js string to BytEs

1、string 转 byte[] String str = "Hello";byte[] srtbyte = str.getBytes();2、byte[] 转 string byte[] srtbyte;String res = new String(srtbyte);System.out.println(res);3、设定编码方式相互转换 String str = "hello";byte[] srtbyte = ...

string 转 byte[]的方法: byte[] midbytes=isoString.getBytes("UTF8"); //为UTF8编码 byte[] isoret = srt2.getBytes("ISO-8859-1"); //为ISO-8859-1编码 其中ISO-8859-1为单字节的编码 byte[]转string的方法: String isoString = new String...

// js代码function string2ByteArray(str) { let bytes = [] for (let i = 0; i < str.length; i++) { const code = str.charCodeAt(i) bytes = bytes.concat([code]) } return bytes}// as代码public static function convertStringToByteArray...

没有这个方法…js转bytes可以自己写一个: function stringToBytes ( str ) { var ch, st, re = []; for (var i = 0; i < str.length; i++ ) { ch = str.charCodeAt(i); // get char st = []; // set up "stack" do { st.push( ch & 0xFF ); // pu...

string base64Str = "图片的BASE64字符串";byte[] bytes = System.Convert.FromBase64String(base64Str);using (System.IO.MemoryStream ms = new System.IO.MemoryStream(bytes)){ return System.Drawing.Image.FromStream(ms);}
