使用 JavaScript 函式處理憑證回應

處理憑證回應

您可以在 data-callback 屬性中設定 JavaScript 函式，以便處理傳回的憑證回應。請參閱下列程式碼片段：

<div id="g_id_onload"
     data-client_id="YOUR_GOOGLE_CLIENT_ID"
     data-callback="handleCredentialResponse">
</div>
<script>
  function handleCredentialResponse(response) {
     // decodeJwtResponse() is a custom function defined by you
     // to decode the credential response.
     const responsePayload = decodeJwtResponse(response.credential);

     console.log("ID: " + responsePayload.sub);
     console.log('Full Name: ' + responsePayload.name);
     console.log('Given Name: ' + responsePayload.given_name);
     console.log('Family Name: ' + responsePayload.family_name);
     console.log("Image URL: " + responsePayload.picture);
     console.log("Email: " + responsePayload.email);
  }
</script>

您可以使用適用於您語言的 JWT 解碼程式庫，驗證及解碼 JWT 憑證。您也應在伺服器端驗證 Google ID 權杖。
