Question

/ docs /中的TypeError不是JSON可序列化的

这是我的代码，导致了这个，

def schema_view(request):
  
        schema_view = get_swagger_view(title='Docs API')
        return Response(schema_view)

这是错误日志

PS：为什么stackoverflow不允许我发布这个，说它只是代码，请添加更多细节？我还应该添加什么？

我认为您使用Response中的restframework。 Response对象需要一个可序列化的对象作为数据。您正在传递一个视图作为参数，这是不可序列化的。您可以尝试传递字典：

def schema_view(request):

    schema_view = get_swagger_view(title='Docs API')
    dic_data = {'schema_view': schema_view}
    return Response(dic_data)

http://www.django-rest-framework.org/api-guide/responses/

TypeError函数SwaggerSchemaView不是JSON可序列化的
