[iOS] Url encoded parentheses in custom vars

[Антон Погонец]

We trying to pass user-agent as custom parameter to DFP on iOS and faced with two issues.
User agent contains parentheses ()

1. We urlencode custom parametrs and pass them to cust_params and then -[IMAAdsRequest initWithAdTagUrl:adDisplayContainer:contentPlayhead:userContext:]. But in http request from sdk parentheses not urlencoded.

2. Params with parentheses not forwarded to third party ad networks.

Can you help with this?

Hi Антон,

Can you send us -

• Charles logs.
• Code snippets
• And how you are encoding your parenthesis. It might be an issue here.

Also note that this is strictly an iOS issues and not something related to our SDK. 

Thanks,

Here is my tag with encoded params

Sample with hardcoded tag and produced charles log is provided. As you can see in tag () encoded to %28%29 but in charles log it is decoded back.

Second charles log illustrates that deviceUA with ) not forwarded from dfp to tremor media. When I remove ) it forwarded normally.

Thanks
Anton

Hi Антон,

Thank you for the tags and Charles logs. Charles would always decode it back when you look at the specific parameters. But when I use your ad tag, and look at the %28 and %29 encoding, they seem to be properly decoded but the following up responses are not encoding them. For now, I would suggest you not to use parentheses for your encoding and I will look into this and update you by tomorrow. Also, I'm not getting any ad responses back with your Ad Tag and for one that I did receive, there are no media files/creatives appended in the response.

Thanks,
