@zxbyoyoyo Hello! I'm here to help you with any bugs, questions, or contributions while you wait for a human maintainer. Let's tackle this together!

I found a similar unsolved discussion titled "Why this not work" which might be related to the issue you're experiencing ^[1].

Regarding your issue with the HTTP node not supporting variable substitution in URLs, the Dify codebase does have functionality for handling variable substitution. The HTTP node is implemented in api/core/workflow/nodes/http_request/executor.py, where the _init_url method uses the VariablePool to substitute variables in the URL ^[2]. Additionally, there are test cases that verify this functionality, such as the test_template function, which demonstrates variable substitution in URLs, headers, and parameters ^[3].

If the substitution is not working as expected, it might be worth checking if the variables are correctly defined and accessible in the VariablePool. If the issue persists, reviewing the test cases might provide insights into how the substitution is intended to work.
