employees.proto file, compiles with protoc easily. and I import the resulting code into my own python code file as below.
syntax = "proto3";
package empList;
message Employee {
int32 id = 1;
string name = 2;
float salary = 3;
}
message Employees {
repeated Employee employees = 1;
}
Python file to add data and convert binary file to json.
import employees_pb2 as Test
from google.protobuf.json_format import MessageToDict
def main():
emps = Test.Employees()
obj1 = emps.employees.add()
obj1.id = 10
obj1.name = "Suresh"
obj1.salary = 1000
print(emps)
with open("./serializedFile", "wb") as fd:
t = emps.SerializeToString()
fd.write(t)
json_msg_string = MessageToDict(t, preserving_proto_field_name = True)
print("jsonSting : ", json_msg_string)
empsRead = Test.Employees()
with open("./serializedFile", "rb") as rfd:
bstr = rfd.read()
print(bstr)
empsRead.ParseFromString(bstr)
print(empsRead)
if __name__ == "__main__":
main()
```
On running, I get the following traceback and I have been unable to understand the why I get the error of "AttributeError: 'bytes' object has no attribute 'DESCRIPTOR". Error is in the comment.
