如何使用flask_restplus定义字典字段,以在使用swagger代码生成的go代码中使用?

I have used swagger CLI to generate go code to call my flask app. swagger codegen converts fields.Raw type defined with flask_restplus model to *interface{} in go

assigning the value to the field with *interface{} type in go returns back

prog.go:18:26: cannot use notebook_spec_secrets (type map[string]string) as type *interface {} in assignment: *interface {} is pointer to interface, not interface

You can test it here https://play.golang.org/p/sFE9Qr-72_G

A quick and dirty fix will be changing the generated code by swagger cli and change

NotebookSpec *interface{}

to

NotebookSpec interface{}

  1. Is it possible to cast dictionary to *interface{} in go? (my google search shows a pointer to the interface in go is invalid and logically is not correct )

  2. How to define a dictionary field with flask-restplus

run_definition = api.model('Run definition',
                           {

                               'notebook_spec_secrets':
                               fields.Raw(required=False,
                                          example={
                                              "eventhub_source_cs": "Endpoint=sb://xxxx.servicebus.windows.net/;SharedAccessKeyName=xxxx;SharedAccessKey=xxxx=;EntityPath=sourceeh",
                                              "eventhub_destination_cs": "Endpoint=sb://xxxx.servicebus.windows.net/;SharedAccessKeyName=xxxx;SharedAccessKey=xxxx=;EntityPath=desteh",
                                              "adl2_destination_oauth2_clientid": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
                                              "adl2_destination_oauth2_clientsecret": "xxxx=",
                                              "adl2_destination_oauth2_tenantid": "xxxx=",
                                              "adl2_destination_cs": "abfss://<file-system-name>@<storage-account-name>.dfs.core.windows.net/folder1",
                                          })})

    I'm not sure why it generates a pointer to an interface, but can still assign to it by explicitly casting your map to interface{} and then taking the address of that:

    notebook_spec_secrets := map[string]string{
        "eventhub_source_cs":                   "1",
        "eventhub_destination_cs":              "2",
        "adl2_destination_oauth2_clientid":     "3",
        "adl2_destination_oauth2_clientsecret": "4",
        "adl2_destination_oauth2_tenantid":     "5",
        "adl2_destination_cs":                  "6",
    }
    
    var nssi interface{} = notebook_spec_secrets
    definition.NotebookSpec = &nssi
