我无法解析YouTube持续时间到日期或日期时间,我搜索并访问了许多网站,但是无法解析youtube字符串持续时间
Youtube持续时间示例为:PT15M33S
答案 0 :(得分:1)
它的ISO 8601 durations的格式为 P [n] Y [n] M [n] DT [n] H [n] M [n] S
示例:
20秒:
PT20.0S
一年,3个月,3天,4小时,5分钟,10秒:
P1Y3M3DT4H5M10S
很遗憾,dart没有提供解析器api Duration class 因此,您必须自己分析并输入Duration并转换为Datatime
您可以尝试Match-class
String durationString = "P2Y5M3W4DT5H4M2S";
String regxPattern= "^P(\\d+Y)?(\\d+M)?(\\d+W)?(\\d+D)?(T(\\d+H)?(\\d+M)?(\\d+S)?)?\$";
print(regxPattern);
RegExp re = new RegExp(regxPattern);
if (re.hasMatch(durationString)) {
for (var m in re.allMatches(durationString)) {
print("total:"+m.group(0));
print("Y:"+m.group(1));
print("M:"+m.group(2));
print("W:"+m.group(3));
print("D:"+m.group(4));
print("Time:"+m.group(5));
print("H:"+m.group(6));
print("M:"+m.group(7));
print("S:"+m.group(8));
Duration fastestMarathon = new Duration(hours:m.group(6),
minutes:m.group(7),
second,m.group(8));
}
}
