Add advanced copy with content-type conversion by Copilot · Pull Request #7 · tomek7667/Copy-Request

Copilot · 2026-01-05T13:58:01Z

Adds "Advanced..." menu option to convert request bodies between content-types (JSON, form-urlencoded, and multipart) while automatically updating the Content-Type header.

Changes

Content-type converter (content_type_converter.py)
- Bidirectional conversion between application/json, application/x-www-form-urlencoded, and multipart/form-data
- URL encoding/decoding with bounds checking
- Simplified _from_dict method to remove redundant conditional branches
RequestTree enhancement (request_tree.py)
- Added optional target_content_type parameter
- Automatic body conversion and header update when target differs from source
- Support for multipart/form-data conversions
- Fixed bounds checking in _url_decode to prevent IndexError on malformed input
UI addition (main.py)
- "Advanced..." menu item in "more..." submenu
- Dialog format: <content-type-number>,<language> (e.g., 1,js or 2,python)
- Error handling for invalid input
- SUPPORTED_LANGUAGES constant for centralized language configuration
Tests
- 8 tests for content-type converter (including multipart support)
- 3 tests for RequestTree conversion
- 4 integration tests covering JS/Python × JSON/form combinations

Usage

Right-click request → Extensions > Copy Request > more > Advanced...
Enter: 2,js (converts to form-urlencoded, outputs JavaScript)
Enter: 3,python (converts to multipart, outputs Python)

Original JSON request:

{"username": "test", "password": "secret"}

Generates code with converted body and updated header:

// Content-Type: application/x-www-form-urlencoded
const stringifiedBody = constructXWwwFormUrlencoded(body);

make this much shorter paragraph will be sufficient

Simplified to a single paragraph in b54e767

all these ifs return the sama data_dict...

Fixed - simplified to return data_dict directly since all formats use dict internally in b54e767

That's bad. Multipart should be supported too.

Added multipart/form-data support in b54e767

If you need supported langs, dont hardcode, make them globally available from one place and access from it

Added SUPPORTED_LANGUAGES constant at module level in b54e767
