## 引擎1:豆包万相(Doubao Seedream)
|
||
|
||
使用火山引擎 Ark API 的 Doubao Seedream 模型,支持文生图、图生图、多图融合、图片编辑。
|
||
|
||
### 前提条件
|
||
|
||
- `curl.exe`(Windows内置)
|
||
- Ark API Key: `ark-119a37ed-f123-42fc-aea6-b38d47d47fc0-f7ddf`
|
||
- API端点: `https://ark.cn-beijing.volces.com/api/v3/images/generations`
|
||
|
||
### 模式一览
|
||
|
||
| 模式 | `image`参数 | 用途 |
|
||
|---|---|---|
|
||
| 文生图 | 省略或`[]` | 从文字描述生成图片 |
|
||
| 图生图 | `["url1"]` | 风格转换、精修、变换 |
|
||
| 多图融合 | `["url1","url2",...]` | 最多14张参考图融合 |
|
||
| 图片编辑 | `["url1"]` + 编辑提示词 | 移除/替换元素、换背景等 |
|
||
|
||
默认模型: `doubao-seedream-5-0-260128`
|
||
|
||
### 文生图(Windows PowerShell)
|
||
|
||
```powershell
|
||
$tmpFile = "$env:TEMP\request.json"
|
||
$prompt = "YOUR_PROMPT_HERE"
|
||
$json = @"
|
||
{"model":"doubao-seedream-5-0-260128","prompt":"$prompt","size":"2k","sequential_image_generation":"disabled","response_format":"url","stream":false,"watermark":false}
|
||
"@
|
||
$sw = [System.IO.StreamWriter]::new($tmpFile, $false, (New-Object System.Text.UTF8Encoding $false))
|
||
$sw.Write($json); $sw.Close()
|
||
|
||
$response = curl.exe -s -X POST https://ark.cn-beijing.volces.com/api/v3/images/generations `
|
||
-H "Content-Type: application/json" `
|
||
-H "Authorization: Bearer ark-119a37ed-f123-42fc-aea6-b38d47d47fc0-f7ddf" `
|
||
-d "@$tmpFile" | ConvertFrom-Json
|
||
|
||
$imageUrl = $response.data[0].url
|
||
$outputPath = Join-Path (Get-Location) "output-name.png"
|
||
curl.exe -s -o $outputPath $imageUrl
|
||
Write-Output $outputPath
|
||
```
|
||
|
||
### 图生图/图片编辑(本地文件输入,Windows PowerShell)
|
||
|
||
```powershell
|
||
$imgBytes = [System.IO.File]::ReadAllBytes((Resolve-Path "path\to\input.png"))
|
||
$imgBase64 = [System.Convert]::ToBase64String($imgBytes)
|
||
|
||
$tmpFile = "$env:TEMP\request.json"
|
||
$prompt = "YOUR_EDIT_INSTRUCTIONS_HERE"
|
||
$json = @"
|
||
{"model":"doubao-seedream-5-0-260128","prompt":"$prompt","image":["data:image/png;base64,$imgBase64"],"size":"2k","sequential_image_generation":"disabled","response_format":"url","stream":false,"watermark":false}
|
||
"@
|
||
$sw = [System.IO.StreamWriter]::new($tmpFile, $false, (New-Object System.Text.UTF8Encoding $false))
|
||
$sw.Write($json); $sw.Close()
|
||
|
||
$response = curl.exe -s -X POST https://ark.cn-beijing.volces.com/api/v3/images/generations `
|
||
-H "Content-Type: application/json" `
|
||
-H "Authorization: Bearer ark-119a37ed-f123-42fc-aea6-b38d47d47fc0-f7ddf" `
|
||
-d "@$tmpFile" | ConvertFrom-Json
|
||
|
||
$imageUrl = $response.data[0].url
|
||
$outputPath = Join-Path (Get-Location) "output-name.png"
|
||
curl.exe -s -o $outputPath $imageUrl
|
||
Write-Output $outputPath
|
||
```
|
||
|
||
### 多图融合
|
||
|
||
```json
|
||
{
|
||
"model": "doubao-seedream-5-0-260128",
|
||
"prompt": "把图1的人物穿上图2的衣服,站在图3的场景中",
|
||
"image": ["url1", "url2", "url3"],
|
||
"size": "2k",
|
||
