Walkthrough

The function handle_x_migration in twikit/x_client_transaction/utils.py was updated to explicitly set the "User-Agent" header at the start of the function before the initial GET request to "https://x.com". No other changes to the function’s logic, control flow, or error handling were made.

Changes

File(s) Change Summary
twikit/x_client_transaction/utils.py Explicitly set "User-Agent" header before initial GET request in handle_x_migration.

Poem

A rabbit hops through headers anew,
With "User-Agent" set, requests now flew.
To x.com it goes, browser disguise on,
Parsing and posting until migration is gone.
In the warren of code, stealthy and spry,
The rabbit ensures requests comply! 🐇✨

<issue_to_address>
Repeatedly setting the same User-Agent header may be redundant.

If the User-Agent value remains constant, set it once at the start to simplify the code and reduce redundancy.

11-12: Eliminate hardcoded User-Agent duplication and align with existing patterns.

The same User-Agent string is hardcoded multiple times in this function, and it doesn't follow the existing pattern of using randomly generated User-Agent strings to prevent account banning.

Based on the retrieved learnings, the codebase uses randomly generated User-Agent strings. Consider using the existing User-Agent generation approach:

+    # Use existing User-Agent if available, or set a consistent default
+    if "User-Agent" not in headers:
+        headers["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 Chrome/128.0.0.0 Safari/537.36"
-    # Set User-Agent header once at the start
-    headers["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 Chrome/128.0.0.0 Safari/537.36"

27-27: Remove redundant User-Agent assignment.

This is the same hardcoded User-Agent string set earlier in the function, creating unnecessary duplication.

Since the User-Agent header is already set in the headers dictionary and persists across requests, this line can be removed:

-        headers["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 Chrome/128.0.0.0 Safari/537.36"

22-22: Remove unnecessary f-string prefix.

The f-string has no placeholders and should be a regular string.

-    migration_form = home_page.select_one("form[name='f']") or home_page.select_one(f"form[action='https://x.com/x/migrate']")
+    migration_form = home_page.select_one("form[name='f']") or home_page.select_one("form[action='https://x.com/x/migrate']")
