    添加网页api接口文档
    mytool/urls.py

    #新增
from rest_framework.documentation import include_docs_urls
urlpatterns = [
    re_path(r'^', include(router.urls)),
    re_path(r'^doc/',include_docs_urls(title="接口文档")),
    path('admin/', admin.site.urls),
]

    然后访问http://60.1.1.28:8888/doc/会报错,需要安装coreapi

    pip install coreapi

    再次访问http://60.1.1.28:8888/doc/还是报错AttributeError: ‘AutoSchema’ object has no attribute ‘get_link’
    mytool/setting.py新增

    #新增
REST_FRAMEWORK = {
    'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema'
}

    再次访问http://60.1.1.28:8888/doc/,就没问题了.
