**FastAPI** prendra le modèle Pydantic à partir de là, générera le `JSON Schema` et le placera au bon endroit.

Le bon endroit est :

* Dans la clé `content`, qui a pour valeur un autre objet JSON (`dict`) qui contient :
    * Une clé avec le type de support, par ex. `application/json`, qui contient comme valeur un autre objet JSON, qui contient :
        * Une clé `schema`, qui a pour valeur le schéma JSON du modèle, voici le bon endroit.

		Enable        bool               `json:"enable"`
		RootCAs       *x509.CertPool     `json:"-"`
		SkipVerify    bool               `json:"skipVerify"`
		ClientAuth    tls.ClientAuthType `json:"clientAuth"`
		ClientTLSCert string             `json:"clientTLSCert"`
		ClientTLSKey  string             `json:"clientTLSKey"`
	} `json:"tls"`
	SASL struct {
		Enable    bool   `json:"enable"`
		User      string `json:"username"`

        - 媒体类型的密钥，例如 `application/json` ，它包含另一个`JSON`对象作为值，该对象包含：
            - 一个键` schema` ，它的值是来自模型的`JSON Schema`，正确的位置在这里。
                - **FastAPI**在这里添加了对OpenAPI中另一个地方的全局JSON模式的引用，而不是直接包含它。这样，其他应用程序和客户端可以直接使用这些JSON模式，提供更好的代码生成工具等。

///

**在OpenAPI中为该路径操作生成的响应将是：**

```json hl_lines="3-12"
{
    "responses": {
        "404": {
            "description": "Additional Response",
            "content": {

		},
	}
)

// Args opa general purpose policy engine configuration.
type Args struct {
	URL         *xnet.URL             `json:"url"`
	AuthToken   string                `json:"authToken"`
	Transport   http.RoundTripper     `json:"-"`
	CloseRespFn func(r io.ReadCloser) `json:"-"`
}

// Validate - validate opa configuration params.
func (a *Args) Validate() error {

// XferStats has transfer stats for replication
type XferStats struct {
	Curr    float64          `json:"currRate" msg:"cr"`
	Avg     float64          `json:"avgRate" msg:"av"`
	Peak    float64          `json:"peakRate" msg:"p"`
	N       int64            `json:"n" msg:"n"`
	measure *rateMeasurement `json:"-"`
	sma     *SMA             `json:"-"`
}

// Clone returns a copy of XferStats
func (rx *XferStats) Clone() *XferStats {

O **FastAPI** pegará o modelo do Pydantic, gerará o `JSON Schema`, e adicionará no local correto.

O local correto é:

* Na chave `content`, que tem como valor um outro objeto JSON (`dict`) que contém:
    * Uma chave com o media type, como por exemplo `application/json`, que contém como valor um outro objeto JSON, contendo::
        * Uma chave `schema`, que contém como valor o JSON Schema do modelo, sendo este o local correto.
