Finagle HTTP and Thrift Clients \ Servers Example

This is example of how you can write Finagle HTTP / Thrift Servers / Clients.

git remote rm origin

已存在的文件夹或 Git 仓库 cd existing_folder git init git remote add origin git@gitee.com:walter80/finagle_scala_examples.git git add . git commit git push -u origin master

Try It!

To try it, you should run HTTP by following command:

$ sbt "run-main com.acme.Example.HttpServer"

Then you should run Thrift Server:

$ sbt "run-main com.acme.Example.ThriftServer"

And now we ready to do some test calls using HTTP Client:

$ sbt "run-main com.acme.Example.HttpClient"

At HTTP Client you should get following output:

))) Issuing two requests in parallel:
))) Received result for authorized request: hello world
))) Unauthorized request errored (as desired): com.acme.Example.HttpClient$InvalidRequest

Since HTTP Service also sending async request to Thrift Server using Thrift Client, in out put of HTTP Server you should see following output:

>> Received response: hi through Thrift
