将Base64字符串解码为字节数组 将字节数组写入PDF文件 示例代码 下面是一个简单的示例代码,演示了如何将Base64字符串转换为PDF文件: importjava.io.FileOutputStream;importjava.util.Base64;publicclassBase64ToPDF{publicstaticvoidmain(String[]args){Stringbase64String="JVBERi0xLjMKJcTl8uXrp/Og0MTGCjIuMjAxMi...
importjava.io.FileOutputStream;importjava.io.OutputStream;publicclassBase64ToPDF{publicstaticvoidmain(String[]args){Stringbase64String="Your Base64 string here";// 解码Base64字符串byte[]bytes=Base64.getDecoder().decode(base64String);// 写入PDF文件try(OutputStreamstream=newFileOutputStream("output...

base64生成PDF文件 我的想法是首先把base64存入MemoryStream中然后用 FileStream保存,但是当代码写好运行到byte[] b = stream.GetBuffer();这句的时候报错:无法访问 MemoryStream 的内部缓冲区。然后我就给改成了 byte[] b = stream.ToArray();程序就正常了 贴出我的全部demo,共同交流 publicvoidBase64StringTo...
public static File base64ToFile(String base64) { if(base64==null||"".equals(base64)) { return null;} byte[] buff=Base64.decode(base64);File file=null;FileOutputStream fout=null;try { file = File.createTempFile("tmp", null);fout=new FileOutputStream(file);fout.write(buff);} ...

是指将以base64编码的字节数组转换为PDF文件格式并进行输出。下面是完善且全面的答案: Base64编码是一种将二进制数据转换为可打印字符的编码方式,常用于在网络传输中传递二进制数据。将base64编码的字节数组输出为PDF文件,需要进行解码和转换操作。 以下是实现从base64字节数组输出PDF的步骤: 解码base64字节数组:使用...
