1、开启api调用模式
开启api模式，关闭可视化窗口，并且建议关闭登录权限（详细查看文章最后Stable Diffusion之Ubuntu下部署-CSDN博客）
./webui.sh --disable-safe-unpickle --api --nowebui
2、查看接口列表
访问对应的网页地址 http://192.168.xx.xx:7860/docs#
3、text2img接口调用
#接口地址
http://192.168.xx.xx:9876/sdapi/v1/txt2img
参数内容
application/json
batch_size 生成批次个数

}返回结果
其中 images[] 数据就是我们需要的图片base64字符串，补充前缀用于保存、浏览器查看
