Dify version

0.15.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

The reproduction steps are as follows:

1. Add an HTTP request node in workflow;
2. Configure the post request, where the Headers add the key Host and the value is customized;
3. Execute the http request node;
4. When grabbing the headers from the interface server, it was found that the Host in the original request headers had been replaced; As shown in the following figure

Due to the replacement of the Headers content, some interfaces may require specifying the Host when making requests, which can lead to exceptions

✔️ Expected Behavior

The Headers of the HTTP request node in workflow retains the original information and sends it to the server

❌ Actual Behavior

Now, in the dify version of workflow, the HTTP request node will replace the Headers content when sending requests

The issue you're experiencing with the HTTP request node in Dify replacing the 'Host' header is likely due to how headers are managed in the code. The 'Host' header is set in the to_log method for logging purposes, but this does not affect the actual request sent ^[1]. However, there might be other parts of the system or network configuration that could be altering the 'Host' header during request execution.

To address this, you might want to check if there are any middleware or network configurations in your environment that could be modifying the 'Host' header. Additionally, reviewing the _assembling_headers method in the Executor class could provide insights into how headers are being set or modified before the request is sent ^[1]. If the issue persists, consider looking into any custom configurations or proxies that might be affecting the request headers.
