我正在为二进制文件进行基本的Ruby读/写操作。
这是我的代码
UAirship.push().pushNotificationDelegate = customPushDelegate
到目前为止一切看起来都不错。然后我尝试从文件中读取并将其转回ASCII格式。
afile = File.new("test.bin",'wb')
test = "abc"
a = test.unpack("B*")
File.open("test.bin", 'wb' ) do |output|
output.write a
end
print ("write #{a}\n") #Output "write ["011000010110001001100011"]
b = a.pack("B*")
print ("b is #{b}\n") #Output "b is abc"
然后出现错误。
" extract.ruby:23:s = File.binread("test.bin")
bits = s.pack("B*")
print ("s is #{s}\n") #Output is "s is ["011000010110001001100011"]"
print ("bits is #{bits}\n")
包' for" [\" 011000010110001001100011 \"]":String(NoMethodError)"
有人能帮我解释一下吗?非常感谢!
