我创建了一个新的Lumen 5.4项目并尝试播种一些数据.在播种机中,我使用bcrypt来哈希密码.但是当我跑步时php artisan db:seed,我收到了这个错误:

Call to undefined function bcrypt()

为什么我不能在流明中使用bcrypt？我之前在Laravel中使用过它.

我正在尝试创建一个MEAN crud操作.我在节点中有一个带有删除http方法的api localhost:3000/api/user?id=<some document id>.下面是我使用的角度代码:

deleteUser(user) {
    console.log("user to delete:" + user._id);
    let myParams = new URLSearchParams();
    myParams.append('id', user._id);
    return this.http.delete('/api/user', { search: myParams })
      .map(res => res.json());
}

正确的ID正在打印到控制台,但我甚至无法看到在Chrome网络栏中进行的呼叫,也没有删除数据.出了什么问题？

我试图让服务器安装无头镀铬,selenium webdriver和量角器,以实现自动化测试.

我按照这些说明设置了我的环境:

# JDK 8
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update && sudo apt-get install openjdk-8-jdk

# Node JS
curl -sL https://deb.nodesource.com/setup_6.x | sudo bash -
sudo apt-get install -y nodejs

# NPM modules
sudo npm install protractor -g
sudo npm install chromedriver -g

# Google Chrome
echo "deb http://dl.google.com/linux/chrome/deb/ stable main" | sudo tee -a /etc/apt/sources.list
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
sudo apt-get update
sudo apt-get -y install libxpm4 libxrender1 libgtk2.0-0 libnss3 libgconf-2-4 …

我正在尝试集成node-postgres驱动程序并学习做一个简单的 CRUD 操作。在我的app.js，我做这样的事情：

...
var postgres = require('./adapters/postgres')
var postClient = new postgres(conf);
...
postClient.connect(function (dbconn) {
    app.dbconn = dbconn;
    app.conf = conf;

    console.log("************************************************************");
    console.log(new Date() + ' | CRUD Server Listening on ' + conf['web']['port']);
    console.log("************************************************************");

    server.listen(conf['web']['port']);

    var Routes = require('./routes/http-routes');
    new Routes(app);
});

在我的adapters/postgres.js文件中，我有以下内容：

const Client = require('pg');
const postClient = new Client(conf)({
    host: conf['postgres'].host,
    port: conf['postgres'].port,
    dbname: conf['postgres'].dbname,
    username: conf['postgres'].username,
    password: conf['postgres'].password,
    dbconn: null,
});
module.exports = postClient;
postClient.prototype.connect = function …

我有一个使用express和运行的Node应用程序jsonwebtoken.在每次请求api调用jsonwebtoken之前,我都进行了检查.我已手动排除下面的路线.有没有更好的方法从这里排除一些路线？我怎样才能做到这一点？

import * as express from 'express';
import * as jwt from 'jsonwebtoken';

import UserCtrl from './controllers/user';

export default function setRoutes(app) {

  const router = express.Router();

  // route middleware to verify a token
  router.use(function (req, res, next) {
    if ((req.method == 'POST' || req.method == 'OPTIONS') && (req.url == '/user' || req.url == '/login' || req.url == '/user/activate')) {
      next();
    } else {
      // check header or url parameters or post parameters for token
      var token …

我想将整数转换为二进制字符串.我选择使用java允许的本机函数Integer.toBinaryString(n).但不幸的是,这会从我的输出中减少前导零.让我们举例说,我给输入18,它给我输出10010但实际输出应该是010010.将int转换为字符串是否比编写用户定义的函数更好/更短？或者我在这里做错了什么？

int n = scan.nextInt();
System.out.println(Integer.toBinaryString(n));

我为特定用户的所有地址列表创建了一个集合,并将其命名为:

$addresses = collect($user->GetAddress);
$addresses = $addresses->where('deleted', 0);
$addresses = $addresses->except(['deleted', 'created_at', 'updated_at']);

我得到的输出如下:

[
        {
            "id": 1,
            "user_id": 1,
            "name": "mr.test",
            "line1": "test1",
            "line2": "test2",
            "pincode": 100,
            "city": "test3",
            "state": "test4",
            "mobile": "test5",
            "default": 0,
            "deleted": 0,
            "created_at": "2017-02-23 09:20:09",
            "updated_at": "2017-02-23 09:20:09"
        }
]

它仍然返回我做的字段,除了.我究竟做错了什么？

我甚至试过这些:

$addresses = $addresses->each(function ($item, $key) {
    return $item->except(['deleted', 'created_at', 'updated_at']);
});

和

$addresses = $addresses->each->except(['deleted', 'created_at', 'updated_at']);

所以我试图通过创建一个应用程序来学习一些基本的Angular,该应用程序使用OpenWeather API获取并显示某个位置的当前天气.

这就是我目前代码中的内容:

app.component.ts:

import { Component } from '@angular/core';
import { WeatherService } from './weather.service';    
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
  providers: [WeatherService]
})    
export class AppComponent {
  title = 'Ng-Weather';
  cityName: string;
  weather: Weather;    
  constructor(private weather: WeatherService) { }    
  search() {
    this.weather.getWeatherbyName(this.cityName)
      .subscribe(res => this.weather = res);
    console.log(this.weather);
  }
}

weather.service.ts:

import { Injectable } from '@angular/core';
import { Http, Response, URLSearchParams } from '@angular/http';
import { Observable } from 'rxjs';
import { Weather } from './weather'; …
