使用 HTTP 託管靜態網站

本教學課程說明如何設定 Cloud Storage 值區來代管您網域的靜態網站。靜態網頁可能會採用一些用戶端技術，包括 HTML、CSS 和 JavaScript 等等。且不得包含伺服器端指令碼 (如 PHP) 的動態內容。

本教學課程說明如何透過 HTTP 提供內容。如需使用 HTTPS 的教學課程，請參閱託管靜態網站。

如需靜態網頁的範例和提示，包括如何託管動態網站的靜態資產，請參閱靜態網站頁面。

將網域連線至 Cloud Storage

如要將網域連線至 Cloud Storage，請透過網域註冊服務建立 CNAME 記錄。CNAME 記錄是一種 DNS 記錄類型，可以將從您網域要求網址的流量導向要提供的資源，在本例則是指 Cloud Storage 值區內的物件。如果是 www.example.com，CNAME 記錄可能包含下列資訊：

NAME                  TYPE     DATA
www                   CNAME    c.storage.googleapis.com.

如需有關 CNAME 重新導向的詳細資訊，請參閱 CNAME 別名的 URI。

將網域連線至 Cloud Storage 的方式如下：

建立指向 c.storage.googleapis.com. 的 CNAME 記錄。

您的網域註冊服務應該會支援您管理網域 (包括新增 CNAME 記錄)。舉例來說，如果您使用 Cloud DNS，可以在「新增、修改及刪除記錄」頁面查看新增資源記錄的操作說明。

附註：DNS 不支援在根網域上建立 CNAME 記錄，例如 example.com，因此多數情況下，您都必須在子網域上建立 CNAME 記錄，如 www.example.com 或 myblog.example.com。某些 DNS 供應商提供的非標準功能，可讓根網域在不使用 CNAME 的情況下使用另一個名稱當做別名。請參閱您的 DNS 供應商說明文件，瞭解這項功能是否可供使用。

建立值區

建立值區時，名稱應符合您為網域建立的 CNAME。

舉例來說，如果您新增了一個將 example.com 的 www 子網域指向 c.storage.googleapis.com. 的 CNAME 記錄，則使用 Google Cloud CLI 建立名稱為 www.example.com 的值區時，指令會類似於下列範例：

gcloud storage buckets create gs://www.example.com --location=US

如需使用不同工具建立值區的完整操作說明，請參閱建立值區。

上傳網站檔案

將您想讓網站提供的檔案新增到值區內：

控制台

在 Google Cloud 控制台，前往「Cloud Storage bucket」頁面。

前往「Buckets」(值區) 頁面
在值區清單中，按一下您建立的值區名稱。
按一下「Objects」(物件) 分頁中的 [Upload files] (上傳檔案) 按鈕。
在檔案對話方塊中，找出並選取您需要的檔案。

上傳完成後，您應該會看到檔案名稱與值區中顯示的檔案資訊。

指令列

使用 gcloud storage cp 指令將檔案複製到您的 bucket。例如，假設您要從目前的位置 Desktop 複製 index.html：

gcloud storage cp Desktop/index.html gs://www.example.com

如果成功，回應會類似以下範例：

Completed files 1/1 | 164.3kiB/164.3kiB

REST API

JSON API

安裝並初始化 gcloud CLI，以便為 Authorization 標頭產生存取權杖。

使用 cURL 透過 POST 物件要求呼叫 JSON API。對於 www.example.com 的索引頁面：

curl -X POST --data-binary @index.html \
  -H "Content-Type: text/html" \
  -H "Authorization: $(gcloud auth print-access-token)" \
  "https://storage.googleapis.com/upload/storage/v1/b/www.example.com/o?uploadType=media&name=index.html"

XML API

安裝並初始化 gcloud CLI，以便為 Authorization 標頭產生存取權杖。

使用 cURL 透過 PUT 物件要求呼叫 XML API。對於 www.example.com 的索引頁面：

curl -X PUT --data-binary @index.html \
  -H "Authorization: $(gcloud auth print-access-token)" \
  -H "Content-Type: text/html" \
  "https://storage.googleapis.com/www.example.com/index.html"

如要將 bucket 中的所有物件設為可供公開網路中的所有使用者讀取，請按照下列步驟操作：

控制台

在 Google Cloud 控制台，前往「Cloud Storage bucket」頁面。

前往「Buckets」(值區) 頁面
在值區清單中，找到您要設為公開的值區名稱，然後點選這個名稱。
選取靠近頁面上方的 [Permissions] (權限) 分頁標籤。
如果「公開存取權」窗格顯示「非公開」，請點選標示為「移除禁止公開存取功能」的按鈕，然後在隨即顯示的對話方塊中點選「確認」。
按一下「授予存取權」按鈕。

