concat节点设计用于连接字符串，可能包括一个可选的额外字符串，遵循特定的指导原则。它抽象了字符串连接的过程，确保操作遵守预定义的格式规则，例如在连接的字符串之间添加空格以提高可读性和连贯性。

|
|
# Input types
|
|
## Required
|
|
- string_a
|
|
- 要连接的主要字符串。它作为基础字符串，其他字符串将附加到它上面。
|
|
- Comfy dtype: STRING
|
|
- Python dtype: str
|
|
- string_b
|
|
- 要连接到主要字符串的第二个字符串，用于增强基本内容。
|
|
- Comfy dtype: STRING
|
|
- Python dtype: str
|
|
- string_c
|
|
- 一个可选的第三个字符串，可以连接到主要和第二个字符串上，为连接过程提供额外的灵活性。
|
|
- Comfy dtype: STRING
|
|
- Python dtype: str
|
|
|
|
# Output types
|
|
- string
|
|
- 连接最多三个字符串的结果，非空字符串之间可能添加可选的空格以确保适当的格式。
