安全上下文
此特征只可用于 安全上下文 (HTTPS)，在某些或所有 支持浏览器 .

userVerification is an optional property of the PublicKeyCredentialRequestOptions . This is a string which indicates how the user verification should be part of the authentication process.

注意： An analogous option exists for the creation operation ( navigators.credentials.create() ), see the userVerification property of PublicKeyCredentialCreationOptions.authenticatorSelection .

句法

userVerification = publicKeyCredentialRequestOptions.userVerification
					

值

A string qualifying how the user verification should be part of the authentication process. The values may be:

• "required" : user verification is required, the operation will fail if the response does not have the UV flag (as part of AuthenticatorAssertionResponse.authenticatorData )
• "preferred" : user verification is prefered, the operation will not fail if the response does not have the UV flag (as part of AuthenticatorAssertionResponse.authenticatorData )
• "discouraged" : user verification should not be employed as to minimize the user interaction during the process.

默认值为 "preferred" .

范例

var options = {
  userVerification: "preferred",
  challenge: new Uint8Array([/* bytes sent from the server */]),
};
navigator.credentials.get({ "publicKey": options })
    .then(function (credentialInfoAssertion) {
    // send assertion response back to the server
    // to proceed with the control of the credential
}).catch(function (err) {
     console.error(err);
});
