# Go API client for {{packageName}}
{{#appDescriptionWithNewLines}}
{{{appDescriptionWithNewLines}}}
{{/appDescriptionWithNewLines}}
## 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.
- API version: {{appVersion}}
- Package version: {{packageVersion}}
{{^hideGenerationTimestamp}}
- Build date: {{generatedDate}}
{{/hideGenerationTimestamp}}
- Build package: {{generatorClass}}
{{#infoUrl}}
For more information, please visit [{{{infoUrl}}}]({{{infoUrl}}})
{{/infoUrl}}
## 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 {{packageName}} "{{gitHost}}/{{gitUserId}}/{{gitRepoId}}{{#isGoSubmodule}}/{{packageName}}{{/isGoSubmodule}}"
```
To use a proxy, set the environment variable `HTTP_PROXY`:
```golang
os.Setenv("HTTP_PROXY", "http://proxy_name:proxy_port")
```
## 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(), {{packageName}}.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(), {{packageName}}.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(), {{packageName}}.ContextOperationServerIndices, map[string]int{
"{classname}Service.{nickname}": 2,
})
ctx = context.WithValue(context.Background(), {{packageName}}.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}}
{{#isBasicBearer}}
- **Type**: HTTP Bearer token authentication
Example
```golang
auth := context.WithValue(context.Background(), sw.ContextAccessToken, "BEARER_TOKEN_STRING")
r, err := client.Service.Operation(auth, args)
```
{{/isBasicBearer}}
{{#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 := client.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)
```
{{/isOAuth}}
{{/authMethods}}
## 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`

## Methods
{{^vendorExtensions.x-is-one-of-interface}}
### New{{classname}}
`func New{{classname}}({{#vars}}{{#required}}{{nameInCamelCase}} {{dataType}}, {{/required}}{{/vars}}) *{{classname}}`
New{{classname}} instantiates a new {{classname}} object
This constructor will assign default values to properties that have it defined,
and makes sure properties required by API are set, but the set of arguments
will change when the set of required properties is changed
### New{{classname}}WithDefaults
`func New{{classname}}WithDefaults() *{{classname}}`
New{{classname}}WithDefaults instantiates a new {{classname}} object
This constructor will only assign default values to properties that have it defined,
but it doesn't guarantee that properties required by API are set
{{#vars}}
### Get{{name}}
`func (o *{{classname}}) Get{{name}}() {{vendorExtensions.x-go-base-type}}`
Get{{name}} returns the {{name}} field if non-nil, zero value otherwise.
### Get{{name}}Ok
`func (o *{{classname}}) Get{{name}}Ok() (*{{vendorExtensions.x-go-base-type}}, bool)`
Get{{name}}Ok returns a tuple with the {{name}} field if it's non-nil, zero value otherwise
and a boolean to check if the value has been set.
### Set{{name}}
`func (o *{{classname}}) Set{{name}}(v {{vendorExtensions.x-go-base-type}})`
Set{{name}} sets {{name}} field to given value.
{{^required}}
### Has{{name}}
`func (o *{{classname}}) Has{{name}}() bool`
Has{{name}} returns a boolean if a field has been set.
{{/required}}
{{#isNullable}}
### Set{{name}}Nil
`func (o *{{classname}}) Set{{name}}Nil(b bool)`
Set{{name}}Nil sets the value for {{name}} to be an explicit nil
### Unset{{name}}
`func (o *{{classname}}) Unset{{name}}()`
Unset{{name}} ensures that no value is present for {{name}}, not even an explicit nil
{{/isNullable}}
{{/vars}}
{{#vendorExtensions.x-implements}}
### As{{{.}}}
`func (s *{{classname}}) As{{{.}}}() {{{.}}}`
Convenience method to wrap this instance of {{classname}} in {{{.}}}
{{/vendorExtensions.x-implements}}
{{/vendorExtensions.x-is-one-of-interface}}
{{/isEnum}}
{{#isEnum}}
## Enum
