O que é a Validador de GUID?

A Validador de GUID checks whether a GUID ou UUID is correctly formed e identifies important informatoion such as its versão, variante e formato. This is useful quando working com APIs, bancos de dados, Microsoft .NET aplicações, distributed systems e aplicação identifiers.

What Does This Validador de GUID Verificar?

  • GUID structure e hexadecimal characters
  • Padrão 8-4-4-4-12 formato
  • GUID versão
  • GUID variante
  • Chaves e parentheses formatoos
  • URN formato
  • 32-character hexadecimal formato
  • Nil GUID
  • Maximum GUID value
  • Expected versão quando selected

GUID Formato

A standard GUID is normally represented as 36 characters including four hyphens in an 8-4-4-4-12 pattern.

550e8400-e29b-41d4-a716-446655440000

GUID Versions

GUIDs e UUIDs use a versão field to identify how the identifier was gerado. Este validador detects supported UUID versãos including v1, v3, v4, v5, v6, v7 e v8.

GUID Variant

The variante identifies the UUID layout used by the identifier. For the standard RFC UUID variante, the variante field normally begins com 8, 9, A ou B.

Nil GUID

The Nil GUID contém all zeros:

00000000-0000-0000-0000-000000000000

A Nil GUID é um valid special value e is not automatically treatedas an invalid GUID.

GUID Validation para Developers

GUID validation is useful before storing identifiers in bancos de dados, processing API requests ou passing identifiers between services. A formato-valid GUID does not necessarily mean that the identifier exists in your banco de dados ou belongs to a particular user ou resource.

Validador de GUID vs GUID Verificarer

A GUID validator focuses on whether the value follows GUID e UUID formatoting rules. A GUID checker can be usado para additional checks depending on the aplicação, such as checking a value against another identifier ou data source.

Frequently Asked Questions

A Validador de GUID checks whether a GUID ou UUID follows the expected formato e analyzes details such as its versão, variante, formato e normalized value.

Enter one ou more GUIDs em the validator e click Validar GUIDs. A ferramenta checks each value e displays whether it is valid ou invalid along com detailed informatoion.

Sim. Você pode enter multiple GUIDs, com one GUID per line, e validate them together.

O validador suporta standard 8-4-4-4-12 GUIDs, uppercase e lowercase values, braces, parentheses, URN formato e 32-character hexadecimal GUIDs sem hyphens.

Sim. O validador can identify UUID versãos including versão 1, 3, 4, 5, 6, 7 e 8 quando the versão informatoion is present in the identifier.

GUID e UUID generally refer to the same type of 128-bit identifier. GUID is commonly used in Microsoft e .NET environments, while UUID is the broader standards-based term.

The Nil UUID é um defined special UUID value consisting entirely of zeros. It should be treated as a special value rather than an ordinary gerado UUID.

O validador is designed to perform validation in your browser. Your GUID values do not need to be uploaded to a server para the validation process.
