SSRS中生成二维码

1.二维码搭建, fastapi,qrcode,python-barcode

from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
import qrcode
from io import BytesIO
from fastapi.responses import StreamingResponse
import barcode
from barcode.writer import ImageWriter

app = FastAPI()

@app.get("/generate_qr")
async def generate_qr(data: str = ""):
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_L,
        box_size=10,
        border=4,
    )
    qr.add_data(data)
    qr.make(fit=True)
    img = qr.make_image(fill_color="black", back_color="white")

    img_io = BytesIO()
    img.save(img_io, 'PNG')
    img_io.seek(0)

    return StreamingResponse(img_io, media_type="image/png")

@app.get("/generate_barcode")
async def generate_barcode(data: str = "123456789012"):
    if not data:
        raise HTTPException(status_code=400, detail="Data parameter is required")

    # 选择条形码格式，例如EAN-13
    #ean = barcode.get_barcode_class('ean13')
    # 选择条形码格式（Code 39）
    code39 = barcode.get_barcode_class('code39')

    try:
        #ean_barcode = ean(data, writer=ImageWriter())
        code39_barcode = code39(data, writer=ImageWriter())
    except barcode.errors.BarcodeError:
        raise HTTPException(status_code=400, detail="Invalid data for EAN-13 barcode")

    img_io = BytesIO()
    #ean_barcode.write(img_io)
    code39_barcode.write(img_io)
    img_io.seek(0)

    return StreamingResponse(img_io, media_type="image/png")

if __name__ == '__main__':
    import uvicorn
    uvicorn.run(app, host='localhost', port=8000)

2.地址生成
