LINE - LINE 登入 - hoyo 學習紀錄

參考資訊

流程一：到開發者後台建立 LINE 登入的 App channel

登入 LINE Developers
建立或選擇 Provider
點選「Create new channel」 → 選擇「LINE Login」 → 填寫資料
切換「App settings」分頁，輸入 Callback URL 必須是 https://

流程二：使用程式取得登入後的 LINE 使用者 id

步驟

使用 https://access.line.me/oauth2/v2.1/authorize 取得 code，取得的方式是後台設定的 Callback URL
將取得的 code 丟給 https://api.line.me/oauth2/v2.1/token 來換 access_token
將 access_token 丟給 https://api.line.me/v2/profile 來取得使用者資料

範例：

發送以下網址

https://access.line.me/oauth2/v2.1/authorize?response_type=code&client_id=2009999994&redirect_uri=https://upad12.com/LineLoginCallback&state=xxxxxxx&scope=profile%20openid

1	https://access.line.me/oauth2/v2.1/authorize?response_type=code&client_id=2009999994&redirect_uri=https://upad12.com/LineLoginCallback&state=xxxxxxx&scope=profile%20openid

順利的話在後台設定的 Callback URL 就會得到類似

https://upad12.com/LineLoginCallback?code=r2ySgfyxxxxxxwArlEL&state=xxxxxxx

1	https://upad12.com/LineLoginCallback?code=r2ySgfyxxxxxxwArlEL&state=xxxxxxx

自己寫程式去撈 code 變數，將 code 丟給 token

curl -X POST https://api.line.me/oauth2/v2.1/token -H 'Content-Type: application/x-www-form-urlencoded' -d 'grant_type=authorization_code' -d 'code=r2ySgfyxxxxxxwArlEL' -d 'redirect_uri=https://upad12.com/LineLoginCallback' -d 'client_id=2009999994' -d 'client_secret=3c3208e66666666666edc1211c0051b6'

curl -X POST https://api.line.me/oauth2/v2.1/token -H 'Content-Type: application/x-www-form-urlencoded' -d 'grant_type=authorization_code' -d 'code=r2ySgfyxxxxxxwArlEL' -d 'redirect_uri=https://upad12.com/LineLoginCallback' -d 'client_id=2009999994' -d 'client_secret=3c3208e66666666666edc1211c0051b6'

順利的話可以得到類似

最後把 access_token 丟到 profile 取得登入使用者資料

curl -v -X GET https://api.line.me/v2/profile -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.GBSwhR_IGb9-jbzZni8ixxxxxxxxxHPHAU_pw3R4U07ITuI_HGOjjy4gAzJIxxxxxxxESciryN6G3sI_dPawXUC0uM9e8wBTs6xEKxw-4P1x22ibNmKG5OuCLcM2INgQAk5tuLwhrK5ZkxWPI.G2pC3NbgGPkE21cxgUhSxiry936a29zFJnA1KEQj3xA'

1	curl -v -X GET https://api.line.me/v2/profile -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.GBSwhR_IGb9-jbzZni8ixxxxxxxxxHPHAU_pw3R4U07ITuI_HGOjjy4gAzJIxxxxxxxESciryN6G3sI_dPawXUC0uM9e8wBTs6xEKxw-4P1x22ibNmKG5OuCLcM2INgQAk5tuLwhrK5ZkxWPI.G2pC3NbgGPkE21cxgUhSxiry936a29zFJnA1KEQj3xA'

?後面接上參數，說明如下

參數	類型	必填？	描述
`response_type`	字串	必填	`code`
`client_id`	字串	必填	LINE登錄頻道ID。您可以在LINE開發者控制台中找到它。
`redirect_uri`	字串	必填	在LINE開發者控制台上註冊的回調URL的URL編碼字串。您可以新增任何查詢參數。
`state`	字串	必填	用於防止的唯一字母數位字串跨站請求偽造（開啟新視窗）.Web 應用應為每個登錄會話生成一個隨機值。這不能是 URL 編碼的字串。
`scope`	字串	必填	從使用者請求的許可權。有關詳細資訊，請參閱作用域。

如果需要傳遞額外的參數，就附加在 redirect_uri 上，例如要和帳號綁定 LINE 帳號需要 user_id，那就可以在網址後面加上 ?user_id=xxxx 這樣傳遞，不過後面 token 的 redirect_uri 也要相同

scope 說明

Scope	Profile information	ID token (including user ID)	Display name in ID token	Profile image URL in ID token	Email address in ID token
`profile`	✓	-	-	-	-
`profile%20openid`	✓	✓	✓	✓	-
`profile%20openid%20email`	✓	✓	✓	✓	✓ (see note)
`openid`	-	✓	-	-	-
`openid%20email`	-	✓	-	-	✓ (see note)

登入開始需要用程式來處理一些參數，例如 state ，當然固定值也可以

如果 redirect_uri 有特殊字元 ? & 就需要使用 urlencode() 來編碼

<a href="https://access.line.me/oauth2/v2.1/authorize?response_type=code&amp;client_id=2005611794&amp;redirect_uri=https%3A%2F%2Fupad12.com%2FLineLoginCallback%3Faction%3Dbind&amp;state=666be51e8c72c&amp;scope=profile%20openid">進行綁定</a>

https://api.line.me/oauth2/v2.1/token

grant_type	authorization_code
code	從 LINE 平台收到的授權碼
redirect_uri	與授權請求redirect_uri中指定的值相同。
client_id	在LINE 開發者控制台中找到。
client_secret	在LINE 開發者控制台中找到。
