我们首先导入Java的Base64类,然后定义一个Base64编码的字符串base64EncodedString。接下来,我们使用Base64.getDecoder().decode()方法将Base64编码的字符串解码成字节数组decodedBytes。 步骤2:使用字节数组创建一个PDF文件 // 引入java.io.FileOutputStream类importjava.io.FileOutputStream;// 创建PDF文件StringpdfFil...
是一种将base64编码的字符串转换为可视化的PDF文件的过程。Base64是一种用于将二进制数据编码为ASCII字符的编码方式,它常用于在网络传输中传递二进制数据。 要实现从base64字符串渲染pdf文件,可以按照以下步骤进行: 解码base64字符串:使用编程语言中的Base64解码函数,将base64字符串解码为二进制数据。 创建PDF文件:使...
如何使用对虾创业板将Base64字符串转换为pdf文件 、、、 我想从DB记录中生成pdf文件。将其编码为Base64字符串并将其存储到DB。效果很好。现在我想要反向操作,如何解码Base64字符串并再次生成pdf文件? encoded_string = Base64.encode64(File.open("#{Rails.root}/tmp/pdf/("#{R 浏览1提问于2017-09-13得...

在尝试使用 TypeScript(在 VSCode 扩展中)解码相同的 base64 编码字符串时Buffer,即使用以下函数:function decodeBase64(base64String: string): string { const buf: Buffer = Buffer.from(base64String, "base64"); return buf.toString();}// the base64 encoded string is usually extracted from an XML...
The base64 string was encoded from a .docs file. When I decoded the base64 string to .pdf, I got this error: "Adobe Acrobat Reader could not open '' because it is either not a supported file type of because the file has been damaged (for example, it was sent as email attachm...
