第3章 Django中的Template模板

3-10 可选观看：项目练习模板引擎

1.在项目 simple_api_server_test 下，新建目录 templates

2.在项目 simple_api_server_test 下目录 simple_api_server_test，修改文件 settings.py，添加模板路径

#添加模板路径
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

3.在项目 simple_api_server_test 下目录 templates，添加文件 music.html、movie.html、book.html

]

        if response.status_code != 200:
            return JsonResponse({'errcode':-1, 'errmsg':'请求豆瓣异常'})
