requests请求/sdapi/v1/img2img问题

[AIjie-sen]

请求img2img，文档中显示init_images参数是[str]，我按照此格式请求，提示{'error': 'HTTPException', 'detail': 'Invalid encoded image', 'body': '', 'errors': ''}。如何解决

[serendipity109]

from PIL import Image
from gradio.processing_utils import encode_pil_to_base64

def img2img_basic_image_base64(uri) -> str:
    return encode_pil_to_base64(Image.open(uri))

img = img2img_basic_image_base64("/home/adamwang/Desktop/img.jpg")

"init_images": [
    img
],

我在知乎上搜到了一个可以成功图生图的payload，经过对该payload的分析比较。发现参数中的"mask"变量必须要有，否则就会出现这个错误。对于"mask"参数应当同样是以base64编码的空白图像数据。这边可以先拿该payload中的试一下。

同样可以使用在线的base64转图片的工具站看一下，就是什么都没有的空白图片。
这个"mask"的作用类似ComfyUI中的“Latent——潜藏空间”
甚至，你可以用相同图片的base64编码来当作mask的参数，这也是可以执行的，只不过生成出来的图片会有点奇怪
