Chrome DevTools 协议 WebAuthn.addCredential 返回错误

Question

我正在尝试在 Cypress 测试中调用 Chrome DevTools 协议 WebAuthn.addCredential 方法。

credential = {
    credentialId:"myid",
    isResidentCredential: true,
    rpId:"localhost",
    userHandle: "bXl1c2VyaGFuZGxlDQo=",
    privateKey: "my_private_key",
    signCount: 0,
  }

Cypress.automation('remote:debugger:protocol', {
  command: 'WebAuthn.addCredential',
  params: {
    authenticatorId: authenticatorId,
    credential,
  },
})

但是，这会引发一个非常无用的错误：

有什么想法可能是错的吗？我按照here

给出的说明创建了私钥

Answer 1

弄清楚出了什么问题，是私钥出了问题，尽管我不知道是什么。在尝试通过互联网创建一对可用的私钥-公钥并失败后，这就是我所做的：

使用我的 Cypress 测试进行 WebAuthn 注册（我已经完成并且正在工作），我使用

navigator.credentials.create()

创建了凭证。然后我添加了一个额外的测试步骤，使用 Chrome DevTools Protocol

WebAuthn.getCredentials

命令获取虚拟 Web 身份验证器凭据，并打印结果。这给了我私钥。然后，完成测试后，我进入测试数据库并检查为注册测试的用户创建的 webauthn 记录。这给了我公钥。
