## OpenAI Dalle3 接口
先来看下官方接口的参数和响应值:
Body
```json
{
"model": "dall-e-3",
"prompt": "A cute baby sea otter",
"n": 1,
"size": "1024x1024"
}
```
Response
```json
{
"created": 1589478378,
"data": [
{
"url": "https://..."
},
{
"url": "https://..."
}
]
}
```
## 编排思路
1. 通过 AI 来优化图片绘制的提示词(这部省略了,自己找提示词即可)
2. 通过`HTTP 模块`调用 Dalle3 接口,获取图片的 URL。
3. 通过`文本加工`来构建`Markdown`的图片格式。
4. 通过`指定回复`来直接输出图片链接。
### 1. 构建 HTTP 模块
请求参数直接复制 Dalle3 接口的即可,并求改 prompt 为变量。需要增加一个`Headers.Authorization`
Body:
```json
{
"model": "dall-e-3",
"prompt": "{{prompt}}",
"n": 1,
"size": "1024x1024"
}
```
Headers:
`Authorization: Bearer sk-xxx`
Response:
响应值需要根据Dalle3接口的返回值进行获取我们只绘制了1张图片所以只需要取第一张图片的URL即可。给 HTTP 模块增加一个`key``data[0].url`的输出值。
### 2. 文本加工 - 构建图片链接
`Markdown`语法中`![图片描述](图片链接)`表示插入图片,图片链接由`HTTP模块`输出。
因此可以增加一个输入来接收`HTTP模块`的图片链接输出,并在`文本内容`中通过变量来引用图片链接,从而得到一个完整的`Markdown`图片格式。
### 3. 指定回复
指定回复可以直接输出传入的内容到客户端,因此可以直接输出加工好的`Markdown`图片格式即可。
