORS_ALLOW_METHODS = (
    'DELETE',
    'GET',
    'OPTIONS',
    'PATCH',
    'POST',
    'PUT',
    'VIEW',
)
CORS_ALLOW_HEADERS = (
    'XMLHttpRequest',
    'X_FILENAME',
    'accept-encoding',
    'authorization',
    'content-type',
    'dnt',
    'origin',
    'user-agent',
    'x-csrftoken',
    'x-requested-with',
)

然后再次运行：

 

 xxx.html

<!DOCTYPE html>
<html>

    <head>
        <meta charset="UTF-8">
        <title></title>
    </head>
    <script src="js/jquery-1.7.2.js"></script>
    <script type="text/javascript">
        function upd() {
            $.ajax({
                type: "GET",
                data: "a=1",
                url: "http://127.0.0.1:8000/books/?format=json",
                success: function(result) {
                    console.log(result);
                    //alert(result)
                }
            });
        }
    </script>
    <body>
        <!--获取-->
        <button id="btn2" onclick="upd()">Get request 获取</button>
    </body>

</html>
