main.py

from fastapi import FastAPI, File, UploadFile

app = FastAPI()
from rapidocr_onnxruntime import RapidOCR

# det_model_path同理
model = RapidOCR()


# 1、导入对应的包
from fastapi.middleware.cors import CORSMiddleware

app = FastAPI()

# 2、声明一个 源 列表；重点：要包含跨域的客户端 源
origins = [
    "https://hycjack-fastapi-rapidocr.hf.space/",
    "http://localhost",
    "http://localhost:7860",
    # 客户端的源
    "http://127.0.0.1:7860"
]

# 3、配置 CORSMiddleware
app.add_middleware(
    CORSMiddleware,
    allow_origins=origins,  # 允许访问的源
    allow_credentials=True,  # 支持 cookie
    allow_methods=["*"],  # 允许使用的请求方法
    allow_headers=["*"]  # 允许携带的 Headers
)
