我想要做的是输入像
["01001000 01100101 01111001"]
这样的字符串并将其转换为["Hey"]
或相反,输入["Hey"]
并将其转换为["01001000 01100101 01111001"]
String encode(String value) {
// Map each code unit from the given value to a base-2 representation of this
// code unit, adding zeroes to the left until the string has length 8, and join
// each code unit representation to a single string using spaces
return value.codeUnits.map((v) => v.toRadixString(2).padLeft(8, '0')).join(" ");
}
String decode(String value) {
// Split the given value on spaces, parse each base-2 representation string to
// an integer and return a new string from the corresponding code units
return String.fromCharCodes(value.split(" ").map((v) => int.parse(v, radix: 2)));
}
void main() {
print(encode("Hey")); // Output: 01001000 01100101 01111001
print(decode("01001000 01100101 01111001")); // Output: Hey
}
有没有二进制转文本或二进制转pdf的方法?我已经搜索了一段时间但找不到如何做到这一点。
