## Overview
This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.  By using the [OpenAPI-spec](https://www.openapis.org/) from a remote server, you can easily generate an API client.

## Installation

Install the following dependencies:

```shell
go get github.com/stretchr/testify/assert
go get golang.org/x/oauth2
go get golang.org/x/net/context
```

Put the package under your project folder and add the following in import:

```golang
import sw "./{{packageName}}"
```

## Configuration of Server URL

Default configuration comes with `Servers` field that contains server objects as defined in the OpenAPI specification.

### Select Server Configuration

For using other server than the one defined on index 0 set context value `sw.ContextServerIndex` of type `int`.

```golang
ctx := context.WithValue(context.Background(), sw.ContextServerIndex, 1)
```

### Templated Server URL

Templated server URL is formatted using default variables from configuration or from context value `sw.ContextServerVariables` of type `map[string]string`.

```golang
ctx := context.WithValue(context.Background(), sw.ContextServerVariables, map[string]string{
	"basePath": "v2",
})
```

Note, enum values are always validated and all unused variables are silently ignored.

### URLs Configuration per Operation

Each operation can use different server URL defined using `OperationServers` map in the `Configuration`.
An operation is uniquely identifield by `"{classname}Service.{nickname}"` string.
Similar rules for overriding default operation server index and variables applies by using `sw.ContextOperationServerIndices` and `sw.ContextOperationServerVariables` context maps.

```
ctx := context.WithValue(context.Background(), sw.ContextOperationServerIndices, map[string]int{
	"{classname}Service.{nickname}": 2,
})
ctx = context.WithValue(context.Background(), sw.ContextOperationServerVariables, map[string]map[string]string{
	"{classname}Service.{nickname}": {
		"port": "8443",
	},
})
```

### {{{name}}}

{{#isApiKey}}
- **Type**: API key
- **API key parameter name**: {{{keyParamName}}}
- **Location**: {{#isKeyInQuery}}URL query string{{/isKeyInQuery}}{{#isKeyInHeader}}HTTP header{{/isKeyInHeader}}

Note, each API key must be added to a map of `map[string]APIKey` where the key is: {{keyParamName}} and passed in as the auth context for each request.

{{/isApiKey}}
{{#isBasic}}
{{#isBasicBasic}}
- **Type**: HTTP basic authentication

Example

```golang
auth := context.WithValue(context.Background(), sw.ContextBasicAuth, sw.BasicAuth{
    UserName: "username",
    Password: "password",
})
r, err := client.Service.Operation(auth, args)
```

{{/isBasicBasic}}
{{#isHttpSignature}}
- **Type**: HTTP signature authentication

Example

```golang
	authConfig := sw.HttpSignatureAuth{
		KeyId:                "my-key-id",
		PrivateKeyPath:       "rsa.pem",
		Passphrase:           "my-passphrase",
		SigningScheme:        sw.HttpSigningSchemeHs2019,
		SignedHeaders:        []string{
			sw.HttpSignatureParameterRequestTarget, // The special (request-target) parameter expresses the HTTP request target.
			sw.HttpSignatureParameterCreated,       // Time when request was signed, formatted as a Unix timestamp integer value.
			"Host",                                 // The Host request header specifies the domain name of the server, and optionally the TCP port number.
			"Date",                                 // The date and time at which the message was originated.
			"Content-Type",                         // The Media type of the body of the request.
			"Digest",                               // A cryptographic digest of the request body.
		},
		SigningAlgorithm:     sw.HttpSigningAlgorithmRsaPSS,
		SignatureMaxValidity: 5 * time.Minute,
	}
	var authCtx context.Context
	var err error
	if authCtx, err = authConfig.ContextWithValue(context.Background()); err != nil {
		// Process error
	}
	r, err = client.Service.Operation(auth, args)

```
{{/isHttpSignature}}
{{/isBasic}}
{{#isOAuth}}

- **Type**: OAuth
- **Flow**: {{{flow}}}
- **Authorization URL**: {{{authorizationUrl}}}
- **Scopes**: {{^scopes}}N/A{{/scopes}}
{{#scopes}} - **{{{scope}}}**: {{{description}}}
{{/scopes}}

Example

```golang
auth := context.WithValue(context.Background(), sw.ContextAccessToken, "ACCESSTOKENSTRING")
r, err := client.Service.Operation(auth, args)
```

Or via OAuth2 module to automatically refresh tokens and perform user authentication.

```golang
import "golang.org/x/oauth2"

/* Perform OAuth2 round trip request and obtain a token */

tokenSource := oauth2cfg.TokenSource(createContext(httpClient), &token)
auth := context.WithValue(oauth2.NoContext, sw.ContextOAuth2, tokenSource)
r, err := client.Service.Operation(auth, args)
```

## Documentation for Utility Methods

Due to the fact that model structure members are all pointers, this package contains
a number of utility functions to easily obtain pointers to values of basic types.
Each of these functions takes a value of the given basic type and returns a pointer to it:

* `PtrBool`
* `PtrInt`
* `PtrInt32`
* `PtrInt64`
* `PtrFloat`
* `PtrFloat32`
* `PtrFloat64`
* `PtrString`
* `PtrTime`
