Fluid -46- 基于 Simpletex API 构建公式识别页面

本文最后更新于：2025年4月28日下午

公式识别越来越贵了，本文基于 Simpletex API 构建了自己的公式识别前端应用，记录过程。

实现思路

核心为基于 Simpletex API 的公式识别，将其封装在后端
用python 的flask 构建后端
html 前端
开机自启动
hexo 支持

核心实现

直接上代码

Simpeltex_ocr 实现

        random = Random()
        for i in range(randomlength):
            str += chars[random.randint(0, length)]

        sorted_keys.sort()
        for key in sorted_keys:
            if pre_sign_string:

        pre_sign_string += "&secret=" + secret
        header["sign"] = hashlib.md5(pre_sign_string.encode()).hexdigest()
        return header, req_data

    def query(self, img_path):
        img_file = {"file": open(img_path, 'rb')}
        data = {}
        # 请求参数数据（非文件型参数），视情况填入，可以参考各个接口的参数说明
        header, data = self.get_req_data(data, self.SIMPLETEX_APP_ID, self.SIMPLETEX_APP_SECRET)
        res = requests.post("https://server.simpletex.cn/api/latex_ocr", files=img_file, data=data, headers=header)
        return json.loads(res.text)

需要填入你的 Simpletex API 的 SIMPLETEX_APP_ID 和 SIMPLETEX_APP_SECRET

BASE_URL = 'https://your_link'; 需要替换为你自己的链接
使用示例：

示例链接：https://www.zywvvd.com/navigates/formular_reco/

暂时免费开放出来供大家使用，调用多了我再藏起来 …

加入 hexo

需要开机自启动，Nginx 映射（略），加入 fluid 主题

开机自启动

创建 /lib/systemd/system/formular-reco.service 文件，写入：

[Unit]
Description = Service to support formular reco for www.zywvvd.com
After = network.target

[Service]
ExecStart = /home/vvd/anaconda3/bin/python app.py
WorkingDirectory = /home/vvd/programs/formular_reco
StandardOutput = inherit
StandardError = inherit
Restart = always
User = vvd

[Install]
WantedBy=multi-user.target

开机自启：

1	`sudo systemctl enable formular-reco.service`

加入 fluid

创建 Hexo/source/navigates/formular_reco/index.md 文件

const BASE_URL = 'https://your-link'; 需要换为你自己的地址

在 _config.fluid.yml 文件中加入到 menu:

1	`{ key: "formular_reco", link: "/navigates/formular_reco", icon: "iconfont icon-a-checkformula" , event_key : "Navigation-Formular-Reco" },`

在 Hexo/source/_data/languages/zh-CN.yml 中添加

formular_reco:
  menu: '公式识别'
  title: '公式识别'
  subtitle: '公式识别'
