lua服务器读写文件,Lua读写文件代码示例

读写文件的模式：

r - 读取模式w - 写入模式(覆盖现有内容)

a - 附加模式(附加在现有内容之后)

b - 二进制模式

r+ - 读取更新模式(现有数据保留)

w+ - 写入更新模式(现有数据擦除)

a+ - 附加更新模式(现有数据保留，只在文件末尾附加)

do

--read data from file

function readFile()

local fileHandle = assert(io.open("test.txt", "r"), "not the file");

if fileHandle then

local outData = fileHandle:read("*all");

print(outData);

else

print("false");

end

fileHandle:close(errorInfo);

end

--write data to the file

function writeFile(dataBuffer)

local writeHandle = assert(io.open("write.txt", "a+"), "not the file");

if writeHandle then

writeHandle:write(dataBuffer);

print("true");

else

print("false");

end

writeHandle:close();

end

local inputData = 0;

repeat

inputData = io.read(); --write the data from io

writeFile(inputData);

until inputData == '#'
