我正在尝试将这样的字符串解析为"devDependencies": {
"bower": "~1.3.1",
"grunt": "~0.4.4",
"grunt-autoprefixer": "~2.0.0",
"grunt-cli": "~0.1.13",
"grunt-contrib-jasmine": "~0.6.1",
"grunt-karma": "~0.8.0",
"grunt-karma-sonar": "~0.1.3",

"karma-junit-sonarqube-reporter": "0.0.1",
"load-grunt-tasks": "^3.4.0",

如何从字符串表示中实例化一个字节？
答案 0 :(得分：3)
这是一个使用正则表达式和parseInt的解决方案。
def parseBytes(s: String): List[Byte] =
(raw"\b0x([0-9a-f]{2})\b".r
.findAllMatchIn(s)
.map(g => Integer.parseInt(g.group(1), 16).toByte)
.toList)
测试：
scala> parseBytes("0x4e 0x01 0x09 0xff")
0: List[Byte] = List(78, 1, 9, -1)
