AI换装

描述

本接口用于在云端按照指定换装模板处理输入图像，生成 AI 换装图像。

版本

1.0

图片要求

图片格式：JPG、PNG。

调用 URL

    正式环境：https://openapi.meitu.com
    任务提交接口：https://openapi.meitu.com/api/v1/sdk/sync/push
    任务名称(task)：/v1/AI_Change_Clothes/change_clothes_default/477312
    任务类型(task_type)：formula

task 的最后一段是换装 ID。本文请求与 SDK 示例使用原文列出的“黄油月光”换装 ID 477312；使用其他换装模板时，应将最后一段替换为对应的换装 ID。
