Wdraw 2.3 | 二次元API，由WZH团队-Wdraw开发小组开发，目前已开放免费测试
W系列项目交流群：957780885
WTO 即 Wdraw to OpenAI ，本帖教程将介绍如何将 wdraw 转为OpenAI格式后直接通过oneapi调用
感谢wbot团队为论坛佬友提供免费API（赞助 wbot），感谢 edwa 佬对代码进行了完善，感谢他们！

生成图例
简单上手
第一步，绑定域名
注册cf账号并绑定域名，并提前分配一个二级域名给worker
第二步，配置worker
新建一个worker，覆盖粘贴下面的代码，然后在路由中将二级域名和worker绑定。
woker.js
默认使用Telegraph官方图床，你也可以自建，详参： 【Cloudflare系列教程】利用Pages部署免费Telegraph图床
addEventListener("fetch", event => {
event.respondWith(handleRequest(event.request));
});
async function handleRequest(request) {
if (request.method === "OPTIONS") {
return new Response("", {

const search = url.searchParams

const uniqueId = `imggen-${currentTimestamp}`;

const responsePayload = {

};
const dataString = JSON.stringify(responsePayload);
return new Response(`data: ${dataString}\n\n`, {
status: 200,
headers: {
"Content-Type": "text/event-stream",
'Access-Control-Allow-Origin': '*',
"Access-Control-Allow-Headers": '*'
}
});
} catch (error) {
return new Response("Internal Server Error: " + error.message, {
status: 500,
headers: {
"Content-Type": "application/json",
'Access-Control-Allow-Origin': '*',
"Access-Control-Allow-Headers": '*'
}
});
}
}
第三步 配置oneapi
在oneapi新建一个自定义渠道，base_url 填 worker 绑定的二级域名，密钥 test，模型 wdraw-2.3
快来试试吧
