我正在开发一个nodejs应用程序并使用passportjs进行身份验证.我正在使用当地的护照策略.但是当我尝试登录时,我收到以下错误:

Error: Unknown authentication strategy "local"
    at attempt (/home/project/node_modules/passport/lib/middleware/authenticate.js:166:37)
    at authenticate (/home/project/node_modules/passport/lib/middleware/authenticate.js:338:7)

这是我的passport-config.js文件:

var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var User = require('../models/user');

passport.serializeUser(function(user, done) {
  done(null, user.id);
});

passport.deserializeUser(function(id, done) {
  User.findById(id, function (err, user) {
    done(err, user);
  });
});

passport.use({usernameField: 'emailAddress'}, new LocalStrategy(function(username, password, done) {
  User.findOne({ emailAddress: username }, function(err, user) { …

我正在使用mongoose ODM开发一个使用mongodb的节点应用程序.我在类型引用驻留在不同文件中的模式时收到错误.

我在user.js文件中有以下代码:

var mongoose = require('mongoose');
var Trip = require('./trip');

var userSchema = mongoose.Schema({
    firstName: String,
    lastName: String,
    salt: String,
    hash: String,
    emailAddress: {
        type: String,
        unique: true
    },
    trips: [{Type: mongoose.Schema.Types.ObjectId, ref: 'Trip'}]
});

module.exports = mongoose.model('User', userSchema);

userSchema具有对tripSchema的类型引用.

我的trip.js文件中的代码是:

    var tripSchema = mongoose.Schema({
      name: String,
      location: String,
      arrivalDate: Date,
      departureDate: Date,
      type: String});

   module.exports = mongoose.model('Trip', tripSchema);

当我运行该应用程序时,我收到以下错误:

    /usr/lib/node_modules/mongoose/lib/schema.js:360
    throw new TypeError('Undefined type at `' + path +
          ^
TypeError: Undefined type at `trip.ref`
  Did you try …

我们使用nginx服务器来反向代理很少的微服务.每个请求都Authorization包含包含JWT令牌的标头.现在,我们需要做的是从JWT令牌中提取用户详细信息并将其记录在nginx服务器上.无论如何解码和登录JWT？我查看了几个用于使用JWT验证请求的lua脚本,但这不是我们需要的.此外,我们试图避免在nginx服务器上安装Lua.

任何帮助将不胜感激.

编辑:我们也很适合基于Lua的解决方案.

我想在我的Android应用程序中集成G​​oogle Plus登录.当我尝试在Android Google API模拟器上运行此应用程序时,会出现一个对话框,提示我更新"Google Play服务".单击"更新"按钮没有任何反应,我可以在logcat中看到以下错误:

Can't redirect to app settings for Google Play services

我也在logcat中收到以下警告:

Google Play services out of date.  Requires 3225100 but found 3158130

另外我想补充一点,我已将Google Play服务从版本8更新到版本10.

有人可以告诉我如何在模拟器上更新Google Play服务吗？

我知道Stack Overflow上有很多关于这个主题的问题,但似乎没有什么对我有用.任何帮助将不胜感激.

我对GraphQL有问题。我想将axios.post请求发送到我的服务器。我可以用邮递员来做：

{
    "query":"mutation{updateUserCity(userID: 2, city:\"test\"){id name age city knowledge{language frameworks}}} "
}

在graphiql中：

mutation {
  updateUserCity(userID: 2, city: "test") {
    id
    name
    age
    city
    knowledge {
      language
      frameworks
    }
  }
}

但无法在我的代码中执行：（（（这是我的代码段：

const data = await axios.post(API_URL, {
  query: mutation updateUserCity(${ id }: Int!, ${ city }: String!) {
    updateUserCity(userID: ${ id }, city: ${ city }){
      id
      name
      age
      city
      knowledge{
        language
        frameworks
      }
    }
  }
}, {
    headers: {
      'Content-Type': 'application/json'
    }
  })

我的代码有什么问题？
