faradayを選んでみた，faradayで検索してこちらを見つけた．
quick guideがあったので読んでみる．

kai-matsudate commented

ガイドの通り，ローカルでgem install faradayを実行してみた．
以下のログが出た．

readmeを読んで，以下のコードを書いた．

require 'faraday'

response = Faraday.get('http://httpbingo.org')

puts response.status
puts response.headers
puts response.body

<h2 id="DESCRIPTION">DESCRIPTION</h2>

<p>Testing an HTTP Library can become difficult sometimes. <a href="http://requestb.in">RequestBin</a> is fantastic for testing POST requests, but doesn't let you control the response. This exists to cover all kinds of HTTP scenarios. Additional endpoints are being considered.</p>

<p>All endpoint responses are JSON-encoded.</p>

readmeを読み進めた．
3rd partyのAPIを利用する際は，connectionクラスを利用すると便利と書いてある．
quick guide記載の以下のコードを実行してみることにした．

conn = Faraday.new(
  url: 'http://httpbingo.org',
  params: {param: '1'},
  headers: {'Content-Type' => 'application/json'}
)

response = conn.post('/post') do |req|
  req.params['limit'] = 100
  req.body = {query: 'chunky bacon'}.to_json
end
# => POST http://httpbingo.org/post?param=1&limit=100
kai-matsudate commented

実行したら，以下のように標準エラー出力が出た．

connection_init.rb:1:in `<main>': uninitialized constant Faraday (NameError)

conn = Faraday.new(
       ^^^^^^^

先ほどは自前で require 'faraday'を追加していたが，今回はうっかり忘れてしまったので，こけている．

kai-matsudate commented

上記はサンプルコードにrequire 'faraday'がないため起きている事象なので，readmeに注意書きがあると初学者にはわかりやすいかもしれないと感じた．

kai-matsudate commented

同様のissueを探したが，見つからなかった．
https://github.com/lostisland/faraday/issues?page=7&q=is%3Aissue+require

kai-matsudate commented

引き続きreadmeを読んでいるが，全部叩くのは面倒なのでツラっと読んでみる．

kai-matsudate commented 
response = conn.get('get', { boom: 'zap' }, { 'User-Agent' => 'myapp' })
# => GET http://httpbingo.org/get?boom=zap

上記のコードが貼られていたが，これはconn(Faraday::Connectionのインスタンス)の初期化を前提としている．
しかし，ドキュメント構成は以下の画像のようになっており，

スクリーンショット 2024-04-18 11 45 58

どちらもh3要素なので同じ区分だと分かりずらい．

faradayの強みはmiddlewareらしい．
以下のスクリプトを書いて実行した．

  # Calls MyAuthStorage.get_auth_token on each request to get the auth token
  # and sets it in the Authorization header with Bearer scheme.
  builder.request :authorization, 'Bearer', -> { MyAuthStorage.get_auth_token }

  # Sets the Content-Type header to application/json on each request.
  # Also, if the request body is a Hash, it will automatically be encoded as JSON.
  builder.request :json

  # Parses JSON response bodies.
  # If the response body is not valid JSON, it will raise a Faraday::ParsingError.
  builder.response :json

  # Raises an error on 4xx and 5xx responses.
  builder.response :raise_error

faraday自身はHTTPリクエストを送信しておらず，adapterに任せているらしい．
デフォルトはNet::HTTPであり，自由に変更ができるとのこと．
以下の例が記載されていた．

conn = Faraday.new(url: 'http://httpbingo.org') do |builder|
  builder.adapter :async_http
end
kai-matsudate commented

<h2 id="DESCRIPTION">DESCRIPTION</h2>

<p>Testing an HTTP Library can become difficult sometimes. <a href="http://requestb.in">RequestBin</a> is fantastic for testing POST requests, but doesn't let you control the response. This exists to cover all kinds of HTTP scenarios. Additional endpoints are being considered.</p>

<p>All endpoint responses are JSON-encoded.</p>

asyncの開発者の別のリポジトリのissueが解決されていたので読んでみる

kai-matsudate commented

よくみたら同じGemを内部で使っていて同じ事象が起きていた．

kai-matsudate commented

何したらいいかわからなくなってきた

kai-matsudate commented

業務で使ったautocomplete.jsというvanilla jsのライブラリに一旦変えてみる．
https://github.com/TarekRaafat/autoComplete.js
Apache-2.0 licenseであることを確認．

kai-matsudate commented

リポジトリのreadmeを参照．

以下のwarningを確認．

しょうがないので，業務上ででくわした以下のバグを報告する．

autocompleteの候補が変な場所に出てくる．

kai-matsudate commented

上記の再現手順を確認して，可能であればPRとしてあげる．
時間内で厳しければIssueとしてあげることにした．

kai-matsudate commented

別環境で再現できなさそうで辛い．

kai-matsudate commented

いうて再現状況が結構限定的な気もするので，報告する必要性もない気がしてきた．

kai-matsudate commented

別にバグではなかった．非常に残念．

kai-matsudate commented

faradayのやつだけ報告して終わるか．

もうちょっとマシなFBできないか探索だけしてみる．

Basic Info

  • Faraday Version: 2.9.0
  • Ruby Version: 3.2.2

Issue description

When you access to this page, could not see home-logo image, like following.

スクリーンショット 2024-04-18 15 36 16

Seems to be it is local relative path, so you have to change image path like below.
