活字格图片上传功能（批量）

这个报错真的恶心，又看不了他服务器源码，接口文档又是错的

活字格V9获取图片失败bug，报错404-CSDN博客

代码BUG记录：

问题：上传多个文件的base64编码被最后一个文件给覆盖导致循环多张图片的base64编码都一样

在代码中，使用了一个循环来加载图片并获取其base64编码。然而，在image.onload回调函数中，使用了i变量，而这个变量在循环结束后可能已经发生了变化。这可能导致所有的回调函数都在循环结束后执行，因此它们都使用了相同的i值。

为了解决这个问题，可以使用一个闭包来保存每次循环的i值。可以通过将i传递给一个立即执行的函数，并在该函数内部返回一个新的函数，该新函数就是image.onload的回调函数。

}

活字格发票识别功能（批量）*待完善

这个改了一下数据库，打算把刚刚上传的图片标记一个false，识别后标为true，之前的图片再加一个past_标记一下，批量识别就只用识别FALSE的文件了

因为要循环的缘故，把后续操作都改成js的形式

代码：

// 获取当前页面上名称为account的单元格
// 获取当前页面
var page = Forguncy.Page;
var access_token = page.getCell("access_token").getValue();var invoiceTypeChooseCell = page.getCell("invoice_type_choose");var invoiceCodeCell = page.getCell("invoice_code");

这个代码暂时只能识别一张图片
