多语言调用看典古籍OCR API示例

看典古籍OCR API接口地址：https://ocr.kandianguji.com/ocr_api

必传参数：token、email、image（图像base64编码），支持 Form Data 和 JSON 两种请求方式。

常见可选参数说明，完整参数请查看 API使用文档 ：

以下为各编程语言调用示例，请将 your_token 和 your_email 替换为您自己的API Token和账号。

Python

import base64
import requests

# 读取图像并转为base64
with open("test.jpg", "rb") as f:
    image_base64 = base64.b64encode(f.read()).decode("utf-8")

# Form Data 方式
response = requests.post(
    "https://ocr.kandianguji.com/ocr_api",
    data={
        "token": "your_token",
        "email": "your_email",
        "image": image_base64,
        "version": "v2",
        "det_mode": "auto",
        "image_size": 2000,
    }
)
result = response.json()
print(result)

JavaScript (Node.js)

const fs = require("fs");
const axios = require("axios");

const imageBase64 = fs.readFileSync("test.jpg", { encoding: "base64" });

// JSON 方式
axios.post("https://ocr.kandianguji.com/ocr_api", {
    token: "your_token",
    email: "your_email",
    image: imageBase64,
    version: "v2",
    det_mode: "auto",
})
.then(res => console.log(res.data))
.catch(err => console.error(err));

JavaScript (前端/Fetch)

const fileInput = document.getElementById("file");
const file = fileInput.files[0];
const reader = new FileReader();

reader.onload = async function() {
    const imageBase64 = reader.result.split(",")[1]; // 去掉 data:image/...;base64, 前缀

    const formData = new FormData();
    formData.append("token", "your_token");
    formData.append("email", "your_email");
    formData.append("image", imageBase64);
    formData.append("version", "v2");
    formData.append("det_mode", "auto");

    const response = await fetch("https://ocr.kandianguji.com/ocr_api", {
        method: "POST",
        body: formData,
    });
    const result = await response.json();
    console.log(result);
};
reader.readAsDataURL(file);

cURL (命令行)

# Form Data 方式
curl -X POST https://ocr.kandianguji.com/ocr_api \
  -F "token=your_token" \
  -F "email=your_email" \
  -F "image=$(base64 -w 0 test.jpg)" \
  -F "version=v2" \
  -F "det_mode=auto"
