目前,它在每个国家查询,但我希望它只在新加坡查询

我发现了一个stackoverflow解决方案如何使用Google自动完成位置api ios sdk获取特定国家/地区的结果？,但无法弄清楚我把代码放在哪里.

这是代码,我使用全屏解决方案进行自动完成.

import UIKit
import GoogleMaps

class OnlyLocationViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
                // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    @IBAction func clickMe(sender: UIButton) {
        let autocompletecontroller = GMSAutocompleteViewController()
        autocompletecontroller.delegate = self
        self.presentViewController(autocompletecontroller, animated: true, completion: nil)


    }

}

extension OnlyLocationViewController: GMSAutocompleteViewControllerDelegate{

    func viewController(viewController: GMSAutocompleteViewController, didAutocompleteWithPlace place: GMSPlace) {
        print("Place name: ", place.name)
        print("Place address: …

我正在探索不同的 websocket 库进行自学，我发现这个库真的很棒ws-node。我正在 ws-node 库中构建基本的一对一聊天

我的问题是ws 中的socket.io函数等价于什么？socket.to().emit()因为我想向特定用户发送消息。

前端 - socket.io

socket.emit("message", { message: "my name is dragon", userID: "123"});

服务器端-socket.io

// listening on Message sent by users
socket.on("message", (data) => {
    // Send to a specific user for 1 on 1 chat
    socket.to(data.userID).emit(data.message);
});

WS-- 后端

const express = require('express');
const http =  require('http');
const WebSocket = require('ws');
const express = require('express');
const http =  require('http');
const WebSocket = require('ws');

const app = express(); …

我在使用passport-instagram时遇到了麻烦,我正试图在我的应用程序中实施passport-instagram.每当我尝试使用instagram登录按钮登录时,我都会收到此错误:InternalOAuthError:无法获取访问令牌{无匹配代码}

这是代码

instagram.js(护照instagram配置文件)

var passport = require('passport');
var InstagramStrategy = require('passport-instagram').Strategy;
var User = require('../models/user');

var instaOpt = {
  clientID: "aad229e3597643be92568acb46efb40d",
  clientSecret: "5563070a33394e0fafada92a16ec2e71",
  callbackURL: "http://localhost:8000/auth/instagram/callback"
};

var instagramInit = function(accessToken, refreshToken, profile, callback) {
  User.findOne({ "instagram.id" : profile.id } , function(err, user) {
    if (err) return callback(err);

    if (user) {
      return callback(null, user); // User already exist
    }

    var newUser = new User();
    newUser.instagram.id = profile.id;
    newUser.instagram.token = accessToken;
    newUser.instagram.email = profile.email;
    newUser.instagram.displayName = profile.displayName;
    newUser.instagram.name = profile.name;
    newUser.instagram.username …

我的问题是，无论如何我都需要初始化该特定变量，因为还有另一个对象依赖于此变量的值

这是代码（我将变量设置为global）

lazy var getToken = {
        if let token = keychain["token"].string {
            return token
        }
    }()

我正在使用惰性，因为无论如何我都需要使用它来进行初始化。

当我尝试将其放在全局文件中时出现此错误错误

'lazy'可能不会在已经很懒惰的global上使用

这是取决于此令牌的对象

单例设计

class SocketIOManager: NSObject {

    static let sharedInstance = SocketIOManager()

    let socket: SocketIOClient!

    private override init() {
        super.init()
        socket = SocketIOClient(socketURL: URL(string: mainURL)!, .connectParams(["token": getToken])])
  }
}

如果你看看socket =在"token"，这就是我需要的令牌

所以我设法让passport-twitter与jsonwebtoken库一起工作,但为了使它正常工作,我必须使用express-session作为中间件.我不想添加会话因为我使用jsonwebtoken来返回令牌.

这是代码autheticate.js

router.get('/twitter', function(req, res, next){

  passport.authenticate('twitter', {session: false}, function(err, user, info){
    if(err){ return next(err); }

    if(user){
      var token = createToken(user);
      console.log(token);
      return res.json({token: token});
    } else {
      return res.status(401).json(info);
    }
  })(req, res, next);
});

我已经添加了session:false作为参数,但是在server.js上它保持吐出错误,我需要使用快速会话.

server.js

var express       = require('express');
var path          = require('path');
var logger        = require('morgan');
var bodyParser    = require('body-parser');
var mongoose      = require('mongoose');
var passport      = require('passport');
var session       = require('express-session');
var config        = require('./config');

mongoose.connect('mongodb://localhost', function() {
  console.log("Connected to the database");
})

require('./passport')(passport); …

我只是无法弄清楚为什么while循环中的这个简单逻辑不起作用.

