passing # symbol to params hash in rails

Question

I am handling some hashtag processing in a rails application.

Say us that I have programmed an endpoint which receives through params hash a string containing some hashtags. Some like that

This string contains this #hashtag and this #one .

I am using postman for testing my endpoints.

Now, when in postman I perform some like this:

{{url}}/add?content=content=This string contains this #hashtag and this #one

I receive in the params the string "content"=>"This string contains this " . That is, from the first occurrence of symbol # the remaining string is cut.

Very aware that my question is some naive, I dare to ask why that? What have I done wrong? and how could I manage for passing strings containing the # symbol?

Answer 1

You need to make sure you encode whatever you are sending over in param.

URI.encode("This string contains this #hashtag and this #one")

#=> This%20string%20contains%20this%20%23hashtag%20and%20this%20%23one

Answer 2

Update your postman request to replace the # with %23

{{url}}/add?content=This string contains this %23hashtag and this %23one

In the future when doing something like this you can select a part of the params(or the whole thing) and right click and select EncodeURIComponent , as explained here
