【Godot4.4】写入和读取ZIP文件

概述

Godot提供了ZIPPacker类型来读写ZIP压缩包文件。本文是简单的写入和读取文件操作测试笔记。

写入纯文本文件

extends Button



func _ready():
	write_zip_file("1.zip",func(zip_packer):
		write_txt_file_to_zippack(zip_packer,"1.txt","hhhhh")
		write_txt_file_to_zippack(zip_packer,"2.md","hhhhh")
		write_txt_file_to_zippack(zip_packer,"3.html","hhhhh")
	)

func write_zip_file(zip_path:String,call_back:Callable):
	var zip_packer := ZIPPacker.new()
	var err := zip_packer.open(zip_path,ZIPPacker.APPEND_CREATE)
	if err != OK:
		return err
	call_back.call(zip_packer)
	zip_packer.close_file()
	zip_packer.close()
	return OK

# 在zip中写入纯文本文件
func write_txt_file_to_zippack(zip_packer:ZIPPacker,file_neme:String,file_content:String):
	zip_packer.start_file(file_neme)
	zip_packer.write_file(file_content.to_utf8_buffer())

写入任意二进制文件

extends Button



func _ready():
	write_zip_file("1.zip",func(zip_packer):
		write_txt_file(zip_packer,"1.txt","hhhhh")
		write_txt_file(zip_packer,"2.md","hhhhh")
		write_txt_file(zip_packer,"3.html","hhhhh")
		write_binary_file(zip_packer,"1.jpg",get_binary_file_bytes("res://1.jpg"))
	)

# 返回文件的二进制字节数组形式
func get_binary_file_bytes(file_path:String):
	return 	FileAccess.get_file_as_bytes(file_path)

func write_zip_file(zip_path:String,call_back:Callable):
	var zip_packer := ZIPPacker.new()
	var err := zip_packer.open(zip_path,ZIPPacker.APPEND_CREATE)
	if err != OK:
		return err
	call_back.call(zip_packer)
	zip_packer.close_file()
	zip_packer.close()
	return OK

# 在zip中写入纯文本文件
func write_txt_file(zip_packer:ZIPPacker,file_neme:String,file_content:String):
	zip_packer.start_file(file_neme)
	zip_packer.write_file(file_content.to_utf8_buffer())

# 在zip中写入二进制文件
func write_binary_file(zip_packer:ZIPPacker,file_neme:String,file_content:PackedByteArray):
	zip_packer.start_file(file_neme)
	zip_packer.write_file(file_content)

读取ZIP

获取文件列表

extends Button


func _ready():
	read_zip_file("1.zip",func(zip_reader:ZIPReader):
		var files = zip_reader.get_files()
		print(files) # ["1.txt", "2.md", "3.html", "1.jpg"]
	)

# 返回文件的二进制字节数组形式
func get_binary_file_bytes(file_path:String):
	return 	FileAccess.get_file_as_bytes(file_path)

func write_zip_file(zip_path:String,call_back:Callable):
	var zip_packer := ZIPPacker.new()
	var err := zip_packer.open(zip_path,ZIPPacker.APPEND_CREATE)
	if err != OK:
		return err
	call_back.call(zip_packer)
	zip_packer.close_file()
	zip_packer.close()
	return OK

# 读取ZIP
func read_zip_file(zip_path:String,call_back:Callable):
	var zip_readder := ZIPReader.new()
	var err := zip_readder.open(zip_path)
	if err!= OK:
		return err
	call_back.call(zip_readder)
	zip_readder.close()

# 在zip中写入纯文本文件
func write_txt_file(zip_packer:ZIPPacker,file_neme:String,file_content:String):
	zip_packer.start_file(file_neme)
	zip_packer.write_file(file_content.to_utf8_buffer())

# 在zip中写入二进制文件
func write_binary_file(zip_packer:ZIPPacker,file_neme:String,file_content:PackedByteArray):
	zip_packer.start_file(file_neme)
	zip_packer.write_file(file_content)

读取纯文本文件内容

extends Button



func _ready():
	read_zip_file("1.zip",func(zip_reader:ZIPReader):
		var txt = get_zip_txt(zip_reader,"1.txt")
		print(txt)
	)

# 返回ZIP压缩包中指定名称的纯文本文件的文本内容
func get_zip_txt(zip_reader:ZIPReader,file_neme:String):
	var txt_bytes = zip_reader.read_file(file_neme)
	return txt_bytes.get_string_from_utf8()


# 返回文件的二进制字节数组形式
func get_binary_file_bytes(file_path:String):
	return 	FileAccess.get_file_as_bytes(file_path)

func write_zip_file(zip_path:String,call_back:Callable):
	var zip_packer := ZIPPacker.new()
	var err := zip_packer.open(zip_path,ZIPPacker.APPEND_CREATE)
	if err != OK:
		return err
	call_back.call(zip_packer)
	zip_packer.close_file()
	zip_packer.close()
	return OK

# 读取ZIP
func read_zip_file(zip_path:String,call_back:Callable):
	var zip_readder := ZIPReader.new()
	var err := zip_readder.open(zip_path)
	if err!= OK:
		return err
	call_back.call(zip_readder)
	zip_readder.close()

# 在zip中写入纯文本文件
func write_txt_file(zip_packer:ZIPPacker,file_neme:String,file_content:String):
	zip_packer.start_file(file_neme)
	zip_packer.write_file(file_content.to_utf8_buffer())

# 在zip中写入二进制文件
func write_binary_file(zip_packer:ZIPPacker,file_neme:String,file_content:PackedByteArray):
	zip_packer.start_file(file_neme)
	zip_packer.write_file(file_content)
