generate - 生成示例参考

GenerateModel 是非常自由的一个接口，本质是组装一个 http post 请求，并尝试解析响应内容。但仍然有大量的 ai 模型无法覆盖（花样太多了），可使用 HttpUtils 直接请求。

一般涉及图片、声音、视频的生成，都会比较慢。所以大多平台都是异步的，生成结果是个 taskUrl 拼装的地址。

1、示例：输入文本，生成图片

import org.junit.jupiter.api.Test;
import org.noear.solon.ai.generate.GenerateModel;
import org.noear.solon.ai.generate.GenerateResponse;

@Test
public void case1_text2image() throws IOException {
    //生成图片
    String apiUrl = "https://dashscope.aliyuncs.com/api/v1/services/aigc/text2image/image-synthesis";
    String taskUrl = "https://dashscope.aliyuncs.com/api/v1/tasks/";
    
    GenerateModel generateModel = GenerateModel.of(apiUrl)
            .apiKey(apiKey)
            .taskUrl(taskUrl)
            .model("wanx2.1-t2i-turbo")
            .headerSet("X-DashScope-Async", "enable")
            .build();

    //一次性返回
    GenerateResponse resp = generateModel.prompt("a white siamese cat")
            .options(o -> o.size("1024x1024"))
            .call();

    //打印消息
    log.info("{}", resp.getContent());
    assert resp.getContent().getUrl() != null;
    assert resp.getContent().getUrl().startsWith("https://");
}

2、示例：输入图片，生成新图片（调整图片）

import org.junit.jupiter.api.Test;
import org.noear.solon.ai.generate.GenerateModel;
import org.noear.solon.ai.generate.GenerateResponse;

@Test
public void case2_image2image() throws IOException {
    //编辑图片
    String apiUrl = "https://dashscope.aliyuncs.com/api/v1/services/aigc/image2image/image-synthesis";
    String taskUrl = "https://dashscope.aliyuncs.com/api/v1/tasks/";
    
    GenerateModel generateModel = GenerateModel.of(apiUrl)
            .apiKey(apiKey)
            .taskUrl(taskUrl)
            .model("wanx2.1-imageedit")
            .headerSet("X-DashScope-Async", "enable")
            .build();

    GenerateResponse resp = generateModel.prompt(GeneratePrompt.ofKeyValues(
                    "function", "stylization_all",
                    "prompt", "转换成法国绘本风格",
                    "base_image_url", "http://wanx.alicdn.com/material/20250318/stylization_all_1.jpeg")
            )
            .options(o -> o.optionAdd("n", 1))
            .call();

    log.warn("{}", resp.getData());
    assert resp.getContent().getUrl() != null;
    assert resp.getContent().getUrl().startsWith("https://");
}

3、示例：输入文本，输出声音（音乐）

import org.junit.jupiter.api.Test;
import org.noear.solon.ai.generate.GenerateModel;
import org.noear.solon.ai.generate.GenerateResponse;

@Test
public void case3_music() throws IOException {
    String apiUrl = "https://ai.gitee.com/v1/async/music/generations";
    String taskUrl = "https://ai.gitee.com/v1/task/";
   
    GenerateModel generateModel = GenerateModel.of(apiUrl)
            .apiKey(apiKey)
            .taskUrl(taskUrl)
            .model("ACE-Step-v1-3.5B")
            .build();

    //一次性返回
   GenerateResponse resp = generateModel.prompt(GeneratePrompt.ofKeyValues(
                        "prompt", "大海的哥",
                        "task", "text2music"
                ))
                .call();

    log.warn("{}", resp.getData());
    assert resp.getContent().getUrl() != null;
    assert resp.getContent().getUrl().startsWith("https://");
}

4、示例：输入文本，生成视频

import org.junit.jupiter.api.Test;
import org.noear.solon.ai.generate.GenerateModel;
import org.noear.solon.ai.generate.GenerateResponse;

@Test
public void case4_video() throws IOException {
    //生成动画
    String apiUrl = "https://dashscope.aliyuncs.com/api/v1/services/aigc/video-generation/video-synthesis";
    String taskUrl = "https://dashscope.aliyuncs.com/api/v1/tasks/";
    
    GenerateModel generateModel = GenerateModel.of(apiUrl)
            .apiKey(apiKey)
            .taskUrl(taskUrl)
            .model("wan2.2-i2v-plus")
            .headerSet("X-DashScope-Async", "enable")
            .build();

    GenerateResponse resp = generateModel.prompt(GeneratePrompt.ofKeyValues(
                    "prompt", "一只猫在草地上奔跑",
                    "img_url", "https://cdn.translate.alibaba.com/r/wanx-demo-1.png")
            )
            .options(o -> o.optionAdd("resolution", "480P")
                    .optionAdd("prompt_extend", true))
            .call();

    log.warn("{}", resp.getData());
    assert resp.getContent().getUrl() != null;
    assert resp.getContent().getUrl().startsWith("https://");
}
