Node.js集成WireMock模拟Google OAuth流程时，获取用户信息失败的问题求助

我正在Node.js应用的集成测试中尝试用WireMock模拟Google OAuth的完整流程，但目前卡在了获取用户信息的环节，总是抛出InternalOAuthError: Failed to fetch user profile错误，想请大家帮忙看看我的配置哪里出了问题。

我的配置细节： #

1. Passport GoogleStrategy 配置

我在Passport管理代码里修改了GoogleStrategy的端点指向本地WireMock服务：

passport.use(new GoogleStrategy({
    clientID: config.googleAuth.clientID,
    clientSecret: config.googleAuth.clientSecret,
    callbackURL: config.googleAuth.callbackURL,
    passReqToCallback: true,
    authorizationURL: process.env.GOOGLE_AUTH_URL || 'https://accounts.google.com/o/oauth2/v2/auth',
    tokenURL: process.env.GOOGLE_TOKEN_URL || 'https://www.googleapis.com/oauth2/v4/token',
    userProfileURL: process.env.GOOGLE_USERINFO_URL || 'https://www.googleapis.com/oauth2/v3/userinfo',
}, authUser));

2. 环境变量设置（PowerShell）

我把三个OAuth相关的端点指向了本地WireMock的端口：

$env:GOOGLE_AUTH_URL = "http://localhost:8077/oauth/authorize"
$env:GOOGLE_TOKEN_URL = "http://localhost:8077/oauth/token"
$env:GOOGLE_USERINFO_URL = "http://localhost:8077/userinfo"

3. WireMock 启动与Stub配置

我通过Docker启动WireMock，然后用PowerShell配置了三个核心Stub（授权回调、令牌发放、用户信息）：

# 启动WireMock容器
docker run --rm -d -p 8077:8080 --name wiremock wiremock/wiremock:3.13.1
Start-Sleep -Seconds 5

# 配置/oauth/token的POST请求Stub，返回假令牌
$tokenStub = @{
    request = @{
        method = "POST"
        url = "/oauth/token"
    }
    response = @{
        status = 200
        jsonBody = @{
            access_token = "fake-access-token"
            token_type = "Bearer"
            expires_in = 3600
        }
    }
} | ConvertTo-Json -Depth 10
Invoke-RestMethod -Uri "http://localhost:8077/__admin/mappings" -Method Post -ContentType "application/json" -Body $tokenStub

# 配置/oauth/authorize的GET请求Stub，直接重定向到回调地址并携带假授权码
$authorizeStub = @"
{
  "request": {
    "method": "GET",
    "urlPath": "/oauth/authorize",
    "queryParameters": {
      "response_type": { "equalTo": "code" },
      "redirect_uri": { "contains": "localhost:3000/auth/google/callback" },
      "scope": { "contains": "profile" },
      "client_id": { "matches": ".*" }
    }
  },
  "response": {
    "status": 302,
    "headers": { "Location": "http://localhost:3000/auth/google/callback?code=fake-auth-code" }
  }
}
"@
Invoke-RestMethod -Uri "http://localhost:8077/__admin/mappings" `
-Method Post -ContentType "application/json" -Body $authorizeStub

# 配置/userinfo的GET请求Stub，返回假用户信息
$userinfoStub = @"
{
  "request": {
    "method": "GET",
    "url": "/userinfo",
    "headers": { "Authorization": { "matches": "(?i)^Bearer\\s+fake-access-token$" } }
  },
  "response": {
    "status": 200,
    "headers": { "Content-Type": "application/json" },
    "jsonBody": {
      "id": "mockuser-123456",
      "email": "mockuser@example.com",
      "name": "Mock User",
      "username": "mockuser-123456"
    }
  }
}
"@
Invoke-RestMethod -Uri "http://localhost:8077/__admin/mappings" -Method Post -ContentType "application/json" -Body $userinfoStub

遇到的错误 #

测试时触发的完整错误栈如下：

InternalOAuthError: Failed to fetch user profile
at ....\node_modules\passport-google-oauth20\lib\strategy.js:99:19
at passBackControl (....\node_modules\oauth\lib\oauth2.js:132:9)

我检查了WireMock的请求日志，发现/userinfo的Stub似乎根本没有被命中，怀疑是不是请求的匹配条件有问题？或者Passport在调用用户信息接口时还有什么我没考虑到的参数？
