python post protobuf

This paper describes how to send data protobuf use Python.

Installation protobuf

tar zxvf protobuf 2.6 . 1 . tar gz
cd protobuf-2.6.1
./configure
make
make install

Successful installation.

// Check protoc version 
protoc --version

python installation protobuf

cd protobuf- 2.6 . 1 / python
python setup.py build
python setup.py install

Environment set up is completed, the following give a demo.

Creating my_bidding.proto

package tutorial;

message Person {
    required string name = 1;
    optional int32 age = 2;
    repeated BankCard bankcard = 3;
    message BankCard {
        required string id = 1;
    }
    optional RealEstate estate = 4;
    message RealEstate {
        required string address = 1;
        optional int32 value = 2;
    }
    optional bool isSingle = 5;
    optional SexualOrientation orientation = 6;
    enum SexualOrientation {
        ManOnly = 1 ;
        WomanOnly = 2;
        BiSexual = 3;
    }
}

Compile proto file

protoc -I=. --python_out=. ./my_bidding.proto

Compile successful, will produce my_bidding_pb2.py.

Python scripting

# python2
# coding = utf-8

import my_bidding_pb2
import httplib

person = my_bidding_pb2.Person()
person.name = 'logan'
person.age = 25
person.isSingle = False
person.orientation = 3

bankcard1 = person.bankcard.add()
bankcard1.id = '100'

bankcard2 = person.bankcard.add()
bankcard2.id = '101'

real_estate = person.estate
real_estate.address = 'beijing'
real_estate.value = 1000

print person

data = person.SerializeToString()

CONTENT_TYPE = "application/octet-stream"
CONTENT_TYPE_HEADER = "Content-type"

conn = httplib.HTTPConnection('sever_host', 'server_port')
conn.request('POST', 'server_path', data,
             {CONTENT_TYPE_HEADER: CONTENT_TYPE})
response = conn.getresponse()

print response
print response.status
print response.read()
