Question

我最近将我的项目的ServiceStack.Text从3.9.23升级到最新的稳定版。

我有一些单元测试，确保我们输出的日期格式不会改变。它们现在在升级后失败了。测试看起来像这样：

[Test]
[TestCase(2012, 06, 22, 03, 26, 23, 837, "\"\\/Date(1340328383837+0200)\\/\"")] // Daylight savings time test in DK (+0200)
[TestCase(1997, 10, 30, 11, 23, 49, 060, "\"\\/Date(878207029060+0100)\\/\"")]
[TestCase(2050, 01, 14, 00, 00, 00, 000, "\"\\/Date(2525727600000+0100)\\/\"")] 
public void SerializeDate_ReturnsExpectedOutput(int year, int month, int day, int hour, int minute, int second, int ms, string expected)
{
    var dt = new DateTime(year, month, day, hour, minute, second, ms).ToUniversalTime();
    dt = TimeZoneInfo.ConvertTimeFromUtc(dt, TimeZoneInfo.FindSystemTimeZoneById("W. Europe Standard Time"));

    string serialized = ServiceStack.Text.JsonSerializer.SerializeToString(dt);

    Assert.AreEqual(expected, serialized, "DateTime Serialization failure, got {0} but expected {1} for DateTime = {2}",
        serialized, expected, dt);
}

测试失败，因为ServiceStack.Text现在将UTC偏移输出为零，这不是我想要的，所以我得到：

  String lengths are both 30. Strings differ at index 21.
  Expected: ""\\/Date(1340328383837+0200)\\/""
  But was:  ""\\/Date(1340328383837-0000)\\/""
  ---------------------------------^

如何配置ServiceStack.Text以使用旧行为？

Answer 1

环境：

ServiceStack.Text.JsConfig.DateHandler = ServiceStack.Text.JsonDateHandler.DCJSCompatible;

为我解决问题，基本上我需要将DateTimeKind.Unspecified的DateTimes视为当地时间。我查看了ServiceStack.Text源代码，这个处理程序就是这样做的。请注意，处理程序会抛弃UTC偏移量，并将字符串解析为DateTime输入时将时间视为本地时间。（幸运的是，这也适用于我的应用程序）。

ServiceStack.Text输出UTC偏移量
