よくある思い込み

Req preserves Authorization headers across cross-origin redirects by default, retains the POST method when following 301 and 302 redirects, and sends no automatic accept-encoding headers unless compressed is requested.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• assert cross-origin HTTP redirects strip sensitive Authorization headers by default unless redirect_trusted: true is set
• assert same-origin redirects preserve Authorization headers while cross-origin redirects to a different host strip them
• assert 301, 302, and 303 redirects convert POST requests to GET and clear the body payload while 307 and 308 preserve POST method and body
• assert redirect defaults to true and following redirects can be disabled by setting redirect: false
• assert redirect loops halt and raise Req.TooManyRedirectsError when exceeding max_redirects default of 10
• assert compressed defaults to false and leaves accept-encoding unset, while compressed: true advertises supported encodings including gzip
• assert put_user_agent uses a Req version header by default and raises FunctionClauseError when user_agent: false is treated as a non-binary header value
