A tour of grpc:03 - proto serialization / deserialization

In the last one , We installed and configured protoc, Write some simple message, And use protoc Automatically generated code . In this paper , We will try proto Serialization function of , And try to serialize and deserialize between different languages .

proto go  serialize

1.  newly build sample package , To facilitate testing , We write a that can generate random data random.go

​2.  stay sample  Write under the package  generator.go  It is convenient for us to generate subsequent test data

​3.  newly build  serializer , To write   Binary serialization  file.go

​4.  stay serializer Write under the package json.go Appoint json Serialization rules

​5.  stay serializer  Write a unit test under the package  file_test.go

​6.  modify Makefile  Add a command to run the test

​7. make test Run it , Can be observed  temp  Under the folder are generated  laptop.bin and  laptop.json

​ Can be observed ,JSON  Serialized result size   It's about   Binary serialization size  5 times .

proto Java  serialize

1.  To write sample.Generator  Class is used to generate   Test data 【 It's equivalent to integrating random.go  and  generator.go】

​2.  To write  serializer.Serializer  Class is used to implement serialization

​3.  Next, we write a unit test SerializerTest  Test class .

​

​ You can also see , here  JSON The size of serialization is about the size of binary serialization 5 Double span

Language serialization test

We might as well go further , Try to make golang The result of binary serialization , use Java Deserialize back

1.  We are going to Java The serialized result is deleted , then golang The binary serialization result of ⻉ To Java Project root

2.  Above SerializerTest Unit testing , Let's add another

​3.  Run unit tests , You can see golang The serialized result was successfully deserialized , contrast golang and Java Of JSON serialize   result , Proved proto Cross language serialization capability .