"sequential_image_generation": "disabled",
|
||
"response_format": "url",
|
||
"stream": false,
|
||
"watermark": false
|
||
}
|
||
```
|
||
|
||
### 批量生成(最多15张)
|
||
|
||
```json
|
||
{
|
||
"model": "doubao-seedream-5-0-260128",
|
||
"prompt": "一个女孩和她的布偶牛在过山车上,分别呈现早晨、中午、傍晚的场景",
|
||
"sequential_image_generation": "auto",
|
||
"sequential_image_generation_options": { "max_images": 3 },
|
||
"size": "2k",
|
||
"response_format": "url",
|
||
"stream": false,
|
||
"watermark": false
|
||
}
|
||
```
|
||
|
||
### 豆包参数参考
|
||
|
||
| 参数 | 类型 | 必填 | 说明 |
|
||
|---|---|---|---|
|
||
| `model` | string | 是 | `doubao-seedream-5-0-260128`(默认)或 `doubao-seededit-3-0-i2i`(精确编辑) |
|
||
| `prompt` | string | 是 | 文本提示词,最多~300中文字或~600英文词 |
|
||
| `image` | string[] | 否 | 参考图片URL或Base64(`data:image/png;base64,...`),最多14张 |
|
||
| `size` | string | 否 | `2k`(默认)、`3k`、`4k` 或 `WIDTHxHEIGHT`(如`2048x1024`),必须小写 |
|
||
| `response_format` | string | 否 | `url`(下载链接,24h有效)或 `b64_json` |
|
||
| `sequential_image_generation` | string | 否 | `disabled`(默认,单图)或 `auto`(模型决定批量数) |
|
||
| `sequential_image_generation_options` | object | 否 | `{ "max_images": N }` N为1-15,仅auto模式 |
|
||
| `stream` | boolean | 否 | `false`(等待全部)或 `true`(逐张返回) |
|
||
| `watermark` | boolean | 否 | 添加"AI Generated"水印,默认`false` |
|
||
| `guidance_scale` | float | 否 | 文本遵循度(CFG),范围[1,10],仅seededit-3-0-i2i |
|
||
| `seed` | int32 | 否 | 可复现种子,仅seededit-3-0-i2i |
|
||
|
||
### 豆包尺寸指南
|
||
|
||
| 别名 | 近似分辨率 | 适用场景 |
|
||
|---|---|---|
|
||
| `2k` | ~2048px | **默认** — 质量与速度平衡 |
|
||
| `3k` | ~3072px | 高质量,产品图 |
|
||
| `4k` | ~4096px | 最终生产质量 |
|
||
| `WIDTHxHEIGHT` | 自定义 | 如`2048x1024`宽幅横幅 |
|
||
|
||
像素约束:两个维度必须在[1280, 4096],最大3:1宽高比。
|
||
|
||
### 豆包提示词技巧
|
||
|
||
- **描述场景**: 主体、动作、环境、氛围
|
||
- **指定风格**: "电影大片感"、"水彩画风"、"赛博朋克"、"oc渲染"、"超现实主义"
|
||
- **质量关键词**: "光线追踪"、"景深"、"极致的光影"、"动态模糊"
|
||
- **编辑指令**: "把背景换成海滩"、"移除画面中的人物"、"将风格改为水彩画"
|
||
- **中文提示词原生支持** — 无需翻译为英文
|
||
|
||
### Windows注意事项
|
||
|
||
| 问题 | 解决方案 |
|
||
|---|---|
|
||
| PowerShell 5.1给JSON加UTF-8 BOM | **不要**用`Set-Content`或`[System.Text.Encoding]::UTF8`,用`[System.IO.StreamWriter]::new($path, $false, (New-Object System.Text.UTF8Encoding $false))` |
|
||
| PowerShell破坏curl中的`"` | **始终**写JSON到临时文件,用`-d "@$tmpFile"` |
|
||
| curl别名冲突 | 用`curl.exe`而非`curl` |
|
||
| 续行符 | 用反引号`` ` `` |
|
||
|
||
### 豆包错误处理
|
||
|
||
- **401**: API Key无效 — 检查Authorization头
|
||
- **400**: 请求错误 — 检查提示词长度、图片格式、尺寸值
|
||
- **429**: 限流 — 等待后重试
|
||
- **500**: 服务器错误 — 稍后重试
|
||
|
||
### 精确编辑模型
|
||
|
||
需要精细编辑时,`doubao-seededit-3-0-i2i`提供额外控制:
|
||
|
||
```json
|
||
{
|
||
"model": "doubao-seededit-3-0-i2i",
|
||
"prompt": "Change the dress color to red",
|
||
"image": ["data:image/png;base64,..."],
|
||
"guidance_scale": 5.5,
|
||
"seed": 42,
|
||
"size": "adaptive",
|
||
"response_format": "url",
|
||
"watermark": false
|
||
}
|
||
```
|