系統隨即會顯示「新增主體」對話方塊。
在「New principals」(新增主體) 欄位中輸入 allUsers。
在「請選擇角色」下拉式選單中，選取「Cloud Storage」子選單，然後點選「Storage 物件檢視者」選項。
按一下 [儲存]。
按一下「Allow public access」(允許公開存取)。

公開共用後，「public access」(公開存取權) 欄中會出現各個物件的連結圖示。點選這個圖示即可取得物件的網址。

REST API

JSON API

安裝並初始化 gcloud CLI，以便為 Authorization 標頭產生存取權杖。

建立包含下列資訊的 JSON 檔案：

{
  "bindings":[
    {
      "role": "roles/storage.objectViewer",
      "members":["allUsers"]
    }
  ]
}

使用 cURL 透過 PUT Bucket 要求呼叫 JSON API：

curl -X PUT --data-binary @JSON_FILE_NAME \
  -H "Authorization: Bearer $(gcloud auth print-access-token)" \
  -H "Content-Type: application/json" \
  "https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/iam"

其中：

JSON_FILE_NAME 是您在步驟 2 建立的 JSON 檔案路徑。
BUCKET_NAME 是要將物件設為公開的值區名稱。例如：my-bucket。

XML API

XML API 不支援將值區中的所有物件設為可公開讀取，請改用 Google Cloud 控制台或 gcloud storage。

如有需要，您也可以將部分值區設為公開存取。

針對非公開或不存在的檔案要求網址時，訪客會收到 http 403 回應碼。請參閱下一節，進一步瞭解如何新增顯示使用 http 404 回應碼的錯誤網頁。

建議採用：指派專用頁面

您可以指派索引頁面的尾碼 (由 MainPageSuffix 資源控制) 及自訂錯誤網頁 (由 NotFoundPage 資源控制)。雖然不一定要指派，但如果沒有索引頁面，使用者存取您的頂層網站 (例如 http://www.example.com) 時就不會看到任何內容。詳情請參閱網站設定範例。

在下列範例中，會將 MainPageSuffix 設定為 index.html，而 NotFoundPage 設定為 404.html：

控制台

在 Google Cloud 控制台，前往「Cloud Storage bucket」頁面。

前往「Buckets」(值區) 頁面
在值區清單中，找到您建立的值區。
按一下與值區相關聯的「Bucket overflow」(值區溢位) 選單 ()，然後選取「Edit website configuration」(編輯網站設定)。
在網站設定對話方塊中，指定主網頁和錯誤頁面。
按一下 [儲存]。

指令列

使用加上 --web-main-page-suffix 和 --web-error-page 旗標的 buckets update 指令：

gcloud storage buckets update gs://www.example.com --web-main-page-suffix=index.html --web-error-page=404.html

如果執行成功，指令會傳回下列內容：

Updating gs://www.example.com/...
  Completed 1

REST API

JSON API

安裝並初始化 gcloud CLI，以便為 Authorization 標頭產生存取權杖。

建立 JSON 檔案，將 website 物件中的 mainPageSuffix 和 notFoundPage 屬性設為需要的網頁：

{
  "website":{
    "mainPageSuffix": "index.html",
    "notFoundPage": "404.html"
  }
}

使用 cURL 透過 PATCH 值區要求呼叫 JSON API。以 www.example.com 為例：

curl -X PATCH --data-binary @web-config.json \
  -H "Authorization: $(gcloud auth print-access-token)" \
  -H "Content-Type: application/json" \
  "https://storage.googleapis.com/storage/v1/b/www.example.com"

XML API

安裝並初始化 gcloud CLI，以便為 Authorization 標頭產生存取權杖。

建立 XML 檔案，將 WebsiteConfiguration 元素中的 MainPageSuffix 和 NotFoundPage 元素設為需要的網頁：

<WebsiteConfiguration>
  <MainPageSuffix>index.html</MainPageSuffix>
  <NotFoundPage>404.html</NotFoundPage>
</WebsiteConfiguration>

使用 cURL 透過 PUT 值區要求和 websiteConfig 查詢字串參數呼叫 XML API。以 www.example.com 為例：

curl -X PUT --data-binary @web-config.xml \
  -H "Authorization: $(gcloud auth print-access-token)" \
  https://storage.googleapis.com/www.example.com?websiteConfig

測試網站

在瀏覽器中要求網域名稱，驗證內容是從值區提供。如果您已經設定 MainPageSuffix 資源，可以使用物件路徑或單用網域名稱來進行驗證。

舉例來說，若有名為 test.html 的物件儲存在命名為 www.example.com 的值區，請在瀏覽器中查看 www.example.com/test.html，檢查是否可存取該物件。

使用 HTTP 託管靜態網站 透過集合功能整理內容 你可以依據偏好儲存及分類內容。
