Keystone client
Introduction
The openapi folder is generated from keystone.yaml(i.e. the OAS) using openapi-generator-cli.
Another OAS token.json is not used for now because the openapi-generator-cli v5.3.0 does not support object combinations(oneOf, anyOf and allOf), in which case brings too much complexity.
The options parameter in some APIs is not supported.
Build
docker run --rm -v $(pwd)/keystone.yaml:/tmp/keystone.yaml -v $(pwd):/tmp/keystone openapitools/openapi-generator-cli generate -i /tmp/keystone.yaml -g go -o /tmp/keystone/openapi
rm -f ./openapi/go.mod ./openapi/go.sum
Note
For openapi-generator-cli does not support oneOf schema, define OneOfstringprojectResponse in model_project_get.go
type OneOfstringprojectResponse interface{}
Usage
// Build client
config := openapi.NewConfiguration()
client, err := keystone.NewClient(config)
if err != nil {
panic(err)
}
// Authenticate
domain := "default"
scope := model.NewDomainScope(&domain, nil)
user := "drone"
cred := model.NewPasswordCredential(nil, &user, "password", &domain, nil)
response, err := client.Auth.Authenticate(scope, cred)
if err != nil {
fmt.Printf("%v\n", response)
fmt.Printf("%v\n", err)
panic(err)
}
fmt.Println(client.Token)
// API Call
resp, r, err := client.DomainApi.ListDomain(context.TODO()).Execute()
How to change the server configuration?
Default
The client uses the first server (index=0) defined in OAS by default.
Change server index
By specifying the server index, client will use corresponding server configuration defined in OAS.
// Build the client
serverIndex := 1
config := openapi.NewConfiguration()
client, err := keystone.NewClientWithServerIndex(config, serverIndex)
// Authentication is omitted.
// API Call
ctx := context.WithValue(context.TODO(), openapi.ContextServerIndex, serverIndex)
resp, r, err := client.DomainApi.ListDomain(ctx).Execute()
Change manually in code
Just edit the config object.
config := openapi.NewConfiguration()
config.Servers = openapi.ServerConfigurations{{
URL: "localhost:8000",
Description: "local test",
Variables: nil,
}}
client, err := keystone.NewClient(config)
