[GitHub] [pulsar] grantwwu opened a new issue #3769: Websocket interface
does not decode URLencoding
grantwwu opened a new issue #3769: Websocket interface does not decode URLencoding
URL: https://github.com/apache/pulsar/issues/3769
**Describe the bug**
The Pulsar websocket server does not appear to decode URL encoded URLs properly. This leads to consuming from (and presuming producing to, but I didn't test this) the wrong topic.
**To Reproduce**
Steps to reproduce the behavior:
1. Attempt to consume from a *new* topic whose name includes an RFC 3986 reserved character. For this bug report, I am using the topic name `public/default/pusheennstormy[]`. To encode this into a valid URL, note that you will need to URL encode the square brackets. The resulting URL ought to look something like this: `pulsar-broker.petuum-system:8080/ws/v2/consumer/persistent/public/default/pusheennstormy%5B%5D/3ab32f35-6c3f-4e8a-a120-409091bb3cea`
2. Note that the the new topic created is not `public/default/pusheennstormy[]` as expected, but actually is the URL encoded form.
**Expected behavior**
The `public/default/pusheennstormy[]` topic should be created.
