HTTP リクエスト
GET https://www.googleapis.com/youtube/v3/playlistItems
パラメータ
下記の表は、このクエリでサポートされているパラメータの一覧です。このリストのパラメータはすべてクエリ パラメータです。
パラメータ | ||
---|---|---|
必須パラメータ | ||
part |
string part パラメータには、API レスポンスに含める 1 つまたは複数の playlistItem リソース プロパティをカンマ区切りリストの形式で指定します。このパラメータ値に指定できる part 名は id 、snippet 、contentDetails 、status などです。このパラメータに子プロパティを持つプロパティが指定されている場合、その子プロパティもレスポンスに含まれます。たとえば playlistItem リソースの snippet プロパティは、title 、description 、position 、resourceId プロパティなどの複数のフィールドを持ちます。この場合、part=snippet と設定すると、API レスポンスにはこれらのプロパティすべてが含まれることになります。 |
|
フィルタ(以下のパラメータのいずれか 1 つのみを指定します) | ||
id |
string id パラメータには、1 つまたは複数の一意の再生リスト アイテム ID をカンマ区切りリストの形式で指定します。 |
|
playlistId |
string playlistId パラメータには、再生リスト アイテムを取得する再生リストの一意の ID を指定します。このパラメータは省略可能ですが、再生リスト アイテムを取得するためのすべてのリクエストには id パラメータまたは playlistId パラメータのいずれかの値を指定する必要があることに注意してください。 |
|
省略可能なパラメータ | ||
maxResults |
unsigned integer maxResults パラメータには、結果セットで返されるアイテムの最大数を指定します。0 以上 50 以下の値を指定できます。デフォルト値は 5 です。 |
|
pageToken |
string pageToken パラメータには、返される結果セットに含める特定のページを指定します。API レスポンスでは、nextPageToken と prevPageToken プロパティは取得可能な他のページを表します。 |
|
videoId |
string videoId パラメータでは、指定した動画を含む再生リスト アイテムだけをリクエストによって返すことを指定します。 |
リクエストの本文
このメソッドを呼び出す場合は、リクエストの本文を指定しないでください。
レスポンス
成功すると、このメソッドは次の構造を持つレスポンスの本文を返します。
{ "kind": "youtube#playlistItemListResponse", "etag": etag, "nextPageToken": string, "prevPageToken": string, "pageInfo": { "totalResults": integer, "resultsPerPage": integer }, "items": [ playlistItems リソース ] }
プロパティ
次の表は、このリソースで使用されているプロパティの定義を示したものです。
プロパティ | |
---|---|
kind |
string API リソースのタイプ。値は youtube#playlistItemListResponse です。 |
etag |
etag このリソースの Etag。 |
nextPageToken |
string 結果セットの次のページを取得するために、 pageToken パラメータの値として使用できるトークン。 |
prevPageToken |
string 結果セットの前のページを取得するために、 pageToken パラメータの値として使用できるトークン。 |
pageInfo |
object pageInfo オブジェクトは、結果セットのページング情報をカプセル化します。 |
pageInfo.totalResults |
integer 結果セット内の結果の総数。 |
pageInfo.resultsPerPage |
integer API レスポンスに含まれる結果の数。 |
items[] |
list リクエスト条件と一致する再生リスト アイテムのリスト。 |
