禅心 发布于 2026/4/6 更新于 2026/4/18 Midjourney Imagine API 申请与使用
Midjourney 是一款强大的 AI 绘图工具，支持通过文本生成精美图像。本文档介绍 Midjourney Imagine API 的申请流程及核心功能的使用。
申请流程
访问 Midjourney Imagine API 文档页面点击「Acquire」按钮获取请求凭证。首次申请通常赠送免费额度。
基本使用
在界面填写 authorization 和 prompt（建议英文描述）。右侧提供调用代码生成及测试按钮。
主要请求参数：
prompt：图片描述词（支持自动翻译）。mode：生成模式，可选 fast/relax/turbo，默认 fast。timeout：超时时间（秒）。translation：是否自动翻译非英文 prompt。split_images：是否将 2x2 结果拆分返回单张。action/image_id：对历史图片继续操作时需指定。callback_url：异步回调地址。
返回结果示例：

task_id：任务 ID。image_id：图片唯一标识，用于后续变换操作。image_url：缩略图 URL。raw_image_url：原图 URL（更高清）。actions：可执行的操作列表（如放大、变换）。
图像放大与变换 针对生成的图片进行进一步操作。例如将 action 设为 variation2 并传入 image_id 可生成变体；设为 upscale4 可放大第四张图片。
upscale_2x / upscale_4x：放大 2 倍或 4 倍。zoom_out_2x / zoom_out_1_5x：缩小画面。pan_left / pan_right / pan_up / pan_down：画面偏移。
图像改写（垫图） 支持输入图片 URL 及描述文字进行改写。Prompt 开头添加 HTTPS 图片链接，后跟空格及文字描述。可使用 --iw 调整图片权重。
图像融合 支持传入多张图片 URL 实现融合效果。最多支持 5 张图片。格式为多个 URL 空格分隔后接文字 Prompt。

局部变换 支持局部重绘（Inpainting）。需传入生成图片的 image_id、掩码 mask（Base64 编码）及 action（variation_region）。

异步回调 API 支持 Webhook 回调。设置 callback_url 为接收 HTTP 请求的服务地址。生成成功或失败时，结果将通过 HTTP 请求发送。
{ "success" : true , "task_id" : "f6e39eaf-652a-4bf5-a15c-79d8b143b80a" , "image_url" : "..." , "image_id" : "..." , "task_id" : "..." }
{ "success" : false , "task_id" : "7ba0feaf-d20b-4c22-a35a-31ec30fc7715" , "error" : { "code" : "bad_request" , "message" : "Unrecognized argument(s): `-c`, `x`" } }
流式输出 支持流式输出以改善用户体验。修改请求头 accept 为 application/x-ndjson。
import requests
url = 'https://api.acedata.cloud/midjourney/imagine'
headers = {'content-type' :'application/json' ,'accept' :'application/x-ndjson' ,'authorization' :'Bearer {token}' }
body = {"prompt" :"a beautiful cat --v 6" }
r = requests.post(url, headers=headers, json=body, stream=True )
for line in r.iter_lines():
print (line.decode())
const axios = require ("axios" );
const url = "https://api.acedata.cloud/midjourney/imagine" ;
const headers = {
"content-type" : "application/json" ,
accept : "application/x-ndjson" ,
authorization : "Bearer {token}" ,
};
const body = {
prompt : "a beautiful cat --v 6" ,
action : "generate" ,
};
axios.post (url, body, { headers : headers, responseType : "stream" })
.then ((response ) => {
console .log (response.status );
response.data .on ("data" , (chunk ) => {
console .log (chunk.toString ());
});
})
.catch ((error ) => {
console .error (error);
});
注意：流式输出中 progress 字段表示生成进度（0-100）。未完全完成时 actions 为空。生成完成后中间图像 URL 将被销毁。可通过指定 accept=application/x-ndjson 和 callback_url 结合流式结果与异步回调。
