Hello, I installed protobuf(3,1,0) on my mac, and I use open and read to
read a .proto file, but I always get the error:
# f =
open('/Users/junhao.wen/Hao/tutorial/Protocol_buffers_tutorial/tutorial/Protocol_buffers_basic_python/address_book/addressbook.proto',
'rb')
Here is my code:
! /usr/bin/python
import addressbook_pb2
import sys
# This function fills in a Person message based on user input.
def PromptForAddress(person):
person.id = int(raw_input("Enter person ID number: "))
person.name = raw_input("Enter name: ")
email = raw_input("Enter email address (blank for none): ")
if email != "":
person.email = email
while True:
number = raw_input("Enter a phone number (or leave blank to finish): ")
if number == "":
break
phone_number = person.phone.add()
phone_number.number = number
type = raw_input("Is this a mobile, home, or work phone? ")
if type == "mobile":
phone_number.type = addressbook_pb2.Person.MOBILE
elif type == "home":
phone_number.type = addressbook_pb2.Person.HOME
elif type == "work":
phone_number.type = addressbook_pb2.Person.WORK
else:
print "Unknown phone type; leaving as default value."
# Main procedure: Reads the entire address book from a file,
# adds one person based on user input, then writes it back out to the same
# file.
# if len(sys.argv) != 2:
# print "Usage:", sys.argv[0], "ADDRESS_BOOK_FILE"
# sys.exit(-1)
address_book = addressbook_pb2.AddressBook()
# Read the existing address book.
try:
# f = open(sys.argv[1], "rb")
# f =
open('/Users/junhao.wen/Hao/tutorial/Protocol_buffers_tutorial/tutorial/Protocol_buffers_basic_python/address_book/addressbook.proto',
'rb')
f =
open('/Users/junhao.wen/Hao/tutorial/Protocol_buffers_tutorial/tutorial/Protocol_buffers_basic_python/address_book/test.proto',
'rb')
address_book.ParseFromString(f.read())
f.close()
except IOError:
print sys.argv[1] + ": Could not open file. Creating a new one."
# Add an address.
PromptForAddress(address_book.person.add())
# Write the new address book back to disk.
f = open(sys.argv[1], "wb")
f.write(address_book.SerializeToString())
f.close()
Can someone give me a hint??? I really dont know where is the problem, and
in the github, always nobody respond question...
Thanks
