This will expect (convert, validate, document, etc.) a JSON body like:

```JSON hl_lines="11"
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": [
        "rock",
        "metal",
        "bar"
    ],

    ), "not used parameters should not be included"
    assert (
        '"syntaxHighlight.theme": "obsidian"' in response.text
    ), "parameters with middle dots should be included in a JSON compatible way"
    assert (
        '"dom_id": "#swagger-ui"' in response.text
    ), "default configs should be preserved"
    assert "presets: [" in response.text, "default configs should be preserved"
    assert (

    response = client.get("/docs")
    assert response.status_code == 200, response.text
    assert (
        '"syntaxHighlight": false' in response.text
    ), "syntaxHighlight should be included and converted to JSON"
    assert (
        '"dom_id": "#swagger-ui"' in response.text
    ), "default configs should be preserved"
    assert "presets: [" in response.text, "default configs should be preserved"
    assert (

	}

	var inputs []string

	// Parse parameters
	switch {
	case *stdin:
		// Parse 'mc support inspect --json' output
		input := struct {
			File string `json:"file"`
			Key  string `json:"key"`
		}{}
		got, err := io.ReadAll(os.Stdin)
		if err != nil {
			fatalErr(err)
		}
		fatalErr(json.Unmarshal(got, &input))
		inputs = []string{input.File}
		*keyHex = input.Key
	case len(flag.Args()) == 1:
		var err error

	CreatedBefore *time.Time          `yaml:"createdBefore,omitempty" json:"createdBefore"`

## 返回 Token

`token` 端点的响应必须是 JSON 对象。

响应返回的内容应该包含 `token_type`。本例中用的是**Bearer**Token，因此， Token 类型应为**`bearer`**。

返回内容还应包含 `access_token` 字段，它是包含权限 Token 的字符串。

本例只是简单的演示，返回的 Token 就是 `username`，但这种方式极不安全。

/// tip | "提示"

下一章介绍使用哈希密码和 <abbr title="JSON Web Tokens">JWT</abbr> Token 的真正安全机制。

但现在，仅关注所需的特定细节。

///

package config

import (
	"encoding/json"
	"fmt"
	"strconv"
	"strings"
)

// BoolFlag - wrapper bool type.
type BoolFlag bool

// String - returns string of BoolFlag.
func (bf BoolFlag) String() string {
	if bf {
		return "on"
	}

	return "off"
}

// MarshalJSON - converts BoolFlag into JSON data.
func (bf BoolFlag) MarshalJSON() ([]byte, error) {

///

## What is "Form Data"

The way HTML forms (`<form></form>`) sends the data to the server normally uses a "special" encoding for that data, it's different from JSON.

**FastAPI** will make sure to read that data from the right place instead of JSON.

/// note | "Technical Details"

Data from forms is normally encoded using the "media type" `application/x-www-form-urlencoded` when it doesn't include files.

Da das Endergebnis nun in einer Datei `openapi.json` vorliegt, würden Sie die `package.json` ändern, um diese lokale Datei zu verwenden, zum Beispiel:

```JSON  hl_lines="7"

  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "generate-client": "openapi-ts --input ./openapi.json --output ./src/client --client axios"
  },
  "author": "",

type PoolDecommissionInfo struct {
	StartTime   time.Time `json:"startTime" msg:"st"`
	StartSize   int64     `json:"startSize" msg:"ss"`
	TotalSize   int64     `json:"totalSize" msg:"ts"`
	CurrentSize int64     `json:"currentSize" msg:"cs"`

	Complete bool `json:"complete" msg:"cmp"`
	Failed   bool `json:"failed" msg:"fl"`
	Canceled bool `json:"canceled" msg:"cnl"`
