如何修复 JS 错误:用户代理不支持公钥凭据

Gid*_*abu 5 javascript webauthn

我正在使用新的PasswordCredential API 并创建了这段代码。它正在发挥作用。但对于某些用户来说,它会抛出此错误The user agent does not support public key credentials.

if (window.PasswordCredential) {
    navigator.credentials.get({
        password: true,
        mediation: 'optional'
    }).then(credential => {
        if (credential) {
        if (credential.type === 'password') {
            // authenticate the user with obtained credentials
        }
    });
}

尽管我没有使用该 API,但许多用户都会遇到该错误。那么,我应该像这样检查这两个条件吗:

if (window.PasswordCredential && typeof(PublicKeyCredential) != "undefined" ) {

如果是这样,我为什么要对两者都进行此检查?
