これまではHTTPリクエストについてでしたが
that's the basic HTTP requests now let's
ここからはHTTPレスポンスについてお話します
talk a little bit about HTTP responses
流れを簡単に図にまとめてみましょう
let's talk about where we are first you've got you and your machine and
あなたのコンピュータとサーバがあり
you've got these servers your browser
ブラウザがサーバにリクエストを送信します
makes a request to the servers and your
するとサーバはブラウザにレスポンスを返します
server sends back the response we talked about the requests already and the
サーバのレスポンスにはリクエストした文書や
server responds with a response the
それに応じた文書に関する情報が含まれます
document that you requested or you know information about the document depending
基本的なHTTPレスポンスは[br]リクエストとよく似た形をしています
on what you requested a basic HTTP response looks actually very similar to
こちらがリクエストで こちらがレスポンスです
the request for basically request that looks like this the response might look
3つの要素が含まれています
something like this okay so we can see a
まず始めにこれはステータスラインと呼ばれるもので
couple easy things first of all the stat this is called the status line and this
このリクエストラインに対応しています
is analogous to the request line we had
ステータスラインのバージョンは
over here now the version of the status
リクエストラインのものと一致しています
line matches the version of the request
そして残る2つの情報が後ろに続きます
line and then it's followed by two other pieces of information one is the status
ステータスコードとリーズンフレーズです
code and the other is the reason phrase
リーズンフレーズはステータスコードの説明文です
and this is just an English language description of the status code there are
ステータスコードにはいくつか一般的なものがあります
some really common status codes and I'll
200 OKは文書が見つかったという意味です
show you some of them here 200 okay that means the document is found this is a
通常であればこのコードが表示されるはずです
far and away the most common status code
302 Foundはリクエストした文書が[br]別の場所にある場合に表示されます
on the Internet and hopefully we'll be seeing a lot of these 302 found that means the document is located somewhere
404 Not foundは見覚えがある人もいると思います
else 404 not found you've probably seen
文書が見つからなかったことを表します
this one a lot this means the document wasn't found and 500 server error that
そして500 Server Errorは
means the server broke trying to handle
リクエスト実行時にサーバが中断したことを意味します
your request unfortunately we will
残念ながらこのコードもよく見かけます
probably also be seeing a fair number of
ステータスコードは基本的に1～5の数字から始まります
these and our adventures in this course status codes basically begin with one
2から始まるコードだと
two three four or five if it begins with
基本的にリクエストは成功です
the two basically means success if it
3から始まるコードは
begins with a three it basically means we need to do something different
追加の作業が必要なことを示します
technically to find this document four
4から始まるコードはブラウザの問題で
means there's an error on the browser
存在しない文書をリクエストしているときなどです
side requesting a document that doesn't exist for example and five means there's
5から始まるコードだと サーバの中断などのサーバ側の問題を示しています 次はレスポンスについてさらに詳しく見ていきます
an error on the server side such as the server is broken ok let's let's move on a little bit and talk a little bit more about responses
