我正在尝试使用POST请求批量导入localhost:9200/products/product/_bulk以下JSON:

[
  { "index": {"_index": "products", "_type": "product", "_id": 1} },
  { "title": "Product A","description": "Brand A - Product A - 1.5 kg","price": 3.49,"sku": "wi208564","supermarket": "AJ","categories": "Fruit AJ","product_type": "Sinaasappels - mandarijnen","brand": "Brand A\n"},

*我希望在我的Sinatra应用程序中运行自定义Rake任务但我会继续rake aborted! Don't know how to build task 'greet'.

这是greet.rake用于测试目的的自定义Rake任务():

task :greet do
  puts "Hello!"
end

我已经把greet.rake在./lib/tasks(滑轨).我猜Rake无法找到该文件的正确目录.

如何在Sinatra中运行自定义Rake任务？

我正在使用Ruby 2.0.0和Sinatra 1.4.4.

UPDATE

Rakefile现在看起来像这样:

require "./app"
require "sinatra/activerecord/rake"
require "./lib/tasks"

使用时:

rake greet

我明白了:

rake aborted!
cannot load such file -- ./lib/tasks

我正在使用smart-location-lib来获取设备的当前位置.它需要在活动的生命周期中稍后使用.

一旦这样finish()的活动回到以前的活动,我收到了内存泄漏.

这是代码:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...

    SmartLocation.with(this).location()
    .oneFix()
    .start(new OnLocationUpdatedListener() {
        @Override
        public void onLocationUpdated(Location location) {
            mCurrentLocation = location;
        }
    });

    ...
}

...

@Override
protected void onStop() {
    super.onStop();

    SmartLocation.with(this).location().stop();
}

正如你可以看到我在做智能位置LIB的.stop()在活动的的onStop()的文档中描述称这里.

但这并不能防止泄漏.以下是LeakCanary收集的泄漏信息:

关闭python 3程序时,我在控制台中遇到一个奇怪的异常.

Python 3代码:

from tkinter import *
from random import randint

# Return a random color string in the form of #RRGGBB
def getRandomColor():
    color = "#"
    for j in range(6):
        color += toHexChar(randint(0, 15)) # Add a random digit
    return color

# Convert an integer to a single hex digit in a character
def toHexChar(hexValue):
    if 0 <= hexValue <= 9:
        return chr(hexValue + ord('0'))
    else: # 10 <= hexValue <= 15
        return chr(hexValue - 10 + ord('A')) …

我正在尝试使用rest-client lib 从Waze应用程序获取我的GPS数据.我基本上试图通过网站https://www.waze.com/伪造登录.登录后(您可以使用JohnDoeSpeedy228:gre @ tStory92)访问https://www.waze.com/editor/后,在查看网络调用后点击"驱动器",即可查看原始JSON数据.

我似乎已成功登录,但在发出请求返回所有驱动器的列表时,它返回以下内容

{"users"=>{"objects"=>[]}, "archives"=>{"totalSessions"=>0, "objects"=>[]}}

它应该返回这样的东西:

{
   "users":{
      "objects":[

      ]
   },
   "archives":{
      "totalSessions":1,
      "objects":[
         {
            "id":<REDACTED>,
            "userID":<REDACTED>,
            "existingRoadMeters":2839,
            "newRoadMeters":0,
            "totalRoadMeters":2839,
            "startTime":1456996197000,
            "endTime":1456996636000,
            "hasFullSession":true
         }
      ]
   }
}

这是我正在尝试的:

require 'rest-client'
require 'json'

GET_CSRF_URL = "https://www.waze.com/login/get"
SESSION_URL = "https://www.waze.com/login/create"

我有一个 Spring Boot 控制器，其端点接受以下配置类（作为 json）。该类具有参数maxIterations并将@Size注释设置为9000。

...
import javax.validation.constraints.Max;
import javax.validation.constraints.Size;

public class Configuration {
    // Max iterations
    @Size(max = 9000)
    private Integer maxIterations;

    ...
}

问题是，当使用POST以下命令调用该端点时json，它不会返回错误或警告，说明参数maxIterations高于9000。

{
  "maxIterations": 15000
}

这是我的控制器：

@PostMapping()
@ResponseStatus(HttpStatus.CREATED)
public String doSomething(@RequestBody Configuration configuration) {
    ...
}

可能是什么问题？

在./config/initializers我创建了一个名为的文件中task_scheduler.rb,它包含以下代码:

require 'rufus-scheduler'
require 'mechanize'

scheduler = Rufus::Scheduler.new

scheduler.every("1h") do
    puts "Starting Rufus Scheduler - Task 1 - Checking exampleShop for new orders"

    a = Mechanize.new

    a.get('http://exampleshop.nl/admin/') do |page|

        # Select the login form
        login_form = page.forms.first

        # Insert the username and password
        login_form.username = 'username'
        login_form.password = 'password'

        # Submit the login information
        dashboard_page = a.submit(login_form, login_form.buttons.first)

        # Check if the login was successfull
        puts check_1 = dashboard_page.title == 'Dashboard' ?  "CHECK 1 DASHBOARD SUCCESS" …

我正在尝试将Searchkick添加到我的 Rails 应用程序中。我正在按照“入门”页面上的确切说明进行操作，但不断收到以下错误：

这就是机场控制器的样子：

更新： 这只是创建 btComputePayment 时的一个错字。

解决了

我正在使用“Python 编程简介（Pearson 2013）”一书学习 Python。

目前我正在做一个练习，我必须在 Tkinter 中编写一个贷款计算器。

我似乎无法让以下代码工作：

from tkinter import *

class LoanCalculator:
    def __init__(self):
        window = Tk()
        window.title("Loan Calculator")

        # Create labels
        Label(window, text = "Annual Interest Rate").grid(row = 1, column = 1, sticky = W)
        Label(window, text = "Number of Years").grid(row = 2, column = 1, sticky = W)
        Label(window, text = "Loan Amount").grid(row = 3, column = 1, sticky = W)
        Label(window, text = "Monthly Payment").grid(row = 4, column = 1, …

我正在使用"使用Python编程简介(Pearson 2013)"一书学习Python.我在Mac OS X(10.8)上使用PyCharm 2.7来编写Pyhon 3代码.

以下代码(使用tkinter创建GUI并添加弹出菜单)在Mac OS X上无法正常运行.问题是按下鼠标右键时弹出菜单不显示.我在Windows 7 VM和Windows 7上测试了代码,它运行得很好.

所以我的问题是:为什么代码适用于Windows 7但不适用于Mac OS X？

这是代码:

from tkinter import *

class PopupMenuDemo:
    def __init__(self):
        window = Tk()
        window.title("Popup Menu Demo")

        # Create a popup menu
        self.menu = Menu(window, tearoff = 0)
        self.menu.add_command(label = "Draw a line", command = self.displayLine)
        self.menu.add_command(label = "Draw an oval", command = self.displayOval)
        self.menu.add_command(label = "Draw a rectangle", command = self.displayRectangle)
        self.menu.add_command(label = "Clear", command = self.clearCanvas)
