thriftrw is a Python library to serialize and deserialize Thrift types.
Documentation is available on Read The Docs.
- No code generation. The
.thriftfiles are parsed and compiled in-memory at runtime. - No assumptions about how bytes are sent or received. The library concerns itself with serialization and deserialization only.
- Supports Python 2 and 3.
- Forward and cyclic references in types.
Given the .thrift file,:
// blog.thrift
typedef string PostUUID
typedef binary RichText
union Body {
1: string plainText
2: RichText richText
}
struct PostDetails {
1: required string author
2: required string subject
3: required Body body
}
exception UnauthorizedRequestError {
}
service BlogService {
PostUUID newPost(1: PostDetails post)
throws (1: UnauthorizedRequestError unauthorized);
}You can use the library to send and receive requests and responses like so,
# client.py
import thriftrw
blog = thriftrw.load('blog.thrift')
BlogService = blog.BlogService
def new_post():
post = blog.PostDetails(
author='...',
subject='...',
body=blog.Body(plainText='Hello, world!')
)
request = BlogService.newPost.request(post)
payload = blog.dumps(request)
# send_to_server is implemented by the user.
response_payload = send_to_server(payload)
response = blog.loads(BlogService.newPost.response, response_payload)
if response.unauthorized is not None:
raise response.unauthorized
else:
return response.success# server.py
import thriftrw
blog = thriftrw.load('blog.thrift')
BlogService = blog.BlogService
# The user's server handler calls handle_new_post with the payload.
def handle_new_post(request_payload):
request = blog.loads(BlogService.newPost.request, request_payload)
if request.post.author != 'admin':
response = BlogService.newPost.response(
unauthorized=blog.UnauthorizedRequestError()
)
else:
# create_post is implemented by the user.
post_uuid = create_post(request.post)
response = BlogService.newPost.response(success=post_uuid)
return blog.dumps(response)- Only the Thrift Binary protocol is supported at this time.
- Message wrappers for Thrift calls and responses are not supported at this time.
thriftrw provides the same functionality for Node.js.
