问题描述
我有一条服务总线,并且转换数据的唯一方法是通过JavaScript.我需要将Guid转换为字节数组,以便随后将其转换为Ascii85并将其缩小为20个字符串以用于接收客户端点.
I have a service bus, and the only way to transform data is via JavaScript. I need to convert a Guid to a byte array so I can then convert it to Ascii85 and shrink it into a 20 character string for the receiving customer endpoint.
任何想法都会受到赞赏.
Any thoughts would be appreciated.
推荐答案
尝试一下(需要大量测试):
Try this (needs LOTS of tests):
var guid = "{12345678-90ab-cdef-fedc-ba0987654321}";
window.alert(guid + " = " + toAscii85(guid))
function toAscii85(guid)
{
var ascii85 = ""
var chars = guid.replace(/\{?(?:(\w+)-?)\}?/g, "$1");
var patterns = ["$4$3$2$1", "$2$1$4$3", "$1$2$3$4", "$1$2$3$4"];
for(var i=0; i < 32; i+=8)
{
var block = chars.substr(i, 8)
.replace(/(..)(..)(..)(..)/, patterns[i / 8]) //poorman shift
var decValue = parseInt(block, 16);
var segment = ""
if(decValue == 0)
{
segment = "z"
}
else
{
for(var n = 4; n >= 0; n--)
{
segment = String.fromCharCode((decValue % 85) + 33) + segment;
decValue /= 85;
}
}
ascii85 += segment
}
return "<~" + ascii85 + "~>";
}
