requests请求django接口跨域问题处理

本文介绍: 是MIDDLEWARE_CLASSES 不是MIDDLEWARE，否则不生效。使用 httpx代替requests。

import httpx

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36",
}

res = httpx.get(url='https://www.baidu.com/', headers=headers, timeout=10, verify=False)
print(res.text)

django中添加如下配置：

INSTALLED_APPS = [

'corsheaders',

]

MIDDLEWARE_CLASSES = [

'corsheaders.middleware.CorsMiddleware', #这个放到第一位

]

注意：
是MIDDLEWARE_CLASSES 不是MIDDLEWARE，否则不生效。

如果处理后报如下错误：

ERRORS:
?: (admin.E408) 'django.contrib.auth.middleware.AuthenticationMiddleware' must be in MIDDLEWARE in order to use the admin application.
?: (admin.E409) 'django.contrib.messages.middleware.MessageMiddleware' must be in MIDDLEWARE in order to use the admin application.
?: (admin.E410) 'django.contrib.sessions.middleware.SessionMiddleware' must be in MIDDLEWARE in order to use the admin application.
        HINT: Insert 'django.contrib.sessions.middleware.SessionMiddleware' before 'django.contrib.auth.middleware.AuthenticationMiddleware'.

处理办法如下（同时添加MIDDLEWARE_CLASSES 和 MIDDLEWARE ）：

MIDDLEWARE_CLASSES = [
    'corsheaders.middleware.CorsMiddleware',
]

MIDDLEWARE = [
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
]
