首先感謝laf提供免費使用Midjourney API接口和云函數(shù)，需要詳細(xì)了解的可以訪問他們的官網(wǎng)論壇。
感謝論壇前面幾位的分享，我做了參考。都有參考就不列啦哈?。?！

直接開始：

第一步

復(fù)制MJ-SEND云函數(shù)到laf云平臺，并發(fā)布獲得云函數(shù)訪問地址“https://xxx.laf.dev/mj-sent”

import cloud from '@lafjs/cloud'
import { Midjourney, MidjourneyMessage } from 'midjourney'
const SERVER_ID = '' // Midjourney 服務(wù) ID
const CHANNEL_ID = '' // Midjourney 頻道 ID
const SALAI_TOKEN = '' // Midjourney 服務(wù) Token

const Limit = 100
const MaxWait = 3

const client = new Midjourney({
  ServerId: SERVER_ID,
  ChannelId: CHANNEL_ID,
  SalaiToken: SALAI_TOKEN,
  Debug: true,
  SessionId: SALAI_TOKEN,
  Limit: Limit,
  MaxWait: MaxWait
});

export default async function (ctx: FunctionContext) {
  const { type, param } = ctx.body
  switch (type) {
    case 'RetrieveMessages':
      return await RetrieveMessages(param)
    case 'imagine':
      return await imagine(param)
    case 'upscale':
      return await upscale(param)
    case 'variation':
      return await variation(param)
  }

}

// 查詢最近消息
async function RetrieveMessages(param) {
  console.log("RetrieveMessages")
  const client = new MidjourneyMessage({
    ChannelId: CHANNEL_ID,
    SalaiToken: SALAI_TOKEN,
  });
  const msg = await client.RetrieveMessages();
  console.log("RetrieveMessages success ", msg)
  return msg
}

// 創(chuàng)建生圖任務(wù)
async function imagine(param) {
  console.log("imagine", param)
  const { question, msg_Id } = param
  const msg = await client.Imagine(
    `[${msg_Id}] ${question}`,
    (uri: string, progress: string) => {
      console.log("loading", uri, "progress", progress);
    }
  );
  console.log("imagine success ", msg)
  return true
}

// upscale 放大圖片
async function upscale(param) {
  console.log("upscale", param)
  const { question, index, id, url } = param
  const hash = url.split("_").pop()?.split(".")[0] ?? ""
  console.log(hash)
  const msg = await client.Upscale(
    question,
    index,
    id,
    hash,
    (uri: string, progress: string) => {
      console.log("loading", uri, "progress", progress);
    }
  );
  console.log("upscale success ", msg)
  return msg
}

// variation 變換圖片
async function variation(param) {
  console.log("variation", param)
  const client = new Midjourney({
    ServerId: SERVER_ID,
    ChannelId: CHANNEL_ID,
    SalaiToken: SALAI_TOKEN,
    Debug: true,
    SessionId: SALAI_TOKEN,
    Limit: Limit,
    MaxWait: 100
  });
  const { question, index, id, url } = param
  const hash = url.split("_").pop()?.split(".")[0] ?? ""
  const msg = await client.Variation(
    question,
    index,
    id,
    hash,
    (uri: string, progress: string) => {
      console.log("loading", uri, "progress", progress);
    }
  );
  console.log("variation success ", msg)
  return msg
}

第二步

?到我的huggingface空間復(fù)制到自己的服務(wù)器，查找“https://xxx.laf.dev/mj-sent”替換成你自己的云函數(shù)地址“

3、五分鐘不到就可以免費擁有CHATGPT+Midjourney啦，加油?。∪ペA得AI第一桶金?。。?span toymoban-style="hidden">文章來源地址http://www.zghlxwxcb.cn/news/detail-606008.html

到了這里，關(guān)于五分鐘零基礎(chǔ)開發(fā)chatgpt+Midjourney工具贏得被動收入的文章就介紹完了。如果您還想了解更多內(nèi)容，請在右上角搜索TOY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
