data.GetCSV

假設有以下目錄結構：

my-project/
└── other-files/
    └── pets.csv

可使用下列任一方式來存取資料：

{{ $data := getCSV "," "other-files/pets.csv" }}
{{ $data := getCSV "," "other-files/" "pets.csv" }}

存取遠端資料可使用下列任一方式：

{{ $data := getCSV "," "https://example.org/pets.csv" }}
{{ $data := getCSV "," "https://example.org/" "pets.csv" }}

結果資料結構為二維陣列：

[
  ["name","type","breed","age"],
  ["Spot","dog","Collie","3"],
  ["Felix","cat","Malicious","7"]
]

選項

提供選項映射來新增請求標頭：

{{ $opts := dict "Authorization" "Bearer abcd" }}
{{ $data := getCSV "," "https://example.org/pets.csv" $opts }}

使用切片新增多個標頭：

{{ $opts := dict "X-List" (slice "a" "b" "c") }}
{{ $data := getCSV "," "https://example.org/pets.csv" $opts }}

全域資源替代方法

存取全域資源時，建議使用 resources.Get 函式搭配 transform.Unmarshal。

my-project/
└── assets/
    └── data/
        └── pets.csv

{{ $data := dict }}
{{ $p := "data/pets.csv" }}
{{ with resources.Get $p }}
  {{ $opts := dict "delimiter" "," }}
  {{ $data = . | transform.Unmarshal $opts }}
{{ else }}
  {{ errorf "無法取得資源 %q" $p }}
{{ end }}

頁面資源替代方法

存取頁面資源時，建議使用 Resources.Get 方法搭配 transform.Unmarshal。

my-project/
└── content/
    └── posts/
        └── my-pets/
            ├── index.md
            └── pets.csv

{{ $data := dict }}
{{ $p := "pets.csv" }}
{{ with .Resources.Get $p }}
  {{ $opts := dict "delimiter" "," }}
  {{ $data = . | transform.Unmarshal $opts }}
{{ else }}
  {{ errorf "無法取得資源 %q" $p }}
{{ end }}

遠端資源替代方法

存取遠端資源時，建議使用 resources.GetRemote 函式搭配 transform.Unmarshal，以改善錯誤處理和快取控制。

{{ $data := dict }}
{{ $u := "https://example.org/pets.csv" }}
{{ with resources.GetRemote $u }}
  {{ with .Err }}
    {{ errorf "%s" . }}
  {{ else }}
    {{ $opts := dict "delimiter" "," }}
    {{ $data = . | transform.Unmarshal $opts }}
  {{ end }}
{{ else }}
  {{ errorf "無法取得遠端資源 %q" $u }}
{{ end }}
