openai中的DALL-E2生成图像

使用步骤

使用 OpenAI 的 DALL-E 2 生成图像需要以下步骤：

1. 准备文本描述：需要一个文本描述来描述所需生成的图像。

2. 发送 API 请求：使用对应语言的 API 库向 OpenAI API 发送请求，并将文本描述作为请求参数。

3. 解析 API 返回：从 API 返回中解析生成的图像并保存到本地。

代码举例

Java

import java.io.IOException;
import java.io.InputStreamReader;
import java.io.Reader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;

import com.google.gson.Gson;

public class OpenAIDalle2 {
    public static void main(String[] args) throws IOException {
        // 发送 API 请求
        URL url = new URL("https://api.openai.com/v1/images/generations");
        HttpURLConnection con = (HttpURLConnection) url.openConnection();
        con.setRequestMethod("POST");
        con.setRequestProperty("Content-Type", "application/json");
        con.setRequestProperty("Authorization", "Bearer ");
        con.setDoOutput(true);

        // 请求参数
        Map requestJson = new HashMap<>();
        requestJson.put("model", "image-alpha-001");
        requestJson.put("prompt", "A four-legged animal that barks");
        requestJson.put("num_images", 1);
        requestJson.put("size", "1024x1024");

        // 发送请求
        con.getOutputStream().write(new Gson().toJson(requestJson).getBytes());

        // 解析 API 返回
        Reader reader = new InputStreamReader(con.getInputStream());
        OpenAIDalle2Response response = new Gson().fromJson(reader, OpenAIDalle2Response.class);

        // 保存图像到本地
        // ...
    }

    private static class OpenAIDalle2Response {
        String data;
        // ...
    }
}

nodejs

安装客户端

使用Node.js生成图像，需要先安装OpenAI API客户端

npm install openai

导入OpenAI API客户端

const openai = require("openai");

配置您的API密钥

openai.promise.setApiKey("");

生成图像

openai.ImageCompletion.create({
    prompt: "A 3-story red brick building with a white door and windows. In front of the building, there is a green tree with a swing hanging from it.",
    n: 1,
    size: "1024x1024",
    response_format: "url"
}).then((image) => {
    console.log(image.data[0].url);
}).catch((error) => {
    console.error(error);
});

python

安装OpenAI API客户端

pip install openai

导入OpenAI API客户端

import openai

配置您的API密钥

openai.api_key = ""

生成图像

prompt = "A 3-story red brick building with a white door and windows. In front of the building, there is a green tree with a swing hanging from it."

completion = openai.Completion.create(
    engine="image-alpha-001",
    prompt=prompt,
    max_tokens=1024,
    n=1,
    stop=None,
    temperature=0.5,
)

print(completion.choices[0].text)
