Stable Diffusion之API接口调用

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

{ "batch_size": 1, "cfg_scale": 7, "negative_prompt": "NSFW", "override_settings": { "sd_model_checkpoint": "anythingv5nijimix_25BEST.safetensors [8bc735ed57]" }, "clip_skip": 1, "prompt": "full body, a girl, blue hand, Long yellow hair, blue shoes, write background, <lora:20240320-1710939437372:1>", "restore_faces": false, "sampler_index": "DPM++ SDE Karras", "sampler_name": "", "script_args": [], "seed": -1, "steps": 20, "tiling": false, "width": 512, "height": 512 }

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

data:image/png;base64,
