python - 从 python 字符串中切片消息

Question

我正在检索字符串格式的错误消息。我必须从中切出消息。我试过将它转换成一个列表，但那是将整个消息放入单独的列表中。尝试了 python 子字符串/切片但无法检索消息。

错误信息是这样的

    (vmodl.fault.InvalidArgument) {
   dynamicType = <unset>,
   dynamicProperty = (vmodl.DynamicProperty) [],
   msg = 'A specified parameter was not correct. \nspec.name',
   faultCause = <unset>,
   faultMessage = (vmodl.LocalizableMessage) [
      (vmodl.LocalizableMessage) {
         dynamicType = <unset>,
         dynamicProperty = (vmodl.DynamicProperty) [],
         key = 'com.vmware.vim.vpxd.dvs.uniqueField1.label',
         arg = (vmodl.KeyAnyValue) [
            (vmodl.KeyAnyValue) {
               dynamicType = <unset>,
               dynamicProperty = (vmodl.DynamicProperty) [],
               key = 'dvs1',
               value = 'ExampleDVS1'
            },
            (vmodl.KeyAnyValue) {
               dynamicType = <unset>,
               dynamicProperty = (vmodl.DynamicProperty) [],
               key = 'prop',
               value = 'spec.name'
            },
            (vmodl.KeyAnyValue) {
               dynamicType = <unset>,
               dynamicProperty = (vmodl.DynamicProperty) [],
               key = 'value',
               value = 'ExampleDVS1'
            },
            (vmodl.KeyAnyValue) {
               dynamicType = <unset>,
               dynamicProperty = (vmodl.DynamicProperty) [],
               key = 'op',
               value = 'create'
            },
            (vmodl.KeyAnyValue) {
               dynamicType = <unset>,
               dynamicProperty = (vmodl.DynamicProperty) [],
               key = 'dvs2',
               value = 'ExampleDVS1'
            }
         ],
         message = 'A VDS ExampleDVS1 with spec.name as ExampleDVS1 already exists, cannot create VDS ExampleDVS1'
      }
   ],
   invalidProperty = u'spec.name'
}

如您所见，有一个消息字段，我想将其检索为 'A VDS ExampleDVS1 with spec.name as ExampleDVS1 already exists, cannot create VDS ExampleDVS1'

试试这个:

re.search(r"message\s+=\s+'([^']*)'",text_string,re.M).group(1)