基本上函数的作用是,它接受一个参数并检查while循环以查看它是否为"yes"或"no"然后继续循环.

void getAnswer(string answer) {

    string newAnswer = "";
    newAnswer = answer;
    while (newAnswer != "Yes" || newAnswer != "yes" || newAnswer != "Y" || newAnswer != "y" || newAnswer != "No" || newAnswer != "no") {
            cout << "Enter yes or no.." << endl;
            cin >> newAnswer;

        }

        if (newAnswer == "Yes" || newAnswer == "yes" || newAnswer == "Y" || newAnswer == "y") {
            chooseOptions();
        } else {
            cout << "Bye See you again " << endl; …

我已经使用node.js实现了条带结账

product.photo是https://test.s3.amazonaws.com/2213131

const session = await stripe.checkout.sessions.create({
  payment_method_types: ["card"],
  line_items: [{
    name: product.title,
    description: product.description,
    images: [product.photo],
    amount: product.price * 100,
    currency: "usd",
    quantity: 1
  }],
  success_url: "http://localhost:3000/success?session_id={CHECKOUT_SESSION_ID}",
  cancel_url: "http://localhost:3000/cancel"
});

由于某种原因，图片总是空的

其他数据没问题

1. 我使用 next.js auth0 和自定义 golang api 后端，但在后端获取解码令牌时遇到问题。
2. 在前端方面，我遵循了本教程 - https://auth0.com/docs/quickstart/webapp/nextjs/01-login
3. 我成功地将 accessToken 发送到我的后端 API
4. 在后端，我遵循了本教程 - https://auth0.com/docs/quickstart/backend/golang/01-authorization
5. 中间件已成功验证令牌

auth0 实现的中间件示例

func EnsureValidToken(next http.Handler) http.Handler {
    // EnsureValidToken is a middleware that will check the validity of our JWT.
    err := godotenv.Load()
    if err != nil {
        log.Fatal("Error loading .env file")
    }
    issuerURL, err := url.Parse("https://" + os.Getenv("AUTH0_DOMAIN") + "/")
    if err != nil {
        log.Fatalf("Failed to parse the issuer url: %v", err)
    }

    provider := jwks.NewCachingProvider(issuerURL, 5*time.Minute)

每次我在路由'localhost:8080 /'刷新一个html页面或登录用户我都会收到此错误:发送后无法设置标题.据我所知,这个问题是由于两次意外调用的回调而发生的.该应用程序不会崩溃或任何东西,它只是在控制台上记录相同的错误.

这是代码.

var User        = require('../models/user');
var Story       = require('../models/story');
var jwt         = require('jsonwebtoken');
var config      = require('../../config');


var superSecret = config.secret;


module.exports = function(app, express) {

    // creating our first router
    var apiRouter = express.Router();

    // signup a user

    apiRouter.post('/signup', function(req, res) {

            var user = new User({
                name: req.body.name,
                username: req.body.username,
                password: req.body.password
            });

            user.save(function(err) {
                if(err) res.send(err);
                res.json({ message: 'User has been created!' });
            });
    });

    apiRouter.get('/users', function(req, res) {

我将 twilio 用于 whatsapp API，但现在的问题是我不断收到此错误

错误：Twilio 找不到具有指定发件人地址的频道

这是代码

const express = require('express')
const accountSid = '-'
const authToken = '-'
const client = require('twilio')(accountSid, authToken)
const request = require('request')

const app = express()


app.get('/test', (req, res, next) => {
    client.messages
      .create({
        body: 'Hello there!',
        from: 'whatsapp:+14155238886',
        to: 'whatsapp:+myNumber'
      })
      .then(message => console.log(message.sid))
      .done()

      res.json('Done')
})

app.listen(3030, (err) => {
    if (err) {
        console.log(err)
    } else {
        console.log('Connected to the port 3030')
    }
})

我该怎么办？
