Webitel HTTP OpenAPI Client for Go

This HTTP Go client for Webitel is generated from Webitel's OpenAPI specification using swagger for Go.

Generate the client

Once bingo & swagger are installed (see Dependencies), generate the client for all Webitel APIs, with the following make command:

make generate-client

This runs the Swagger generation command.

To generate the client for a specific Webitel API, find the name of its tag and model in the Webitel OpenAPI specification. Then, set those as environment variables and run the command to generate it:

export API_TAG=CalendarService
export MODEL=engineCalendar
make generate-client

How to use custom templates

In order to generate the client, go-swagger uses default templates. These templates can be customised to add custom configuration that are applied each time the client is generated.

For more information, check out the go-swagger docs on how to use custom templates. The default template definitions for the client can be found in go-swagger/generator/templates/client/.

In this project, the custom templates can be found in templates/. They are provided to the generation command through the flag --template-dir=templates.

The custom templates provide added functionality for things such as authentication, TLS/SSL, retries, and custom error handling.

Build the client

Configuration

The client has the following friendly configuration options:

import goapi "github.com/webitel/webitel-openapi-client-go/client"

cfg := &goapi.TransportConfig{
    // Host is the doman name or IP address of the host that serves the API.
    Host:       "dev.webitel.com",
    
    // BasePath is the URL prefix for all API paths, relative to the host root.
    BasePath:   "/api",
    
    // Schemes are the transfer protocols used by the API (http or https).
    Schemes:    []string{"http"},
    
    // APIKey is an optional API key or service account token.
    APIKey:     os.Getenv("WEBITEL_ACCESS_TOKEN"),
    
    // TLSConfig provides an optional configuration for a TLS client
    TLSConfig:  &tls.Config{},
    
    // NumRetries contains the optional number of attempted retries
    NumRetries: 3,
    
    // RetryTimeout sets an optional time to wait before retrying a request
    RetryTimeout: 0,
    
    // RetryStatusCodes contains the optional list of status codes to retry
    // Use "x" as a wildcard for a single digit (default: [429, 5xx])
    RetryStatusCodes: []string{"420", "5xx"},
    
    // HTTPHeaders contains an optional map of HTTP headers to add to each request
    HTTPHeaders: map[string]string{},
}

client := goapi.NewHTTPClientWithConfig(strfmt.Default, cfg)
